42 HETEROMERA. [Anisoxya 
genus, which may be known by the very short mesosternum and the 
very small third joint of the antenne ; the prosternum is very short 
before the anterior coxe; the maxillary palpi have the last joint securi- 
form; the thorax is not transverse and has the sides rather sharply, 
although narrowly, margined as far as the anterior angles; the inter- 
mediate tibiz are stout and armed at apex with strong spurs, and the 
posterior are terminated by small, but distinct, spnrs ; our single species 
is very rare, and much resembles in general appearance a small Orchesia 
or Clinocara. 
A. fuscula, Ill. (tenuis, Rosenh.). A small and inconspicuous 
species, resembling in shape a small Clinocara,; elongate, convex, but 
slightly depressed on disc, scarcely shining, very finely and subrugosely 
punctured, clothed with silky yellowish-grey pubescence, colour fuscous- 
brown or castaneous with the front of the head and the anterior margin 
of thorax testaceous ; antenne reaching to about base of thorax, sub- 
moniliform and not or scarcely thickened, fuscous with base testaceous; 
thorax about as long as broad, with sides rounded and narrowed in front; 
elytra as broad at base as base of thcrax, subparallel for two-thirds of 
their length, and thence gradually narrowed to apex ; legs slender, yellow. 
L, 2-24 mm. 
In dead twigs, &c.; rare; Darenth Wood, Forest Hill, Putney, Lee, Horsell

Blatch). 
ABDERA, Stephens. 
This genus contains six species, all of which are found in Europe ; two 
of these, A. affinis and A. flexuosa, were separated off under the genus 
Carida by Mulsant, who is still followed by Thomson and other authors ; 
the latter genus, however, hardly seems to be really distinct; the 
members of the genus Abdera are small, elongate insects with more or 
less distinct yellow bands on the elytra ; the mesosternum is as long as 
the intermediate coxe, and the prosternum is very short before the 
anterior cox; the thorax is variable in length, but usually produced 
and rather strongly rounded in front; the last joint of the maxillary 
palpi is slightly securiform ; the legs are slender and moderately long, 
and the penultimate joint of the tarsi is almost, or quite, entire. 
The larva and pupa of A. jlecwosa are described and figured by Schiddte (xi. 
pp. 578, 587, t. xviii. 6 and 14); the larva is parallel with the segments, except the 
hinder ones, a little incised at their joints, of a membranous consistency, except the 
head and legs, which alone are corneous ; the colour is whitish with the head and 
legs pale yellow and the frontal margin ferruginous ; the head, which is moderately 
large, prothorax and eighth and last segments of abdomen are smooth on the surface ; 
the last segment is small, almost semicircular, and quite simple at apex ; the pro- 
thorax is rather large and narrowed in front with all the angles rounded; the sides 
of the segments are furnished with setose warty prominences ; the pupa is remarkable 
for having very small “styli motorii’’ on the pronotum only ; on the rest of the 
body they are absent 5 the apex of the abdominal region is terminated by four curved 
prominences; the larva lives in boleti.
