DESCRIPTION. 



This species is nearly the transcript of A. curculionoides, for which I at first mistook it, but a 

 closer inspection convinced me it was distinct. They agree in being black, glossy, and naked; in 

 having a red prothorax and elytra, the latter with several rows of punctures ; in having the head 

 and rostrum more or less punctured, with curved impressed lines on each side just above the eyes, in 

 the disk of the front ; the prothorax also in both is minutely punctured, and the cubit arched and 

 internally serrulated. They differ, however, in several respects. In A. curculionoides the head is 

 wider in proportion, the occiput black, levigated, with a central impression ; the curved lines of the 

 front not distinctly punctured ; the stalk of the antenna? rufous ; the prothorax at the base is streaked 

 with transverse linear impressions ; the scutellum is nearly black, and the interstices of the rows of 

 punctures of the elytra are irregularly punctured. In A. similis the hinder part of the head which 

 is punctured and wrinkled, and scutellum are rufous, a transverse impression divides the occiput from 

 the front ; the curved lines are distinctly punctured ; in the front between the eyes is a wide chan- 

 nel ; the antenna? are piceous; the prothorax is not streaked at the base: and the elytra between 

 the rows of punctures are levigated.
