Selandria lineolata, Za4-, Beschr., 32, fig. 14 (lar.) ; Giraud,
Ann. Soc. Ent. Fr., 51, i, 380386
(as bipunctata); Kalt., Pfl., 664.

Blennocampa lineolata, Cam., Proc. N. H. S. Glas., iii, 109;
Fauna, 26, 9.

Black, shining, covered with a close grey pile ; abdominal segments
lined with a white pubescence ; tegulse, edge of pronotum, knees and
tibiae white ; apex of posterior tibiae and the tarsi fuscous. Antennae
shorter than the abdomen, the third joint one and a quarter times
longer than the fourth. Wings hyaline, iridescent; the costa, stigma
and nervures black ; third cubital cellule much longer than second.

Length 2| lines.

This species may be known from alchemillce by the
antcnnee being shorter than the abdomen ; the radial
nervure is received near the middle of the third cubital
cellule ; the second cubital nervure runs parallel with
the third and not with the first ; the second recurrent
is received nearer the second cubital, and the first
nearer the first cubital; while there is the decided
difference in the neuration of the posterior wings.
From bipunctata it is readily separated by observing
that the third cubital cellule is much longer than the
second, the opposite being the case with bipunctata,
which has it also broader compared to the length ; the
accessory nervure in hind wings is slightly longer
appendiculated. The $ of bipunctata has the antennae
shorter, thicker, and more compressed than in lineolata,
and the femora are reddish, lined with black.

242 BLENNOCAMPA BIPUNCTATA.

The larva appears in June feeding on oak leaves.
It is green, with a yellowish dorsal line, through which
the food canal shines as a dirty dark green line. On
each side of the dorsal line stand five lines of thorns,
and next to them, on the sides, are two rows of smaller
thorns; while over each proleg are placed two black tuber-
cles, placed one behind the other, the front one bearing
a split and the posterior a single thorn. Those on the
posterior segments are green ; under these are two
green single thorns. Upon the last segment are six
single thorns arranged in a half circle. The feet have
brownish claws, and have, at their base, an irregular
brown splash. Head brown, slightly pilose, darker
above and at the sides as well as at the mouth ; the eye
spots are large and black. After the last moult the
larva appears deep green with a deep orange-yellow
back and dark green dorsal stripes ; the head is deep
green.

This is not a common species. I have seen it from
Worcester, from Perth and Thornhill.

Continental distribution : Germany, France.

Black, shining ; tegulse, pronotum broadly, knees and tibise yellowish-
white; the tarsi and apex of posterior tibiae fuscous. The body is
covered with a greyish pile ; blotch moderately large ; abdomen slightly
broader in the middle than at the base, narrowing again from the apex
of the fourth segment to the apex, which projects sharply above.
Wings hyaline and slightly greyish ; sometimes the tegulse are of this
colour ; third cubital cellule much shorter and wider than second. The
palpi are pale.

Length 3i lines.

Apparently it is not common in this country. I
have only seen two specimens ; one from Kinguessie
and the other from Rannoch ; the former taken on the



BLENNOCAMPA BIPUNCTATA. 243

rose and the other on alder. On the Continent it is
found in Sweden, Germ; my and France.

I do not know that anything for certain can be said
to be known regarding its early stages. Dours (Cat.
Syn., p. 18) says that the larva feeds on roses, but
whether this is an actual observation of his own, or
merely copied from Boisduval, I do not know. The
last-mentioned author describes the larva as feeding on
rose twigs, but the description which he gives of the
larva and its habits agrees so closely with that of
Poecilosoma candidatum that I think he must have
mistaken the latter for bipunctata, which it is not
unlike.

The synonymy of this species is rather confusing.
Andre quotes lineolata, Zad., ? , and pubescens, Zad.,
J , as synonymous ; but the species I have described
above is neither the one nor the other, nor possibly is
it even his bipunctata, for he describes the 3 as having
an open discoidal cellule. Lineolata, Zad., on the
other hand, is the same species I have described under
that name ; while, according to Zaddach, pubescens $
has an open discoidal cellule, and has, judging from
his figure, the third cubital cellule longer, being as
long, if not longer, than the second. Giraud (Ann.
Soc. Ent. FT. (5), i, 380386) says that what Zad-
dach has described as the <? of pubescens is the <? of
lineolata, which is, according to him, only a var. of
bipunctata ; but the latter observation is certainly incor-
rect, although he may be correct in his former state-,
ment. Andre again quotes albipennis, Zad., as a syno-
nym of lineolata, KL, Htg., non Zad., because, I pre-
sume, Hartig makes lineolata a Blennocampa. If this
be really the case then lineolata, Zad., Cam., will
require a new name ; but in the absence of definite
information to the contrary (and it must be remem-
bered that practically lineolata <$ is a Blennocampa,
and that my lineolata agrees perfectly with King's
description, where no mention is made of the neuration
of posterior wings), I prefer to retain the name. My



244 BLENNOCAMPA RUFICRURIS.

bipunctata is certainly identical with the bipunciata of
Klug, Hartig and Thomson.



10. BLENNOOAMPA RUFICRURIS.

^Beschr., 35. ^
Blennocampa ruficrwris, Andre, Species, i, 302 ; Cat., 38,* 26.

Black. Antennae filiform, thin, of nearly equal thickness, the joints
distinctly separated, truncated and enlarged at apex, the third joint
curved, a little longer than fourth. Head small, smooth, shining, covered
with a very short pale down ; sutures scarcely visible ; clypeus trun-
cated ; palpi pale at the apex. Thorax smooth, shining, scarcely pubes-
cent, the basal half of pronotum broadly, and the tegulse testaceous ;
cenchri small, white. Abdomen nearly a third longer than the head and
thorax, smooth, shining; saw largely projecting, pilose. Legs: coxae, tro-
chanters, and basal three-fourths of femora (less than three-fourths of
anterior) black, apex of femora, tibiae and tarsi brownish-testaceous ; the
apex of tibiae and the apical joints of tarsi fuscous ; spurs very short.
Wings subhyaline, costa (extreme base is pale), stigma and nervures
black; the second cubital cellule has the upper side longer than the
tipper side of the third ; the lower side is angled where it receives the
recurrent nervure, and is shorter than the lower side of the third ; the
tr. radial nervure is interstitial. In the apical part of the second cubital
cellule is a faint dot. The mesonotum (with scutellum) is faintly punc-
tured ; the pleurae are semi-opaque, pubescent.

The <$ has the antennae longer than the abdomen and slightly pilose.

Length 3| lines.

Ruficruris comes next to b^p^mctata 9 but it is larger,
the antennse are thinner, the joints more sharply sepa-
rated, the colour of the pronotum and tegulse is dif-
ferent ; the first recurrent nervure is received near the
middle of the cellule, and not in the basal fourth, and
the tr. radial nervure is joined to the third tr. cubital.

Seemingly a rare species. A specimen has been
taken by Mr. E. Parfitt in Devonshire, and another by
Mr. Bridgman at Norwich.

Continental distribution : Germany, Dalmatia, Morea.

Abdomen, thorax, legs and stigma, rufous; head and antennse
black. Tr. radial nervure received a little beyond the middle
of cellule; tr. median in basal third of cellule; accessory
nervure in hind wings interstitial; second and third cubital
cellules subequal above ; third much wider at apex than at
base. Antennae short, filiform ; third joint a little longer
than fourth; frontal sutures distinct. Clypeus slightly in-
cised at apex ; patellae distinct (Species 11).

Reddish-testaceous, pilose, shining; head, antenna, metanotum, a
large spot on the sternum, sheath of saw, a few marks on sides and
ventral surface of the abdomen, and the legs at the base, black. Abdo-
men of a paler colour than the thorax ; cenchri large. Antennae as
long as the abdomen, the third joint is a little longer than the fourth,
the remaining joints taper very slightly towards the apex. Wings
hyaline, nervures blackish, costa and stigma pale testaceous.

The $ has the thorax black, and the ventral segments of abdomen
pale.

Length 3 lines.

The larva is covered with black and green spines,
and feeds on the under side of oak leaves. The ground
colour is green ; the head is green, marked at the sides
and on the vertex with fuscous. The black spines are
on the back and sides, the green ones over the legs.
The former are paler at the base and apex, double
pointed, and arise from black tubercles. They are
arranged in two rows on a segment, but are not placed
exactly opposite each other, and one is placed by itself.
On the back there is a clear space in the centre. Over
each of the ventral legs are two rows of whitish-green
spines, mostly simple. The spines are more numerous
and more irregular on the thorax, and less numerous
over the last segment, on which they are partly simple,

partly bifid. There are six on the second segment, and
twelve on segments three and four. On the abdominal
segments there are six in each row of the black spines.
At the last moult the spines are all thrown off and the
larva becomes entirely green. The larva appears in
May and June, and pupates in the earth, where a
cocoon is spun.

and Mr. Bridgman not uncommonly near Norwich.

Continental distribution : Sweden, Germany, Tyrol,

Qbs. There are two Continental species with the abdomen yellow
closely allied to nigripcs, which may be expected to occur here. All
have the wings suffused with fuscous, and may be distinguished as
follows :

a. Legs black. Nigripes.

b. Legs reddish-yellow.

Abdomen entirely reddish-yellow. Croceiventris, Klug.

Belly only reddish -yellow. Spinola, Klug.

Apical segments and a row of spots on back black.

Fuscipennis, Fall.



Abdomen and legs luteous, thorax and head black. Antenna)
short, thick. Wings fuscous ; transverse radial nervure re-
ceived a little beyond the middle of third cubital cellule ; tr.
median nervure received in middle of cellule; third cubital
cellule longer than second, dilated at apex. Claws cleft. Apex
of clypeus truncated. Frontal sutures distinct. Body short,
thick, covered with a close black pile (Species 13).

Deep black, shining, pubescent, broad, short; the apical half of the
four anterior femora, the posterior almost wholly, and the tibiae and
abdomen, luteous ; the base and apex of the abdomen and a row of dots
along its back black. Antenna? as long as the head and thorax, thick-
ened towards the apex, the two apical joints being thicker than the pre-
ceding; the third joint is a little longer than the fourth ; the apical
joints are more closely united than the basal ones. Wings fuscous, the
nervures, stigma and costa black ; the tr. radial nervure is received a
little beyond the middle of the third cubital cellule.

the <?.

Continental distribution : Sweden, Holland, Ger-
many, France, Switzerland, Tyrol, Russia.



SECTION 2. Posterior Wings with no middle cellule.

Body and legs black, the knees paler, pronotum sometimes
reddish. Antennae shorter than abdomen, thick, not attenuated
at the apex. Transverse radial nervure received in apical
third of third cellule ; tr. median nervure received close to
middle of cellule ; accessory nervure in hind wing received in

Black, shining, scarcely pubescent ; knees and base of tibiae and ante-
rior tibiae (broadly) white ; prothorax and mesonotum (except scutel-
lum) blood red ; breast black. Antennae thick, a little longer than head
and thorax; attenuate towards the apex, the third joint a half longer
than the fourth, the rest a little shorter. Wings fuscous ; the tr. radial
nervure is received a little beyond the middle of the third cubital
cellule.

Length 21 lines.

This little species may be known from fuliginosa by
its smaller size, shorter antennas, much longer third
cubital cellule, distinct pentagonal area, and by the
blood-red coloration of thorax ; from cinereipes it may
be also known by the last-mentioned peculiarity ; it
has also a narrower, more rounded body, while the
scutelluni is punctured. The <$ is very rare.



BLENNOCAMPA OINEREIPES. 249

This seems to be a southern species. It is not un-
common, according to Stephens, in the London dis-
tricts. I have taken it in Gloucestershire.

Continental distribution : Sweden, Germany, Hol-
land, France, Italy, Russia.



Accessory nervure in hind wings received in apical third of
cellule ; second cubital cellule with a large black horny point.
Pentagonal area indistinct. Clypeus truncated (Species 15).

Deep black, shining, very slightly pubescent; knees and anterior
tibia) in front brownish-testaceous ; mandibles piceous. Wings faintly
fuscous. Antennae a little longer than the head and thorax, thickened
towards the apex ; the third joint is a little longer than the fourth. In
front of the scutellum are two deep punctures.

Length 4 lines.

The less pilose body and more uniformly- coloured
wings readily separate this species from nigrita, while
the piceous mandibles and a large, conspicuous, oblong
horny point in the second cubital cellule form also
distinguishing characteristics.

I believe this is not a common species in the north,
but is tolerably abundant in the south.

land, France, Hungary.

white ; terebra slightly projecting. & and cf .

Length 2 2f lines.

A species distinguished by its deep, black, short
oval body, thickish antennae, and the broad white ring
at base of tibise. At the base of the lanceolate cellule
is a curled-up impression of a nervure, which likewise
forms a distinctive peculiarity.

It is not uncommon among herbage in May, and
appears to have a wide distribution.

Continental distribution : Sweden, Germany, Hol-
land, France, Italy, Hungary, Russia.



Tegulae and extreme base of pronotum white ; apex of femora,
tibiae and tarsi, white. Antennae longer than abdomen, thin,

Black ; antennae filiform, longer than tlie abdomen ; the first joint
globular, much longer than the second, the third and fourth nearly
equal, the remaining joints nearly equal. Head a little narrower than
the thorax, smooth, shining, covered with a fine grey pile ; frontal
sutures distinct. Tegula) and basal edge of pronotum white ; scutellum
flat, very smooth and shining ; cenchii small, dull white. Abdomen a
very little longer than the head and thorax, saw projecting, hairy at the
apex ; sides of abdomen covered with a white pile. Legs : base of coxa?,
femora for the greater part, extreme apex of posterior tibia) and apical
joints of tarsi black ; apex of coxa), trochanters, knees, tibia) and base of
tarsi, white. Wings clear hyaline ; costa at base, and base of stigma pale
testaceous ; apex of stigma and nervures, black. The tr. radial nervure
is interstitial or received in the fourth cubital cellule ; the second recur-
rent nervure is received a very little in the front of cellule ; the second
cubital cellule is longer and thinner than third, and is angled where it
receives the recurrent nervure ; the third cellule is wider at apex than
at base; the second tr. cubital nervure is bent slightly downwards in
the direction of the base of the wing ; the third is curved in the middle,
and runs in the direction of the apex of the wing.

The J has the antenna) a little longer than the body, covered with a
short stiff pile, the joints thicker and more flattened than in the $ , their
general appearance being as in Priophorus (Cladius); genital parts
pale testaceous.

Length 24 2ft lines.

This species may possibly be identical with B. uncta,
King, but Hartig (Blattw., 269) describes the antennas
in the $ (the only sex he describes) as " etwas kiirzer
als der Hinterleib ;" and Thomson (Hym. Sc., i, 219)
as " longis, abdomine fere longioribus " in both sexes ;
whereas our species has them longer than the abdomen
in both sexes (in the $ as long as the entire body).
The only other species with which it can be confounded
with (belonging to the same section of the genus) is
B. sulserrata, which, however, has the third antennal
joint distinctly longer than the fourth, the legs black
at the base, the pronotum but very slightly marked
with white, cubital cellules broader, &c.

I bred this species from a green spiny larva which
fed on Alchemilla vulgaris, as described by Degeer






252 BLENNOOAMPA SUBCANA.

(Mem., ii, 245, 9, t. 35, figs. 1923) andEeaumur (Mem.,
v, 94, 95, pi. 12, figs. 13, 14), who, however, had not been
able to rear it. It is of the usual form, about four lines
long, entirely green, with white forked spines. The
head is of a darker green with a yellowish tinge ; the
eyes black. At the last moult the spines are thrown off,
and it becomes of a pale green colour. The pupa state
is passed in the earth, the imago emerging in June.

A common species in June. I have taken it on Ben
Clibrich, Sutherlandshire, on Alchemilla alpina. It is
widely distributed in England.



Tegulse and pronotum black ; apex of femora, tibiae and tarsi,
white. Antennae longish, the joints clearly separated, third
joint longer than fourth. Wings almost hyaline, transverse
radial nervure interstitial or nearly so ; third cubital cellule
not much longer than second, considerably widened at apex.
Clypeus slightly incised; frontal fovese distinct (Species 19
and 20).
