 elongate and slender, a good deal longer than 2nd, 1 1 th

 small (in the female). Head large, a little broader than

 remote fi-om the eyes at the sides, in the middle much 

 deflexed and a little interrupted ; the surface coarsely 

 punctured, the punctures rather close towards the front, 

 widely separated at the vertex. Thorax broad, very 

 nearly as long as broad, much narrowed behind, a little 

 rounded at the sides, the front angles greatly rounded; 

 the surface sparingly and coarsely punctured, the punc- 

 tures consisting of two divergent, rather widely separated 

 series along the middle, wnth accessory punctures between 

 them on the front part, and outside them with a few other 

 punctures; the depression at the hind part of the main 

 series is only slight. Elytra about one and a half times 

 as long as the thorax, pitchy in colour, with a broad straight 

 stripe at each side testaceous ; they are rather sparingly 

 and coarsely punctured, the punctures becoming more 

 sparing towards the extremity. Four basal segments of 

 the liind body with imbricate sculpture. Legs almost
