( HO ) 



covered by a long pencil of black Lairs from base; and the hindwing has a 

 corresponding patch of black scales along the upper half of cell above ; below the 

 median vein of hindwing from base to two-thirds the wing membrane is hyaline 

 white. 



Nenration : forewing, cell longer than half of wing; discocellnlar vertical, 

 very faint, slightly concave outwards ; first median nervule at two-thirds, second 

 at eight-ninths ; radials normal ; 7, 8 stalked from the bend, 9, 10 stalked jnst 

 before, 11 free, anastomosing at a point with 12, 9, 10 anastomosing with 11, 

 9 again with 8 : hindwing, costal anastomosing with subcostal shortly in basal half 

 of cell ; 7 and 3 from before ends of cell ; radial from centre of discocellnlar. 



Type : Gerusia virescena spec. nov. 



55. Gerusia olivescens spec. nov. 



Forewing : glossy cream-colour, speckled with olive ; the lines and shadings 

 deep olive-green ; lines as in viridescens, but thicker and more strongly marked ; 

 basal patch wholly olive, separated from first line by a narrow line of pale 

 ground-colour ; median shade diffuse, incurved below middle and ontcurved again 

 to inner margin near outer line ; a deep olive-green cloud along submedian interval 

 from beyond basal line to beyond outer line ; outer line dark greeD, with a diffuse 

 shade in the angle, followed by a costal triangle of green edged by the pale 

 submarginal line ; a grey-green patch on the margin from 7 to 4, and another 

 below middle reaching outer line and traversed by the luuules of submarginal line ; 

 two blackish green spots before this line on each fold ; fringe olive-green, with 

 pale spots on the veins. 



Hindvoing : with the lines as in viridescens, but all deep olive-green; costal 

 half dull blurred grey-green, with a pink tinge. 



Underside dark olive, with all the pale spaces sulphur-yellow ; some red 

 scales between veins 2 and 4 on cacli wing, and orange and yellow dots along cell 

 of hindwing ; spots at anal angle of hindwing yellow. 



Palpi olive-green externally, white within and above ; face olive-green, pale 

 below ; vertex and antennal shaft white ; prothorax olive-green ; apical half of 

 patagia, metathorax, and two basal segments of abdomen greenish white ; rest 

 of dorsum olive-green with the segmental rings white ; abdomen beneath, legs, 

 and pectus ochreous dotted with green. 



Expanse of wings : 44 mm. 



2 at. 



Differs from the type species, virescens, in having no dark scales on either wing 

 at base, and the pencil of hairs from base of forewing smaller and paler. 



56. Gerusia rasimargo spec. nov. 



Forewing : almost exactly like that of G. viridescens, but the lines pale 

 olive-brown, and the costa olive-brown at base ; a snow-white streak from apex 

 to the hyaline spot on vein G ; fringe olive-brown ; outer margin smoothly rounded, 

 without trace of teeth or crenulations. 



Hindwing : costal half paler green, rust-coloured towards apex ; lines brown, 

 runch as in viridescens but more distinct ; an additional bent shade just beyond 

 postmedian line; space below middle not hyaline white; fringe olive-brown; 

 outer margin well rounded, with hardly an judication of teeth.
