BIDUANDINJL. 189 



the wing surface suffused with dark grey. Hindwing with a large basal ring spot 

 with a dot in it and a small spot below it, an outwardly curved ante-medial series of 

 ring spots, one at the end of the cell, touching the series and also the discal series, 

 which is more or less of a similar nature, very difficult to describe ; a sub-marginal 

 series as in the forewing, a black anal spot, another in the first median interspace, 

 capped with silvery scales, and some silvery scales in the interspace between them ; 

 both wings with brown macular marks close to the margin, and brown marginal line 

 which becomes black on the lower portion of the hindwing, with a white thread inside 

 it. Antennae black, with white side dots, club with a red tip ; frons white, with a grey 

 middle stripe ; head and body above and below concolorous with the wings. 



Expanse of wings, ? l^^ inches. 



The type, a female, which is unique, is labelled Darjiliug, but we cannot 

 help thinking the locality is wrong ; nothing of the sort appears ever to have been 

 received from that locality since Hewitson described the species, though very many 

 have collected there ever since ; it probably came from somewhere in the Malay 

 Archipelago, but we keep it here on account of its Indian label.

Imago. — Male, above, violet (much richer and bluer than in B. thesmia), slightly 

 paler in the middle of the forewing, a narrow, even black border. Hindwing with two 

 sub-anal black spots bordered inwardly by an area irrorated with whitish scales ; a 

 marginal black and white line sub-anally, the cilia partly white, as well as most of the 

 tails. Below, much like B. nieliva, the markings more rufous, less fuscous, the basal spots 

 simple, not annular, the transverse discal band and the outer margin of the forewing 

 rufous-brown and ferruginous of various shades, the apical part of the outer margin of 

 the hindwing light ferruginous, the metallic green area large, extending unbroken from 

 the upper median to the internal veins, the sub-marginal line straighter, and less 

 undulated on both wings. Expanse an inch and a half, the species being larger than 

 either melisa or scudderii. Two males, Myitta. 



I name the species after Mr. Lionel de Nieeville, whose great work on Indian 

 butterflies, equally important for the information which it contains and for the impetus 

 which it is certainly destined to give to the study of insects in the East, is now in 

 progress.
