Differs from the type species, and from olitescens, not only by the smooth 

 outer margins, but also by the entire absence of the pencil of hairs and patches 

 of dark scales. The anastomosis of costal and subcostal of hindwing is common 

 to all. 



57. Gerusia virescens spec. nov. and ab. viridirnacula nov. 



Forewing : pinkish ochreous, overlaid with very pale green and covered with 

 fine black atoms ; the lines olive-green, indistinct ; first curved from one-fifth 

 of costa to one-fourth of inner margin, marked by a dark spot on snbmedian 

 vein ; median outenrved from about middle, becoming obsolete below ; outer line 

 from two-thirds of costa, oblique outwards and sharply angled on vein 0, then 

 oblique inwards, vertically curved from vein 2, marked by dark dots on veins ; 

 Bubmarginal line white, preceded by a greener shade, angled inwards at G to 

 angle of outer line and there marked by a hyaline white spot, on the two folds 

 preceded by two blackish spots ; fringe olive-brown, with broad pale yellow 

 chequering at the veiu-ends ; cell-spot green; central area often more suffused 

 with green than the rest of wing. 



Hindwing : above middle dull whitish with a pinkish tinge, speckled with 

 green, below hyaline white, green-speckled ; a broad straight antemedian line, 

 curved lunulate-deutate postmedian, and waved snbmarginal ; marginal area below 

 4 dull grey-green, its inner edge straight ; fringe olive-brown, with basal line 

 and teeth pale yellow ; cell-spot green ; base of cell below subcostal vein with a 

 long patch of black scales. 



Underside of forewing ochreous, green-speckled ; the lines broadly green, the 

 apex and anal angle green ; in cell some rust-coloured scaling ; margin below 

 middle yellow, inwardly limited by a curved reddish line ; inner margin whitish ; 

 the pencil of hairs from base black : hindwing sprinkled with green ; the cell 

 dull pink ; antemedian line dark at inner margin ; marginal area below middle 

 darker green with a brown patch containing two pale ochreous spots. 



Palpi externally greenish, white within and below ; face dark green, white

 with pink, with pairs of green dorsal spots ; abdomen beneath and legs cream-

In three of these — ab. viridirnacula — the sinus of outer line across the 

 gubmedian fold is filled with a large round blackish gree blotch.
