 oblong-ovate, convex, coarsely punctured, the punctures, which 

 have each a single adpressed hair similar to those of the thorax, 

 arranged in striai near the suture, placed irregularly on the disk; 

 interspaces between the striae smooth, those on the outer disk 

 coarsely elevate-reticulate ; humeral callus thickened, prominent,
