and fresh examples were observed in February. The flight is strong, undulating, 
and very erratic, and it is by no means easy to secure in good condition. The larva 
is found not rarely on the leaves of various Aurantiacese ” (Tr. Ent. Soc. 1895, 469).

Imago. —Male and female differs from C . Helenus in the shorter and more 
triangular form of the forewings. Male. Upperside. Hinclwing with the three 
portions of the upper discal creamy-white patch much wider, the upper portion 
being twice the width of that in Helenus, the lower portion extending to the 
discocellular veinlet, and generally also along its edge within the cell, the lower por¬ 
tion also having a cluster of greyish-white scales decreasingly extending to near the 
lower median veinlet; anal and the submarginal red lunules similar, the anal with 
an upper bordering of blue scales. Underside. 'Forewing with the greyish-white 
outer vein-streaks shorter than in Helenus, crossing the discal area midway between 
end of the cell and the exterior margin. Hindwing with the discal white patch 
wider; and generally there are two lower-discal additional red lunules present 
between the subanal and the white patch. 
Female. Upperside somewhat paler than in the male. Underside also paler. 
Forewing with the pale vein-streaks inwardly more distinct. Hindwing similar to the 
male.

Distribution, etc.— “This butterfly may be met with in the Kanara District of 
Bombay, wherever the country is sufficiently wooded, in the same situations as 
Folymnestor , and at any time of the year, but is not nearly so numerous” (Davidson 
and Aitken, J. Bombay N. H. S. 1896, 580). “ We got one larva of this butterfly on 
the Tirphal ( Zantlioxylum Flietsa ), a horribly thorny tree, leafless in the dry season. 
The larva has the 4th and 5th. segments even more tumid than in Folymnestor, 
forming a broad and high hump, nearly flat on the top, and bounded before and 
behind by rugged ridges of a whitish or pale grey colour, chequered with fine brown
