They agree in being black, glossy, and naked ; in having a red prothorax 

 and elytra, the latter with several rows ot" punctures ; in having the head 

 and rostrum more or less punctured, with curved impressed lines on ench 

 side just above the eyes, in the disk of the front ; the [)rothora> also in 

 both is minutely punctured, and the cubit arched and internally serrulated. 

 They ditfer, however, in several respects. In .-7. curculionoides the head 

 is wider in proportion, the occiput lilack, levigated, with a central im- 

 pression ; the curved lines of the front not distin< tly punctured ; the 

 stalk i^i the antennae rufous ; the prothorax at the !)ase is streaked 

 with transverse linear imj^ressions ; the scutellum is nearly black, and ^^\^ 

 interstices of the rows of punctures of the elytra are irregularly punctured. 

 In A. similis the hinder part of ihc 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 channel ; tlie antennae are piceous ; the 

 prothorax is not streaked at the base : and the elytra between the rows of 

 ))unctures a'v levigated. [Synonymous with A. aiuilis lUig. ; taken in 

 Canada.]

[205.] In sculpture this species for the most part agrees with A. citr- 

 . uaonoiiic^^ except that there is an impression between the eyes, and a 

 [)air on the disk of the prothorax. The whole of the body is very black, 

 except the shoulders of the elytra, wliich are covered by a large oblong 

 red spot, the anterior thighs are armed with a minute tooth : the disk of 

 the coleoptera, or elytra taken together, towards the base is de^jressed ; 

 and the scutellum is obversely triangular, the vertex of the triangle jjoint- 

 ing towards the head, [i'his and the preceding species are both de- 

 scribed and figured in Harris' Injurious Insects, pages 65 and 66 : taken 

 in Canada.]
