Foi-ewings : pale ochreous, varied with rnfons scales, as fai- as the second line, 

 and densest at base ; lines rufous ; first at one-third, curved; second at two-thirds, 

 denticulate outwards on the veins, the teeth of veins 3, 4, and i)rominent : third 

 line at five-sixths, parallel throughout to second, followed by a lunulate reddish 

 fascia; marginal line thick, red, swollen along the veins, which are also red beyond 

 third line; fringe reddish; cellspot linear, reddish.

 which it is angulated and then runs obliquely to one-fourth of inner margin; outer

 and dark brown at costa, bent ontwards at vein 6 and inwards on submedian fold, 

 irregularly waved between. Cellspot large, black, with an indistinct ochraceon-s

10. Ptychopoda squamulata sp. nov. 



Forewings: brownish-ochreous, the speckling and lines purplish fuscous; basal 

 half of costa fuscous; inner line from two-fifths of costa and median obliquely 

 curved inwards and parallel as far as the median vein, where the median line 

 becomes divergent; within the inner line and near it is another less distinct; outer 

 line sinuous, at four-fifths, followed by a sinuous purplish grey shade, which is 

 partially obsolescent towards costa and is edged by the submarginal line beyond 

 which is another grey shade; cellspot fuscous: fringe concolorous with wings, with 

 a median line formed of dots of blackish scales beyond the vein ends.
