A suboblong black species, with a median carina on the 

 pronotum as in serricollis and pygidia&is, to which it is allied, 

 but from both of which it differs in many respects. Seen 

 obliquely from behind the middle portion of the basal 

 depression appears to have some coarse punctures, the parts 

 beyond the membranes appear to be almost circular and 

 highly polished. 



Chlamydopsis compressipes, n. sp. 



Castaneous. 



Head immersed in prothorax ; face with shallow reticu- 

 late punctures. Antennae rather short; scape curved, its 

 apical half thick, with punctures as on face; funicle short, 

 apparently six- jointed; club subelliptic. Prothorax strongly 

 transverse, front margin slightly elevated behind head, thence 

 to sides strongly elevated and lightly curved, sides feebly 

 elevated and slightly curved, middle gently elevated and 

 with a short feeble transverse carina ; with shallow, reticulate 

 punctures. Elytra slightly but distinctly wider than long, 

 suddenly much wider than prothorax; epaulettes raised and 

 rounded, with punctures as on pronotum, close to the inner 

 side of each epaulette a narrow ridge conspicuously elevated 

 above it, a small upright fascicle between its hind end and 

 the margin; basal depression wide, deep, and semidouble, 

 its ends partly concealed in places; with elongate, subreticu- 

 late punctures in middle, changing to simple striae; outer 

 walls with numerous striae, all converging to a rather large 

 but shallow fovea. Most of metasterrmm and of abdomen 

 shining and with small punctures, rest of under-surface, 

 pygidium, and propygidium opaque and with punctures as 

 on pronotum. Legs long, thin, and compressed. Length, 

 2'25 mm.

At first glance fairly close to epiplenralis, with which it 

 would be associated in my table of the genus, but readily 

 distinguished therefrom by the epaulettes and tibiae ; on the 

 present species each epaulette is conspicuously raised, and at 

 its greatest elevation is not disconnected with the part behind 

 it, and its side has a round fovea not connected with the 

 basal depression, although in line with it; the inner process 

 near each epaulette is also terminated by a narrow ridge 

 elevated above it; the tibiae have the outer outline gently 

 rounded off, instead of angulate in middle; pallida, with 

 somewhat similar tibiae, has very different epaulettes. The 

 elytra are distinctly wider than long, and at the base are
