J89I.] THE NAGA AND KAREN HILLS AND PERAK. 261 



malsara, whilst one sent by Major Bingham from the Karen Hills in 

 February is a perfect rudis. I think there can be no question of 

 the seasonal dimorphism in this species. 



Mycalesis surkha.

Var. ustulata. 



M. ustulata, Dist. Entomologist, vol. xviii. p. 289 (1885); Rhop.

With the exception of the larger ocelli, broader transverse lilac 

 band, and more distinct markings of the underside, in wliich, as 

 Distant says, it forms a transition to the Javan M. oroates, Hew., I 

 see nothing to distinguish il/. ustulata, of which I have two pairs taken 

 by Doherty at Perak in February, from surTcha, which 1 have from 

 Tavoy. The difference is just that which might be expected to be 

 produced by a damper and hotter climate, and I have little doubt 

 that both forms will be found at different seasons in the same locality, 

 if the dry and wet seasons are well marked. 



Mycalesis fuscum.

Taken at Perak by Doherty, and also common in the island of 

 Nias off the coast of Suu.atra (Mogdiliani). 



Mycalesis dohertyi, n. sp. (Plate XXVII. figs. 3 c? , 4 5 .) 



Mr. Doherty sent a pair from the low country of Perak which 

 seem to me, as to him,tu belong to an undescribed species of the same 

 group as the last, in which the base of the costal, m.edian, and 

 submedian veins are much swelled in both sexes, and the male has 

 a tuft of fine silky hairs at the base of the hind wing covering a 

 glandular patch. 



(S . Dark hair-brown above, with an ocellus near the apex of fore 

 wing, another larger one below it. The hind wing has three small 

 ocelli above and two larger ones below. 



Beneath, the wings are paler brown, with a faint broken pale 

 transverse oblique band near the base, another distinct whitish one 

 across both wings not reaching the inner margin of hind wing. 

 OcelH as above but more distinct, the upper one on the hind wing 

 larger but not so large as the fourth and fifth, and two additional 

 small ones at anal angle which do not show above. 



Below, the band ol ocelli is edged on both sides with whitish, and 

 there are two pale marginal zigzag lines of same colour. 



The female is like the male but rather larger, paler above, and 

 with rounder wings.
