1892.] THE NAGA AND KAREN HILLS AND PERAK. 627 



Cupido agnata, Druce, Proc. Zool. Soc. Lond. 1874, p. 106. n. 4, 

 pi. xvi. figs. 2, 4 d , 3 5 . 



Lampides conferenda, Butler, Ann. & Mag. Nat. Hist. 5th series, 

 vol. xviii. p. 185. n. 25 (1886). 



Plebeius malaccanus, Rober, Iris, vol. i. p. 57, pi. iv. fig. 3 S 

 (1886). 



In adopting the name of celeno for this species I follow Mr. 

 Salvin, who has pointed out to me that Cramer's plate exactly agrees 

 with what is usually known as P. ale.vis and H. celianus ; for though 

 Cramer says it comes from Surinam, his plate is unmistakable. For 

 the synonymy I am indebted to Mr. de Niceville. 



It is the type of a group in which the 1st and 2nd bars of the 

 fore wing below reach the costa though broken at the top, whilst 

 the 3rd band extends to the hind margin and the 4th to the 2nd 

 median nervule. A specimen of the wet-season form was sent from 

 Perak, and some of the dry-season form from the Karen Hills. 



Lampides pura. 



Lampides pura, Moore, Journ. Linn. Soc. Lond., Zool. xxi. 41 

 (1886); Butt. Ind. iii. p. 170, front, fig. ]32 $ dry-season form. 



This species, which I distinguish from the last by the very 

 narrow, usually obsolete black border of the fore wing in the male, 

 occurs in Perak, and Doherty took both the wet- and dry-season 

 forms in the Karen Hills. 



Lampides osias. 



Plebejus osias, Roher, Iris, i. (1886, March), p. 56, t. v. fig. 17. 



Lyccena osias, Staudinger, Iris, ii. (1889), p. 164, t. i. fig. 4 $ . 



1 Lampides subdita, Moore, I. c. ; Butt. Ind. iii. p. 166. 



This species I distinguish hy the deep blue colour of the wings 

 above, and dark grey ground of the underside, in which it agrees 

 with L. optimus, Kheil, from Nias. The latter, however, is quite 

 distinct by the pale colour of both sexes above, and double border 

 of the fore wings in the female. Specimens from Perak agree with 

 some from Sumatra which, I think, are L. saturata of Snellen. 



Catochrysops strabo.

Catochrysops strabo, Butt. Ind. iii. p. 177. 



Lampides lithargyria, Moore, Ann. N. H. (4) xx. p. 340 ; Butt. 

 Ind. iii. p. 1/8. 



Sent from Margharita and the Karen and Naga Hills. 



I cannot see how to separate G. lithargyria, which seems to occur 

 in the same places as C strabo, though not so abundantly. 



Catochrysops pandava. 



Lyccena pandava, Horsf. Cat. Lep. E. I. Co. p. 84 (1828). 

 Catochrysops pandava, Butt. Ind. iii. p. 183. 

 Doherty sent this from Bernardmyo and Momeit only.
