nally with ochreous and whitish : secondaries more ochreous and with the markings grey 
instead of rufous brown : abdomen without a dorsal line. Expanse of wings 114 millim.

Said to be a rare species. 
Ambiilyx rubescens. (Plate CXXI. fig. 3.)

Most like the A. eos group : primaries rosy brown with cupreous-brown apical border and 
bands, the latter ill-defined, six or seven in number, four or five of which are undulated and 
cross the disc from the end of the cell to the apical border; two or three basal spots, three 
costal between the discal bands, an obUque angular apical dash and a series of dots on the 
fringe wliitish grey : secondaries dark lurid orange, the abdominal half and margin dusky ; 
abdominal and costal borders whitish ; fringe white : body purplish brown, the margins of the 
antennae, eyes, and sides of abdominal segments whitish. Primaries below dull brick-red, with 
grey external border tapering to apex and external angle and with undulated inner edge : 
secondaries paler red, whitish on abdominal border, traversed from this border to the costa by 
four equidistant slightly sinuous parallel deeper red lines : body below bright chrome-yellow ; 
palpi reddish; legs greyish white, middle and posterior tibiae reddish, posterior tarsi barred with 
reddish ; venter reddish barred with segmental grey lines at the sides ; two series of reddisli 
spots ; anal claspers reddish with white bases. Expanse of wings 75 millim. 
Mundi, an independent native state in the Plinialayas. Taken in Marcli at sugar. 
Apparently most nearly allied to A. turbata; though slightly differing in the contour of 
the secondaries, it scarcely can be regarded as a distinct genus from Ambulyx. 
The description of this species was prepared and the Plate illustrating^it printed off before 
Mr. Moore's paper was received, and thex'efore it has been necessary to retain the name written 
by him on the type-label.

Allied to BumhuUna, Moore, from Ceylon : costal vein of primaries terminating at second 
third of costal margin ; subcostal quinqneramose ; the first branch emitted from outer third 
of the main vein and reaching the costal margin just beyond the costal vein ; second branch 
emitted just before the end of the cell and terminating near to the apex ; third and fourth 
branches emitted fi-om a long footstalk at the upper angle of the cell ; fifth branch emitted 
close to the latter; discocellulars strongly angulated ; upper radial emitted from a little
