 tudinal sulcus ; on the front part of the top there is a trans- 

 verse shining black band connecting the eyes, joined to a 

 diamond-shaped black spot on the middle of the vertex, in wliicli 

 is the sulcus; front black; clypeus and labrum briglit yellow, 

 on the former is a row of distant black hairs. Palpi black, the 

 labial enormously long. Antennae black, inserted in yellow 

 sockets ; the basal joint clothed with black hairs. Thorax 

 yellow above, with three longitudinal black bands, one 

 median, the others lateral (on the metathorax the black bands 

 become somewhat vague) ; hairy clothing blackish on the 

 pronotum, whitish and curled on the mesonotum (posteriorly) 

 and metanotum ; pronotum rather broader than long, the 

 front and hinder margins strongly raised: thorax beneath 

 black, sparingly clothed with whitish hairs ; a large yellow 

 spot at the insertion of each pair of legs and also under eacii 

 pair of wings. Legs black, with strong spinose black hairs ; 

 spurs and claws piceous. Abdomen dull yellowish above, 

 passing into blackish after the third segment ; this latter with 

 numerous black points, whence spring cinereous hairs. In

 fourth or fifth segment ; su])erior appendages scarcely longer 

 than the last segment, black, stout, curved upward, cylin-

 a])peudage one half shorter, polished, rounded at the apex, 

 convex beneath. 



Anterior wings broad (especially in the female), the ex- 

 treme apex slightly angular; hyaline, with a very slight 

 greyish-yellow tinge, marked with smoky black as follows : — 

 there are rudiments of three oblique bands, one consisting of 

 a s})ot under the radius in the basal fourth, a second, ante- 

 median, is formed of two spots (often united), extending 

 from the radius half across the wing, the third is post- 

 median and comprises a rather large subradial spot more 

 or less connected with smaller spots below it (all these 

 spots are more or less fenestrated with paler) ; the costal area 

 is strongly marked with black spots rather regularly placed
