coalescing with the dusky margin. Underside with the basal area dark umber brown, cross- 

 ed by a prominent silvery white subbasal streak on both wings. Forewing with a white oblique 

 transverse discal band tinged with yellow, joined at the middle by a pale band from the apex, 

 formnig together a Y-shaped figure, and enclosing a dark brown triangular patch ; a row of 

 six ocelli on the outer pale band, the sixth geminate, all grey with irregular black pupils, 

 and circled with pale brown and violet ; the area beyond the ocelli yellowish, shading into 

 dark brown towards the margin, and grey at the apex ; two ochreous marginal lines sharply 

 defined with black lines. Hindwjng \v\\\\ %\x very large ocelli, all profusely irrorated with 

 white, and all, except the first, disintegrated, the whole enclosed by a silvery lilac line ; an 

 outer ochreous and an inner silvery marginal line both sharply defined with black. Ci/ia 

 ochreous. Female similar to the male, but paler coloured ; on the uppkrside the foreivlng is 

 crossed from middle of costa to outer angle by a broad straight pure white bnnd, the subapical 

 spots are pure white ; and on the hindwing the submarginal black spots are more prominent. 

 Underside similar to the male, but having in addition a broad transverse white bar on fore- 

 wing which more or less obliterates the two lower ocelli. 



This is the type corresponding with L. arete of Cramer, which is common in Sikkim, Assam, 

 Sylhet, Upper Tenasserim, Calcutta, South India, and the Andaman Islands. There is another 

 form corresponding with L. bero'c of Cramer, in which the basal portion of the wings on the 

 underside is much paler, and the silvery subbasal streak is broadly bordered externally on the 

 hindwinfT, and up to the cell of the forewing with pale grey. This form was found commonly 

 in the Barrackpore Park in November, by Major Marshall, and was taken by Captain C. T. 

 Bint^ham in Upper Tenasserim from December to April. The only specimen from Calicut in 

 the Indian Museum seems to be intermediate between the two forms. The specimens from 

 the Andamans are the largest and darkest of all. It occurs also in Orissa, but has not been 

 recorded from Ceylon ; and Mr. de Niceville has taken it in Sikkim, in October. Its range 

 is exceedingly wide, and it is the only Lethe that we know to occur in the plains of 

 India, 



Mr. Kirby in his supplement places L. arete as a distinct variety.
