Antenna' elongate and slender, almost g-eniculate, not 

 thickened towards the extremity; 1st joint elongate, as 

 long as the three following together; 2nd joint rather 

 long, 3rd more slender than, but about as long as 2nd, 

 5 — 10 each a little shorter than its predecessor, 1 1th rather 

 long, slightly stouter than, and twice as long as the lOth. 

 Mandibles elongate, the left one with two teeth, of which 

 the upper one is elongate, the right one with three rather 

 large teeth. Labrum large, the middle prominent, and 

 ■with two rather long and slender teeth, and on each side 

 of these with a small obscure one. ISIaxillary palpi pale 

 yellow ; 2nd and 3rd joints elongate and slender, the 3rd 

 being about four times as long as broad. Head rather 

 large, broader than the thorax and quite as broad as the 

 elytra, the vertex rounded, the neck narrow, the eyes 

 remote fi'om the antenna3, the colour pitchy or infuscatc 

 red ; the surface rather coarsely punctured, with the usual 

 Snnius pmictuation. Thorax a good deal narrower than 

 the elytra, rather longer than broad ; the greatest width in 

 front of the middle, thence abruptly narrowed to the front, 

 and a good deal toAvards the base ; in colour and sculpture
