180 LEPIDOPTERA INDICA. 



two closer together, discal or sub-marginal, and with an indistinct dot between the 

 costal and sub-costal 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. 



Female. Upperside, both wings much lighter than in the male. Fvrewimj with 

 the spots much larger and more numerous, there being an additional sub-apical 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 sub-median nervure in 

 front, and the third discal spot being quadi-ate with the inner and outer ends roundly 

 emarginate. Underside, both wings 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. 

 Hhulwing 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 of wings, $ ly^, % 1-yo inches. 



Allied to I. fiaiipennis, de Niceville (Journ. A. S. B. vol. liv. part 2, p. 122, pi. ii. 

 fig. 4, $ (1855), but differs in markings, and notably in the colour of the ground of the 

 underside, which is pale vandyke-brown in /. microstictum and ferruginous-ochreous in 

 /. jfavlpennis. 



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



We have not seen this species ; the types are in the Indian Museum, Calcutta ; we 

 therefore give Wood-Mason and de Niceville's description and copies of their figures.

Forewinij, vein 1 2 ends on costa opposite the end of the cell ; cell less than 

 two-thirds the length of the costa, discocellulars slightly oblique, the lower one shorter 

 than the middle ; vein 3 emitted a short distance before the lower end of the cell, 

 2 from close to 3, the base of 2 being about the same distance from 3 as 3 is from the 

 end. Costa very slightly and evenly curved, almost straight, apex sub-acute, outer 

 margin slightly convex, shorter than the hinder margin. Hindu-ing, vein 7 emitted a
