lines, these often connected at middle and near apex by two narrow and 

 sinuous black crossbars; antennae and legs yellow. Thorax slightly longer 

 than wide, convex, narrowed in front, sides feebly curved on apical half;

 punctured. Elytra gradually tapering from base to apex, striate-punctate.

 latter as long as fourth. Thorax distinctly longer than wide, sides feebly 

 rounded; disk sparsely and rather coarsely punctate; hind angles long, 

 strongly carinate. Elytra gradually attenuate from middle to apex, striae 

 coarsely punctate; intervals subconvex, finely and sparsely punctulate.

 bescent with short, suberect hairs; antennae and legs reddish-brown. An- 

 tennae strongly serrate, second joint not more than one-third the length of 

 third, the latter as long as fourth. Thorax slightly longer than broad, sides 

 nearly straight, feebly divergent from near apex to tips of hind angles, 

 which are prominent, subacute and finely carinate; surface rather densely 

 and coarsely punctured. Elytra feebly tapering from near base to apex;
