54 AMERICAN COLEOPTERA. 



Oue of our most easily recognizable species, possessing several 

 well-marked characters. 



It is known to me from New Hampshire, Massachusetts, Rhode 

 Island, New York, Pennsylvania, Maryland and Virginia. 



40. A, crassispiiia Lee. — Broadly oval, moderately convex. J^neous or 

 nigro-seneous, shining; surface finely alutaceous, more strongly in the females. 

 Head slightly narrower than the thorax at apex ; antennje not carinate, shorter 

 than the head and thorax, piceous, the three basal joints rufous; palpi piceous. 

 Prothorax subquadrate, impunctate, more than one-half wider than long, nar- 

 rowed from base to apex; apex slightly emarginate; sides slightly arcuate, more 

 strongly anteriorly, margin narrowly reflexed, the posterior setigerous puncture 

 large, distant from the side margin ; transverse impressions obsolete or nearly 

 so; median line fine, abbreviated at each end ; basal impi-essions nearly obsolete, 

 the inner sometimes feebly distinct; base feebly bisinuous; hind angles not 

 prominent, subrectanguiar, slightly rounded, not carinate. Elytra slightly wider 

 than the thorax, striate; stride entire, impunctate, the scutellar stria without 

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

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

 prosteruum broad, truncate at tip. Legs rufopiceous, the femora darker; all the 

 femora with two setigerous punctures along the inner margin ; anterioi- tibia> 

 with the apical spur stouter than usual ; tarsi n((t grooved on the outer side. 

 Length .29-.36 inch ; 7.25-9 mm. 



In the males the hind tibise, although distinctly pubescent, are 

 somewhat less conspicuously so than is usual in the subgenus. 



From allied species it seems distinct by the characters given in 

 the table. The position of the posterior marginal setigerous punc- 

 ture is nearly as in cupreolata, while the tip of the prosternum 

 recalls that of conflata. 



It occurs from Massachusetts southward to South Carolina 

 and Alabama and westward to Lake Superior, but appears to 

 be local. 



4L A. parviceps n. sp. — Form nearly oblong, very convex. Color black, 

 .shining. Head small, slightly narrower tlian the thorax at apex, and scarcely 

 one-half as wide as the thorax at base; frontal grooves obsolete ; antennae not 

 carinate. with the three basal joints testaceous, the next four rufopiceous (the 

 others lacking in the type); palpi testaceous. Prothorax very convex, about 

 one-half wider than long, narrowed from ba.se to apex; very strongly narrowed 

 from base to apex, very strongly narrowed in front of middle; apex deeply 

 emarginate, the anterior angles prominent, rounded ; transverse and basal im- 

 pressions obsolete; median line fine, abbreviated in ficint; sides with the margin 

 narrowly reflexed, arcuate, the posterior lateral setigerous punctures large, 

 distant from the side margin ; base nearly truncate; hind angles rectangular, not 

 carinate. Elytra not wider than the thorax, parallel to behind the middle, 

 striate; striae entire, impunctate, the scutellar stria without ocellate puncture at
