128 DESCRIPTIONS OF THREE NEW ASIATIC SPECIES OF PAPILIO. 
P. Laodocus, De H. (P. Delessertii, Guér.). The upper side differs 
from the under only in having the ground colour of all the wings 
dark brown. The species is described in the work above quoted. 
PAPILIO LEUCOTHOE, Westw. 
(Plate 79, fig. 3.) 
P. alis sub-ovalibus, nigro-fuscis, anticis pone medium seriebus duabus macularum lactearum, 
internis majoribus, cuneatis (intermediis minoribus) ; alis posticis ecaudatis, lacteo-albidis 
venis margineque postico fuscis, hoc lunulis sex punctoque anali albidis. 
Expans. alar. unc. 4. 
Habitat in India Orientali (circa Pulo Penang?*) In Mus. Britann. 
Closely allied to P. Clytia + and Laodocus in the form of 
its wings and arrangement of the wing-veins (especially in the 
narrowness and length of the discoidal cell of the hind wings), 
but differs, especially from P. Laodocus, in its markings and 
colour, so that it cannot be supposed to be a suffused variety of 
that insect. Fore wings above dark brown, with cream-white 
spots ; in the discoidal cell are two minute white dots, just pre- 
ceding the insertion of the second and third branches of the median 
vein; just beyond the extremity of the discoidal cell also marked 
with three small white spots, followed by a curved row of nine 
cuneated marks of unequal size, those towards the inner margin 
being the largest, the one nearest the costa is round; the seventh 
and eighth are confluent through more than half their length, and 
the ninth or innermost one is long and lanceolate; these are 
followed by a submarginal row of eight round spots, increasing in 
size to the inner margin, the last being confluent with the patches 
preceding it. Hind wings brown, with the veins edged with, 
and the outer margin brown, the latter with six pale submarginal 
spots; those towards the anal margin being lunate, the anal angle 
itself with a small pale dot. Under surface similar, but the brown 
colour is paler, and the base of all the wings is marked with several 
small round white spots. Head and thorax black, with white 
spots; abdomen black, with a broad white longitudinal stripe 
on each side; body beneath spotted with black. 
The orchidaceous plant represented in the plate is the Trichosma 
suavis, Lindl., from the Khoseea district of India. 
* This species was obtained in a collection recently sold by auction by Mess. Stevens, of 
King Street, Covent Garden, containing specimens of Pap. Laodocus, Fulgora Delessertii, 
and F, Lathburii K. &c. 3 so that it is most probable that it was from the southern part of 
the eastern peninsula of India. 
+ Itis accordingly named after her favoured rival, Leucothoe.
