720 Coleopterological Notices, VI. 



which are straight aud parallel to the basal angles; punctures coarse, very 

 sparse, suhrugose, with the usual broad impunctate line; antennae slender, 

 one-half longer than the head, quite distinctly incrassate toward apex, the 

 tenth joint much wider than long. Profhorax scarcely perceptibly narrower 

 than the head, distinctly wider than long, trapezoidal, very narrowly and sub- 

 prominently rounded at apical fourth or fifth, the sides thence oblique and 

 straight to the base; apex very broadly arcuate; disk finely, sparsely punctate. 

 Elytra unusually short, scarcelj' more than one-half longer than wide, twice 

 as wide as the prothorax, suboval, the sides parallel, evenly and rather 

 strongly arcuate; apex moderately obtuse; humeri broadly rounded to the pro- 

 thorax, moderately exposed at base; disk somewhat feebly convex, the post- 

 scutellar impression very small and feeble; omoplates obsolete; punctures fine 

 but strong, rather close-set. Abdomen minutely, obscurely punctate, more 

 distinctly and sparsely so toward base, the legs rather long, very slender. 

 Length 1.75 mm.; width 0.6 mm.

This exceeding]}- small and fragile species is evidentl}' allied 

 rather closely to nanus and other species of this group, with pe- 

 culiarly coarsely and rugosel}- punctured head, but ma}' be readily 

 known from any of them by the shorter and suboval elytra, and 

 more clavate antennae. It is represented in my cabinet by a 

 single male, having ver}' feeble sexual characters. 



44. A. obliquus n. sp. — Somewhat stout, the elytra slightly depressed, 

 shining, pale flavo-ferruginous throughout, the abdomen sometimes blackish ; 

 pubescence rather short, even, sparse on the head, veiy dense on the j)rono- 

 tum and nioderatelj^ dense on the elj'tra. ffeatJ subquadrate, slightly wider 

 than long, transversely truncate at base, very feebly impressed at the middle 

 of the basal wall ; angles somewhat broadly rounded, the tempora gradually 

 becoming straight and parallel for a short distance behind the eyes, the latter 

 rather large and convex, longer and more prominent than the tempora; punc- 

 tures very coarse and sparse, the surface feebly reticulate especially toward the 

 sides; antennae barely as long as the head and prothorax, very feeljly incras- 

 sate. Prothorax rather large, just visibh' narrower than the head, not quite as 

 long as wide, somewhat narrowly rounded but not at all angulate at apical 

 fifth, the sides thence straight and oblique to the base, transversely arcuate at 

 apex; disk finelj-, deeplj' and verj* closeh- punctate. Elytra large, two-thirds 

 longer than wide, fully twice as wide as the prothorax ; sides parallel, broadly 

 and feebly arcuate, rather obtusely rounded at apex; humeri widely and 

 transversely exposed at base; scutellar impression visible but broad and feeble; 

 omoplates obsolete; punctures rather fine but deep, moderately close-set. 

 Abdomen finely but not very closely punctate, the punctures rather strong to- 

 ward base; pubescence somewhat short and coarse, the legs moderately long, 

 very slender. Length 2.0-2.1 mm. ; width 0.75-0.8 mm.
