acutely-sinuated than in Wet form of Pyranthe ; the discocellular spot small, slender, 
j Rindwing with, or without, a minute point at tip of the veins. Underside. Forewing 
with the anterior half, and the entire hindwing pale olivescent-yellow, crossed 
between the veins by numerous pale greyish-ochreous strigae. Both wings with a 
slightly-apparent small pale reddish discocellular spot. Posterior half of fonnving 
bluish-white ; veins of hindwing basally whitish. 
Female. Upperside bluish-white. Forewing with the costal border from base 
black scaled, merging into the black apical marginal band, which is broader than in 
female Dry form of Pyranthe , having its upper portion to middle median veinlet 
entirely black, and including the subapical lunules which are present in the latter 
species; discocellular spot larger. Rindwing with a narrow, more or less macular, 
marginal band. Underside brighter yellow than in male, the strigae more distinct, 
the submarginal lunular fascia slightly apparent. Forewing with the discocellular 
spot more distinct ; the hindwing with two small pale-centred discocellular spots, and 
a similar spot within upper end of the cell. 
Expanse, c? 2^, ? 2^ 0 to 2 x - 0 inches. 
Dry form . Male. Upperside similar to Wet form. Forewing with the dis¬ 
cocellular spot more distinct. Himdwing with slightly-apparent marginal narrow 
blackish-scaled spots. Underside similar to Wet form. Both wings with a more or 
less distinct small pale-centred reddish discocellular spot. 
Female. Upperside bluish-white. Foreiving with the marginal band as in Wet 
form, the anterior portion not having any subapical whitish interspaces; some 
specimens also show traces of black-scaled lunules from the middle median veinlet 
to the submedian vein; discocellular spot prominent. Hindwing with a black, broad 
marginal continuous band, and two or three inner upper-submarginal, less distinct 
partly-confluent lunules. Underside brighter yellow, the strigse more apparent, 
the discocellular spots more distinct, and the submarginal lunular fascia more 
apparent. 
Expanse, <$ ?, 2f- 0 to 2^ inches. 
Habitat. —Ceylon?; Mergui, S. Tenasserim; Malay Peninsula; Penang; Sumatra; 
Billitong; Philippines. 
Distribution. —We possess a male from Capt. Hutchison, reputed to be from 
Ceylon (vide Lep. Ceylon, i. pi. 48, fig. 3); also both sexes from Mergui, taken by 
Dr. J. Anderson, and others from Malay Peninsula, Sumatra, and Billitong. 
Of our illustration on Plate 578, figs. 1, la, b, S ? are from Mergui specimens.
