AXTHONOMIA^I. 197 



1. A. quadrigibbus Say, Cure. 15; ed. Lee. i, 277; Sell. Cure, iii, 334. 



Massachusetts, Illinois, Texas. Varies in size from 3 mm. (.125 inch) 

 to 5 mm. (.2 inch); the larger specimens are more robust and have the 

 elytral tubercles much more developed, and the interspaces more uneven. 

 The beak of the 9 is longer, that of the (^ shorter than the body. 



2. A. nebulosus, n. sp. 



Dark, rufous, clothed v^'ith rather coarse ochreous pubescence; beak 

 punctured, finely carinate, with two striie on each side ; head densely 

 punctured. Protliorax closely and coarsely punctured, wider than long, 

 narrowed in front, and broadly rounded on the sides, feebly constricted 

 near the tip. Scutellum densely pubescent. Elytra at base one-half wider 

 than the prothorax, oblong, striae distant, not deep, coarsely punctured, 

 interspaces feebly punctulate, shining ; pubescence condensed so as to 

 make a pattern of bands curving forwards and outwards, the spaces near 

 the bands being nearlj' glabrous. Thighs strongly toothed, the front ones 

 with a distinct acute cusp on the distal edge of the tooth ; front tibia3 

 sinuate. Antennae with the first joint of the funiculus equal to the three 

 following ; second equal to the two following united. Length 4 mm. ; 

 .15 inch. 



Illinois and Missouri ; three specimens. The pattern of the elytra is 

 somewhat complex, and varies with denudation, but the other characters 

 are quite sufficient to enable the species to be easily recognized. 



3. A. fulvus Lee, Pr. Ac. Nat. Sc. Phila. 1858, 79. 



Texas. A large species easily recognized by the shining fulvous color, 

 very coarse punctures of tlie thorax, which has a narrow dorsal line 

 of pubescence, and the pattern of narrow lines of pubescence behind the 

 middle of the elytra. The strife are scarcely impressed, distant and very 

 coarsely punctured. The antennae are as in the preceding, but the teeth 

 of the front thighs are longer and separate. 



4. A. gularis, n. sp. 



Elongate, oWong, black, above with a few white hairs, head beneath, 

 and sides of abdomen with dense white scales, beak finely punctulate, very 

 obsoletely striate, head opaque, scarcely punctulate, with a small puncture 

 between the eyes. Prothorax a little wider than long, rounded on the. 

 sides, narrowed in front of the middle, broadly constricted near the tip, 

 convex strongly but not very closely punctured. Scutellum densely pubes- 

 cent. Elytra about one-fourth wider than the prothorax, oblong, very 

 dark red, with the suture blackish, striae distant, well impressed, finely 

 punctured, interspaces shining flat, nearly smooth. Antennae ferruginous 

 brown, joints as in the two preceding. Legs piceous, base of thighs, part 

 of tibiae and tarsi paler ; thighs strongly toothed, front pair with a very
