546 PROCEEDINGS OP THE ACADEMY OP 



vein is adjacent to the external margin, with two marginal nervules from the 

 hinder end of the disk, the first opposite the penultimate branch of the me- 

 dian, the second forked at about its middle. The apical branch gives rise at 

 about its middle to the post-apical. The subcosto-inferior and the discal vein 

 arise at a common point, the latter slightly curved. Median vein 4-branched, 

 the posterior remote from the penultimate. Hind wings equal to the length 

 of the body. Without costal vein. Subcostal vein bifid from the origin of 

 the discal vein, which is very obliquely inclined to the base and suddenly 

 curved about the middle of the disk, where it receives the discal fold ; imme- 

 diately beneath this arises a medio-discal nervule. Median vein bifid from the 

 disk. 



Head rather large, smooth, free ; with ocelli. Face narrow. Eyes rather 

 large, prominent. Antennae shortly pectinated or serrated to the tip, whence 

 it is moniliform, and more or less dilated or fusiform about the middle. Palpi 

 curved, ascending to the middle of the face ; basal joint hairy beneath ; middle 

 and terminal joint smooth and cylindrical. Tongue about as long as the thorax 

 beneath. 



Body cylindrical, smooth. Patagia small. Abdomen obtuse, with a promi- 

 nent tubercle on each side of the basal segment. Legs slender and long ; fore 

 tibiae with a moderate spur from the base ; hind tibiae towards the ends and 

 the hind tarsi plumose. Hind tibiae with two short spurs.

 Westw. ed. Drury ii. 51, pi. 27, f. 3. Blackish, somewhat tinged with blue. 

 Antennae with ochreous tips. Face yellow, with a blackish central stripe and 

 a yellow spot between the anternae. Thorax with four yellow spots and tegula? 

 striped with yellow on the inner edge. Abdomen with tip dark yellow and 

 banded with the same hue between the segments ; the two segments next 

 the basal banded with white beneath. Wings concolorous dark brown, im- 

 maculate. The fore coxae each with an orange yellow spot ; legs black, 

 middle femora striped with dark yellow ; hind tibiae and tarsi with yellow 

 hairs, broadly banded at the end of each with black.

 tinged with blue. Head, thorax, base of the wings and abdomen towards the 

 base with white dots. Wings blackish brown. Abdominal segments with 

 white bands. Legs partly covered with white scales ; hind tibiae with a white 

 band before the middle, beyond which they are deeply plumose towards the 

 base.

The wings are longer than the body. The anterior rather narrow, envelop- 

 ing the body when folded ; apex obtusely rounded and hind margin slightly 

 oblique. The subcostal nervule gives rise to a marginal nervule, about its 

 middle, and within the disk forms a large secondary cell, from the hind end 

 of which arise three distinct marginal nervules, the lower one reaching the 

 costa rather above the tip. The disk extends rather beyond the apical third 

 of the wing, and the discal vein gives rise to three nervules. The median is 

 3 -branched, the posterior branch being remote from the others and arising op-
