Primaries long and narrow. 



Male. — Expands 1.6 inch. Upper side pure white, grey at base of 

 wings ; a large grey patch at apex of primaries, partially replaced by 

 white J costal margin slightly specked with black; on arc a straight 

 black bar, not prolonged above sub-costal nervure. Secondaries have 

 a few black scales at outer angle and a small wedge-shaped black spot 

 nearer base on costa. 



Under side white ; primaries have a small grey subapical patch on 

 costa, netirly covered with green scales, and a faint greenish patch on 

 hind margin in the discoidal interspaces; discal spot narrow, lunate 

 enclosing a white streak. Secondaries crossed by bands of yellow 

 green on a grey ground, the first, near base forming a segment of a 

 circle; the second, just anterior to the middle of the wing, of irregular 

 width, projecting a short, truncated branch on sub-median nervule 

 that connects with the third band, and ending in a sharp spur a lit- 

 tle inside abdominal margin ; the third band, commencing on abdo- 

 minal margin, is at first broad, and after connecting with second band. 

 narrows to half its previous width, then enlarges greatly and curves 

 /towards hind margin, which it strikes in three branches, besides send- 

 ing a fourth to outer angle ; sometimes this last branch is disconnected 

 and forms a marginal spot ; the bands are more or less marked by 

 small white spots and points. 



Body black covered with grey hairs; beneath greenish-white; palpi 

 white, with grey interspersed; antennae grey above, yellowish below ; 

 club brown above, bright yellow below and at tip.
