pollen in the sutural depression conspicuous. Abdomen with consider- 

 able white pollen along the sides, and with the posterior margins of 

 the segments blackish in certain lights; hypopygium dull black; lam-

 der stem at right angles to this outer part (Fig. 7). 



Legs entirely black ; fore coxas with black hairs and bristles ; femora 

 with a slight greenish lustre; all the tarsi about as long as their tibiae, 

 the first joint of hind tarsi a little longer than the second.

Wings strongly tinged with blackish, more hyaline on the basal and 

 posterior portions ; fourth vein ending close to the tip of the third

 the sides nearly parallel, and the pollen of the abdomen so laid on as
