This species is mentioned by Mr. F. Moore in his " Lepidoptera of Ceylon," but 

 he gives no exact details of tlie localities where it is to be met with in that island. 

 In the British Museum there are some specimens from Ceylon, one of which is said to 

 be from the neighbourhood of Colombo. 



Mr. De Niceville in his paper on the " Butterflies of Ceylon " (Journ. A. S. 

 Bengal, vol. l.Kviii. pt. 2, p. 214, 1899) writes : "Mr. Pole says that it is not found 

 south of Puttalam, nor along tlie coast as far as Trincomali, as far as he is aware. It 

 flies in June and December, has apparentl}' two l^roods, is a very local species, and is 

 a lover of the sun, even on wind-blown and arid sea-shores. It occurs also in South 

 India. Its transformations are unknown." 



From the Nilghiri Hills T. euchark is recorded both by Sir George Hampson and 

 the late Capt. E. Y. Watson. They both agree that T. cKcharis is the "dry-season " 

 form, T. pseudevanthe the "wet-season" form; and Capt. Watson considers T. fitea 

 to lie " intermediate." Sir George Hampson writes : " The genera Callosune and 

 Idmais frequent the plains at the base of the Nilghiris, and only appear on the plateau 

 as stragglers." 



Captain Watson also records T. eiicJiaris from Mysore. (Cf Journ. Bombay Nat. 

 Hist. Soc. vol. V. p. .36, No. 107, 1890.) 



Colonel Swinhoe obtained it at Belgaum in September and in Bombay in the 

 months of February and December, where it was "very plentiful." (Cf P. Z. S. 

 1885, p. 144.) 



Mr. J. Davidson has kindly given me the following notes : " I have reared 

 T. euclaris in Bijapur only. The larva is narrow, and much resembles that of a 

 moth. It is of a dull green, with no line along the back, but with either a yellow or 

 pinkish-white line along each side. It has an extraordinary habit of resting with the 

 anal seirment turned up and not resting on a twig. The pupa was very much bent 

 back, far more so than Tcria-s. and the head was prolonged into a long thin beak 

 recurved. When first formed it is pale green, but becomes a greyish-white, marbled 

 more or less with brown. The larva feeds ou Cnndaha iiidica." 



Dr. Butler writes : " The seasonal forms of this species follow the usual rules ; the 

 wet-season forms being heavily marked above, yellowish and white with the usual 

 markings below ; the intermediate forms are similar above, but the females show 

 more orange in the apical black patch ; the dry-season forms are more lightl}' marked 

 above, and much more rosy and more strongly striated below. Of each form there are 

 two phases, one showing a double bar on the under surface of the male secondaries, 

 the other only showing a costal dash or dot. Of the double-barred type are, first,
