patch on the hindwing being placed in mvich the same position, though it 

 is not quite so large and reaches quite up to the origin of the upper 

 disco-cellular nervule, which it does not do in Bindahara, and it has 

 a similar tuft of long hairs on the forewing ; but it differs from the five 

 Indian genera — Hysudra, Rapala, Bindahara, Virachola, and Sinthusa, 

 all of Moore — which possess the " scale " mark and tuft of hau^s, in 

 being entirely devoid of a tail to the hindwing. The genus is so entirely 

 aberrant that it is veiy difficult to know where to place it, though its 

 affinities are perhaps more with Theda, Fabricius, than with any other. 



31. Listeria dudgeonii, n. sp,, Plate IV, Fig. 3, 6'. 



Habitat : Bhutan. 



Expanse : <?, 1*25 inches. 



Description : Male. Upperside, forewing black ; the discoidal cell, 

 a small area at the base of the second and a larger area at the base of 

 the first median interspace and thence broadly to the inner margin of 

 the wing, but not nearly reaching the anal angle, bright blue. Hind- 

 iving with the costa broadly extending into the cell, the outer margia 

 broadly but decreasingly to the anal angle, black ; the abdominal 

 margin broadly pale fuscous ; the rest of the wing bright blue. Under- 

 .side, foreiving pale fuscous inclining to pale ochreous broadly on the 

 inner margin ; a large reddish spot at the end of the cell, a discal 

 macular reddish band from the costa to the first median nervule ; a sub- 

 marginal broad black-mixed-with-red band ; the sexual tuft of hairs on 

 the inner margin turned under and upwards pale ochreous. Hindiving 

 with the base rather broadly black, the rest of the wing reddish, be- 

 coming darker towards the outer margin, where it is umber-coloured ; 

 beyond the black basal area is a broad ai'ea extending across the wing 

 consisting of a confused mass of ill-shaped ochreous spots ; the outer 

 margin bears a double lunulated fuscous line, each pair of lunules 

 enclosing a small space of the ground-colour. Cilia reddish throughout, 

 broad and coarse, and very long on the hindwing, especially where they 

 fringe the anal lobe. 



The butterfly is so entirely different from all others known to me 

 in shape, markings and sexual characters that I can compare it with 

 none. It remotely reminds one of Thecla frivaldszhyi, Lederer, and 

 allies, in the markings of the underside ; but the coloration of the upper- 

 side, the ti'uucated apex of the forewing, and the " male-marks " are 

 wholly dissimilar. 



Described from a single example not in veiy perfect order, captured 

 at 2,500 feet elevation above the sea by Mr. J. L. Lister, after whom I 

 have much pleasure iu naming the genus. As my friend Mr. G. 0.
