CERAMBYCIDAE. 343 



are parallel and cylindrical, rounded at tip. The front coxae are 

 angulated externally and closed behind. The mesosternum is 

 protuberant and perpendicular in front ; the middle coxa3 are 

 angulated, but scarcely open externally. The 5th ventral segment 

 (in 9 ) is as long as the three preceding united, and truncate at 

 tip. The legs are short, equal, the thighs not clavate, the middle 

 tibiffi sulcate externally, with a slight protuberance ; 1st joint of 

 hind tarsi not longer than the 2d ; claws divaricate. 



The antennae ( 9 ) are two-thirds the length of the body, and 

 pilose, the scape rather stout, scarcely clavate, joints 4-11 gradu- 

 ally, but rapidly decreasing in length. 



This insect is remarkable for being covered with very dense 

 brown pubescence, with lines and crests of very long, fine whitish 

 hairs looking like mould. Beneath it is very prettily variegated 

 with darker spots each surrounded with a white line. Length 15 

 mm. The only specimen I have seen was sent from Texas to 

 Mr. A. S. Fuller, and given me by Dr. Horn. 



Tribe XL OIVCIDERIiVI. 



With this tribe commences a series in which the front coxal 

 cavities are angulated externally and closed behind, the middle 

 ones open externally, and the claws moderately divergent. The 

 antennae in the present tribe are longer than the body in the $ , 

 about as long as the body in the 9 , and the scape is stouter, 

 subcylindrical, nearly as long as the 3d joint, and has no apical 

 cicatrix. The front is very large, quadrate, vertical, and flat, the 

 support of the labrum coriaceous, the mouth large, the palpi 

 slender, last joint cylindrical, obtusely pointed. The prosternum 

 is very short in front of the coxae, prominent between them, 

 declivous before and behind ; mesosternum truncate between the 

 coxae. Yentral segments equal in length, 5th broadly emarginate 

 in both sexes, and impressed in the 9 . Legs rather stout, equal ; 

 thighs moderately clavate, middle tibiae with a tubercle on the 

 outer margin, hind tarsi with the 1st joint broad, not longer than 

 the 2d, last joint as long as the others united, claws approximate, 

 slightly divergent. 



Oncideres cingulatus is remarkable for placing the eggs in 

 small branches of trees, especially hickory, and then cutting 

 through the bark below, so as to kill the branch, which is after-
