Show 1891.] THE NAGA AND KAREN HILLS AND PERAK. 277 LIMENITIS DANAVA. L. danava, Moore, Cat. E. I. C. p. 180, t. vi. a. 2 ; Butt. Iud. ii. p. 157. Less common than the last two in the Naj:a Hills; a female from there is darker in colour than others from Sikkim and Landour. ATHYMA KANWA. A. kanwa, Moore, P. Z. S. 1858, p. 17, t. Ii. fig. 2 ; Butt. Ind. ii. p. 169. Several males of this were taken in the Karen Hills at 4000-5000 feet. ATHYMA PRAVARA. A pravara, Moore, Cat. E. I. C. p. 173, t. v. «. 4; Butt. Ind. ii. p. 170. Sent by Doherty from Margharita and the Karen Hills. ATHYMA MAHESA, var. RANGA. A. ranga, Moore, Cat. E. I. C. p. 175, t. v. a. 6 ; Butt. Iud. ii. p. 172. A single specimen of this, which I consider to be a form of mahesa, taken in March in the Karen Hills. ATHYMA OPALINA, var. ORIENTALIS. A. orientalis, Elwes, Trans. Ent. Soc. 1888, p. 354, t. ix. fig. 4 J . Males of this from the Naga Hills are exactly like those from Sikkim, Bhutan, and Khasia, which I called orientalis, but two from the Karen Hills are nearer to the typical opalina. This inclines me to think that the race is not so constant as I supposed, and I therefore drop the name as a specific one. NKUROSIGMA DOUBLEDAYI, var. ? (Plate XXVII. fig. 7,6 •) Acontia doubledaii, Westw. Cab. Or. Ent. D. 76, t. xxxvii. 4 9 (1848). Adoliassiva, Westw. Gen. D. Lep. ii. p. 291 (1850). Neurosigma siva, Butt. Ind. ii. p. 151, t. xix. fig. 80 6 • Seems common in the Karen Hills at 4000-5000 feet; but males only were sent. These are perfectly distinct from the same sex of the form found in Sikkim, Bhutan, and Khasia, having the rufous colour confined to the base of the fore wing only, and not spread over the greater part of the fore and inner half of the hind wing as in Sikkim. In fact they resemble Westwood's figure, which represents a female from the Khasia Hills, except in the absence of a yellow dash near the base of the hind wing. I have a specimen collected by Doherty iu the Chittagong Hills, which is like the Sikkim form. If, therefore, the female from the Karen Hills proves different from the Sikkim and Khasia one, I should have no hesitation in naming this form as distinct; at present, however, we may only have a case |
