LIXUS F. Schonh. 



1. L. MARGINATUS. — Black, covered with minute cinereous 

 hairs ; thorax impressed ; elytra, region of the scutel and middle 

 of the base indented. 



Inhabits United States. 



Body black, covered with short, minute, robust recurved hairs, 

 punctured ; antennae rufous, club dusky ; thorax a little convex 

 each side, behind the middle of the side rectilinear, a little con- 

 tracted before, with an indented line above, more profound near 

 the base ; with dilated, confluent, slightly impressed punctures 

 not deeply sinuated at base, with regular series of punctures : 

 elytra region of the scutel indented subacute : abdomen dull 

 fulvous behind. 



Length from the origin of the rostrum nearly seven-twentieths 

 of an inch. 



The hair detains a ferruginous powder. It is found on the

 same name for a very different and large species of S. America 

 from Sahlberg. [ 14"|
