to those of U. costistrigaria, but the bands, which are fuligi- 

 nous grey in colour, are narrower, and there are fewer streaks 

 on the costa, and these are confined to the basal area with 

 the exception of a streak between the first transverse band 

 and the short central band ; on the outer area of the wing 

 there is a fuliginous grey band, which is very broad towards 

 apex, but tapers slightly to the first median nervule, whence 

 it is continued in slender streaks to inner angle : on the 

 secondaries the transverse band is also narrower and the cloud 

 on outer area is greyish and suffused with paleochreous. Above 

 the tail, which is rather broader and more obtusely produced, 

 there is a large reddish spot, and below it another spot of the 

 same colour ; both are ringed with black, and there is an 

 elongated black spot nearer the anal angle. Under surface : 

 markings of upperside reproduced, but the central bands are 

 fainter and narrower and that on outer area much darker; 

 the secondaries have some dark grey shading along outer 

 margin.

White ; primaries traversed by two rather broad oblique 

 brownish bands, becoming blackish towards costa; a shorter 

 and narrower band between them, commencing in a darker 

 spot on costa and terminating in first median interspace; 

 basal area of costa streaked with dark brown j these streaks 

 are short near the base, but the outermost extend almost to 

 submedian nervure ; the outer third is heavily striated and 

 clouded with fuliginous ; the costa between the broad bands is 

 also streaked with brownish; fringes brown from apex to just 

 above termination of submedian nervure, and thence white, 

 except where interrupted by continuation of the broad trans- 

 verse bands : secondaries traversed by an oblique brownish 

 band from fork of subcostal nervure to a large cloud of the 

 same colour on outer area ; the abdominal area of the wing 

 is clothed, except towards anal angle, with long silky hairs 

 of a creamy colour ; above the tail, which is obtusely pro- 

 duced, there is a reddish spot ringed with black, and below it 

 there is an elongated blackish mark ; fringes fulvous brown, 

 except at costal and anal angles. Head snowy white ; face 

 brown ; collar creamy. Under surface white, discal markings 

 on upper surface of primaries faintly reproduced ; outer area 

 broadly fuliginous as far as submedian nervure : the second-
