Ovipositor rather small, moderately constricted in the middle. Ostium 
narrow; limen, a small transverse plate, emarginate in the middle above. 
Two transverse ovate haired plates above the ostium, two smaller oblique 
plates below this. Ducuts bursae with a slender tubular colliculum, con- 
stricted above its lower extremity, membraneous beyond the colliculum, 
and spiraled above the bursa copulatrix which is simple. (Slide no. 899 D, 
type.) 
‘ Moss Forest Camp, 2600—2800 m, October 9— November 5, 1938. One

suffused with dark grey from beyond the base to below the apex, apex pure 
white; terminal segment fuscous. Abdomen greyish, tergites with broad 
transverse bands of coppery-orange bristles, showing through scales, 
posterior edges of the segments broadly white. Legs sordid white, anterior 
leg blackish above. Fore wing broad-lanceolate, costa curved, less so in 
the middle, apex rather long, pointed, termen hardly sinuate, considerably 
oblique. Glossy white, suffused with pale leaden-grey except in the median 
third of the disc, where a longitudinal pure white patch extends from 2 / 5 
to before the apex, and is moderately dilated at 3 / 4 of the wing length; base 
of the costal edge, black; a blackish ill-defined suffusion on the base of 
the wing, extending as an attenuated marginal streak, becoming an 
irrorated line posteriorly, reaching to about the middle of the dorsum, a 
moderate elongate patch of black irroration above the fold slightly beyond 
its middle, and a few scattered black scales in the middle of the disc above 
this; pale leaden-grey marginal suffusion becoming rather dark grey on 
the apical third of the wing; stiff darker grey patches of ill -defined suf- 
fusion along fifth sixth of the costa and in the apex ; a subtriangular 
elongate spot of a sparse black irroration in the upper half of the disc 
below the above mentioned grey costal suffused spot; a few black scales 
scattered over the wing. Cilia white, a suffused light grey patch opposite 
the apex, preceded by two broad ill-defined bars of the same colour on 
the costa. Hind wing glossy ochreous-wliite, cilia snow-white.

an obtuse projection, being the limen proper. (Slide no. 1122 D, type.) 
Lower Mist Camp, 1400—1600 m, January 8, 1939. One specimen.
