202 L. de Niceville — List of the Butterflies of Ceylon. [No. 3, 



seasonally dimorphic; specimens taken at a considerable elevation in 

 the dry cold weather (such as Nuwara Eliya in January) have the 

 underside somewhat deep fuscous. It has a wide rano^e in. India, 

 Indo-China, China, and Malayana, extending even to the islands of the 

 Pacific. It has frequently been bred. 



101. Catochrysops strabo, Fabricius. 



A common species everywhere in Ceylon- It is fonnd from India 

 to Australia. It has frequently been bred ; the larva feeds on Ougeinia^ 

 Schleichera and Dolichos. 



102. Catochrysops lithargyria, IVIoore. 



Not common in Ceylon, from whence it was originally described, 

 but occurs both in tlie low (Colombo) and hiil (Nuwara Eliya) country. 

 It is very closely allied to C. strabo, Fabricius, the females been in- 

 distinguisbable. The males, however, are readily differentiated, the 

 male of G. strabo being lilac, of G. lithargyria a pale silvery blue. It has 

 been recorded from m.any localities between India and Australia where 

 G. strabo is found, but never without that species. Its transformations 

 are unknown. 



103. Catochrysops cnejus, Fabricius. 



Very common everywhere in Ceylon, particularly so in the Northern 

 Province. Its range is immense, being found from India througli 

 China, Malaya and Australasia to the South Sea Islands. It has fre- 

 quently been bred on various plants of the Natural Order Leguminosse. 



104. Catochrysops pandava, Horsfield. 



Local and not common, found towards the north of the island and 

 along the North Central Road, also at Hambantota. It is not nearly 

 as widely spread as the other species of the genus given above, but 

 occurs all over India and in many of the Malayan islands as far east 

 as Bali and Sumba at all events. It is highly seasonally dimorphic, and 

 the larva feeds on the young fronds of Cycads. 



105. Tarucus theophrastus, Fabricius. 



Prefers the hottest and di-iest parts of the Island, such as Hamban- 

 tota in tlie south and the Jaffna district in the north, flying in July. 

 It is found in Northern Africa, Sacotra, Arabia, in many parts of India, 

 and in the Malayan island of Suraba. Dr. Holland has described a 

 Tarucus clathratus from Celebes, which probably is the same species. The 

 transformations of T. theophrastus are well known, the larva feeding in 

 Zizy pints.
