158 Journal of the F,M.S. Museums. [Vol. X, 



The Director of the Zoological Museum, Buitenzorg, 

 has been kind enough to send me for identification a small, 

 but interesting, collection of Danaines from Java and 

 neighbouring islands. Two new subspecies from the 

 islands of Krakalau and Verlaten arc described from this 

 nialerial. 



My thanks are also due to the Acting Curator of the 

 Sarawak Museum for the loan of Bomean specimens from 

 that Museum and to Mr. E. J. Godfrey for Siamese speci- 

 mens for comparison. The collections in the Raffles 

 Museum, Singapore, have also provided material for addi- 

 tional notes. 



The " Malaysian " buttertlies considered in these and 

 subsequent notes are confined to a " true Malaysian " sub- 

 region ^ which, for Museum i)urposes, I regard as those 

 countries lying between Lat. 10° N. and 10° S. and Long. 95"^ 

 and 120° E., i.e., tlie Malay Peninsula, Borneo, Sumatra and 

 Java and adjacent islands. An exception is made in the 

 case of a few bulterllies Ironi S.W. Siani (Tasan, Lat. 10° 

 30' N., and Hat Sanuk, Lat. 12^ N.), which are included 

 in the F.M.S. Museums collection. They are of interest 

 in that some species are insepai'able from Malayan forms, 

 while others obviously belong to the Siamese-Tenasserim 

 fauna. 



The following new forms and new combinations are 

 introduced in this paper : — 



8a. Danaida juventa Cv. krakaiaiiae subsp. nov. 

 23. Danaida plexippus I^. plexippus L. connectens f. nov. 

 24a. Danaida melanippus Cr. insularis subsp. nov. 

 27o. Euploea crameri Lac. snelleni subsp. nov. 

 34. Euploea core Cr. distanti Moore, comb. nov. 

 37a. Euploea alcathoe Godt. iiwnticola subsp. nov. 

 40. Euploea dufresne Godt. hurrisi Feld. comb. nov. 

 40. Euploea dufresne Godt. milhrenes Fruhst. comb. nov. 



40. Euploea dufresne Godt. coiwallaria Thicjue, comb, 

 nov. 



40. Euploea dufresne Godt. nica Fruhst. comb. nov. 



40. Euploea dufresne Godt. tyrianlhina Moore, comb. nov. 



40. Euploea dufresne Godt. lacordairei Moore, comb. nov. 



40. Euploea dufresne Godt. baweanica Fruhst., comb. nov. 



^\ true Malaysian subregion, as opposed to a wider area in 

 which a non-Malaysian element is evident although not necessarily 

 predominant, e.g. an area including Celebes, Palawan and Slam, 

 to ail of which countries many " true " Malaysian species extend. 



The boundaries for this true Malaysian subregion must neces- 

 sarily be arbitrary to some extent. For Museum purposes I have 

 extended the northern boundary to Lai. 10° N., although, as Mr. 

 Boden Kloss points out, the fauna of the Malay Peninsula between 

 7° and 10° N. is as much Indo-Chinese in character as Malayan. 



BoDEX Kloss, 1918, p. 245, writes : " Malaysian — Pertaining 

 to the Malay Peninsula, Sumatra, Borneo and Java. Malayan — 

 Pertaining to the Malay Peninsula, Cf. Sumatran, etc" See also
