56 AMERICAN COLEOPTKRA. 



43. A. COiiflaf a Lee. — Form broadly oval, moderately convex. Color black, 

 scarcely seneoiis, surface finely alutaceotis, more coarsely in tlie females. Head 

 slightly narrower than the thorax at apex; antennae shorter than the head and 

 thorax, not carinate, piceous, the three basal joints rufous; palpi rufopiceous. 

 Prothorax subquadrate, about one-half wider than long, very distinctly wider at 

 base than apex, impunctured ; apex emarginate ; sides rounded in front, sub- 

 parallel behind the middle, the margin narrowly reflexed, the posterior lateral 

 setigerous puncture about equidistant from the side and basal margins; base 

 bisinuous; hind angles rectangular, not carinate. Elytra slightly wider than 

 the thorax, striate; striae entire, impunctate, the scutellar stria without ocellate 

 puncture at base, the eighth with the row of ocellate punctures rather broadly 

 interrupted at middle ; intervals nearly flat. Body beneath black, impunctate; 

 prosternum subtruncate or very broadly rounded at ti]i. Legs black; all the 

 femora with two setigerous punctures along the inner margin ; middle and pos- 

 terior tarsi with the basal joint at most very feebly grooved on the outer side. 

 Length .35-.42 inch ; 8.75-10.5 mm. 



Easily known from A. cupreolata by its larger size and less con- 

 vex form, as well as by tlie position of the posterior puncture of 

 the side margin of the thorax and the color of the legs. 



It occurs along the Pacific Coast from California to British 

 Columbia, and I have seen one specimen from Utah. 



44. A. brunnipes Motsch. — Form elongate, convex. Nigro-a>neous, very 

 finely alutaceous. Head scarcely narrower than the thorax at apex; antenna" 

 shorter than the head and thorax, not carinate, piceous, the first three joints 

 paler; palpi dark rufous. Prothorax subquadrate, slightly wider than long, 

 wider at base than apex, impunctate; sides subparallel behind, rounded from 

 about the middle to apex, the margin narrowly reflexed ; apex very slightlj' 

 emarginate; transverse and basal impressions obsolete; median line very fine; 

 base truncate; hind angles rectangular, not carinate, the posterior lateral seta in 

 the hind angle. Elytra very slightly wider than the thorax, striate; striae im- 

 punctate, entire, the scutellar stria without ocellate puncture at base, the eighth 

 with the row of ocellate punctures very broadly interrupted at middle; intervals 

 flat. Body beneath dark piceous, impunctate. Front and middle legs daik 

 rufous (the hind pair wanting in the specimen studied) ; middle femora with two 

 setigerous punctures along the inner margin; terminal spur of anterior tibise 

 somewhat stouter than usual. Length .32 inch ; 8 mm. 



The above description is from a mutillated female in the LeConte 

 collection. It is from California, and is the only example known 

 to me. The anal segment is bisetose each side. 



45. A. pi'olcnNa. Putz. — Oblong-oval, moderately convex. Black sometimes 

 tinged with blue or rarely slightly aeneous, usually dull, the surface alutaceous, 

 more strongly so in the females, at most feebly shining in the males. Head 

 slightly narrower than the thorax at apex ; antennae shorter than the head and 

 thorax, black, the two basal joints rufous, the second usually somewhat darker, 

 joints 2-3 strongly carinate; palpi black. Prothorax subquadrate, more than
