DESCRIPTION'S OF NEW SPECIES. 1.1 



those of Drijala Muls. (Col. France, Barbipalpes, 58,) bul the 

 prothorax is not bifoveate at base, and the eyea are less emargi- 

 nate. The genus Dryala has qoI been adopted, because the type 

 of it, Hdllomenus fuscus, on examination by Schaum, Redten- 

 bacher, and DuVal, was found to have the anterior coxae separated 

 by the prosternum, as in the other species <>f Hallomenue. The 

 anterior coxae, in the two species described below, are prominent, 

 conical, and contiguous, their cavities have a very minute ex- 

 ternal fissure, and the lateral sutures of the prosternum are 

 obliterated, in which respect, it agrees with the genera of the tribe 

 Seraptiini. The characters are therefore anomalous, and 1 am 

 not certain that I have assigned to the genus the best position. 



In the Classification of North American Coleoptcra I incor- 

 rectly referred these two species to Trohnnma, a European genus 

 allied to Scraptia, and like it having the head strongly constricted 

 behind the eyes forming a small neck, which is received into the 

 prothorax.

Middle and Western States. Differa from the preceding by the 

 less convex and more densely punctured thorax, and the less 



shining lustre, as well as by tin- uniform color. In the male the 

 posterior margin of the 2d, 3d, and 4th ventral segment 

 membranous.
