DESCRIPTION.—"Anterior wings elongate, falcate, acuminate, of bright light fulvous, the base and
anterior portion of the costa more obscure, the costa from the middle to the apex and exterior margin
deep brown, mt h fulvous spots at the apex and anal angle ; a sigmoid spot in the cell and a larger spot
on the disco-celhdar nervure of the same colom- as the margin. Posterior wings elongate, dentate,
caudate, hght fulvous at the base, deep fuscous brown beyond; a series of five lunulate light fulvous
spots near- the outer margin, preceded by three spots and a striga of a deeper fulvous near the anal
angle, the tail fulvous brown, paler towards the apex, Ciha marked with pale fulvous near the outer
angle. Beloiv the wings are bright yellow ochre coloured, the anterior with several irregular spots in the
cell, a larger one on the discoidal, three on the costa near the apex, a fourth below the last of these^
followed by a zigzag line, and the outer margin light brown; the margin is marked with lighter
coloured clouds, and preceded by some indistinct spots on the nerviu-es more or less confounded with
it. The posterior wings have four brown spots at the base, a broad band beyond the middle of deep
rieli brown, extending along the abdominal margin to the tails, which are brown. Tliis band is marked
anteriorly between the nervules with silvery atoms, those nearest the inner margin forming a silvery
lunule. Beyond the band the wings are of the same coloiu' as at the base, with four sigmoid spots, a
narrow line on the margin itself, and the cilia at tlie ends of the ner^ailes rich brown. Head and
antennoe brown. Thorax bright shining black, covered at the sides with brown hair- and scales, apparently
natm-ally almost bare on the disc ; abdomen very pointed, luteo-fulvous." DOUBLEDAY, 1. c.
"Female much larger than the male, the wings expanding inch more; fore wings less falcate,
their colour above much paler, base not shaded with fuscous : the spot on the disco-ceUular nervule is
more distinct; there arc two or three irregular dark spots in the cell; the dark border is narrower and
not quite of so deep a colour; tlie light fulvous spots are more distinct, the posterior wings paler, with
tlie dark margin nmch narrower; the inner row of spots very distinct, the indentations and tail pale
fulvous, and the under surfacc is nnich paler." (Doubleday, 1. c., aud Gen. Dim-n. Lepid. pi. 2).
Mr. Edward Doubleday considers this species as distinct from Papiho Payeni (Van der Hoeven), on
account of its larger size and from the hind wings not being dentate, and in the broad deep-brown baud
below. From the identity, liowever, of their characteristic markings, I cannot but think that the two
