outer ones pupilled with white. Underside paler brown, thickly striated throughout with 

 deeper brown. Both wings with a common dark brown subbasal fascia commencing at the 

 subcostal nervure of the forewing, and ending at the median nervure of the liindwing : also 

 with another wider and more prominent deep brown fascia commencing at the costa of the 

 forewing, cutting the cell just beyond its middle, and crossing the hindwing beyond the 

 cell in an inwardly curved line, and ending at the abdominal margin. This fascia is faintly 

 bordered with pale brown outwardly on the forewing, more broadly and with a paler shade 

 of the same colour on the hindwing. The outer margin of both wings of a deeper brown 

 than the ground-colour, this border terminating on the hindwing at the tail, from thence to 

 the anal angle the margin is but little deeper than the ground. Fore7ui>ig crossed by a straight, 

 transverse, outwardly sharply defined deep brown fascia, commencing at the costa, crossing 

 the wing just beyond the cell, and not reaching the inner angle. This fascia is outwardly 

 bordered with a band of pale brown. A submarginal series of three spots, the lowest in the 

 interspace above the third median nervule somewhat large and white ; the one above it black, 

 pupilled with white and with a yellow iris ; the third in the next interspace very small and 

 white. Hindwing with a submarginal series of seven oval black ocelli, pupilled with white, 

 and with yellow irides ; the first the largest, the fourth and fifth also large and nearly equal in 

 size, the sixth and seventh geminated. (Described from Cramer's plate). 



" Male : Upperside differs from the female only in having the transverse band more 

 rufous and nearer the apex, the underside darker, with the ocelli of the hindwing much larger 

 and more distinct." {Heivitson, 1. c.) 



The next species was originally described as a Melanitis, but was subsequently separated 

 by Mr. Butler on the grounds stated below. The differences appear to be sufficiently marked 

 to warrant generic separation. 



Genus 29.-CYLL05E1TSS, Butler. (Plate XIII), 



CyUogenes, Butler, Cat. Lep. V,. M., Satyn\f,s, p 6 (1868) 



"Differs from Melatiitis in the violet colouring of the upperside ; the concave form of the 

 disco-cellulars of the /orewing ; the more wedge-shaped cell of the hindwing ; and in the presence 

 of a large silky dark patch in the forewing of the male." (Butler, 1. c.) 



Only a single species is known, which inhabits Sikkim ; it has a short, curved, yellow 

 band near the apex of the forewing in both sexes. 



254- CyllO^enes SUradeva, Moore. (Plate XIII, Fig. 30 (? ? ). 



Melanitis suradeva, Moore, Horsfield and Moore, Cat, Lep. E. I. C., vol. i, p. 223, n. 469 (1857). 



Habitat : Sikkim. 



Expanse : 3 inches. 



Description : ♦' Male : Upperside deep vinaceous-brown, darkest at the apex, and 

 having in some lights a purple gloss. Foi eiutng \\\ih. a large black patch in the middle; a 

 short narrow obliquely-curved yellow subapical streak. Underside dull ochreous, suffused 

 with brown, and covered with short, narrow, undulating stria;, as in Melanitis leda ; a transverse 

 darker streak across the middle of both wings ; four small whitish submarginal spots on the fore- 

 wing, and two near the anal angle." (Moore, 1. c.) In the specimen in the Indian Museum, 

 Calcutta, the male has also on the underside a purplish-white cloudy discal band on both 

 wings beyond the darker streak. The female differs from the male in having the wings much 

 broader, the yellow band broader, reaching the costa and extending partially along it, and 

 it lacks the dark silky patch on ihe Jorrwing ; on the underside it is paler, and lacks the 

 transverse purplish-white band. 



C. suradeva appears to be a very rare insect. Colonel A. M. Lang, R.E., has five males 

 in his collection, all from Sikkim, and Mr. Otto MoUer has taken a female specimen also in 

 Sikkim. The figure is taken from a male and a female from Sikkim in the Indian Museum, 

 Calcut ta, and shows the uppersides only.
