PAFILIONIN^. 17 



costal-end of the band with a black patch crossed by a crimson slender sinuous 

 streak, and its lower outer-end from within apex of the cell to anal angle bordered 

 with black patches crossed by crimson lunules ; abdominal margin with a grey 

 streak, and in the male with a pale ochreous woolly-patch ; cilia from upper median 

 to anal angle slenderly alternated with white. Body above greyish-black, beneath 

 and legs greyish ; antennae black. 



Expanse, 3^ to 4 inches. 



Laeva. — " Full-fed 1|- inch long. Head and neck contractile ; body widest at 

 the fifth segment, from which it tapers gradually to the anal segment ; the ridge 

 over the head is furnished with two tubercles, black in front, white posteriorly ; the 

 fifth segment has a yellow bar which projects on each side beyond the body, and has 

 the appearance of a yoke, the points of this yoke are black. Colour green ; the 

 thirteenth segment is of a pale transparent blue-green ; a pale yellow subdorsal line, 

 and an almost white spiracular line are the only markings; head greeDish-yellow ; 

 legs, claspers, and abdomen blue-green ; the thirteenth segment terminates in two 

 sharp points which join at the end, so that the division between them is apparent 

 only on close examination" (Mrs. S. llobson, Journ. Bombay N. H. Soc. 1895, 

 497). 



Pupa. — Conical ; truncated in front ; head slightly cleft in front ; thorax angled 

 in front and at the sides, and with a short dorsal frontal projected process. Colour 

 pale green, with a lateral and a divaricated pale yellow dorsal line. 



Habitat. — North "Western, Central, and Eastern Himalayas; Assam; Burma; 

 Shan States ; ? Malay Peninsula. 



Distribution, Habits, etc. — We have a male from Kashmir, taken by the late 

 Capt. R. Bayne Reed. Capt. T. Hutton records it as " very common, at Masuri, in 

 fine warm weather, flitting with great rapidity over the tops of the loftiest trees. 

 It usually selects some lofty Oak, over the summit of which it continues to dance 

 with a jerking flight, like that of P. Sarpedon, until its domain is invaded by another 

 individual, when a rapid chase round and round the tree takes place, one- while they 

 dart away from the tree down the side of the steep mountain, but ever and anon 

 return to the favourite tree, until one is fairly driven off, when the other resumes its 

 dance as before. It is diflficult to capture, from its high and rapid flight. It 

 appears at the end of April, and continues throughout ttie summer " (Tr. Ent. 

 Soc. J847, 51). Capt. A. M. Lang says it is "equally rare with P. Sarpedon, 

 affecting the same localities in the N.W. Himalaya, at altitudes from 5,000 to 7,000 

 feet. I have taken both the species, sitting with closed wings by the moist margins 

 of a trickling rill" (Ent. Mo. Mag. 1864, 101). Major J. W. Yerbury obtained it 

 at " Murree in August and September" (P. Z. S. 1886, 376). Mrs. S. Robson found 

 the larva at Masuri, in June, on a large and common tree, Machilus odoratissima "
