brown, a little darker behind and on the middle of the thorax. 

 The antennae are longer than the head and thorax; the basal 

 joints (first, second, third, fourth and fifth) and the last joint are 

 ferruginous-yellow ; the seventh, eighth, ninth and tenth joints 

 blackish-brown ; first joint large, and longer than second ; second 

 thin and slender, a little longer than third ; third, fourth and fifth 

 thin and slender and very short, nearly all of equal length ; sixth 

 shorter than these, but rather broader ; seventh largest and 

 broadest of the whole ; eighth excessively minute ; ninth and 

 tenth of equal length and thickness, rather narrower than the 

 seventh, their sides more parallel than is the case in other spe- 

 cies ; eleventh of the same breadth as the two preceding. Head 

 broad, rugosely punctate; mouth broad, concolorous. Thorax 

 pale on the margins, lightly transversely strigose. Elytra more 

 decidedly transversely strigose, with the suture and a sutural 

 stria somewhat depressed, and indistinct traces of striae towards 

 the apex. Scutellum equilaterally triangular, somewhat de- 

 pressed, clothed all over with a concolorous fuscous pubescence ; 

 beneath the pubescence the surface is somewhat shining ; under 

 side and legs fuscous-brown, paler than above; tibiae slightly 

 and delicately spinous, middle tibiae slightly bent. 



This species has very much the appearance of alpinus, but the 

 structure of the antennae is different. They are longer than in 

 that species. The club also does not gradually increase in thick- 

 ness from the first joint onwards till it reaches its greatest 

 breadth at the seventh, and then taper away again, as in 

 alpinus; the club from the eighth joint to the middle of the last 

 joint is of. equal thickness, giving a somewhat monihform ap- 

 pearance to the club, from which character I have given its 

 name. In alpinus the third joint is thicker and longer than the 

 second, while here it is smaller and slenderer. In alpinus the 

 fourth, fifth, sixth and seventh joints go on increasing in thick- 

 ness, while here the third, fourth and fifth form a narrow slender 

 peduncle, all being of nearly equal size ; the sixth and eighth joints 

 here are much smaller than in alpinus. The pubescence in this 

 species is also darker and duller and more sparing than in alpinus. 



It was found at Caraccas by M. Salle, and presented to me by 

 his relative M. Chevrolat.
