men: black, obscurely shining. First segment metallic, the 
segment with a small semicircular yellow brown spot, its 
round side directed medianly, outer side straight. Third 
and fourth segments similar but with larger spots, except 
those on the third are more nearly triangular and the 
rounded angles again are medial, but the greatest length of 
the spot is vertically arranged on the segment; the spot on 
the fourth segment in contrast to the third, is placed trans- 
versely, but is angular — the angle placed medially. None of 
the spots touch the sides, and all are widely interrupted. The 
spots of the second segment may be wanting and on the fifth 
segment there may be more traces of yellow. Pile of abdo- 
men long on the sides, pale in color, almost wanting on the 
surface but the surface is thickly beset with black, appressed, 
very short hair or bristles. Sides of abdomen parallel, much 
inrolled. Legs : black, tarsi very dark brown, extreme base 
of fore tarsi and apex of femora light brown. Wings: pale 
brown, stigma darker.
