^■Clypeus somewhat narrowed towards the apex, sliallowly 

 emarginate, the angles sHghtly prominent. Antenna inserted 

 nearly one-half as far again from the anterior ocellus as from the 

 base of the clypeus, third joint of flagellum as long as the second. 

 Very closely and rather coarsely punctured; the basal enclosed 

 area of the median segment very finely punctui'ed, with a few 

 indistinct striae, the angles more coarsely striated.
