 Acontia doubledaii, Westwood, Cab. Or. Ent., p. 76, pi. xxxvii, fig. 4 (1848). 



Habitat : Nepal, Sikkim, Assam, Sylhet, Cachar, Upper Burma, Chittagong, N. India. 



Expanse: 274 to 4*5 inches. 



Description : Upperside. '* Foreiving luteous at the base, with spots and margins of 



black, the outer portion of the wing broadly black, with three rows of white markings, the 



first irregular, the second formed of elongated lunules, and the third formed of oval spots. 



HliuiwLitg, with the basal half varied with white, black, and luteous, the outer border 



broadly black, with a double row of white spots, the first larger and oval-shaped, the second 



smaller and rounded. Underside, coloured and marked as above, but rather paler." 



i_lVestzuood, 1. c. in Cab. Or. Ent.) The specimen described and figured by Westwood from its 



large size (4*5 inches in expanse) and markings is probably a female. I have not seen that sex, 



bat Mr. Otto Moller describes it from a Sikkim example in his collection as "identical with 



the male in the shape of the wing and the markings, but the fulvous colour on the forewing 



confined to the base, hardly perceptible on the hindwing, being replaced by creamy-white 



on both wings." This species was first described under the name of doubledaii, by which it 



should probably be known. 



The male has been described by Mr. Moore as follows :— " Male. Upperside : forrdjifig 

 ochreous-yellow, with spots on the basal half, and irregular lines accross the disc and along 

 exterior margin, and the apical portion of the wing broadly, black. Hindiviitg from the 

 base to disc ochreous-yellow, barred with black ; within, and spot below discoidal cell, 

 white ; rest of the wing black, with two rows of whitish spots ; abdominal margin whitish ; 

 body spotted with pale ochreous. Underside nearly as in upperside ; markings and 

 colours paler." {Moore, 1. c.) N. siva is somewliat variable in the ex'.ent and prominence of 

 all the spots and markings. It appears to be a rare species. Mr. Otto Moller has obtained 

 it in Sikkim in the Spring, Mr. Wood-Mason obtained three males in September on Nemotha, 

 Cachar, Mr. J. L. Sherwill has taken it at Jorehat, Assam, in April ; it occurs also at 

 Cheerapunji, on the Naga Hills, in Sylhet, Mr. W. Doherty has taken it in the Chittagong 

 hill tracts, and it was obtained by the Yunan expedition. 



The figure shows both sides of a male Sikkim example in the Indian Museum, Calcutta.

 "Club of rtw/iJWMt? slender, much prolongated. Palpi scaXy. Eyes nak^d. Discoidal cell 

 of both wings closed. First subcostal nervide of forewing given off after the middle of the 

 cell, the second before the end of the cell, curved downwards, the third ascending far beyond 

 the middle of the wing, curved downwards, the fourth originating soon afterwards at the 

 vertex. Disco-cdlidar nervules of the forewing carved inwardly. Second and third median 

 nervules somewhat distant from each other. Prcecostal nerviire of the hindwing curved 

 outwards, simple, ascending far behind the origin of the subcostal nervure." 



** Differs from Limenitis, under which Westwood has placed the species belonging to this 

 genus, by the closed cell of the hindwing and the position of the prscostal nervure." 

 (Felder, 1. c.) 



Several of the aberrant species of Limenitis have the cell of the hindwing distinctly 

 closed by a slender disco-cellular nervule, but in all of them the prcccostal nervure of that 

 wing is emitted opposite the origin of the subcostal nervure ; in Lebadca it is emitted a 

 considerable distance beyond that point ; the most obvious character of Lebadca is, however, 

 the shape of the forewing, it is much elongated, the apex being broadly produced and the 

 outer margin being emarginate between the upper discoidal and the first median nervules. 

 The inner margin is also very short, much shorter than the outer raavgin, whereas iu Limenitis
