pale yellow ; base of costa pale yellow ; veins not lined, the subcostal and medial 

 fascia only being very slightly apparent. 



Female. Upperside similar to same sex of wet form, but with the dark markings 

 less prominent, the white portions being either clear or faintly flushed with very pale 

 yellow. Underside with paler and much less defined markings than in wet form. 

 Forewing with paler yellowish-tinted apex. Hindwing with the veins clear or 

 obsolescently lined, the subcostal and medial fascia slightly apparent, the costal and 

 outer border and medial facia paler than in wet form ; base of costal edge bright 

 yellow.

Upperside. Foretoing with the black outer mai'ginal band showing a much less- 

 defined series of white streaks, which are either slender or obsolescent. Hindwing 

 with very slightly-defined outer marginal vein-points. Underside. Forewing with 

 the apical area very faintly yellow tinged, the inner-edge of the marginal band being 

 very obscurely indicated. Hindiving very faintly yellow tinged, the medial fascia only 

 being very slightly indicated. 



Female. Upperside. Foreioing with somewhat narrower black markings than 

 in the intermediate form ; the connection from the cell to the outer baud much 

 narrower, and in some almost obsolete, the white slender streaks on the outer band 

 less defined or obsolescent. Eindwing with an outer-marginal row of blackish spots 

 of more or less small size, and a few dusky scales very faintly indicating the discal 

 fascia, or in specimens of the extreme dry form, this wing is entirely unmarked. 

 Underside. Forewing with similar but paler-defined markings as in the intermediate 

 form, the connecting streak from the cell narrower, the apex tinged with very pale 

 yellow. Hindwing as in the male.

Distribution. — Cramer gives "Coromandel" for the locality of his Zelmira, 

 fig. C, D, which is doubtless erroneous, as our present species does not occur so far 

 south. Mr. L. de Mceville (J. As. Soc. Beugal, 1885, p. 50) writes, "I have seen a 

 single male specimen of Zelmira taken iu Calcutta." Mr. W. S. Atkinson, in his 

 MS. Notes, says it is " common in the plains of Bengal. Also taken at Dacca and 

 Silhet." Col. 0. Swinhoe's types of Olferna and Irvinii were both taken at Maldah, 

 Upper Bengal, by Mr. N. Irvine, in March, April, and May — which we have verified 

 by the type labels and reference to the describer's register. Col. Swinhoe records it
