November, 1844. J 149 



feet : thorax narrowed before, witii the sides finely margined ; scabrous, with the 

 dorsal line faintly impressed, most distinct and dilated in front of the scutel ; 

 color darker than the elytra, sometimes with the margins darkest: scutellum 

 punctured, with a longitudinal, indented medial line: elytra punctate-stnate, 

 with the striae fine anu profound, the interstices narrow, convex, punctured, and 

 somewhat rough with transverse ruim: 1 : beneath finely and densely rugosely punc- 

 tured : feet strongly compressed dull rutous, sometimes the femora blackish- 

 brown. I have met with a description of this species. 



Lissomus, Dalman. 



L. nitidus. Black, glossy, immaculate; base of the antenna?, and tarsi, 

 dusky rufous. 



Elater nitidus, Melsh. Catal. 



Size and form entirely of Elater geminahis, Say. 



Black, shining, spotless : head sparsely and minutely punctured; antennas 

 black, with the basal joint rufo-piceous : thorax wider at base than at apex, with 

 the sides almost rectilinear; minutely punctured, punctures almost confluent 

 on the posterior margin: scutel triangular, black, impunctured, an impressed 

 longitudinal line in the middle : elytra with sparse, very minute but deeply im- 

 pressed punctures: beneath black, minutely punctured; tibiae dark rufous. Al- 

 though this species is destitute of the elytral spots, and less and differently punc- 

 tured than E. geminatus, Say, it may nevertheless be only a variety of that 

 species.

 long, 1 1. wide. Pennsylvania. 



Dark rufous, yellow pubescent, finely shagreened : head and thorax darker 

 than the elytra; antenna? nearly half the length of the body, subfiliform, with 

 the basal joint as long as the head, and not much thicker than the other joints,, 

 arcuated, obliquely truncate at tip, second joint very small, third longer than 

 the fourth, which is equal in length to the fifth, terminal joint cy lindric, longest : 

 thorax with the medial line indistinct; two obsolete obtuse impressions in front

 base, rounded at tip, where it is indented; elytra punctate-striate, the interstices
