little shorter than the inner margin, whitli is straiglit. Costal ncrvure reaching the margin 
about the middle of the costa ; the first subcostal uorvulo given oft" from the subcostal nervurc 
a short distance before the end of the cell, second a little beyond the end of the cell, the third 
given off nearer to the cell than to the base of the fourth, reaching the apex, fourth reaching 
the margin below the apex. Upper discocellular ncrvulc very small, directed obliijuely out- 
wards ; middle discocellular also very short, about three times the length of the upper, 
directed obliquely inwards; lower discocellular wanting, thus leaving the discoidal cell 
entirely open. Third median nervule moderately and evenly arched. Subnu-diun uervure 
straight. 
"Hind wixg triangular-ovate, costa gently curved, outer margin sinuate, inner margin emarginate 
at the anal angle, deeply channelled to receive the abdomen. Pra;costal uervure simple, 
strongly curved outwards. Discoidal cell open." {de jyicerllle, I. c.)

Sephisa princeps ? et var. albiniacula, Leeeli, Entomologist, xxiii. p. 190 (1890). 
Primaries with a very deep indentation on outer margin. Ground-colour of all the wings light 
brown, with a purplish reflection in certain lights : primaries with a large irregular-shaped 
black patch extending from the base to about the middle of the wing, suffused down its centre 
with paler ; beyond this patch is a circular black spot ; a black double spot occurs in the cell, 
beyond which are two large black patches touching the costa ; margins of all the wings black : 
an irregular black submargiual baud runs round all the wings, dividing near the anal angle 
and enclosing two circular spots of the ground-colour ; veins deeply marked with black, espe- 
cially near the outer margins. Under surface — markings of primaries reproduced, with the 
addition of a whitish streak along basal half of costa and some whitish spots beyond cell and 
on the apical portion of outer area ; secondaries — all the veins broadly marked with black : 
the ground-colour replaced over a great part of the surface by dirty white. Underside of the 
abdomen white. 
The female agrees with the male, but the wings are rather more ample. 
Allied to Sephisa (Casfalia) dichroa, KolL, and chandra, Moore, both 
Himalayan species. 
Yar. albimacnla. (Plate XIY. fig. O, $ .) Female. Xearly all the fulvous markings replaced by 
white ; the only spots of the typical colour are the two in discal cell of primaries and one on 
costa of secondaries, whilst below the median nervure of primaries theie is a bluish longi- 
tudinal streak instead of a fulvous one. In size, shape, number, and position of the spots and 
dashes, this form agrees exactly with the female type. 
This species occurs ratlier commonly at Chang-yang, and a few specimens 
have been taken at Omei-shan. Fixsen's types came from Pung-tung, in the 
Corea, and I also captured a specimen at Gensan in July. This latter is the 
example described by me as A. cauta in my paper on the " Buttei-flies of Japan
