punctate, alutaceous. Legs somewhat short and stout. Length 

 3.5 mm.; width 1.1 mm. 



Regions near the Great Lakes. The male of this very isolated 

 species has the posterior trochanters simple, the hind tibiae in- 

 crassate and feebl}', inwardly arcuate, the fifth ventral distinctly 

 longer than the fourth, ver3^ broadly arcuato-truncate throughout 

 the width, the genital segment black, corneous, very broadlj' 

 arcuato-truncate, polished and with a large rounded median im- 

 pression. 



20. A. moiiticola ii. sp. — Katlier stout, shining, black throughout, the 

 tibia? antl tarsi pale; pubescence coarse, cinereous, moderately short, abundant 

 and conspicuous. Head large, subquadrate, moderately convex, broadly arcu- 

 ato-truncate and broadh', feebly impressed at base, the angles ])roadly rounded 

 into the tempora, which become parallel behind the eyes, the latter prominent, 

 rather large, at one-half more than their own length from the base; surface 

 somewhat finely but strongly, moderately closely punctured, Avith a narrow 

 entire impunctate line; antennaj not quite as long as the liead and prothorax, 

 very feebly incrassate, the tenth joint not distinctly elongate. Prothorax 

 rather large, slightly narrower than the head, as wide as long, rounded on the 

 sides anteriorly, obliquely naiTowed thence to the basal margin, which is de- 

 fined by a fine impressed line and dilated somewhat at the sides; punctures 

 somewhat coarse deep and close. Elytra three-fourths longer than wide, per- 

 ceptibly more than twice as Avide as the jirothorax, slightly wider at the mid- 

 dle than at base; apex rather broadly rounded; scutellar impression feeble; 

 omoplates obsolete ; punctures strong and somewhat close but not very coarse, 

 ^ftdomew shining, finely, closely punctate, the pubescence short, fine and rather 

 dense. Legs somewhat long and slender. Length 3. '2 mm.; width 1.05 mm. 



Wyoming (Laramie). 



The four specimens before me do not exhibit any variation, and 

 their sex is not apparent. This species is not comparable very 

 closely with any other known to me. 



21. A. ceplialotes n. sp. — Kather narrow and subdepressed, polished, 

 black, the legs piceo-rufous; pubescence moderately long, cinereous, somewhat 

 dense and distinct. Head large, convex, subcjuadrate, slightly transverse, 

 broadly truncate and feebly impressed at base, the angles rounded, the tem- 

 pora becoming parallel at a consideraljle distance behind the eyes, the latter 

 moderate in size; surface rather coarsely and densely punctate, with a narrow 

 and entire impunctate line; antenna; missing in the type, pale at base. Pro- 

 thorax rather small, not more than tliree-fourths as wide as the head, not longer 

 than wide, widest and somewhat narrowly rounded near apical fourth, the 

 sides thence rather strongly and somewhat arcuately convergent to the feeble 

 ante-basal constriction; basal margin defined by a fine impressed line; punc- 

 tures rather fine but strong, not dense, the surface moderately convex and
