twice as broad as loug ; sides rounded, narrowly margined, 

 straiglit and diverging from the base to the middle, all the 

 angles produced, the hinder ones acute, the anterior ones 

 excurved, the apex obtuse; disc smooth and shining, faintly 

 excavated on either side near the middle. Scutellum black, tri- 

 gonate. Elytra broader than the thorax, parallel, convex, not 

 impressed below the basilar space, rather closely and somewhat 

 strongly punctured.

Vertex shining, impunctate; encarp^e separated from the front 

 l)y a transverse groove, thickened, subtrigonate, their upper 

 lialves contiguous; carina raised, its apex extending iqjwards 

 l)etween the lower halves of the encarpa^; antennaj much longer 

 than the body, filiform; the third joint one-half longer than 

 the second, the fourth ecjual in length to the two preceding 

 united. Thorax twice as broad as long; sides sinuate near the 

 l)aae and apex, rounded in the middle, the anterior angles 

 pi'oduced. slightly thickened, obtuse; basal mai'gin sinuate- 

 (jtnarginate just in front of the scutellum ; disc convex, minutely 

 punctured, the punctures only visible under a deep lens. Elytra 

 l)r()ador than the thorax, narrowly oblong-ovate, convex, as 

 finely punctured as the thorax; each elytron with a large wedge 

 shaped excavation, which, commencing just below the shoulder 

 and increasing in depth and width towards the apex, runs down- 

 wards on the outer disc to just below its middle, the apex, 

 Avhich is rounded, is surrounded hy a strongly raised callosity, 

 which forms a transverse hump extending nearly across the 

 disc of the elytron, the outer edge of the fovea is also nai'rowly 

 thickened for the lower half of its course.
