-which are straiglit and i)aiallel to the basal angles; punctures coarse, very 

 sparse, subrugose, Avitli the usual broad inipunctate line; antennne slender, 

 one-half longer than the head, (juite distinctly incrassate toward ai)ex, the 

 tenth joint much wider than long. I'rothorax sc<arcely perceptibly narrower 

 than the head, distinctly wider than long, trapezoidal, very iianowly and sul)- 

 proniineutly rounded at apical fourth or fifth, the sides thence ol^lique and 

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

 Elytra unusually shoj-t, scarcely 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 exceedingly small and fragile species is evidenth' allied 

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

 culiarh' coarsel}' and rugosely punctured head, but maj- be readily 

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

 more clavate antennas. It is rei)resented in my cabinet by a 

 single male, having xQvy feeble sexual characters. 



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

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

 pubescence rather short, even, sparse on the head, very dense on the prouo- 

 tum and moderately dense on the elytra. Head subquadrate, slightly wider 

 than long, trans\'ersely 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 sirrface fee])ly reticulate especially toward the 

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

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

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

 fifth, the sides thence straight and obli(iue to the base, transversely arcuate at 

 apex; disk finely, deeply and very closely punctate, i'/yw largo, two-thirds 

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

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

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

 omt)phites obsolete; punctures rather fine but deep, moderately close-set. 

 Abdomen finely but not very closely i)unctate, the punctures rather strong to- 

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

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