286 L. de Niceville — Neiv Butterflies from the Indian Region. [No. 4, 



a very straight discal line as in the forewing from the costa to the first 

 median nervule, from thence to abdominal margin forming a W-shaped 

 figure ; a submarginal fascia as in the forewing ; anal lobe black crown- 

 ed with whitish, inwardly marked with an orange line ; a round black 

 spot crowned with ochreous on the margin in the first median interspace, 

 the wing-surface between it and the anal lobe sprinkled with black and 

 ■white scales, a fine black marginal thread. Cilia reddish- brown through- 

 out. Body concolorous with the wings above, pale yellow below. Head 

 with the frontal tuft and palpi pale yellow. 



Apparently nearest to Hapala nissa, Kollar, w^ith which it closely 

 agrees in the coloration and markings of the underside, though the 

 discal line on the underside is straighter and more even than is usually 

 the case in that species. It differs, however, from B. nissa on the 

 upperside in having the rich iridescent blue reflections, which are only 

 seen in certain lights, and are entirely absent in B. nissa. 



Described from a single specimen taken in Bhutan in April, in the 

 collection of Mr. A. V. Kny vett. 



17. Tajuria istroidea, de Niceville, PI. XIV, Fig. 14, c?. 



T. istroidea, de Niceville, Proc. Zool. Soc. Lond., 1887, p. 458, pi. xl, fig. 3, 

 female. 



Habitat : Sikkim. 

 Expanse : c?, 1*4 inches. 



Description : Male. Differs from the description of " Bemelana " 

 yajna, Doherty,* on the upperside of the hindwing in the glittering azure 

 patch being of greater extent, occupying the anterior half of the discoidal 

 cell, instead of extending into it slightly, and reaching to the costa 

 and to the apex of the wing. On the underside the apex of the fore- 

 wing is concolorous with the rest of the wing, not darker as in B. yajna, 

 the discal Hue is outwardly curved, of a deeper rufous than the ground- 

 colour, outwardly defined by a fine white line, instead of being chiefly 

 white, slender, and sinuous, and without any trace of an outer black 

 bounding line ; the hindwing has the abdominal margin concolorous with 

 the rest of the wing, not partly white as in B. yajna. 



Described from a single specimen taken in Sikkim on 2nd Decem- 

 ber, 1887, in Mr. Otto Moller's collection. The underside agrees exactly 

 in colour and markings with the female, except that the ground-colour 

 is rather darker.
