 single piece with the front, its anterior border angulate-emargi- 

 nate, angles of the notch slightly produced, subacute; middle of 

 the front irapressedwith a faint longitudinal groove ; jaws piceous, 

 their apex black ; antennae nearly equal to the body in length, 

 eight outer joints closely clothed with adpressed concolorous hairs, 

 the second and third joints short, equal, the fourth and following 

 compressed and very slightly dilated, the joints after the sixth 

 very slightly diminishing in width towards the apex. Thorax 

 twice as broad as long ; sides rounded, angled behind the middle, 

 notched just in front of the hinder angle ; upper surface deeply 

 but remotely punctured, the punctures irregularly scattered over 

 the whole disk; just behind the anterior margin is a transverse 

 groove, its surface impressed with a single row of deep punctures. 

 Scutellum nearly twice as long as broad, sides converging back- 

 wards. Elytra much broader than the thorax ; sides nearly 

 parallel ; apex broadly rounded ; the hinder portion of the lateral 

 border very narrowly dilated ; convex, very slightly excavated 

 below the basilar space, sulcate within the humeral callus, the
