178. LiMENiTis zuLEMA, Doublcday and Hewitson, 



Very rare in Sikliim, less rarely found at Baling in May and June 

 from 1,500 to 5,000 feet; also at ISivoke in April. It occurs also in 

 Assam and Upper Burmah. 



179. LiMENiTis DUDU, Westwood. 



Found from 5,000 to 8,000 feet from June to August in dense 

 forests. Flies round tops of trees on the highest points of ridges. 



180. LiMENiTis (Moduza) procris, Cramer. 

 Common at low elevations from March to December. 



181. Athyma perius, Linnjeus. 



This species is found from Cashmere to Formosa and Hainan, 

 and probably in most of the Indo-Malayan islands. It is common in 

 Sikhim at low elevations, and flies all through the summer. The 

 eastern Darjeeling and Bhutan form is unusually dark, the ground- 

 colour of the underside being suffused with brownish. 



183. Athyma jina, Moore. 



Rare, and confined to the zone of heavy forests between 6,000 and 

 8,000 feet, where Mr. Elwes has taken it in July. It also occurs in 

 April. It is found in Western and Central China. 



183. Athyma mahesa, Moore. 



Common in the low valleys from March to December, Mr. Leech 

 has described a very dark local race of this species occurring in 

 Western China as var. serica. 



184. Athyma opalina, Kollar. 



This .species is at least double-brooded, and is found from 2,000 

 to 7,000 feet elevation from April to October. It is also seasonally 

 dimorphic; the form which occurs in the dry-season (spring) is quite 

 typical A. opalina, while that found in the wet-season is much darker, 

 richer-coloured, and narrower-banded, and has been named A. orkntalis 

 by Mr. Elwes, Colonel Swinhoe says that the latter "appears to be 

 a good constant form," which it certainly is not. He records 

 A. opalina also from the Khasi Hills, but puts two other species of 

 Athjma between it and A. orientalis ! A. opalina occurs in Western and 

 Central China, and Alphdraky has described a variety of it from 

 Choui-tchin-pou as A. orientalis, var, constiHcta. 



185. Athyma selenophora, Kollar. 



Males common, females rare at low elevations throughout the 

 summer. The female was described as a distinct species by Mr. 

 Moore under the name of A. hahula. 



186. Athyma zeroca, Moore. 



Males common, females rare. Occurs from the level of the Terai 

 up to 4,000 feet from March to December.
