Sub-genus Macrdplwa. 



26. Euphea (Macroplcea) corns, Fab. 



Papilio corns, Fab. Ent. Syst. iii, p. 41, (1793). 



Sub-sp. E. corns butleri, Moore, (Syn. E. Godmani 

 Moore). 



This >ub-species is confined to Borneo ; the typical 

 form occurs in Ceylon and other sub-species range from 

 Burma through the Malay Peninsula and Sunda Islands 

 to Palawan and Celebes. 



Sub-genus Danisepa. 



27. Euplcea (Danisepa) diocletiauus, Fab. 



Papilio diocletianus. Fabricius. Ent. Syst. III. 1, p. 40, n« 



118 (1703). 

 Papilio Radamanthus. Fabricus, Ent. Syst. III. l,p. 42. n. 



127 (1793). 

 Sub-sp. E. diocletianus lowei, Butler. 



The typical form according to de Niceville occurs in 

 India, Burmah, Indo-Cbina, Malay Peninsula, Sumatra, 

 Billiton, Banka, Natuna Is. The sub-sp. lowei is con- 

 fined to Borneo. E. schreiberi, Butler, has been wrongly 

 recorded from Borneo, it is apparently confined to the 

 island of Nias. 



[As I pointed out elsewhere * the females of E. dio- 

 cletianus lowei are extremely rare whilst the males are 

 common ; in Singapore both males and females of E. 

 (Dan.) diocletianus, PVo., are common. It is at least 

 curious that the female lowei should differ noticeably 

 from female E. diocletianus whilst the males of loth 

 e form are almost identical. 



The species is mimicked by: — Males: — Euripus hali- 

 tJierses Q forma pfeifferce, Papilio caunus mendax $ , 



Females : — Euripus lialitherses 9 forma euplcroidcs, 

 Papilio caunus mendax 9 Mimeurplcea and also hadamau- 

 thus]. 



From Borneo ; it occurs in Nias.
