the preceding in which the red is diffused over the elytra; but smaller and 

 more robust, with the beak more slender, and the funicle of the anten- 

 nae with the outer joints more rounded; I can find no other differences 

 worth mentioning, and it will very probably be found to be not distinct. 



16. A. sulcifrons, n. sp. 



Black, with rather dull lustre, thinly pubescent above, more densely be- 

 neath. Beak strongly punctured, striate at base, head sparsely punctulate, 

 with a deeply marked frontal stria. Prothorax wider than long, gradually 

 narrowed from the base, feebly rounded on the sides, deeply and densely 

 punctured. Elytra one-third wider than the prothorax, slightly ovate, 

 striae deep, coarsely punctured, interspaces convex, nearly smooth ; behind 

 the middle are two series of small spots of pubescence, as in well pre- 

 served specimens of the preceding three species. Antennae piceo-testa- 

 ceous; thighs scarcely clavate, with a very small tooth scarcely visible on 

 the middle and hind pair. Length 1.6 mm.; .065 inch. 



One specimen, Georgia. Also related to the two preceding, but readily 

 known by the entirely black color, and sulcate front. 



17. A. flavicornis Boh., Sch. Cure, vii, 2, 231. 



Maryland to Texas. The beak is sparsely punctured, finely striate, head 

 nearly smooth, front channeled, prothorax moderately densely punctured, 

 and elytral striae fine, distant, and finely punctured. The pubescence is 

 white, coarse, and thinly distributed, a little more dense beneath. The 

 antennae are yellow -testaceous, and the tarsi piceous. All the thighs armed 

 with a small acute tooth. The scutellum and a small intra-hurneral spot 

 are densely pubescent. 



18. A. morulus, n. sp. 



California, San Mateo and Gilroy; Mr. Crotch. 



A small black species of the same size and general form (2.2 mm.; .09 

 inch), as the preceding, but with the beak longer and more punctured, the 

 head distinctly punctured, the frontal stria shorter. The prothorax is 

 equally strongly punctured, but more rounded on the sides. The elytral 

 striae are well impressed, strongly and closely punctured, and the inter- 

 spaces flat and rugose. The pubescence is very fine and sparse, a little 

 more distinct beneath. The antennae are dark-testaceous with the club 

 piceous; the thighs are scarcely clavate, and hardly perceptibly toothed. 



19. A. nigrinus Boh., Sch. Cure, vii, 2, 230. 



Georgia and Louisiana; three specimens. Of the same size and general 

 form, and as finely pubescent as the last species. The prothorax is very 

 coarsely punctured, and the elytral striae are less impressed, but more 

 coarsely punctured, and the interspaces less flat, and nearly smooth. The 

 antennae are nearly black, the thighs are armed with a very minute tooth, 

 more distinct on the front pair. 



20. A. corvulus^ n. sp. 



Black, slightly pruinose with sparse white pubescence. Beak punctured 

 and feebly striate, head opaque, with a small frontal fovea. Prothorax
