Uncus weak, almost bipartite, halves clavate. Socius, a large, weak 
pad, with top pointed; inner side of socius moderately bristled above. 
Valva strongly constricted beyond middle, little bent; cucullus sub- 
triangular, with upper angle rounded, lower angle rectangular; with two 
large and numerous small marginal teeth. Aedoeagus rather short, nar- 
rowed. Cornuti, a sheaf of slender bristles. Anellus very strong (Slide No.

markings dark fuscous. Anterior half of costa with a row of small dots, 
larger and smaller dots alternating; dot at about x / 4 produced along disc by 
a narrow outwardly oblique suffused line to cell; somewhat more than 
posterior half of costa with five large rounded suffused fuscous -greyish 
dots, alternating with small points, separated by pale ochreous ground 
colour; anterior of these dots largest, oblique-triangular, ultimate dot 
apical; a patch of coarse greyish-fuscous irroration extending below

lower margin of this patch ill-defined, dentate, reaching below upper edge 
of cell ; base of wing suffused with brighter brown ; a bright brown suffused 
inwardly oblique patch from l / 1 of dorsum, dilated above fold and 
occupying median third of cell; a rounded brownish spot irrorated with 
dark fuscous above dorsum before tornus, just below middle of disc, 
connected by transverse dark greyish-fuscous strigulation with dorsum; 
this strigulation extending between preceding spot and termen, reaching 
along the latter from tornus to below apex ; dorsal edge dotted with blackish- 
fuscous; terminal edge with a narrow dark fuscous streak. Cilia greyish-
