tennae and tli(3 nearly impunctate elj'^tra separates this species 

 from its allies.

 antennae (^tlie hasal and apical joints excepted) black, thorax 

 transverse , impunctate , elytra extremely minutely punctured , 

 a transverse l)and at the base and anotlier below the middle , 

 black. 



Length ^ lines. 



Head impunctate , frontal tui>ercles nearly obsolete , clypeus 

 broad and convex , narroweil between the antennae , palpi in- 

 crassate, Havous, antennae extending to the middle of the elytra, 

 black , the basal four joints fulvous , the apical one yellowish- 

 white, all the joints rather robust, the third and fourth equal, 

 thorax three times as broad as long, the sides straight, the an- 

 terior angles broadly oljlicpie, posterior margin slightly sinuate 

 at each side, the surface entirely impunctate, with an oljlique 

 groove near the posterior angles, elytra not perceptibly punc- 

 tured, flavous, tlie base with a narrow transverse black band,

Hab. Si-Rambé. 



A single specimen of this species, which differs in the pattern 

 of the elytra from any of its allies is contained in this collection, 

 the general slape is broadly sub(|uadrate and the insect resembles 

 in that respect a species of Chnjsoniela, the posterior femora are 

 strongly incrassa te.
