 mentioned by Crotch, as well as the ungual tooth from the specific charac-

This species has the same form as G. varians, but differs by the irregularly 

 punctured prothorax being more strongly margined at the base. The pu- 

 bescence is partly abraded, giving a nebulous appearance, as is often the case 

 in other species. 



COI^ASPIS Fabr. 



C. arizonae Crotch, 1. c, 45. This species varies greatly in the 

 color of the elytra ; in the specimen described they are entirely red, but 

 usually they are of a dark metallic green color, with the entire border 

 red, and transverse band at the first fourth extending from the suture 

 nearly to the side border. 



L,UPERUS Oliv. 



,Ii. maculicollis. — Greenish black ; prothorax orange, shining, obsoletely 

 punctulate, finely margined, slightly rounded on the sides with a long black dorsal 

 spot and a smaller lateral one. Elytra shining blue, finely punctured, with slight 

 traces of strise. Antennse fuscous, lower joints and mouth testaceous. Length

San Diego, Cala. ; found abundantly by Mr. 0. N. Sanford. The 

 antennae are half as long as the body in both sexes ; the last ventral is 

 impressed in the male. The lateral thoracic spots are frequently reduced 

 to mere dusky clouds ; there are no discoidal impressions.
