whereas in W. Grayii the posterior cross-vein is some way nearer 
the base of the wing, and the bases of the fork cells are much 
nearer one another than in W. Grayii , and the stem of the 
second posterior cell is a little shorter relatively to the cell. 
Without a minute examination they would certainly be con- 
siderered the same species. 
A microscopic examination shows, however, that the meta- 
thoracic bristles are differently arranged, the chaetae being in 
one line, with smaller chaetae between the four larger ones. 
These small chaetae often, however, are nearly as large as 
the others, as many as nine may occur.

Thorax shiny black when denuded, with deep bronzy-brown 
scales; pleurae dark in front, pallid posteriorly, with white 
scales | prothoracic lobes with white scales. Abdomen dusky 
brownish-black above, creamy-white below, especially at the

Thorax deep shiny black, with small flat spindle-shaped deep 
bronzy scales, some grey ones in front, and a few small pale 
golden hairs projecting over the 
head, broader pale dusky flat ones 
over the posterior part; pro- 
thoracic lobes black, with grey and 
brown scales and six brown bristles 
projecting over the head, three on 
each lobe (Fig. 288); scutellum 
bright ochraceous (denuded) ;
