 smooth and polished, or at most with a few, sparse, minute punctures 

 scattered over the surface, the face and mesopleura more distinctly punc- 

 tate, the metathorax rugulose and completely areolate, the areola hex- 

 agonal. The abdomen is pointed at apex and a little longer than the 

 head and thorax united, smooth and polished, excepting that the sur- 

 face of the petiole, the second dorsal segment and the third to a slight 

 extent, if examined under a strong lens, appear very finely coriaceous, 

 the thyridia on the second being represented by faint transverse 

 depressed lines near the base.
