 New Hampshire, Mr. Leonard. Capsus triftdus Say, MSS." 



The variety alluded to is a race of Capsus dislocatus Say, and not 

 of the Resthenia just described. A specimen in my collection ob- 

 tained by myself in Maryland has the circle of the front of the head 

 filled in with black, and the hemelytra are entirely black. The ab- 

 domen is blood red, with the genital region and sternum infuscated, 

 and with the rostrum fuscous, excepting only the first joint on its 

 upper side, where it is yellowish. In the fresh specimen the rostrum 

 is remotely pubescent. 



In Dr. Harris' specimen the eyes are black, the legs fuscous, a lit- 

 tle paler on the underside of femora, the coxae yellowish-white with 

 a tinge of red, at base a little infuscated, the tarsi pale beneath; the 

 posterior pair of legs are wanting, as is also the abdomen. The red 

 margin of the hemelytra is as broad as the clavus, covering the whole 

 of the cuneus except a very small part of the inner corner. The 

 black spot -on disk of pronotum is broad at base and gradually nar- 

 rowing to the head, but dilated in a transverse streak across the cal- 

 losities. This is the only specimen now present in his collection.
