 arcuate, cephalic margin much shorter, arcuato-truncate, lateral 

 margins oblique rotundato-truncate, greatest width distinctly caudad 

 of middle, angles rotundato-rectangulate; disk subdeplanate, lateral 

 portions declivent, oblique sulci distinct. Tegmina elongate sub- 

 lanceolate, subequal in greater portion of length, pronotal length 

 contained about three and one-half times in tegminal length, greatest 

 width contained slightly less than three times in length, apex broadly 

 rounded and extending caudad of apex of abdomen by nearly length
