$. Adorned, for erotic display, on the head, thorax, and legs. Pubescence 

 snow-white on the frons, white on the vertex and also on the notuoi both in front 

 and laterally half way to the wings, greyish or blackish along the middle of the 

 notum, but posteriorly at the sides of the notum yellowish-white or light ochreous ; 

 here and there at the tips of the hairs the lighter colour shifts to grey. Below the 

 whiter part of the pubescence of the thorax anteriorly, on each side, a large, very 

 dense and compact, arched, epaulet of black hair shelters what is assumed to be the 

 scar of the pupal spiracle. Pleura black-haired ; scales of halteres leaden-black. 

 Short appressed hair of the femora glossy black. Hair and scales of the tibiae and 

 tarsi glossed as follows with impure white or light ochre, viz. : — in the fore leg, the 

 posterior slope of the outer side of the tibia and of the dorsum of the tarsus ; in the 

 hinder legs, the exterior lateral ciliaewith the denser posterior fringe and some scales 

 at the anterior dorsal apical edge of the tibia ; also the posterior dorsal slope of the 

 first two joints in the tarsus, and a few scales on the same side at the apex of the 3rd 

 joint, and also a few at the apex of the 1st joint anteriorly. Palpi blackish-grey, 

 glossed with whitish or yellowish-white. Antennae with very light ochreous scales 

 on the scape and (in this sex) 3rd joint ; the longer hairs of the flagellum light grey, 

 shifting to dark grey or black ; the shorter hairs whitish or light ochreous. 



In 9 > on the above mentioned parts of the head and thorax, cream colour is 

 substituted for white, and an impure whitey brownish-yellow for whitish ; the hair 

 at the sides of the thorax is light yellowish-brown ; the tibial fringes are of a dull 

 colour, and the light markings of the legs are much toned down and reduced in 

 extent. 



Wings above black or greyish-black, with whitish or yellowish-white markings, 

 viz. : — at the base of the wing, a fascia, slightly curved and anteriorly widened, 

 extending from the costal fringe to the axillar nervure and outwards to the bases of 

 the forks ; at the outer limits of the bristling hair, an angulated fascia broken into 

 three unequal spots, of which the foremost and largest, on the radial branches and 

 cubitus, has almost the form of a right-angled triangle truncate at the posterior acute 

 angle ; the second (on the pobrachial branches and postical) in the $ a curved 

 streak, resembles in the ? an inverted comma, reversed in the right wing, with the 

 tail pointing inwards, and the head subopposite the first spot ; the third and smallest 

 is near the end of the axillar ; lastly, at the apex of the wing the fringe from the 

 end of the posterior radius to a little beyond the end of the anterior pobrachial, the 

 light colour also glossing the tips of some of the adjoining hairs. Elsewhere the 

 fringe matches in colour the darker hair of the wing, and is glossed with light 

 brownish-grey, the gloss shifting with change of posture. A blackish line defines 

 the outer and posterior margins of the disc. Pouch in $ closely overlain with long 

 appressed hair parted along the summit and pointing lengthwise obliquely ; the 

 hair whitish at the inner end of the pouch is elsewhere dark. Hair and scales of 

 the under-side of the wing blackish-brown or greyish-black.
