COLIIN^. 85 



TFei/orjn. (figs. 1, la, c??). Male. Upperside, Both wings white, the basal 

 areas sulphur-yellow. Foreiving with the costal edge anteriorly, and the exterior 

 margin slenderly black bordered, the inner edge of the border being slightly 

 sinuous at the apex. Underside pale yellow. Foreiving with the lower discal area 

 white. Hindwing sometimes with a slightly-defined small ochreous streak on upper 

 discocellular veinlet. Foreiving beneath with an elongated brush-like tuft of long, 

 fine silky hairs, extending along the edge of the posterior margin, from base to near 

 half its length, this tuft being either recumbent and flattened, along the margin, 

 or, it is sometimes exserted and outspread, and is then projected along the upperside 

 of the wing in its entire length. Hindwing above with a conspicuous elongated- 

 oval raised patch of glandular scales extending above the subcostal vein to its first 

 branch, this patch being visibly opaque on holding the wing up to the light. 



Female. Both wings with the basal yellow tint more widely extended, and 

 sometimes pervades the entire wing. Foreiving with the black costal band extending 

 broadly from near the base to upper end of the cell, where it is more or less 

 confluent with a round black discocellular spot, from whence it runs outwardly 

 more narrowly, then widening apically, and continues sinuously down the exterior 

 margin to posterior angle, the anterior portion being subapicaliy traversed by three 

 or four white spots, and lower disconnected inwardly-oblique sinuous black streaks. 

 Hindiving with a broad sinuous-edged continuous black baud. Underside similar to 

 the male. Antennse in both sexes greyish-black above, pinkish-grey below. 



Expanse, c? ? 2 1*0 to 3 inches. 



Intermediate or Extreme Wet form (fig. 1, c, d, ?). Female. Upperside. Both 

 wings either very faintly yellow-tinted basally, or white throughout. Foreiving 

 with the extreme base sometimes grey-tinted ; with broader subbasal-costal black 

 band and its continuous discocellular patch, apical and marginal band enclosing its 

 subapical white spots, the sinuous or sometimes diagonal marks below the latter 

 extending to the lower median interspace. Hindiving with a broad marginal band, 

 and more or less defined confluent submarginal diffused lunules. Underside 

 similar to Ordinary Wet female. 



Expanse, ? 2i7) to 3 inches. 



Ordinary Dry form {&g. le, i, c??). Male. Upperside. Both wings with the 

 basal yellow tint more restricted than in ordinary Wet form. Foreiving with the 

 outer marginal band more or less slightly macular posteriorly. Underside more 

 uniformly paler than in Wet form. Foretving with a lower discocellular nacreous- 

 centred red spot, a very indistinctly-defined reddish transverse subapical inwardly- 

 oblique narrow sinuous fascia, and a slight fascia bordering the apex of wino-. 

 Hindwing with a similar lower discocellular nacreous spot, which is outwardly ringed 

 by a slender red line, and is accompanied by a smaller more or less defined similar
