whitish hairs on the anterior part, and a similar band of blackish 

 hairs on the posterior part, of each segment ; the second segment 

 possessing a basal row of short sparse tawny hairs and a bunch of 

 longer white hairs on each side at the base ; the short whitish hairs 

 on the doi'sum may possibly extend over the greater part of the 

 surface, and appear more like scales than hairs. Venter chestnut- 

 brown, vvith irregular black marks and with short white scaly hairs 

 generally distributed over it. Legs tawny brown, fore coxae similar, 

 posterior coxae blackish brown ; hind femora with a few hairs 

 below, posterior tibiae moderately covered with short bristles j. 

 tarsi blackish brown, minutely pubescent below. Wings pale grey,, 

 with a dark brown oblique baso-costal band, which has an indenta- 

 tion on the lower side ; the brown colour extends along the costa 

 to the tip of the first longitudinal veiu, its outer edge extending 

 posteriorly to just behind the second posterior cell, the colour thus 

 filling slightly more than half the first- longitudinal and discal cells,. 

 and extending in an irregularly straight line from the latter cell 

 to the base of the wing, filling half the anal cell; round brown 

 spots, all of equal size, are placed at the tip of the second longi- 

 tudinal vein, at the base of the fork of the third longitudinal and 

 at the tip of the veinlets dividing the second, third, and fourth 

 posterior cells; on the upper corner (adjoining the base of the 

 discal cell) of the lower basal cell a small bluish opalescent spot ; 

 at extreme base of wings and along the stronger veins a distinct 

 tawny colour ; halteres yellowish white.
