also on the pleura of the propodeon above the hind coxa, and a much more compact 

 patch on the outer basal half of the coxa itself. 



Wi7igs : fore wings three times as long as broad ; submarginal : marginal : radius : 

 post marginal, 18 : 6 : 1 : 1 (when highly magnified the radius and postmarginal 

 are roughly as 15 : 13). The submarginal vein bears about eighteen bristles from the 

 base of the wing to the two clear transversely placed cells ; the marginal is covered 

 with numerous scales (modified hairs) ; the radius has four cells, the last minute 

 (fig. 2, 2). The submarginal cell has on the under side about twenty-four bristles, 

 half-a-dozen near the base being stronger ; it is not closed, as the marginal vein 

 does not run quite flush with the costa. Where the cell narrows there are a few short

stout hairs, and scales above. The posterior margin of the wing from the base to 

 nearly opposite the end of the submarginal is bare, but behind the submarginal 

 and up to its mid point are three to five rows of hairs ; after this there is a broad 

 < shaped, clear space, the lower arm short, while the upper extends nearly to the 

 beginning of the marginal vein. The middle portion of the wing is occupied by a 

 dark cloud, interrupted only by a large clear spot at the end of the radius and a 

 clear line about twice the length of the marginal, which begins somewhat before 

 the origin of that vein and runs (at one-third) parallel to the hind margin ; the 

 depth of the cloud is due in part to the colour of the wing membrane (which is a 

 little darker below the marginal) and again to the closely set, blackish brown
