[LeConte, 



elytra with impressed punctured strige, interspaces nearly flat, shining, 

 sparsely punctulate. Thighs with a very small tooth, front tibiae straight, 

 scarcely sinuate on the inner margin.

 Western States, Illinois; Mr. Walsh. Breeds in galls on willow trees. 



Tliis species is easily known by the interspaces of the elytra rather flat, 

 and nearly opaque; the punctures of the prothorax are very coarse and 

 crowded. The pubescence is hairy above, but coarser and almost scale- 

 like beneath, the beak is punctured and striate; the thighs are all armed 

 with a tooth, and the front tibiae are nearly straight. The color varies, 

 but the elytra are always red, though sometimes darker near the scutellum. 

 I am disposed to believe this is A. hmmatopus Boh. Sch. Cure, vii, 2, 

 323, with the description of which it agrees in all particulars, except that 

 tlie prothorax is not "rugoso granulato," a style of sculpture very unlikely 

 to occur in the genus, but which may be a vague method of indicating the 

 very coarse deep punctures with narrow high intervals which characterize 

 this species. 



13. A. rufipennis, n. sp. 



Oblong, blackish, thinly but finely pubescent with white hair. Beak 

 striate and punctured, head sparsely punctulate, front foveate; prothorax a 

 little longer than wide, narrowed in front and broadly rounded on the 

 sides, feebly constricted as usual, surface densely and coarsely punctured, 

 though less so than in the preceding species; elytra oblong, humeri less 

 prominent than usual, and rather oblique, striae well impressed, coarsely 

 punctured, interspaces slightly convex, shining, sparsely punctulate, ferru- 

 ginous, suture darker, scutellum clothed with white hairs. Antennae and 

 legs ferruginous, thighs strongly toothed, front tibiae straight, slightly sinu- 

 ate on inner side. Length 2.3 mm., .09 inch. 



One specimen, Pennsylvania. Of the same form and size as the pre- 

 ceding, but easily known by the less coarse punctures of the pi-othorax, 

 and the smoother and shining elytral interspaces ; the humeri are less promi- 

 nent than in our other species.

Middle, Southern, and Western States. Varies in color and extent of 

 the red elytral spot, which is sometimes bright yellowish-red, and distinctly 

 limited, sometimes dark and difl'used, so that only the suture remains 

 blackish. In one specimen the surface of the elytra is dull and finely ru- 

 gose, but I suspect that this has been caused by some injury received in 

 the early stages of development, and must be regarded as an accidental 

 monstrosity, and not as a variation.
