LEPIDOPTERA INPICA. 
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. 
Foreiving 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. 
Expanse, S ? 2p- 0 to 2^ inches. 
Dry-season Brood.

Upperside. Forewing with the black outer marginal band showing a much less- 
defined series of white streaks, which are either slender or obsolescent. Hind wing 
with very slightly-defined outer marginal vein-points. Underside. Foreiving with 
the apical area very faintly yellow tinged, the inner-edge of the marginal band being 
very obscurely indicated. Hindwing very faintly yellow tinged, the medial fascia only 
being very slightly indicated. 
Female. Upperside. Foreiving with somewhat narrower black markings than 
in the intermediate form ; the connection from the cell to the outer band much 
narrower, and in some almost obsolete, the white slender streaks on the outer band 
less defined or obsolescent. Hindwing 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. Hindnving as in the male.

Habitat. —Upper and Lower Bengal; Assam ; Lower Sikkim; Burma; 
Tenasserim ; Siam; Tonkin. 
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 Niceville (J. As. Soc. Bengal, 1885, p. 50) writes, “I have seen a 
single male specimen of Zelmira taken in Calcutta.” Mr. W. S. Atkinson, in his 
MS. Notes, says it is “ common in the plains of Bengal. Also taken at Dacca and 
Silket.” Col. C. 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
