Uranothauma delatorum, sp. n. (Plate V. figs. 21, s ; 22, 2 .) 

 Hijreus falkensteinii Butler (uec Dewitz), P. Z. S. 1895, p. 733. 



Wing-expanse: s 32-35 mm., 2 30-32 mm. 



Very closely allied to U. falkensteinii Dewitz. 



Structure. — Fore-wing with the costa very slightly curved, the internal margin 

 straight and about four-fifths of the length of the costa, the external margin slightly 

 convex outwardly. In some specimens veins 12 and 11 nearly touch one another, in 

 others they anastomose ; in the male vein 6 arises from 7 beyond the end of the 

 cell, thus shortening the sex-streak in space 6, while in the female 6 arises at the end 

 of the cell. Hind-wing about equal in length to the internal margin of the fore-wing, 

 the costal margin slightly sigmoid, the external margin convex, and the anal angle 

 distinctly produced ; the general shape being the same as in U. cordatus E. M. Sharpe ; 

 the tail on vein 2 is much longer and thicker than that of U. falkensteinii. 



<3 . — Upperside. Dark cinnamon-brown, darker towards the external margin and 

 with a general purple gloss. Fore-iving with the sex-streaks appearing as internervular 

 blackish lines, the cilia broadly chequered with dark brown and white. Hind-imng 

 with the costal and internal borders sepia-brown and lacking the purple gloss, and 

 there are usually a few metallic blue-green scales at the anal angle, and again just 

 above the tail ; cilia dirty white, narrowly interrupted with brown on the veins. 



Underside. Fore-wing : ground-colour varied from light sienna-brown at base to 

 a cloudy light sepia-brown distally, being greyish white in the median area. The 

 markings are sepia-brown edged with creamy white: at base of the discoidal cell a 

 small dark triangular patch ; beyond this a bar at the origin of vein 2, reaching to the 

 costa, and another on the discocellular veins ; a post-median band starts from the 

 costa, where it is very broad, and continues towards the tornus as far as vein 2, 

 becoming gradually narrower and less distinct ; the lateral edges of this band are more 

 or less sinuate, and its costal edge is interrupted by a small white spot ; between this 

 band and the discocellular bar there is a small dark spot on the costa ; midway 

 between the discocellular and post-median bands lies an oblong transverse spot in 

 space 2, with a similar one adjoining it in space 1, this latter being sometimes absent. 

 In TJ. nubifer the spot in space 2 is always more or less attached to the post-median 

 band, in JJ. delatorum never. Hind-wing : ground-colour lustrous creamy white. 

 The markings are of the darkest shade of sepia-brown and comprise a roughly triangular 

 basal marking extending halfway along the inner margin, the apex being a little 

 beyond the origin of vein 2, where it touches the discal band, which extends from the
