the lower lobes extended close to the uiandibular edge of the geuae ; 

 mandibles oblique, straight at base, turned in at right angles at 

 the apex. Antennae of cj" about one-third to tmce longer than 

 the body ; first joint stout, asperate, its apex with sharp upper 

 edge and acutely produced anterior angle or spine ; third to tifth 

 thickened, asperate, the third shorter than the fourth or fifth ; 

 sixth to tenth subequal, each much shorter than the fifth ; antenna; 

 of 2 a little longer than the body, joints third to fiffh less 

 thickened and less asperate. Prothorax slightly convex above, 

 rounded at the sides, base with rounded lobe in the middle. 

 Elytra long, more or less narrowed backwards from the base, 

 rounded at the apex. Legs long, the front pair shorter than the 

 others ; femora f usiform-clavate, compressed, pedunculate at base ; 

 tibiae compressed. Front cox^e separated, their acetabula strongly 

 angulate outwards. Mesosternum moderately broad, narrowed 

 posteriorly and truncate at the end. 



The pupae of one species at least, and probably of all the species, 

 of this genus are enclosed in calcareous cocoons of a texture 

 similar but somewhat longer and narrower in form than those 

 which enclose the pupse in the genus Ploccderus.
