fiftli and eighth somewiiat more convex; each interspace witli a row of 

 very short, thiclv, inconspicuous bristles. Length 4 mm. ; .16 incli. 

 One specimen, Illinois. Easily known by the strongly carinate prothorax. 



7. A. granosus, n. sp. 



Rather stout, black, densely clothed with dark brown scales. Prothorax 

 as wide as long, rounded on the sides, scarcely Avider at the middle than at 

 the base, much narrowed in front, and broadly constricted; disc densely 

 ])unctured, strongly carinate, marked Avith a short, transverse white line at 

 the middle, interrupted at the dorsal line; the parts of this transverse line 

 are nearly joined by a short, posterior dorsal Avhite line, forming a T-shaped 

 mark; there are also a few inconspicuous dots of white pubescence. Elytra 

 ovate, distinctly wider at the middle than the prothorax, truncate at base, 

 with the basal angles well defined; striiE composed of large, shallow, quad- 

 rate punctures; interspaces well detined, the alternate ones more elevated, 

 and interrupted so as to become tuberculate; the brown scales are mottled 

 with dots of pale scales, of which the most conspicuous form a narrow, ir- 

 regular, transverse band about the middle; the bristles are very short, but 

 more di>tinct than in the preceding species. Length 3.4 mm.; .13 inch. 



Florida, at Enterprise, Haulover and Indian River; Messrs. Hubbard 

 and Schwarz. 



8. A. sordidus, n . sp. 



Robust, black, clothed with a dirt colored crust concealing the sculp- 

 ture, with intermixed slender, curved bristles pointing backwards; beak 

 naked and punctured towards the tip, not carinate; front not channeled. 

 Prothorax a little wider than long, rounded on the sides, obsoletely chan- 

 neled. Elytra striate, with the interspaces slightly convex, with rows of 

 reclinate bristles. Length 2.5 mm.; .10 inch. 



Texas, Belfrage; one specimen. 



9. A. clavatus Say, Cure. 39; ed. Lee. i, 297: Boh., Sell. Cure, iv, 354. 



Enterprise, Florida; Messrs. Hubbard and Schw^arz; found also in Illi- 

 nois. This small species is thickly clothed with brown scales, and but 

 slightly varied in color; there are, however, two interrupted bands composed 

 of small white spots on the elytra; the striae are composed of large, quadrate 

 punctures; the interspaces are wide, slightly convex and furnished with 

 rows of long, clavate bristles. The prothorax is very coarsely punctured, 

 not carinate, and the bristles are a little shorter than upon the elytra. 

 Length 2.5 mm. ; .10 inch. 



The female is stouter than the male, witii the prothorax not mucli wider 

 at the middle, and the elytra much more rounded on the sides. 



I have received from Col. Motschulsky a specimen from New Orleans, 

 which seems quite similar, except that the punctures of the elytral strise 

 are so large that the interspaces become very narrow. I am disposed to be- 

 lieve that this appearance is owing to partial abrasion of the scales. If, 

 however, Avith a larger series of specimens, it should be found to bo really 

 distinct, the name A. xcabrosus Motsch, Avill be retained for it.
