1886.] Lepidoptera of Gachar. 391 



245. Plesioneura monteithi, n. sp., PI. XVIII, Figs. 3, 3a, $ . 



^ . Upperside, both wings rich dark brown with a vinous tinge 

 in some lights. Forewing with a semi-transparent white lustrous disca 

 band of four completely-conjugated spots, the first large and oblong 

 at the end of the cell ; the second posterior and external to it at the 

 base of the interspace between the second and third median nervules, 

 and consequently wedge-shaped ; the third conterminous with the first 

 and second, forming an oblong figure whose opposite angles are sub- 

 equal, and placed in the interspace between the first and second median 

 nervules ; and the fourth subpentagonal, double the size of the second, 

 and half the size of the first and third, but not extending for more than 

 two- thirds of the distance across the sub median area in which it is 

 placed. Hindwing unmarked. Underside, /orewm^ marked as above, but 

 with the three subcostal streaks which connect the band with the costa 

 much more distinct than above, where they are all but imperceptible ; the 

 lowest spot of the discal band much larger, reaching the submedian 

 nervure, and outwardly diffused. Cilia concolorous with the wings. 



Expanse : 1*7 inches. 



Two females, Irangmara, 8th and 18th July. Closely allied to 

 P. feisthamelii, JBoisduval, from the Moluccas. 



246. COLADENIA ANDAMANICA. 



Plesioneura dan, var. andamanica, Wood-Mason and de Niceville, Jonm. A. S. 

 B., vol. 1, pt. 2, p. 257, n. 118 (1881). 



One specimen in forest near Silcuri, 8th August, which agrees best 

 with this species, but differs in the discal golden band on the upperside of 

 the forewing being slightly broader and the yellow spots on the underside 

 of the hindwing obsolete. It agrees with the P. dhanada of Moore (Proc. 

 Zool. Soc. Lend., 1865, p. 789, from Masuri in the Western Himalayas) in 

 the golden band not nearly reaching the anal angle of the forewing on the 

 upperside (thereby differing from P. (Kerana apud Distant) aurivittafa, 

 Moore, Proc. Zool. Soc Lond., 1878, p. 843, pi. liii, fig. 2), departing 

 from it in having the cilia cinereous throughout. 



247. COLADENIA DAN. 

 Papilio dan, Fabricius, Mant. Ins., vol. ii, p. 88, n. 798 (1787). 



Eleven specimens of both sexes from 22nd to 30th May. 



248. Abaratha sura. 



Achlyodes sura, Moore, Proc. Zool. Soc. Lond., 1865, p. 786. 

 Two males, Irangmara, 21st July and 2nd August.
