a List of the Butterflies of Hong-Kong. 449 
18. Melanitis leda. 
Papilio leda, Linn., Syst. Nat,, i., 2, p. 773 (17G7) 
[forma sest.). 
Pap. ismene, Cram., Pap. Exot., i., t. xxvi., figg. A. B. 
(1775) {forma liyem.). 
A common butterfly in Hong-Kong, frequenting dark, 
sliady places and settling on the ground among dead 
leaves, where its sombre colours effectually conceal it; 
towards evening it comes out and flies wildly about in 
the open and along roadsides. Extremely variable in 
size and markings ; the specimens from a valley about a 
mile and a half east of Victoria, wht-re the soil is strongly 
charged with oxide of iron, are remarkable for the rich 
reddish-ochreous tint of the underside of the wings. All 
the winter specimens which I have seen are of the form 
ismene, Cramer; the typical form leda, Linn., with well- 
marked ocelli on the underside, appearing with the rains 
in April and May. 
19. Melanitis aswa. 
Papilio leda. Linn., Syst. Nat., i., 2, p. 773 (1767). 
Yar. a. Cyllo tristis, Feld., Reise Nov., Lep., iii., p. 464, 
n. 785 (1867). 
Cyllo aswa, Moore, P. Z. S., 1865, p. 769. 
I have seen only one example of this well-marked 
form, taken at Kowloon by Mr. S. B. J. Skertchly 
late in 1891. 
20. Discophora tullia. 
Papilio tullia, Cram., Pap. Exot., i., t. 81, figg. A. B. 
(1779). 
Not very common ; usually seen flying along roadsides 
at dusk, and disturbed from shady places during the day. 
The ? appears to be more common than the $ . First 
taken 31st December, 1891, and sporadically up to May.
