CTENOPLECTRA NITIDULA, sp. nov. 
9. Length about 6°5 mm.; robust; shining black ; hind margins 
of abdominal segments narrowly hyaline; small joints of tarsi ferru- 
ginous ; head very broad, much broader than long; mandibles dark, 
with a few long golden hairs beneath ; labrum large, shining, with a 
strong keel down the middle; clypeus strongly punctured, depressed 
apically ; front very strongly and coarsely punctured, the punctures 
extremely dense in middle ; sides of face with conspicuous white hair ; 
ocelli placed in a curved line, far apart; scape black, with base and 
apex bright ferruginous ; flagellum very short, chestnut red, blackened 
above; thorax very broad, circular seen from above; mesothorax 
gibbous in front, polished, with sparse shallow punctures, a strong 
median groove on anterior half; scutellum dullish, with minute 
punctures ; metathorax with much pure white hair, thin on disc 
posteriorly, the basal area white-tomentose, contrasting with the 
shining bare post-scutellum ; tegule dark reddish; wings hyaline, 
nervures and stigma dark brown; stigma small but well-formed, its 
lower side convex ; marginal cell pointed apically, the tip away from 
costa and briefly appendiculate ; two sub-marginal cells, of about 
equal size, the second contracted one-half to marginal; basal nervure 
falling some distance short of transversomedial ; first recurrent nervure 
joining second sub-marginal cell far from base, the second joining near 
to apex; hind tibie greatly broadened at end, their basitarsi very 
broad, sub-quadrate, both carrying on outer side a very coarse 
abundant pale scopa; the inner face of the tibiz is finely tomentose, 
but the narrow anterior face is bare and shining, and the apex appears 
as if prolonged into a large thorn-like spur ; abdomen polished and 
impunctate, without hair-bands; apical half of venter with coarse 
reddish hair, forming stiff brush-like apical fringes on apices of second 
and following segments. The mouth parts cannot be seen ; Mr. Barker 
notes that the tongue is short. The compound microscope shows that 
the large thorn-like structure at the end of the hind tibia is actually 
the inner spur; its margin throughout (posteriorly) is beset with fine 
very closely set. spines, forming a comb. This comb is dark brown. 
The other spur is simple. Antennal joints 4 to 6 are extremely 
short, ring-like; the apical joint is about twice as long as the one 
before. The hairs of the ventral abdominal fringe are partly 
consolidated, forming curved processes recalling those on the abdomen 
of Cambarus The end of the abdomen presents a couple of black 
hairy finger-like sting-palpi.
