186 LEPIDOPTERA INDICA. 



margin it is white. Underside. Forewing with the ground colour dull pale greyish- 

 orange, the apex and lower basal portions of the wing darkly and the outer middle 

 portion of the wing lightly suffused with smoky-brown ; a sub-basal brown bar in the 

 cell, another at its middle, the lower portion of each attached to the dark basal 

 suffusion, a brown bar at the end, a discal even band, with sinuous edges, from the 

 costa, passing close outside the cell-end bar, dark in the apical suffusion, pale hindwards 

 and ending diflfusedly before reaching the hinder margin, a sub-marginal line of brown 

 lunules, well separated from the margin. Hindioing milky white, a brown basal spot, 

 another some way beneath it, close to the abdominal margin, followed by three larger 

 brown spots in an oblique line, the middle one the smallest, the outer marks all white, 

 indicated by their brown edges, consisting of a bar at the end of the cell, and a discal, 

 irregular band which curves inwards at its lower end in a blunt W-shaped form to the 

 abdominal margin, a series of thin brown, sub-marginal, lunular marks, a small black 

 anal spot, a larger one in the first median interspace, both capped with blue scales, and 

 a few blue scales between them, terminal line black. Antennae black, with white dots 

 beneath, club with a red tip ; frons blackish-brown, with a white line on each side ; head 

 and body above and below concolorous with the wings. 



Female. Upperside rufous-brown. Forewing with a very large orange-red band 

 in the disc, which occupies nearly a third of the surface of the wing, this band varies 

 in extent somewhat in difi"erent examples, and in all that we have seen from Mergui 

 extends from near the costa to near the hinder margin, Hindwing paler than in the male, 

 and so is the underside of both wings, but otherwise they do not differ from the male. 



Expanse of wings, ^ $ Ijq- to 1^ inches. 



Habitat. — Mergui, Burma. 



Distribution. — Both sexes are in our collection from Mergui and the Donat Range, 

 Tenasserim ; it may be merely a local form of B. tliesmia, Fabricius, of which we have 

 many examples of both sexes from 'the Malay Archipelago, but the females of thesmia 

 are very differently coloured on the upperside, and the ground colour of both sexes 

 and the bands and spots on the underside, though similarly disposed, are always very 

 much darker in thesmia, and therefore we feel obliged to keep fabricii as a distinct 

 local form.
