as long as broad ; head scarcely half as broad as the elytra ; thorax
a little narrowed from the base to the front, with a very slight sinua-
tiou of the sides in the front of the hind angles ; these about rect-
angular, but minutely rounded ; the lateral margin very fine ; the
front not emarginate ; the base a little sinuate on either side ; the
surface finely and not densely punctate, with a minute depression
on the base on either side of the middle ; scutellum transverse ;
elytra convex, each with eight series of foveiform punctures, some-

where about twelve punctures in each series ; those near the suture
and base finer, and those at the apex irregular, so that the surface
there is quite uneven. Legs glabrous, unicolorous-red.

Grey mouth. Helms. I first received this insect from Herr
Reitter ; and, as he wished a name proposed for it, I labelled it
" Adelium (?) variolosum :" on investigation it proves, however, to be
abundantly different from Adelium.

2059. C. genialis, n.s. Convex, oval, shining, glabrous ; head
and thorax aeneo-niger, elytra of a reddish hue, palpi and tarsi
fulvous, antennae and tibiae red, femora mostly piceous.

Head finely punctate. Thorax transverse, the sides but little
curved, straight behind ; anterior angles hardly at all depressed,
the posterior rectangular ; rather finely and not closely punctured,
and with a transverse impression on either side of the middle along
the base. Scutellum transverse, minutely punctured. Elytra
minutely punctured, and with eight rows of rather distant, irregular,
punctiform impressions, coarser near the sides and extremity, caus-
ing inequalities of surface behind. Tibia straight.

Underside black, shining, finely sculptured.

Allied to the typical species ; the prosternal process, however,
is not in the least impressed, the elytra are as glossy as the thorax,
and the legs are not concolorous.

Length, 3J ; breadth, If lines.

Mount Arthur. Two examples, one much mutilated, were
brought to me by Mr. T. F. Cheeseman.

2060. C. aeneUS, n.s. Oval, convex, nitid, greenish ; femora
piceous, tibiae and antennae red, tarsi and palpi fulvous.

Underside pitchy-black, shining, finely sculptured.

This species agrees in most respects with the description of C.
chrysomeloides, but the prosternal process is broadly grooved longitu-
dinally throughout, the elytra are quite glossy, the legs are not
uniformly coloured, and the five terminal joints of the antenna are
more obviously pubescent than the others. It is shorter and more
convex than C. genialis, with the thorax narrower in front and with
more depressed anterior angles; the sculpture, however, is quite, or
very nearly, similar.

Length, 3 ; breadth, 1-| lines.

Boatman's. Mr. A. T. Cavell was kind enough to send me three
specimens, which he detected under bark.



Group PEDILIIXffi .

Macr atria.

2061. ]V[. flavipes, n.s. Elongate; head and thorax black,
elytra piceous, the legs, palpi, and two basal joints of the antennas
yellow, the next three joints more or less fusco-testaceous, the
remainder fuscous ; pubescence greyish.



OF NEW ZEALAND. 1163

Bather larger and decidedly broader than M. verticalis ; the head
with more distinct punctures, the occiput less convex and with
very few punctures ; the eyes not quite as large and more widely
separated above ; the legs a little stouter, the posterior tibiae with
rather longer spurs ; the basal joint of the front tarsi slightly more
dilated ; the pubescence rather finer.

Length, If lines ; breadth, nearly -J- line.

Parua (Whangarei Harbour). One example.

Xylophilus.

2062. X. nitidus, n.s. Shining, clothed with minute grayish
hairs ; black, legs, palpi, and antennae yellowish.

Head broader than the thorax, distinctly but rather distantly
punctured. Antenna longer than the head and thorax, rather slender,
basal joint larger than second, third and fourth slender, subequal,
twice as long as broad, joints 5-10 decrease in length but become
broader, the tenth being transversely quadrate, eleventh broad, sub-
ovate. Thorax small, about as long as broad, more rounded and
narrowed in front than behind, without distinct lateral margins, its
punctuation closer and rather coarser (yet fine rather than coarse)
than that of the head. Scutellum smooth, subtriangular, but with a
truncate apex. Elytra ample, twice the breadth of the thorax,
widest behind, gradually narrowed towards the obtuse shoulders;
they are broadly impressed before the middle, and are distinctly
punctured, the punctures becoming finer and more distant towards
the extremity.

This and the following species cannot be referred to Westwood's
genus Euglenes on account of the structure of the antennae and
eyes, but they may, I think, be placed in Xylophilus.

The eyes are large and prominent, moderately widely separated
above, rotundate, a little notched in front, and distinctly facetted.
The antenna are implanted on the forehead near the front and inner
part of the eyes. The maxillary palpi have a large cultriform
terminal joint, which is united to the penultimate not in the middle
but at the side. The posterior tibia are gradually thickened, and
terminate on the inside in a conspicuous process ; the hind tarsi are
long, the basal joint being nearly the length of the tibia, the inter-
mediate are very short.

Length, 1 ; breadth, nearly line.

Northcote, Waitemata Harbour. One example.

2063. X. antennalis, n.s. Shining, fusco-niger, legs more or
less fuscous ; pubescence greyish ; palpi yellow, their last joints
infuscate.

Antenna rather longer than the head and thorax, basal joint
piceous, the following six testaceous, the remainder fuscous.

Allied to X. nitidus ; the head much broader, rather finely and
distantly punctured ; thorax shorter, transversely quadrate, mode-
rately punctured ; scutellum short, not at all triangular; elytra more



1164 COLEOPTERA

feebly impressed before the middle, their outline similar, but rather
narrower.

Length, 1 ; breadth, f line.

Paparoa, near Howick. One individual only.

2064. X. COloratUS, M.S. Fuscous, head and thorax somewhat
rufescent, base of elytra testaceous ; legs pale, yellowish, the hind
femora dark, sometimes piceous ; antennae rufo-testaceous, the basal
and terminal joints infuscate or reddish ; the body moderately
shining, with slender greyish pubescence.

Head very sparingly and finely punctured. Thorax about as
long as broad, distinctly but not closely punctured, with two more
or less confluent basal depressions, more feebly impressed near the
front. Scutellum subtriangular, its apex truncate. Elytra gradually
narrowed towards the front, about twice as broad as the thorax,
broadly, almost curvedly, impressed before the middle; they are
moderately closely punctured, the sculpture, however, becoming
finer and more distant behind. Eyes not distinctly emarginate.

Length, 1 ; breadth, f line.

Otago, Chalmer, one ; Mokohinou, Sandager, two ; and from
other localities in my own collection. The species is variable.

2065. X. pictipes, n.s. Castaneo-fuscoits,thQ shoulders paler;
legs testaceous, the posterior femora and the apical half of the inter-
mediate and hind tibiae infuscate ; antennae fuscous, the third joint
and the extremity of the next seven paler, the two basal joints
piceous ; pubescence greyish.

Head broad, indistinctly punctured, shining. Eyes very large.
Antenna stout, filiform, evidently longer than the head and thorax,
second and third joints short, 4-10 decrease in length, tenth obconi-
cal. Thorax quite as long as broad, narrowed near the front, uneven,
distinctly and moderately closely punctured, with three basal im-
pressions (one at the middle and one near each side). Scutellum
subtriangular/ truncate behind. Elytra nearly twice the breadth of
the thorax, curvedly impressed in front of the middle, distinctly
punctured, more closely near the base than behind. Tibia with a
short terminal process, the intermediate slightly curved.

Length, 1^ lines ; breadth, f line.

Howick. One example.

2066. X. Obscurus, n.s. Fuscous, head and thorax blackish
and shining ; legs and antennas fusco-testaceous ; elytral clothing
ash-coloured, slender, but rather dense, causing the elytra to appear
subopaque.

Head without distinct punctures. Thorax quite as long as it is
broad, with two large rounded impressions near the base ; it is
moderately closely punctured. Scutellum subtriangular, its apex
emarginate. Elytra oblong, but little narrowed in front, not twice
as broad as the thorax, broadly impressed before the middle, rather



OF NEW ZEALAND. 1165

closely punctured, less so behind. Antenna longer than the head
and thorax, stout, ninth and tenth joints transverse. Tibia with a
short apical process.

Length, ; breadth, f line.

Howick. Two specimens.



Group-ANTHICID^E .

Cotes.

2067. C. Optima, n.s. Elongate, rather glossy ; head aeneo-
fuscous, thorax more 'rufescent, elytra pale-brown, legs pale-testa-
ceous, antennae reddish.

Head as broad as thorax, much narrowed, but not abruptly
truncate, behind ; finely and distantly punctured. Antenna stout,
reaching backwards to intermediate femora ; second joint almost as
long as third. Thorax longer than broad, constricted behind the
middle ; its punctation closer than that of the head, almost dense
near the front and base ; its yellow pubescence most conspicuous
behind. Elytra widest before the middle, convex, densely covered
with depressed fulvous hairs, intermingled with some upright ones
which are most obvious behind ; distinctly but not coarsely punc-
tured, the punctuation, however, becoming obsolete behind the
middle. Legs stout.

C. vestita is described as opaque, with the head and thorax im-
punctate.

C. proba differs from the present species in having the coarser
punctures on the basal portion of the elytra disposed almost in rows.
The form of the hind-body is different, being broadest at the middle,
in one example probably a sexual variety even after the middle ;
the elytra are not convex, or only a trifle so, and are, moreover,
depressed behind the base. C. crispi and C. punctata are altogether
different insects.

Length, 3f lines ; breadth, nearly 1 line.

Howick. One individual, found underneath a log.

2068. C. punctata, n.s. Elongate, moderately shining, densely
covered with depressed and erect yellow hairs, those on head and
thorax much' more scanty ; head, thorax, and antennae reddish ;
elytra fulvous, but with the basal and middle portions more or less
infuscate ; legs and palpi fulvescent.

Head rounded behind the eyes, as broad as thorax, quite obso-
letely and remotely punctured ; the neck broad and coarsely sculp-
tured, as, indeed, is the case with the larger species. Antenna
moderate ; second joint distinctly shorter than third. Thorax of
normal form, the constriction accompanied by an obvious depression
across the surface, this narrowed portion quite evidently punctate.
Elytra broadest near the shoulders, which, however, are narrowed,
as is usual ; they are a little depressed before the middle, and have
several series of punctures which do not extend much beyond the



1166 COLEOPTERA

centre, the posterior sculpture being indefinite. Legs moderately
stout ; tibiae slightly bent, intermediate densely pubescent near the
extremity.

In C. optima the thoracic constriction does not cause any super-
ficial depression ; in C. proba the dorsal depression is not deep ; in
the formerly-described species the contraction is continuous, pro-
ducing a very evident transverse impression on the dorsum.

Length, 1-J-lf lines ; breadth, % line.

Howick. Two specimens, under logs.

2069. C. dorsale, n.s. Elongate, thickly pubescent ; head and
thorax a little shining, infuscate-red, the sides and basal portion of
the latter blackish ; elytra opaque, paler in colour ; legs testaceous ;
antennae, palpi, and tarsi testaceo-rufous.

Head as broad as thorax, frontal impressions well marked, not
perceptibly punctate, with some slender yellow hairs. Antenna
robust, elongate ; second joint two-thirds the length of third.
Thorax indistinctly sculptured; the middle of basal portion, and a
large, almost triangular, space on the frontal portion densely covered
with fine yellow pubescence ; the rest of the clothing less con-
spicuous, except, of course, the ordinary upright hairs. Scutellum
almost oblong. Elytra elongate, widest behind posterior femora,
yet not much broader there than elsewhere ; each with four dorsal
rows of distinct but not coarse punctures, becoming finer behind and
even quite obsolete at the extremity ; broadly impressed before the
middle, faintly fuscous behind that ; covered with greyish-yellow
hairs near the middle, the other parts with fulvous or reddish hairs,
many being erect and elongate ; the pubescence not straight, but
curled, as it were, yet lying flat on the surface.

Differs superficially from C. proba in coloration, in the peculiar
clothing of the elytra, shorter and broader thorax, longer scutellum,
and different elytral sculpture.

Underside dark-fuscous, abdomen paler, pubescence yellow. The
narrow excision of metasternum with slightly-curved edges and pro-
longed forwards as a fine channel ; the abdominal process triangular,
with a transverse elevation behind ; the basal segment nearly as
long as the following tw r o.

In C. proba the metasteroal excision is triangular with straight
sides, and the abdominal process is similar in form, quite simple, and
on the same plane as the segment itself.

Length, 2^ lines ; breadth, nearly f line.

Clevedon. I am indebted to Mr. Munro for two examples.

2070. C. distincta, n.s. Body slightly nitid ; pubescence
yellow, thicker on elytra than anywhere else, erect hairs numerous.

Head very indistinctly punctured. Thorax finely punctated.
Scutellum transverse. Elytra widest near the base, gradually at-
tenuated posteriorly, apices broadly rounded, almost truncate ;
punctuation somewhat irregular at base, more definitely serial near
the middle, becoming indistinct behind.



OP NEW ZEALAND. 1167

Coloration like that of C. proba ; shape and sculpture of hind-
body different.

Distinguished from all the other species by the rather slender
antenna, the second joint of which is about one-half the length of
the third ; this joint has a basal articulation distinctly marked off
from the joint itself, and which, under ordinary conditions; ts
received into the apical cavity of the first joint ; if these two por-
tions be taken together the second joint would equal the third in
length. This character, I notice, obtains in other species, but in my
specimen of C. distincta it is remarkably developed.

Length, 2J lines ; breadth, f line.

OBS. When examining the different species of this genus in my
collection I found that the scutellum offers a good differentiating
character. In C. crispi it is triangular ; in C. punctata it is shorter
and broader ; C. optima has a broadly-triangular one, rounded
behind.



2071. C. proxima, n.s. Nitid, testaceo-fuscous, slightly
bronzed, the head, thorax, and elytral suture rather more rufescent ;
femora testaceous ; tibiae, tarsi, antennae, and palpi rufo-testaceous ;
densely clothed with conspicuous fulvescent hairs.

Closely allied to C. optima, only differing therefrom by the closer
punctuation of the head and thorax, the latter being quite densely,
but finely, punctured.

Length, 3-| lines ; breadth, 1 line.

Mokohinou Island. One example ; Mr. Sandager.

2072. C. TTlfa, n.s. Shining, fusco-rufous, a broad space near
the middle of the elytra yellow ; pubescence yellow.

The head is unusually narrow and not perceptibly punctured. Eyes
rather small. Thorax small, longer than broad, its frontal portion
two-thirds of the whole size and quite globose ; the constriction near
the base is continuous, so that there is a deep channel across the
dorsum, the basal portion is broader than the other, and the surface
appears quite smooth. Elytra long and broad, oblong, rounded
behind ; broadly impressed before the middle, and with an impres-
sion near each shoulder, so that there seem to be two rounded,
obtuse, basal elevations near the scutellum ; on these the punctures
are much finer than those on the depressed parts, they are not
arranged in regular rows, though, here and there, they seem to be
so, the sculpture becomes finer after the middle, the apical portion
being smooth. Legs rather slender. Antenna extending backwards
beyond the middle thighs.

This species is remarkable on account of the small thorax, ample,
and not at all oviform, hind-body, and rather narrow head.

Length, 2| lines ; breadth, 1 line.

Described from an old damaged specimen sent by Mr. Sandager,
a/nd found by him most likely near Wellington.

1168 COLEOPTERA

Anthicus.

2073. A. anthracinus, n.s. Glossy, deep-black, legs and
antennae infuscate-black, knees and tarsi fuscous ; pubescence fine,
ash-coloured, but intermingled with some paler elongate hairs.

Head subquadrate, rounded behind, smooth. Antenna elongate,
second joint more than half the length of the third, which is nearly
similar to the fourth and fifth, eleventh acuminate. Thorax small,
rather longer than broad, rounded laterally, much narrowed in front,
with a deep, broad constriction at each side behind the middle ; it is
distantly and not very evidently punctured, almost in series near the
middle. Elytra elongate, nearly twice as broad as the thorax, ovi-
form ; their punctuation distinct, not close, not serial, and becoming
quite obsolete behind the posterior femora. Legs elongate, tibial
spurs minute ; basal joint of hind tarsus as long as the following
three.

Very much like A, obscuricornis .

Length, 1| lines ; breadth, \ line.

Boatman's. Discovered by Mr. Cavell.



2074. A. fallaXj n.s. Nitid, sparsely clothed with minute
greyish hairs ; variegate, head and most part of the elytra blackish ;
femora dark-brown ; the thorax, the humeral regions, tibiae, and six
basal joints of the antennae rufo- testaceous ; remaining joints of
these latter infuscate.

Head large, subquadrate, finely and moderately closely punc-
tured. Prothorax widest in front, much contracted just before the
base ; it bears two small frontal elevations, its punctation like that
of the head. Elytra ample, suboblong, broadest near the middle,
apices very obtusely rounded, slightly depressed before the middle,
and with an elongate sutural depression behind ; its punctation
distinct yet neither very close nor coarse. Pygidium much exposed,
finely and densely sculptured. Legs robust, intermediate tibiae
densely clothed with yellow hairs near the extremity.

This species is considerably larger than A. minor ; it, however,
more closely resembles the European A. floraiis, from which indeed
it only differs in coloration, in its much finer and less conspicuous
clothing, more robust legs, and much more protuberant anal segments.

Length, If lines ; breadth, quite J line.

Described from a specimen taken from a puriri log at Howick.

Group CISTELID^E.
Xylochus.

2075. X. spinifer, n.s. Body moderately shining ; head and
thorax fusco-niger, elytra nigro-fuscous, legs rufo-fuscous or piceous,
tarsi fulvescent, antennas reddish.

Head finely but not closely punctured. Elytra obviously striate-
punctate, the sutural striss most distinct, the scutellar series of
punctures elongate.



OF NEW ZEALAND. 1169

This species is like X. dentipes, but the sides of the thorax are
more . strongly rounded at the middle and more abruptly narrowed
behind, so as to appear as if obliquely sinuated near the base ; the
superficial sculpture too is different, being finer and less distinct.
The elytral punctures are larger, but the suture, near the hind slope,
is not so broad or convex.

The male has the armature of the front femora more conspicuous ;
instead of a blunt tooth-like projection, it has rather the appearance
of an outstanding spiniform process.

Female. Front tibiae straight, intermediate nearly so, the pos-
terior moderately curvate.

Length, 4 ; breadth, 1|- lines.

Mokohinou Island. Mr. Sandager was kind enough to send me
a pair.

Omedes.

Nov. gen.

Terminal joint of palpi wide in front, cultriform. Eyes nearly
rotundate, emarginate in front, large, with coarse facets, but not at
all prominent or convex. The space between the forehead and
labrum large, membranous. Prosternal process rather narrow be-
tween the coxae, deflected behind these, and then a little produced
and flattened, on a lower plane than in front. Intercoxal process of
abdomen almost triangular, narrower than in the genus Xylochus.
Spurs of the tibiae small. Claws of the tarsi finely pectinate.

This genus is established for species which cannot be placed in
Xylochus. Mr. Pascoe is of opinion that his genus Hybrenia is
closely allied to Xylochus, but I have not been able to see his
description. White's Tanychiltcs metallicus is not a true Tanychilus,
neither is No. 699.

2076. O. nitidus, n.s. Body nearly glabrous, shining, a little
convex, moderately elongate ; infuscate-black, legs and coxae pale-
castaneous, femora more infuscate ; tarsi, antennae, and palpi paler
than the tibiae, sometimes rufescent.

Head rounded behind ; finely, not closely, and somewhat irregu-
larly punctured ; the forehead broadly concave. Antenna pubescent,
stout, filiform, reaching backwards to the hind thighs ; second joint
one-third the length of the following one. Thorax rather broader
than long, curvedly narrowed near the front, nearly straight behind
the middle, finely, yet distinctly, marginated ; anterior angles de-
pressed and rounded, the posterior nearly rectangular, but blunt ;
base feebly sinuate ; there is a large puncture behind each eye, and
two shallow impressions behind the middle ; its punctuation is
rather fine, shallow, and distant, but there are some more distinct
punctures near the base. Scutellum broad, impunctate, somewhat
polished. Elytra a little broader than the thorax at the base, wider
still behind the middle, marginate, apices, singly, strongly rounded,
so as to expose the finely-punctate apical segment ; their series of
punctures moderately small, finer and more distant near the sides,



1170 COLEOPTEKA

the oblique scutellar series distinct ; the sutural striae are well
marked, especially behind where they, and one or two others, are
rounded ; interstices broad, not convex, densely and minutely sculp-
tured, and with a few very small punctures. Legs stout, simple,
finely pubescent.

Underside nigro-fuscous, middle of mesosternum more obviously
punctured than any other part of the breast.

Length, 3 ; breadth, 1^ lines.

Mokohinou Island. Mr. Sandager ; two examples.

2077. O. fuscatus, n.s. Subopaque, chestnut-brown ; legs,
antennee, and palpi chestnut-red.

Head rounded behind antennal orbits, finely punctured, trans-
versely depressed between the antennae. Thorax with two ill-
defined basal impressions, finely, distantly, and evenly punctured.
Elytra broadly impressed before the middle, bearing series of fine
punctures, these form two or three striae behind, which are more or
less bent or rounded near the extremity.

More depressed, rather broader, and duller than 0. nitidiis. The
head more closely punctured. Thorax rather shorter, less narrowed
in front. Elytra without scutellar (distinct) series of punctures,
their sculpture less regular, basal punctuation indefinite. In both
species there is a depression near each shoulder. The scutellum is
longer.

Length, 3-J-; breadth, 1J lines.

Hooper's Inlet, Port Chalmers. One individual, sent by Mr. T.
Chalmer, of Dunedin. A varietal form occurs at Moeraki Point, but
the specimens I have seen are not in such good order as to enable
me to determine whether they represent a distinct species. Two
examples were sent for inspection by Mr. Sandager.

Group (EDEMERID-ffi.

Exocalopus.

Nov. gen.

Allied to Techmessa, differentiated by the following characters :
Epistome limited in front by a sharply-defined, strongly-curved
channel with carinate edges ; the muzzle and labrum narrower.
Thorax bisinuate at base. Tibial spurs not distinct. Antenna
similar to those of Techmessa in the female sex, but strongly
pectinate among the males, in which sex the second and third joints
are very short and equal, joints 4-10 are furnished with an elongate
lobe, eleventh elongate.

Of all the published genera of the family this, no doubt, is the
most approximated to the Ehipiphorida ; no other possesses such
peculiarly-formed antennae.

2078. E. pectinatUS, n.s. Elongate, subdepressed ; shining,
