166. Castalius ananda, de Nicc^ville, 

 A single male at 3,500 feet in June. This species would appear 

 to be more suitably located in the genus Tarucus, Moore, as it agrees 

 much better in markings with species of that genus than with species 

 of Castalius^ and the marking is the only point on which Mr. de 

 Niceville has been able to separate the two genera in " The Butter- 

 flies of India, &c." As however the differences in neuration and shape 

 of wing, on which Moore separated Tarueus from Castalius^ are not 

 even specific, but rather individual, and since both genera are practi- 

 cally coincident in range and identical in habits, their separation is of 

 doubtful value. 



167. PoLYOMMATUs BCETicus, Linnseus. 

 Common in the hills up to 7,000 feet. 



168. SURENDRA QUERCETORUM, Moore. 



Common in the hills up to 3,500 feet. 



169. Arrhopala centauruSj Fabricius. 



Common in the Upper Chindwin from April to June ; also from 

 Manipur. 



170. Arrhopala amatrix, de Niceville. 

 Three females in the Upper Chindwin during May and June. 



171. Arrhopala abseus, Hewitson. 



Six specimens in the Upper Chindwin in May. These differ from 

 typical A. abseus in their smaller size, and in the purple colour on the 

 upperside of both wings being more restricted. The underside is 

 darker, especially the hindwing, and the markings are consequently 

 less prominent ; there is no costal white spot on the hindwing, but in 

 its place a square spot rather lighter than the rest of the ground-colour 

 of the hindwing but of about the same tone as the ground-colouring, 

 of the forewing. The above differences, though constant in the six 

 specimens obtained, do not appear sufficient to separate this form even 

 as a geographical race, especially as typical A. abseus occurs a littl© 

 further south. 



172. Arrhopala atrax, Hewitson. 



Two specimens from the Upper Chindwin in May. 

 173. Arrhopala, sp. 



Two specimens — one from 5,000 feet in May and the other from 

 3,500 feet m June. Nearest to A. atrax and A, alemon^ but not agree-
