146 BUTTERFLIES, 



at Sivoke in March. Found also in Western and Central China 

 according to Mr. Leech, but the specimen he figures as S. asthala is a 

 typical male of S. hippoclus^ Cramer. 



223. Cyrestis thyodamas, Bolsduval. 



Occurs commonly from March to December up to about 6,000 feet. 

 It is found in Western China, Japan, and in the Loochoo Islands. The 

 larva is a queer object; it has two long horns on the head, a still larger 

 one on the middle of the back (on the fifth segment), and a similar one 

 on the twelfth segment. The pupa has two very long processes pro- 

 jecting forwards from the head and slightly upwardly curved containing 

 the palpi, which remind one of the long "snout" of the imagines of 

 the genus Libytlica. The larva feeds on the leaves of various kinds of 

 figs [Ficus indica, Linn., F. ncmoralis, Y^alL, &c.) 



224. Cyrestis cocles, Fabricius. 



Extremely rare in Sikhim, which is probably the westernmost 

 limit of its range. Single specimens have been taken at Singla and 

 Sivoke, at low elevations, in the spring and autumn. The difference 

 in coloration observed in this species may be due to seasonal causes. 

 Mr. Dudgeon has observed that the green form occurs in March, and 

 the brown one in August and September. 



225. Cyrestis (Chersonesia) risa, Doubleday and Hewitson. 

 Occurs somewhat commonly at low elevations throughout the 



warm months of the year. 



226. Kallima inachds, Boisduval. 



Common at low elevations from March to November. It is 

 found also in Western and Central China. When frightened it in- 

 variably settles, as far as I have noticed, with closed wings on a 

 twig or branch. It sometimes, as Elwes points out, settles with open 

 wings, but on these occasions it has, I feel sure, no thought of enemies. 

 It is particularly fond of the juice from the bark of certain trees, 

 and eagerly sips up the "sugar" of moth collectors. Stale beer, 

 also old beer casks, are an irresistible attraction to these butterflies. 

 Mr. G. C. Dudgeon has bred the larva in Bhutan on a common 

 blue-flowered plant named Strohilanthos cajntatns, T. Anderson. It 

 may be interesting to note that while the Sumatran and Javan species 

 of Eallima have yellow-banded males and bluish-white-bandcd females, 

 the Bornean species is yellow-banded in both sexes like K. inachus. 



227. Kallima knyvettii, de Nic(5ville. 



Brought from near Buxa in Bhutan year after year, but never 

 in large numbers, by native collectors. Mr. Elwes records it from 

 the Naga Hills at about 5,000 feet.
