Hulodes drylla Guenée sensu Holloway,
The species is smaller than caranea, pale buff, but with similar submarginal markings to
the female of caranea. A dark brown fascia converges with the forewing
submarginal at the apex, arising from the centre of the dorsum. The hindwing
margin is angled centrally rather than notched. Males are more strongly marked

to Burma) and this species are best treated as distinct until their
distributions in Thailand and Peninsular Malaysia are investigated in detail.
Externally, the oblique forewing fasciation in drylla is more lunulate and irregular than in donata,
where it is almost straight. In the genitalia, the uncus of drylla
slightly shorter, including the tapering apical portion beyond the dome. The
valves of drylla
the lateral triangle smaller and the apex is divided, with a narrow, tapering
process adjacent to the rounded apical part. The saccus is shorter and broader
also the aedeagus and the diverticula of its vesica. The synonymy of hilaris
noted in Nielsen et al. (1996), and the male genitalia of specimens from
Singapore and New Guinea have been compared here to bring both into synonymy
Indian H. saturnioides Guenée stat. rev. (=
Walker) is revived from synonymy with drylla.
It has a rounded, rather than angled, hindwing margin and a slightly falcate
forewing apex. The male genitalia are very much smaller than those of drylla,
the valve costa strongly curved and its ventral margin lacking an angle. The
aedeagus and the longest diverticulum of its vesica are both shorter and
range. Indian Subregion, Burma, Thailand, Sundaland, Philippines,

but only to as high as 1618m.
