CERICHRESTUS. 197 



immediately behind the eyes (between them and the base of the head) 

 is a small fulvous marking which is confluent with the marking on 

 the thorax. Thorax broader than the head, but gradually com- 

 pressed in front, so that the anterior angles (which are distinct and 

 slightly prominent) are at the same distance one from the other as 

 the eyes; the sides are slightly margin ate; at the base, and ex- 

 tending transversely towards the anterior angles, is a broad depres- 

 sion : the surface is clothed throughout with a thick short black 

 pubescence ; on either side is a broad band of bright yellow or golden 

 pubescence, which extends along the whole length of the margina- 

 tion, being slightly narrowed as it approaches the basal angles. 

 Seidell um triangular, impunctatc, black. Elytra elongate, deeply 

 punctate-striate, very finely tomentose throughout ; of a dull black 

 colour ; at the shoulders is a short oblique marking of the same 

 colour as (and connected with) the lateral band of the thorax, which 

 extends, not along the margination, but between the seventh and 

 eighth striae. Antenna not so long as the body, incrassated, black ; 

 the first joint is strongly dilated at the apex, and deflected out- 

 wards ; the second short, narrower than the first, and dilated towards 

 the apex ; the third of greater length than the first, dilated towards 

 the apex, and clothed more distinctly with long black pubescence ; 

 the fourth, fifth and sixth of the same form and colour as the third, 

 and similarly pubescent, the fourth being still more broadly dilated ; 

 the terminal joints are gradually attenuate, the ninth to the eleventh 

 being of a pale testaceous colour. Legs dark fuscous ; the base of 

 the femora, and the posterior tibiae and tarsi, being pale testaceous. 



Brazil. A single specimen of this insect is in the collection of 

 Mr. Baly.
