mentions B. celinde, StoU, andD. cheops, Felder, while Mr. Distant 

 cites D. sondaica, Boisduval, as occurring in that island. The latter 

 species belongs to the group of D. tiiUia, Cramer, which is quite dis- 

 tinct from the group of D. celinde, Stoll. D. dis in the male is a 

 species abundantly distinct from any species of the latter group, a 

 list of which, as far as I have been able to make them out, is given 

 below :— 



1. Discophora celinde, from Java {^ioYi.) =.aristide8, from the 



Indies (Fabricius) =i{«w«om, from Timor (Doubleday and 



Hewitson). 

 la. D. celinde, var. continentalis, from India (Staudinger). 

 lb. D. celinde, var. andamensis, from the South Andaman 



Isles (Staudinger). 



2. D. menetho, from India (Fabricius). 



3. D. necho, from Java (Felder). 



4. D. cheops, from Borneo (Felder). 



5. D. dis, from Sumatra and Borneo (de JNiceville). 



6. D.ogina, from (Hiibner). Grodart describes the 



male of B, ogina from Java, but does not refer to the 

 species as being Hiibner' s. The latter figures a male, 

 while Semper figures a female from the Philippines 

 ■=meUnda {teste Semper), from Luzon (Felder). 



7. B. iamZ)Z«scB, from Halmaheira (Grilolo) {Feld.ei')= celebensis 



(teste Rothschild) from Celebes (Holland). 



Nos. 6 and 7 of the above list differ from the other five species in 

 having more than two ocelli to the hind wing on the underside. The 

 genus sadly requires to be monographed ; it is highly improbable 

 that all the species given above as distinct are really so. Both 

 Butler and Semper retain the B. menetho of Fabricius as distinct, 

 while Kirby and Distant place it as a synonym of B. celinde. If 

 Donovan's figure of it (female) is correct, I possess a specimen from 

 Java agreeing closely with the figure, and the species appears to be 

 distinct from B. celinde. 



B. dis is described from two pairs kindly sent me by Dr. L. 

 Martin, of Deli, Sumatra, and one male subsequently received from 

 Mons. A. de Plason, from Nanga Ba-dau, Borneo (1886). Dr. 

 Martin has bred the larva on Imperata arundinacea and Saccharum 

 officinale (sugar-cane). The larvae invariably keep in pairs.
