34 LE CONTE.— LONGICORN COLEOPTERA 



New York and Lake Superior. The thorax and base of the elytra are sometimes 

 rufous. 



7. P. LEPiDUs. — Elongatus, niger, cinereo-pubescens, thorace Isete rufo nitido convexo, rotundato, vage 

 punctato; elytris subrugose-punctatis; antennis elongatis ; femoribus posticis, gradatim paulo clavatis. 

 Long. -47. 



One specimen from Pic river, on the north side of Lake Superior. I should have 

 considered this as the true Call, collar e, Kirby, were it not for the absence of the 

 lateral thoracic protuberance. The last joint of the antennae is constricted near the 

 apex, so as to have very much the appearance of a twelfth joint. 



CALLIDIUM, Fair. 



Oculi profunde emarginati. 

 Palpi subsequales, longiusculi. 

 Labium integrum. 

 CoxcB anticsB contiguae. 

 Mesosternum subtriangulare. 



This genus, as restricted by me, appears to be quite limited.

 rugose-punctatis, 9 thorace non latioribus. Long. -^ — 57. 



Nm. Ent. Mag., 5, 393. 



The male has the thorax wider than the elytra, the sides are thickly granulate and 

 separated from the medial smoother portion by a well defined line, having a sharp 

 ano-le directed outwardly ; the antennse are longer than the body, and much thicker 

 at the base ; the club of the femora is larger than in the female.

 thorace latioribus rugose punctatis. Long. •52.

New York, rarer than the preceding : I only possess females, and know not if the 

 thorax of the male is dilated. Both of these species are distinct from the Call.
