96 Dr. G. B. Longstaff’s Notes on the Butterflies 
addition two moths, an Arctiid, Lewcoma submarginata, 
Walk., and a Nyctemerid, the fuscous-and-white Zonosoma 
eenis, Cram. (= interlectwm, Walk.), the former possibly, 
the latter certainly a day-flyer. 
At last I dragged myself away and an hour later reached 
a most attractive flowery bank immediately above the 
river. This was evidently a great place, for in a very short 
time I secured two sadly battered Papilio memnon, L., of the 
form agenor, L.; a large male Jxzias pyrene with the fore- 
wings almost symmetrically bitten near the tip of the costa ; 
also an insect that I had greatly desired to take, the lovely 
and delicate-looking “ map-butterfly,’ Cyvrestis thyodamas, 
Bdv., in splendid condition. This, a Nymphalid, by the 
possession of a well-marked anal lobe to the hind-wing 
suggested the Rapala group of Lycenids, but a close 
examination of the veins shows that neither lobe nor tail 
is homologous in the two widely separated genera. In ad- 
dition to the above I took a second Caduga tytia, Gray, the 
first having been netted 1000 feet higher. This blue-and- 
black Danaid is distinguished by having brown hind-wings. 
Time was however getting on and my “sais” was waiting 
with the pony by the little bridge, so I reluctantly mounted. 
T had not ridden far when I caught a glimpse of Kallima 
inachis, Bdv., flying by the roadside ; flinging myself out of 
the saddle I was fortunate in netting the butterfly of all 
others that I had wished to see alive. It proved to be a fine 
female; I could not afford to risk waiting to see her settle, 
and alas! never saw another. A few minutes later my 
sais brought me a damaged Huplea with a lovely purple 
gloss; seeing many about I foolishly did not keep it. 
These things happened close to the Tista bridge, by which 
the road to Lhasa crosses the river, here only some 650 feet 
above the sea, so deeply are these Himalayan valleys cut 
down. Sad to say in a few minutes the winding of the 
road took me under the deep chill shadow of the mountain 
and the purple-glossed Huplwas and nearly all the other 
butterflies vanished for that day. A solitary Neptis aceris, 
Cr., together with a few Lvias pyrene, Huphina nerissa and 
Lampides elpis, were all that I saw; with them was a 
Nyctemerid day-flying moth, 7vypheromera plagifera, Wk. 
The rest-house at Riang was reached too late for any more 
collecting, and I had to content myself with watching the 
long trains of Colonel Younghusband’s bullock wagons 
painfully dragging loads of compressed hay for the Tibetan
