 the front margin, which is nearly straight. The jn-othorax is 

 coriaceous, with fine punctures at the sides, the lateral margins 

 feebly angulated in the middle and the base strongly excised 

 before the sctitellum, which is unpunctured. The eh/tra are very 

 smooth, with scarcely perceptible traces of sutural and discoidal 

 stria?, but rather strongly rugulose near the margins posteriorly. 

 The pygidmm is rugulose except in the middle. The sternal 

 process is narrow, parallel-sided, broadly rounded at the end, and 

 about as long as broad measured from the meso-metasternal 

 suture. The metastemum is not distinctly punctured, and the 

 (thdomen is veiy smooth except at the sides, which are sliglitly 

 strigose.

 in the middle. The prothorax is finely coriaceous, not visibly 

 punctured, rather convex and very narrow in front, with the sides 

 feebly angulated in the middle, tlie hind angles rounded and the

 metastemum is unpunctured and the abdomen feebly strigose at 

 the sides.
