 scattered pale setae on posterior half; pruinose area at dorsal posterior 

 corner in form of rectangle, one side extending two-thirds distance to 

 ventral posterior corner, the other side extending about half way to 

 anterior spiracle, Sternopleuron with ventral corner pruinose, a 

 broken medial pruinose band extending from pruinose corner to dorsal

 veins. Second band extends from proximad of tip of first vein to 

 fourth vein over the anterior crossvein, faint between second and third 

 veins. Third band extends from proximad of tip of second vein toward 

 posterior crossvein but not passing third vein. Fourth band consists 

 of relatively large spot at tip of third vein. The part of first basal cell 

 contiguous to second basal cell completely hyaline. Section of fourth 

 vein proximad of anterior crossvein with very slight bend. Anal angle
