1865. ] FROM THE NORTH-WEST HIMALAYAS. 487 
Allied to P. agestor, and figured as such by Kollar, but differs 
from that species in being somewhat smaller. Markings similar, but 
grey instead of a slaty colour, those on the disk of the hind wing 
being defined by three graduating series of pale spots, the interspaces 
being black. Exp. 3} inches. 
Hab. N.W. Himalayas. 
Note.—‘‘ Appears rare, as I have only taken two specimens, both 
in identically the same spot, in April, at Kussowlie, on the first range 
of the Himalayas, 6000 feet altitude. Each of these individuals 
affected a high spray of bramble, whence it dashed off for a rapid 
soar for a short distance, returning to its post.”

Rare in the N.W. Himalayas, and at low elevations.

Rare in the N.W. Himalayas, and at low elevations.

pt. 2. tab. 1. 
Abundant about springs, rivulets, and on the damp sandy margins 
of larger streams in all parts of the N.W. Himalayas, at least as far 
as the crossing of the Sutlej at Wangtoo; but as we approach the 
bleaker Tibetan uplands it disappears. Larva feeds on Yanthoxrylon 
hostile. 
6. PaprLio ERITHONIUS, Cramer, Pap. iii. t. 232. f. A, B. 
This is constant to the Aurantiaceze, mountains and plains. 
7. PariLio MACHAON, Linn. 
Abundant in the N.W. Himalayas, on grassy downs and slopes, 
from 6000 to 10,000 feet altitude. 
8. PapiLio SARPEDON, Linn. (Cramer, Pap. t. 122. f. D, E). 
Seen but in few places, and never more than one at a time. It is 
bold and rapid in flight, and not easily captured. 
9. ParPILio CLOANTHUS, Westwood, Arc. Ent. pl. 11. f. 2. 
Equally rare with P. sarpedon, affecting the same localities, and 
can hardly be distinguished from it when on the wing. Both species 
taken sitting with closed wings by the moist margins of a trickling 
rill, Altitude 5000 to 7000 feet, N.W. Himalayas. 
10. Paprtio PROTENOR, Cramer, Pap. t. 49. f. A, B. 
A considerable number seen together, floating and flapping their 
wings lazily and then settling on the blossoms, in waste marshy 
ground overgrown with Compositz (thistles). I have also seen a 
number congregated with P. polyctor on the damp sandy margins of
