A. variegatus n. sp. Oblong, moderately shining, piceous, varying to rufous. Rostrum shining, coarsely and irregularly punctured, at base not foveate. Thorax of nearly oblong oval form, longer than wide, subtruncate at base which is narrower than the thorax at middle, surface moderately convex, with coarse punctures finer at the sides, rather unevenly disposed, vestiture arranged as in the preceding species. Elytra oblong oval, sides moderately arcuate, disc with rows of coarse punctures becoming rapidly finer towards the apex where the strne become more evident; vestiture arranged as in the preceding species but scarcely scalelike, the surface covered by the pubescence rufous, the naked parts black or piceous. Body beneath black, shining, coarsely and sparsely punctured. Length .14-.18 inch: 3.5-4.5 mm. The elytra are never in this species as in the preceding, totally black, there being in all the specimens an oblique humeral stripe and the sub- apical band rufous, these rufous spaces may extend themselves so that the black almost entirely disappears excepting in a small triangular lateral space and the extreme tip. The vestiture is hairy rather than scale-like. Occurs from Illinois to and throughout the Gulf States.
