H. C. FALL. 171 



antenTial groove ; ( 9 ) a- little longer and less attenuate. Antennae short, first joint 

 equal tu the next two (1), or three ( ? ), joints 6-8 transverse, the eighth 

 decidedly so, second passing the margin of the eye. Front punctate, not sulcate ; 

 eyes not very prominent. Prothorax as long as wide ; hase barely wider tlian 

 the apex ; sides feebly, evenly arcuate; apical constriction obsolete; basal sinua- 

 tion wanting; surface strongly, moderately, closely punctate; a median impunc- 

 tate line, which is incomplete and imperfectly defined ; basal fovea present. 

 Elytra narrow, nearly or quite without humeri: intervals not wide, convex. 

 Beneath deeply and rather coarsely and closely punctate; metasternum shorter 

 than the first ventral ; sternal side pieces quite densely pubescent; claws with a 

 small acute tooth. Length 1.4-2 mm. ; .056-. 08 inch. 



% . Sutural angles narrowly rounded ; first joint of middle tarsi with an 

 acute spiniform process. 



9. Sutural angles scarcely rounded ; tarsi as usual. 



Hab. — District of Columbia, New Jersey (Southern part, Lie- 

 beck), Michigan (Detroit, Schwarz), Massachusetts (Blanchard), 

 Illinois. 



In some specimens the first antennal joint is quite conspicuously 

 paler. A remarkably distinct little species by its lack of humeri, 

 short metasternum and male characters. It perhaps most closely 

 resembles temdjorme, which agrees in size and general facies, and in 

 the spined male tarsi, but differs rather widely in its moderate 

 humeri, normal metasternum, nearly simple claws and incrassate 

 middle femora of the male. Not common. 



100. .4. aciileatiiin n.sp. — Not robust, dull black; front legs often more or 

 less pallescent ; pul)escence yellowish cinereous, rather conspicuous. Beak (%) 

 not very slender, moderately curved, shorter than the head and prothorax, dull, 

 except in about the apical third, which is somewhat shining; punctuation fine 

 above, coarser at the sides; ( 9 ) ^ little more slender, slightly longer than the 

 head and thorax, more finely punctate, the punctures at the sides tending to a 

 serial arrangement, somewhat dilated at the extreme base in both sexes. First 

 joint of the antennae subequal to the two following and nearly or quite reaching 

 the eye. Front narrow, scarcely wider than the tip of the beak, with two con- 

 fluent lines of punctures: eyes not prominent. Prothorax a little wider than 

 long, usually slightly wider at base than at the middle; basal and apical con- 

 strictions distinct; sides arcuate at the middle; punctuation rather fine and 

 sparse: basal fovea evident. Elytra fully one-half longer than wide, subparallel : 

 sides feebly arcuate; humeri moderate; intervals about twice as wide as the 

 strife, more or less convex. Beneath finely, sparsely punctulate: legs rather 

 slender; claws rather feebly toothed. Length 1.6 mm. ; .06.5 inch. 



% . Sutural angles rounded ; first joint of middle tarsi with spiniform process. 

 9 . Sutural angles scarcely rounded ; tarsi not spined.
