[LeConte. 



small acute cusp beyond the base of the tooth, and separate from it. 

 Length 3.5 mm.; .15 inch. 



One specimen, Middle States. Resembles in form and appearance A. 

 suturalis, but is much larger, ajid the antennae and front thighs are quite 

 difierent. 



5. A. profundus, n. sp. 



■ Ovate, ferruginous, not shining, thinly and very finely pubescent; beak 

 punctured and striate, head sparsely, distinctly punctured, with an im- 

 pressed frontal line. Prothorax as long as wide, sides nearly straight 

 behind, then rounded and narrowed in front of the middle, broadly con- 

 stricted near the tip, convex, coarsely and tolerably densely punctured. 

 Elytra with deep and wide punctured striae, interspaces convex, finely 

 rugose and punctulate. Antennae as in the preceding species, with the 

 second joint of the funiculus as long as the two following. Thighs acutely 

 toothed, the front pair without accessory cusp. Length 3 mm. ; .12 inch. 



Illinois, two specimens. Larger and more robust than A. sycophanta, 

 and easily known by the deep elytral striae.

Oblong, ovate, black, thinly pubescent above, clothed with white scales 

 on the prothorax and beneath ; beak long, slender, shining, sparsely punc- 

 tured; head punctured, frontal line long and fine. Prothorax wider than 

 long, narrowed in front from the base, sides broadly rounded, feebly con- 

 stricted near the tip, closely punctured, punctures bearing white scales, 

 which become larger and less sparse towards the sides. Scutellum white, 

 pubescent. Elytra one third wider than the prothorax at the base, con- 

 vex, striae strongly impressed, punctured, interspaces slightly convex, 

 rather shining, feebly rugulose. Antennae piceous, scape and base of 

 funiculus paler, second joint of latter equal to third and fourth united. 

 Thighs armed with a small acute tooth, tibiae and tarsi piceous. Length 

 4.5 mm.; .175 inch.

One specimen found with the preceding. An oblong species, resembling 

 A. suturalis in form and size, with the beak punctured and striate, the 

 head punctured, the frontal line long ; the prothorax is a little longer than 

 wide, very coarsely and densely punctured ; the elytral striae punctured, 

 distant, not much impressed, the interspaces flat, nearly smooth. The 

 antennae are testaceous with piceous club, second joint of funiculus equal 

 to third and fourth united. Legs slender, thighs very feebly clavate, 

 armed with a very small acute tooth, almost obsolete on the hind pair ; 

 tibiae nearly straight. Body thinly pubescent, with some intermixed scales 

 towards the sides and on the under surface.
