appearance from those of the preceding group. The head, 

 mstead of being small is rather large and very coarsely 

 punctate, the prothorax being slightly elongate and rather 

 strongly narrowed from apex to base; the elytra are equal 

 in length to the pronotum in the male and slightly shorter 

 in the female, with the sides strongly divergent posteriorly, 

 having the surface depressed and very coarsely punctate. 



9—0. CUneicollis n.sp. — Rather slender; head aud abdomen piceous-black; 

 elytra dark blackish-castaueous; pronotum dark rufo-fuscous; legs brown- 

 ish-piceous, tibias slightly paler, tarsi still paler; antenn?e and under surface 

 anteriorly dark rufo-fuscous, the former much paler toward the base and 

 apex; abdomen black, with the extreme apices of the segments paler; head 

 and pronotum nearly glabrous, elytra and abdomen finely and rather densely 

 pubescent; integuments polished. Head very slightly longer than wide; 

 sides parallel and slightly arcuate; base truncate, feebly sinuate in the 

 middle, angles rather broadly rounded; eyes very small, at three times their 

 length from the base; surface rather depressed, coarsely aud rather sparsely 

 punctate, with a very narrow median impunctate line; epistoma rather 

 strongly produced, sides convergent to the apex aud feebly sinuate; apex 

 truncate; antennal tuberculations small and rather prominent; between 

 them there are two small, oblique, impressed fove^e, each having a small 

 setigerous puncture posteriorly; antennaa rather short, scarcely as long as the 

 head and prothorax together; basal joint slightly longer than the next two 

 together, second more robust but scarcely shorter than the third. Prothorax 

 scarcely narrower than the head; sides distintly convergent from apex to 

 base and slightly arcuate; base broadly and feebly arcuate; apex with the 

 sides very stronglj' convergent to the neck, which is one-third as wide as 

 the disk aud broadly and feebly emarginate; anterior angles obtuse and 

 rather broadly rounded, basal equally so; disk transversely and rather 

 strongly convex, slightly longer than wide, rather finely and moderately 

 densely punctate, with a narrow, entire, impunctate median line. Eiijtra at 

 base slightly narrower than the pronotum; sides rather strongly divergent 

 posteriorly and feebly arcaate; together broadly and feebly sinuate at the 

 apex; disk depressed, very slightly longer than wide, as long as the prono- 

 tum, very coarsely, sub-asperately and rather densely punctate. Abdomen 

 at base very slightly narrower than "the elytra; sides very feebly divergent 

 posteriorly and distinctly arcuate; surface minutely, feebly, densely, sub- 

 asperately and irregularly punc'ate. Legs very slender; first joint of the 

 posterior tarsi fully as long as the next two together. Length 2.4-2.6 mm.

The elytra are, except near the apex, narrowly impressed 

 along the slightly elevated suture. The type is a male, the
