curved at the end, acutely cleft internally before the tip, 

 which is very sharp, the inner lobe truncate. The pronotum 

 has a few large punctures in the middle and finer, more numerous, 

 ones at the sides. The el>i:ra show rather faint, finely ])unc- 

 tured, striae. Both jjunctures and stricTe disap])car in larger 

 examples, the head and prothorax are cxce])ti()nally narrow 

 and the mandibles long and slender. In large examples, 

 such as the type of atkinsoni Wat., the mandibles are perfectly 

 straight for f of tlieir length, the truncate inner lobe has three 

 minute cusps at the end and the shari:»-pointed outer lobe 

 bears three or four blunt teeth beneath. 



$. Unknown. 



Herr Nagel has described a specimen of unknown origin 

 which he considers to be a female of this si^ecies but, until 

 adequate grounds exist for associating the two sexes, it will 

 be safer to regard the female as yet unknown.

Bright yellow above, with the antenna^ legs (except the 

 femora in part) and lower surface darker and the edges of the 

 mandibles, head, thorax and elytra, a V-shaped mark upon 

 the head and the middle line and a small latei'al spot u])on the 

 pronotum black or very dark brown. The male opaque 

 above and the female very glossy. The three club-joints of 

 the antenna moderately long and the seventh joint shar])ly 

 produced. The prosternum compressed and i)rominent behind, 

 but rounded and not pointed. 



?. Very shining above, oval and convex. The head is very 

 coarsely punctured. The pronotum is very coarsely and 

 closely punctured at the sides and sparsely and finely elsewhere. 

 The front angles are blunt, the sides strongly rounded, without 

 distinct lateral or basal angles. The elytra are rather strongly 

 j)un{^tured and fairly closely, excei)t u])on the imier anterior 

 part. The apices are very coarsely and densely pitted. The
