NORTH AMERICAN COLEOPTERA. 285 



Hah. — North and Middle Atlantic States ; Virginia. Described 

 from four males and four females. 



Resembles rather closely hornii and msimllis in its general ap- 

 pearance, but is larger and proportionately broader than either. It 

 may be separated from the former by the produced exterior apical 

 angles of the anterior tibiae. It differs also in this respect from a.s-- 

 xi III if is, and the apices of elytra are strongly depressed and not de- 

 hiscent at suture as in that species. 



D. as^iinilis Aube. Pis. 5, 6, figs. 7, 7 dis., "a and 7&. — Size moderate, ob- 

 long oval, distinctly convex ; surface black, strongly bronzed, not deeply punc- 

 tured ; strise usually feebly marked ; lateral margins of elytra in % not sinuate, 

 apices feebly sinuate, slightly dehiscent at suture and not strongly depressed, 

 sutural angles feebly produced ; in 9 the lateral margins of the elyti-a and apices 

 more strongly sinuate and dehiscent at suture, sutural angles produced; under 

 surface black, more or less tinged with brown, very shining, middle and posterior 

 legs testaceous; anterior tibife regularly widening from base to apex ; apex trun- 

 cate, exterior apical angle rectangular, scarcely or not at all produced : femora 

 without tooth, punctures (7 ^,8 J) shallow and not closely placed. Length 

 10-11 mm. ; breadth 5.5-6 mm. 



Hah. — North, Middle and South Atlantic States; New Mexico, 

 Colorado, Minnesota, Michigan and Dakota. 



As remarked under those species, honiii and iiigrior have been 

 mixed with asmiiilw ; their more evident differences may be sum- 

 marized as follows: Anterior tilme : in honiii with, apex oblique, 

 exterior angle obtuse ; nigrior apex truncate, exterior angle acute 

 and evidently produced ; assimilis apex ti-uncate, exterior angle rect- 

 angular and scarcely or not at all produced. Sutural angles : in 

 hornii % rounded, 9 produced, and with the suture strongly dehis- 

 cent ; in nigrior Z and 9 produced, apices depressed and not de- 

 hiscent at suture; in assimilis $ and 9 produced, apices fee 6/// 

 dehiscent at suture. Set ig era as femoral punctures: in hornii few 

 ((i ^ , 7 9 )) "ot deep or closely placed ; in nigrior numerous (_9 Z , 

 10 9 ), deej) and closely placed ; in assimilis moderate (7 S , 8 9 ), 

 shallow and not closely placed. The male genitalia are entirely 

 unlike, as shown by the figures on the plate. 



n, prodnctus n. sp. Pis. 5, 6, figs. 8. 8« and 8i.— Size small, ovate, not 

 very convex; surface shining, strife faint, punctures quite evident; % lateral 

 margins of elytra not sinuate, ai)ices slightly sinuate and dehiscent at suture, 

 depressions not strongly marked, sutural angles produced ; 9 lateral and apical 

 strongly and irregularly sinuate, more dehiscent at suture, deiK-essions deeper 

 and sutural angles more sliar])ly produced ; under surface black, strongly bronzed 

 and shining, middle and posterior tibiie and tarsi and last abdominal segment
