 $ , 26 mm. 



Face black. Palpus black, the basal joint drab. Vertex and front 

 of thorax white. Antennal shaft white, pectinations ochreous. Thorax 

 and abdomen mostly concolorous with wings, patagia mostly green, a 

 slight ochreous (possibly discoloured from green) dorsal patch at base 

 of abdomen. Fore wing deep fleshy (a blend of pink, ochreous and 

 white scales) , with olive-grey irroration or strigulation ; in front of 

 cell paler, in front of subcostal stalk and SC 4 mottled with darker 

 gray ; cellspot larger than a dot, black-grey ; antemedian line faintly 

 suggested in white, curved ; postmedian fine, white, excurved anteriorly, 

 then oblique inwards ; an irregular subterminal white line rather near 

 the postmedian, from costa to E 3 enlarged into interneural spots, 

 between the radials incurved, at R 3 — M' strongly excurved, behind 

 fold slightly oblique inwards ; between the postmedian and subter- 

 minal, from SC 4 to hindmargin, a series of green spots, finely divided 

 by veins of the ground-colour ; a series of anteterminal white spots, 

 except at R 2 — M 1 , where there is a longitudinal browner area ; between 

 the subterminal and anteterminal spots the colour is green from costa 

 to R 1 and irregularly banded with purple-grey between R 3 and hind- 

 margin ; terminal spots irregular, blackest between M 2 and SM 2 ; 

 fringe white, with various mottlings. Hind wing to beyond middle 

 with ground-colour as fore wing, becoming green-mixed at end 

 (especially posteriorly) and basewards along abdominal margin ; cell- 

 spot as on fore wing ; a broad white postmedian band, slightly in- 

 curved between the radials, then slightly constricted by a small 

 projection of the green shade between R H and M 1 ; a narrower, some- 

 what macular antemarginal band ; area between the bands rather 

 densely irrorated with grey ; terminal line olive-brownish ; fringe as 

 on fore wing. Underside more densely irrorated with darker grey, 

 especially on the dark cellspot and two white outer bands.
