BUTTERFLIES OF BORNEO 95 



Genus Precis. 



118. Precis iphita, Cr. 



Papilio iphita, Cramer, Pap. Exot. lilt. 209. C. D. 

 (1782). 



Precis neglecta, Swinhoe, A. M. N. H. (7) vol. 3. p. 103 

 (1899). 



Sub-sp. P. iphitat osca, Fruhst. 



This sub-species is restricted to Sumatra and Borneo 

 other forms are found in China, India, Burma, Java, 

 lesser Sunda Is. Malay Peninsula, Palawan. 



The splitting up of this and other species of the 

 genus into sub-species cannot be regarded as altogether 

 satisfactory. The wonderful results obtained by G. 

 A. K. Marshall (of Trans. Ent. Soc, Lond. ) 



from his breeding experiments with African species of 

 Precis afford convincing proof of the extraordinary 

 plasticity of the species of this genus and until similar 

 experiments are conducted with the Indo-Malayan 

 species we can have no worthy evidence of the con- 

 stancy of the sub-specific or geographical forms distin- 

 guished by Fruhstorfer (Berl. Ent. Zeitsch. XLV p. 22. 

 1900). 



Precis neglecta Swinhoe appear to be nothing but 

 an aberration or seasonal phase of P. iphita and in our 

 present state of ignorance I have no hesitation in sinking 

 the name as a synonym. 



119. Precis hedonia, L. 



Papilio hedonia, Linnaeus, Mus. Olr. p. 279 (1764). 



Sub-sp. P. hedonia ida Cr. 



This form occurs in the Malay Peninsula, Great and 

 Lesser Sunda Is. Philippines, Palawan, Sumba, Flores. 

 Other forms occur in Celebes, Moluccas, New Guinea 

 and Australia.
