li7. Catopsilia crocale, Cramer, 



Mooi'e as 0. crocale and G. catilla, Cr.amer, bafc the former is the 

 older name. It is a vory variable species, which does not ap|)ear to he 

 dependant on the seasons for its various forms. It is very widely 

 distrihnted in India, Malaya and Australasia, and seems to be varial)le 

 wherever it is found. It is largely given to inigrating- in Ceylon and 

 Sonthern India, and again in Java. Its larva feeds on Cassia. 



148. Catopsilia pyranthk, Linnseus. 



Moore in Lep. Cey. gives four forms of this species as separate 

 species, G. gnoma, Fabricins, 0. ilea, Fabriciiis, G. chri/seis, Druiy, as 

 well as typical G. 'pyrantlie. Mauders notes tliat as fai' as his observa- 

 tions go these four forms are not dependent on season, but appear 

 indiscriminately nearly throughout the year, those flying in tlie dry- 

 season from February to April being a little smaller than those found 

 during the rest of the year. G. chryseis is perhaps not as common a 

 form as the others. It takes part in the low country flights. It occurs 

 everywhere in India and Malaya, the larva feeding on Gassia. 



J49. Tertas libythea, Fabricius. 



Moore as T. dwua, Horsfield. Dr. Butler considei'S that T. senna 

 and T. leina, both of Felder, represent the wet-season form of this species, 

 T. drona is a form intermediate between the dry and wet-season forms, 

 and the dry-season form is true T. libythea, with T. rubella, Wallace, 

 and T. hainana, Moore, as synomyras. In Ceylon it is conmion in open 

 country between 2,000 and 5,000 feet. It lias a very w^ide range in the 

 East. Like all the rest of the genus, the larva feeds on the Leguminosse. 



150. Terias venata, Moore. 



Moore as T. citignla, Moore, and T. rama, Moore. Dr. Butler omits 

 the former species from his " A Revision of the Fierine Butterflies of 

 the genus Terias from the Old World." (Ann. and Mag. of Nat. Hist., 

 seventh series, vol. i, p. 64, n. 21 (1898). He gives the range of 

 r. -ye^ia^a " From the Himalayas southwards to Ceylon, and probably 

 eastwards through North China, for we have it from Chusan 

 Island and from the Philippines." He also notes that "The 

 seasonal (?) forms differ less than usual : T. rama [and also 

 %\ cingala'] is probably the best-marked wet type, T. santana, Felder, 

 intermediate, and T. venata (of which T. pallitana, Moore, is the 

 female) the dry ; but, on the other hand, it is possible that, as seems to 

 be the case in the closely allied T. betheseba, Janson, from Japan 

 and Hainan Island, no differing dry form may exist, and the slight
