finely punctulate, the others very
faintly covered with dark pubes-
cence. Prothorax opaque, covered
with very fine delicate ridges which
run together so as to form a reti-
culation ; the disc strongly raised
in the middle and furnished with
three more or less glossy tubercles ;
the median tubercle narrow, elon-
gate and impunctate, the lateral
y. 74 two, which lie a little in front of

Euryphagus lundii, Fab. the middle, rounded and punctate.

Scutellum rugulose-punctate.
Elytra entirely opaque, rather densely punctate, the punctures
visible only on the red anterior portion, not on the posterior
black part, the latter rather densely covered with very short black
pubescence. Mesothorax, metathorax and abdomen covered faintly
with grey pubescence. Legs glabrous, glossy, very minutely and
very sparsely puuctulate.

c? . Head and prothorax of a dull red, slightly purplish, colour ;
elytra entirely fulvous-red ; scutellum black ; antennae glossy, the
first joint red, the rest black ; body beneath dull red, with the
sides of the meso- and metathorax black ; femora red, except at
the base ; tibiae and tarsi dark brown or black. Head subnitid at
the sides, opaque above ; the clypeus and occiput rather densely
punctate, the front almost impunctate. First antennal joint
sparsely punctate. Prothorax very densely rugulose-punctate ;
the disc less strongly raised than in the $ , but similarly provided
with three subnitid tubercles, and with an obtuse, feebly elevated
ridge behind each of the dorso-lateral tubercles. Elytra less
closely punctured than in the $ . The male differs further from
the female by the structural characters pointed out in the
description of the genus. These characters, such as the great size
of the head and mandibles, are most pronounced in large fully
developed specimens, but are less obvious in males of minor

Length rf $ 13-22 ; breadth 5-8| mm.

Hab. Assam ; Burma : Ruby Mines (Doherty).

This species differs from E. maxillosus, Oliv., in the entirely red



prothorax in both sexes, and in the elytra of the males, which are
without spots posteriorly. The males appear to be much less
numerous in collections than the females, and those described
above are considered to belong to the species because they have
coine from the same localities as some in the same collections.


Head more or less distinctly raised between the antenna? ;
the clypeus rather large, prolonged anteriorly some distance
beyond the base of the mandibles ; eyes finely facetted, deeply
emarginate, the lower lobes generally large, extending to the front;
outer lobe of maxilla? long, with brush of hairs at the end ;
maxillary palpi usually longer than the labial. Prothorax gener-
ally tuberculate at the sides. Scutellum usually rather large,
triangular in form, the sides straight or slightly curved, the apex
acute. Front coxa? globular, not prominent ; their acetabula
rounded on the outer side, closed, or very nearly closed, poste-
riorly. Acetabula of middle coxae extended to the epimera. Legs
long or moderately long ; their tibia? compressed. Metasternum
provided with scent-pores. "Wings with vein Cu 1 simple, Cu 2
absent. Male with six, visible ventral segments to the abdomen.

This group is well represented in the African and Oriental
Eegions, less well in Tropical America and by a few species only
in the Holarctic and Australian Eegions. The species as a rule
are characterized by a metallic coloration, varied in some cases by
yellow or fulvous bands or spots on the elytra.

Black and dull above, with two yellow bands that cross the elytra,
one about midway between the middle aud the base, the other a
very short distance behind the middle ; the first band somewhat
narrower than the second, which is variable in width but usually
extends to about a fifth part of the
whole length of the elytra ; first four
joints of the antennae and the base of
the fifth black, the rest fulvous ; legs
black and glossy, with the tarsi testa-
ceous yellow ; body beneath violaceous-
or steel-blue, with the abdomen of the
d 1 testaceous, that of the $ blue,
the hind borders of the segments

206. Zonopterus consangninens, Ritsema, Notes Leyd. Mu*. xi, p. 10

Closely allied to and very like Z. flavitarsis, but differs as follows :
First five or six joints of the antennae black; the anterior
yellow band of the elytra somewhat narrower. Prothorax more
regularly rounded at the sides. Scutellum narrower, depressed
along the middle with the edges raised, much less densely punc-
tulate. Femora more finely and less closely punctured.

The elytra in this species sometimes show a decidedly bluish
tint, especially near the apex.

207. Zonopterus redemanni, Nonfried, Deut. ent. Zeit. xxxv, P . 275

$ . Dark blue or violaceous-blue above, somewhat glossy, nearly
bare of pubescence ; with two yellow bands that cross the elytra,
the first nearly midway between the base and the middle, the
second a very short distance behind the middle ; first five or six

K" ints of the antennae black, the rest tawny ; body beneath steel-
ue, glossy, very faintly pubescent ; legs black or bluish black,
with the tarsi testaceous yellow. Puncturation of the head, pro-
thorax, and elytra very much as in Z. favitarsis, Hope, but a little
stronger and more conspicuous owing to the absence of a toinen-
tose covering. Prothorax transverse, slightly protuberant at the
middle of each side ; the disc with a slight transverse prominence
on each side just in front of the basal constriction and with two
feeble tubercles, more finely punctured than the rest of the surface,
near the apex. Femora finely and rather sparsely punctate, the
hind pair reach to a little beyond the hind border of the second
elytra! band.

Length 35-40 ; breadth 10-1 0| mm.

Hob. Ceylon.

In general form and structure this species comes very near
Z. consanguineus, and is chiefly distinguishable from it by its
larger size, by the upper surface which is almost bare of pubescence,
and the puncturatiou, which is consequently much more distinctly
visible. The author of the species has described the prothorax as
elongate and strongly convex, but in the female at least the width
across the middle is a littfe greater than the median depth, and
the disc is not more convex than in other species, rather the

208. Zonopterus corbetti, sp . n.

Dark metallic green or blue, with two broad yellow bands of
variable width on the elytra ; legs black, with the tarsi testaceous ;
last five joints of the antennae testaceous ; the yellow elytral
bauds in some specimens coalesce at the sides and suture and are
so much extended that the elytra may be described as yellow, with
the apical fourth, a narrow band at the base, and a transverse
spot just before the middle of each, dark blue ; in other specimens
the yellow bands are not broader than the sub-median blue baud
which separates them, and become slightly narrower towards the
suture ; the basal blue band and the sub-median band are slightly
pointed posteriorly at the suture. Head closely and rather finely
punctured. Antennae not so thick as usual for this genus, reaching
to a little beyond the middle of the elytra in both sexes ; joints
fifth to tenth feebly angulate in front at the apex. Prothorax
closely and finely punctured above, sparsely beneath in the $ ,
very densely beneath in the d" . Elytra also finely and very
closely punctured. Breast and abdomen with a fine grey

past the middle of the elytra in the $ ; fourth and fifth joints
narrower than the third, very slightly angulate at the apex ; sixth
to tenth broader, somewhat compressed, acutely angulate at the
apex on the anterior side. Prothorax with a short obtuse tubercle
at the middle of each side, densely rugulose-punctate above, some-
what transversely rugulose near the basal margin ; its length a
little greater than its width at the base. Seutellum subnitid.
Hind femora moderately thickened, finely punctulate, extending
in the <5 up to and in Hue with the front border of the dark-blue
apical area of the elytra. First joint of hind tarsus longer than
the next two joints united. Intercoxal process of prosternum

Range. That of the type species.

Though not considered distinct by Lacordaire, this genus
differs from Pachyteria, Serv., by well-marked structural characters.
The head is rather broad, and not narrowed and elongated
in front ; the clypeus is short, with a slight projection at the
middle of its front margin; the membranous epistome rather
broad and the labrum small ; the mandibles are robust in the male,
and differ in shape from those of Pachyteria the outer border
of each forms an almost continuous curve and each is armed
with a strong tooth on the inner side. The antennaa are very
thick like those of Pachyteria but much shorter, those of the male
not extending past the middle of the elytra ; they are gradually

narrowed from the fourth joint up to the apex. The acetabula of
the front coxse are open posteriorly.

rounded in the middle, the anterior and posterior transverse
grooves rather shallow, the disc slightly raised on each side just
in front of the posterior groove. Elytra gradually narrowed pos-
teriorly, rounded at the apex. Body beneath faintly covered
with silky greyish pubescence. Femora densely punctured, the
