128 BDTTEKFLIES. 



80. Ypthima avanta, Moore. 



This species has two seasonal forms : Y. ordinafa, Butler, is the 

 wet-season form; true Y, avanta the dry-season form. I possess a 

 single large female specimen only of this species from Sikhim, 

 captured by my friend the late Otto MoUer in the Terai on 10th July, 

 1881. It is found in Central China. 



81. Ypthima huebneei, Kirby. 



The ocellated form occurring in the rains is true Y. Jmebneri; 

 the dry-season, non-ocellated form is Y. Imvra, Moore. In Sikhim it 

 is confined to the Terai, being a butterfly of the plains rather than of 

 the hills. 



82. Ypthima newaea, Moore. 



Occurs locally in Sikhim from the Terai up to about 5,000 feet 

 from May to September, and is not common. Mr. Leech describes a 

 local race from Central China as Y. neivara, var. chinensis. 



Ilemadara narasingha, Moore, was originally described as an 

 " Ypthima^^ from Sikhim, but it almost certainly does not occur there. 

 It has recently been rediscovered at Bernardmyo in Upper Burmah at 

 5,400 feet elevation above the sea. 



83. Calleeebia anijada, Moore. 



Occurs only in the interior, and has been obtained occasionally 

 only by the native collectors in native Sikhim and Bhutan. Mr. 

 Moore has (erroneously I believe) recorded Dallacha hyagriva, Moore, 

 and CaUerchia scanda, KoUar, from Darjeeling. 



84. ZiPCETES SCYLAX, Hewitson. 



Neither rare nor common. It occurs at low elevations only 

 throughout the year except in the three coldest months. 1 have 

 recently received it from Upper Burmah. It frequents dark places 

 near water. 



85. Ragadia crito, de Nic^ville. 



Has only so far been obtained by native collectors near Buxa, 

 Bhutan, but possibly occurs in Sikhim also. It is a local species, and 

 is found commonly where it occm's in August. Mr. Elwes records it 

 from Margherita in Upper Assam. 



86. Melanitis ismene, Cramer, 



A very common species ; occurs from the level of the Terai up to 

 7,000 feet. It is highly seasonally dimorphic, the wet-season form 

 being usually referred to as M. leda, Linnaeus, but Messrs. Butler and 

 Moore both declare that true 31. leda is a distinct species from 

 Amboina. That being so, the wet-season form will stand as 31. deter- 

 minata, Butler, and the dry-season form as true M. isnwie, Cramer.
