186 Mr. A. G. Butler on Lepido'plera 



A pair obtained at Sheemagar on the 12tli December, and 

 a male thirty miles above Mandalay on the 14th. 



This is the commonest form of the L. ale.xis group, and we 

 have specimens from Assam, Silhet, Deyra Doon, Poona, 

 and Calcutta. Though hitherto regarded as a variety of L. 

 alexis^ it has as much claim to specific rank as any of tlie 

 species of the L. elpis group, the differences being precisely 

 of the same character as in the variously named forms of that 

 group. 



26. Castalius rosimon, Fabr. 



Five examples (of both sexes) were obtained on the 1 2th, 

 14th, and 21st December at Sheemagar, tliirty miles above 

 Mandalay, and at Kyouk Myoung (lat. 22° 34' N.). 



27. Castalius approximatus^ sp. n. 



Nearest to C. chota, but running larger : it differs chiefly 

 from C. rosimon in the narrower borders to the wings and in 

 the absence of the last of the discal black spots towards ex- 

 ternal angle of primaries, the other five spots being well sepa- 

 rated ; also in the absence of the black spot close to the border 

 of the secondaries towards apex, and in the indistinct and 

 minute character of the marginal spots on the under surface. 

 Expanse of wings 31-32 millim. 



A pair taken at Katha, on the Irrawaddy (lat. 24° 9' N., 

 long. 96° 17' E.), January 3, 1886. 



We have a pair of this form taken in Bombay by Colonel 

 Swinhoe. Whether it is a species or only a well-marked 

 variety nobody can definitely decide without breeding it ; at 

 any rate it is as distinct as the other named forms of the 

 gi-oup. 



2^. GyaninSj sp. 



A single worn male of a species near to C. piispa (and 

 which I have been unable to identify) was taken on the 3rd 

 January at Modah, on the Irrawaddy (lat. 24° 18' N., long. 

 96° 26' E.). We have a second poor specimen of the male 

 from Silhet, and what I suppose to be the female from Dar- 

 jiling ; but none of our specimens are sufficiently good to 

 describe. 



29. Zizera otis, Fabr. 



A male taken at Sheemagar on the 12th December and a 

 female at Modah on the 2nd January. 



Z. lysizone of Snellen is identical with this species.
