NYMPHALID/E. SATYRIN.'E. LETIIE. 159 



Tenasseiim, at an elevation of 3,000 to 6,000 feet. In Sikkim it is far less commonly met with 

 than L. rohria ; in the North- West Himalayas it is L. vet ma that is most frequently seen. 

 The figure is taken from a male specimen from Siiillong in Major Marshall's collection. 



147- Letho masoni, Elwes. 



Debts (Tansima) tKasont, Elwes, Proc. Zool. Soc. Lond., 1882, p. 405, pi. xxv, fig. 2. 

 Habitat : Sikkim. 

 Expanse : 23 inches, 



Descriptio.n : "Resembles Z. verma, Kollar, in general appearance, size, form, and colour; 

 but is distinguished on the upperside by a single white spot near the apex of the fon-mu'l 

 which wing is slightly undulate and fringed white. The anterior angle of the /^/«./tot«^ is bordered 

 and fringed white. On the underside there is one ocellus close to the white spot near the 

 apex of the foreioing, and the ground-colour of the hindioing\% overlaid with greyish scales, 

 and without the transverse steely bands of Z. venna. The ocelli resemble those of Z. v.-rma 

 in number, size, and position, but are ringed with hair-brown instead of fulvous. The 

 sexes do not differ." ^^Ehues,\.c.) On the underside of the hindvving there is in the figure a 

 short subbasal dark brown line, a sinuous one beyond crossing the middle of the cell and reach- 

 ing the costal and abdominal margins, a short one defining the disco-cellular nervules, and a 

 fourth very sinuous one across the disc from the costa to the submedian nervure. 



In describing this species Captain Elwes writes: " Of this species, which, though 

 allied to Z. venna, is very distinct, I received a large number of specimens which do 

 not vary. As this insect has never been taken before, I imagine it to be from the Cluimbi 

 valley, on the other side of the Passes, but it is probably not found at extreme 

 elevations." 



148- Lethe siderea, Marshall. 



L. siiicfca, Marshall, Journ. A. S. B., vol. xlix, pt. ii, p. 246 (18S0). 

 Habitat : Sikkim. 

 Expanse: 2'i inches. 



Description : Male : Differs from Z. sulonis, $ , in being smaller, and in the uniform 

 absolutely spotless upper surface, somewhat darker towards the outer margin. Underside 

 uniform brown. Foreioing entirely wanting the discal bands and the whitish spots on the 

 costal margin ; the only markings being three minute submarginal white spots beyond the 

 cell, the middle one faintly ringed with black ; a single yellowish marginal line edged on both 

 sides with dark brown, and within this a distinct silvery-lilac submarginal line extending 

 from the apex to the second median nervule. Hindwing with all the silvery streaks 

 brighter and distinctly lilac ; the submarginal silvery line very slightly dilated at the anal 

 angle ; the ocelli all blacker, and less prominently pupilled with white. The second and third 

 ocelli much nearer the margin than the others, giving the line of ocelli a strong curve 

 outwards, the silvery band within following this curve, and deeply sinuated outwards 

 beyond the cell ; the ground-colour being uniform brown, scarcely at all darkened at the 

 edges of the silvery lines. The hindioingXess distinctly caudate. 



We have only seen two specimens of this species, both from Sikkim, which agree exactly 

 the one with the other. The irregular curve of the series of ocelli on the underside of the 

 hindiuiiig at once distinguishes Z. siderea from all the numerous specimens of Z. siJonis 

 we have seen.
