148 SPOLIA ZEYLANICA. 
flight is slow, and it settles frequently at flowers, so it is easy 
to catch. I have never noticed it “ flighting.” 
I have seen a full-sized specimen killed and carried off for a 
short distance by an Asilid fly. 
180. Pariiio DEMOLEUS, De N., B., & E.; Orpheides 
erithonius, M.—Found also in Arabia, Persia, India, Burma, 
China, &c. 
It is common all over the low-country, from Galle to Jaffna, 
and occasionally joins the flights in great numbers, and may 
then be taken at the highest elevations. 
The colour seems to be much affected by the sun or age, as 
specimens of a rusty orange are very plentiful all over the 
low-country, though I have never seen one over 3,000 feet 
elevation. These specimens will almost invariably be found 
to be much worn. An extraordinary aberration captured by 
myself on the Wellawaya—Hambantota road is figured and 
described in “‘ Spolia Zeylanica,” Vol. [X., Part XX XIII. 
The larve may be found on orange and lime trees, 
and are very like those of romulus, parinda, and mooreanus, 
which are found on the same trees. According to Fryer 
(‘‘ Spolia Zeylanica,” Vol. VII., Part XXVIII.), they may be 
distinguished as follows :— 
A.—Fourth and fifth segments markedly swollen : 
a1.—Diagonal bands on segments 8 and 10 mainly brown, 
and meeting in the dorsal middle ine = mooreanus. 
61.—Diagonal bands mainly white, not meeting in middle 
line = parinda. 
B.—Fourth and fifth segments not markedly swollen : 
a2.—Candal tubercles white, much reduced = romulus. 
62.—Candal tubercles brown, size moderate = demoleus. 
181. CHarus moorEANUS; Charus helenus, M.; Charus 
helenus mooreanus, B. & E.; Papilio mooreanus, De N.— 
Peculiar to Ceylon. 
It differs from the Indian C. helenus in having a complete 
series of seven sub-discal blue lunules on the under side of the 
hind wing, but the two in interspaces 3 and 4 are sometimes 
nearly obsolete. The number of. red lunules visible on the 
upper surface of the hind wing varies from 1 to 5 in my 
specimens,
