than the third, and equal to the fourth ; 4-8 slightly diminishing in length 

 and increasing in thickness ; 9-11 forming a compressed oval club. Pro- 

 thorax with the ridge extending along the sides to the middle. Elytra 

 cylindrical, not wider than the prothorax, with striae comiwsed of 

 large punctures. Tarsi with the first joint a little longer than the second, 

 which is triangular and emarginate ; third as wide as the second, deeply 

 bilobed ; claws acutely toothed at the middle. Mentum with the lobes 

 subacute at tip, gula transversely impressed just behind the buccal fissures. 

 Pubescence tufted ; elytra with a large transverse white spot 



in front of the middle 1. cornutus. 



Pubescence short, uniform, dense, yellowish-gray 2, lividus. 



1. A. cornutus Say, Cure. 4 ; ed. Lee, i. 263 ; A. coronatus GyW. , Sch. 

 Cure, i, 141. 



Atlantic States, especially Georgia and Louisiana. Easily recognized by 

 the tufts of hair on the prothorax and elytra, and by the conspicuous com- 

 mon transverse white spot in front of the middle, which extends to the 

 sixth stria. Length 4.6-5.8 mm.; .18-. 23 inch. 



2. A. lividus n. sp. 



Elongate-cylindrical, brown, densely clothed with short depressed mud- 

 colon^d hairs, club of antennte dark. Beak entirely flat, not at allcarinate. 

 Prothorax longer than wide, slightly rounded on the sides, narrowed from 

 the middle to the apex, which is broadly rounded ; side margin extending 

 to the middle. Elytra with striae composed of distant small punctures, en- 

 tirely even and equal in width. Pygidial groove very short, not extend- 

 ing beyond the tips of the elytra. Length 4.4 mm. ; .17 inch. 



One specimen. Lake Harney, Florida ; Messrs. Hubbard and Schwarz. 

 The front coxae are less separated than in A. cornutus, but are far from 

 being approximate, as in the other genera of the tribe. I have adopted 

 the name under Avhich it appears in the catalogue of Dejean.

A fine (^ of this well-known Cuban species was found by Mr. E. A. 

 Schwarz at Enterprise, Florida, in May. The reniform eyes and legs 

 thickly clothed with erect flying hairs, as in many Cerambycid,ce, entitle it 

 fully to generic recognition ; and the prolongation of the first joint of the 

 tarsi into a long spine in the (^ is a singular cliaracter, not occurring in 

 any other member of the family. Length 9.3 mm. ; .37 inch. 



• Group II. Cratopares. 



The insects of this group, represented by only two species in our fauna, 

 diff"er from the Anthribt, chiefly by the second joint of the tarsi less dilated, 

 longer, and though deeply emarginate at tip, concealing the third joint so 

 that the articulation is not visible from above; but merely the lobes, which do
