386 Wood-Mason & de Niceville — On the Bhopalocerous [No. 4, 



convex thin crescentic and a posterior triangular portion, another about 

 the same size behind and a little external to this between the first and 

 second median nervules subcrescentic in shape with its convexity 

 turned towards the base, and a third squarish external to and in front 

 of, and rather less than half the size of, this again between the second 

 and third median nervules. Underside, forewincj lighter than above, 

 the translucent spots as on the upperside ; with an indistinct submarginal 

 band of spots darker than the ground ; a dark anteciliary line ; the 

 cilia obsoletely intersected at the veins with dark ; and an indistinct 

 whifcy-brown spot touching the first median nervule and the satiny 

 patch extending from the base nearly to the outer angle and from the 

 interno-median fold to the inner margin of the wing, which bears a 

 conspicuous fringe of shite-grey setoe in part projecting straight back- 

 wards and outwards from the edge and in part turned up so as to 

 lie spread out fan-wise over the satiny-ashy patch. Hindwing darker 

 and more suffused with purple than the forewing, with a dark anteciliary 

 line, but even less distinctly intersected cilia ; with some dark mottling 

 indistinctly arranged in three bands, one subbasal and two closer 

 together discal or submarginal, and with an indistinct dot between the 

 costal and subcostal nervures, another near the end of the cell, on one 

 side only in one specimen and on both sides in the other, a third 

 between the second and third median nervules in one specimen, and a 

 fourth between the first and second in the other, all ochreous- white. 



2 . Upperside, both luings much lighter than in the male. Fore- 

 wing with the spots much larger and more numerous, there being an 

 additional subapical one, a very minute dot just in front of the third 

 median nervule, both semi-transparent, and a third opaque yellow one 

 (present in one male) touching the submedian nervure in front, and the 

 third discal spot being quadrate with the inner and outer ends roundly 

 emarginate. Underside, both ivings with the dark markings more 

 distinct than in the male. Forewing devoid of the ashy patch and fringe 

 of setae seen in the opposite sex. Hindwing with two dots behind the 

 costal nervure instead of one, one in the cell, and another between the 

 second and third median nervules on one side only so minute as to be 

 scarcely discernible. 



Expanse : ^j, 1-4; $, 1'5 inches. 



Allied to I. flavipennis, de Niceville (Journ. A. S. B., vol. liv, 

 pt. 2, p, 122, pi. ii, fig. 4, 5 (1885), but differs in markings, and notably 

 in the colour of the ground of the underside, which is pale vandyke- 

 brown in I. microstictum and ferruginous- ochreous in I . flavipennis . 



Two males, Silcuri, 25tli and 26th May, one female, Silcuri, 28th 

 May.
