when with Major Long's party. It may ho <li.«tincuished from 

 the preceding hy the striated elytra, and by tlie I'iniple edge of 

 the thorax. 



[Tnlcnown to me, perhaps a Blapslxiuig. — Lec] 



BOROS Herbst. 



B. uxicoLOR. — Blaekish-brown, punctured ; thorax not obvi- 

 ously indented behind. 



Body depressed, rather slender, blackish-brown, punctured : 

 head suboval, punctures rather large, numerous; smaller before ; 

 a dilated indentation each side anterior to the eyes : antennae but 

 little longer than the head : thorax oval, accurately rounded each 

 side, punctures numerous, rather large; no indentation : elytra 

 with irregular, numerous punctures, smaller than those of the 

 thorax, not disposed in any regular series; an obtuse indented 

 line on the outer margin, and another at the suture. 



Length nine-twentieths of an inch. 



I received this in.sect from Dr. J. F. Melsheimer, under the 

 name I have adopted. It is certainly very closely allied to B. 

 tfongnttis Herbst, but judging by the figure given by this author, 

 it is much smaller ; it is also destitute of any obvious indentation 

 on the posterior pai't of the thorax. 



[On comparison I find the sides of the thorax to be a little 

 more rounded than in the European specimens. — Lec]

 behind ; brown, covered with veiy numerous, bright sericeous 

 hairs : antenna; and palpi rufous : thorax but little undulated on 

 the posterior edge : elytra with slender, punctured striae : beneath 

 color of the antennae. 



Length one-fifth of an inch. 



At first view, this roight be mistaken for the E. bkolor Fabr.
