Shining black above and reddish beneath, rather narrowly oval 

 and convex. The liead is moderately finely rugose and hardlv 

 visibly notched at the apex. The j^ronotwn is convex and 

 sparingly and extremely finely punctured, except at the sides, 

 where the punctures are moderately coarse. The scutellum is 

 unpunctured but lightly impressed along the middle line. The 

 elytra are very strongly punctate-striate, with the intervals smooth 

 and nearly equal, except the subsutural one, which is wide at the 

 base and contains a few irregular punctures ; the outer and apical 

 margins are closely and irregularly punctured ; there is a minute 

 membranous fringe traceable at the inner part of the apical 

 margin, which is not obhque. The liropygidium is very finely 

 punctured and the pygidlum very strongly and confluently so. 

 The body is slightly setose at the sides beneath, and the sides of 

 the metasternum are strongly punctured. 



cS . There is a slight angular indentation at the middle of the 

 front margin of the pronotum. 



Length 13-16-5 mm. ; breadth 7-8-5 mm.

Eather elongate, black, shining and strongly sculptured. The 

 head is strongly and rugosely punctured, with the front of the 

 clypeus feebly bifid and the frontal tubercle not very strong. 

 The p)rothorax has very minute scattered punctures on the disc 

 and these become rather abruptly coarse at the sides. The scu- 

 teUum is unpunctured and longitudinally impressed down the 

 middle. The elytra are very strongly striate-punctate, all the 

 interstices being unpunctured and nearly equal, except the juxta- 

 siitural strip, which is narrow. The sides and apices are strongly 

 and irregularly punctured. The apical margins are slightly 

 truncated obliquely at the inner half and continued as a
