HETEROMBRA. [AnitOXIJO. 



genus, which may be known by the very short mesosternum and the 

 very small third joint of the antennae ; the prostenmm is very short 

 before the anterior coxae ; 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 tibiae are stout and armed at apex with strong spurs, and the 

 posterior are terminated by small, but distinct, spurs ; our single species 

 is very rare, and much resembles in general appearance a small Orchesia 

 or Clinocara. 



A. fuscula, 111. (tennis, Kosenh.). 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 ; antennae 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 thorax, subparallel for two-thirds of 

 their length, and thence gradually narrowed to apex ; legs slender, yellow. 

 L. 2-2i mm. 



In dead twig's, &c. ; rare; Darenth Wood, Forest Hill, Putney, Lee, Horsell

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 coxae, and the prosternum is very short before the 

 anterior coxae; 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. flexuosa are described and figured by Schiodte (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 ; the apex of the abdominal region is terminated by four curved 

 prominences; the larva lives in boleti.
