Hagen, and notes that " This aberration is not confined to Sumatra, but 

 seems to be there the usual form." 



576. *Papilio (Pangerana) pkiapus, Boisduval. 



Grose Smith. Wallace. Kirby. As far as I am aware, this species 

 is confined to Java and Borneo (Rothschild, however, says that it " Does 

 certainly not occur in Borneo"), but it is possible that it may be found in 

 the extreme south-east of Sumatra adjoining Java. Dr. Wallace places 

 it in the memnon group, but as the males differ greatly in shape from 

 all the species of that group, and moreover have the abdominal mar- 

 gin of the hindwing folded over anteriorly twice as in the species of 

 the nox group, P. priapus appears to me to be better placed in the 

 subgenus Pangerana, Moore, of which Papilio varima, White, is the type, 

 and which will probably embrace P. nox, Swainson, and its allies. All 

 the species of this group, as well as all Troides, have as imagines a very 

 strong scent, and are certainly highly protected.

P. (Pangerana) sycoraz, de Niceville, Journ. Bomb. Nat. Hist. Soo., vol. viii, 

 p. 54, n. 15, pi. M, fig. 1, male (1893). 



Grose Smith. Distant. Hagen. Originally described from Sumatra, 

 but found also in the Malay Peninsula. In Sumatra it flies from 

 Bindjei to south of Bekantschan, but not on the Central Plateau. 

 We have numerous specimens from Selesseh, and Dr. Martin took 

 it himself at Quala Miuchirini near Bindjei, and at Roemah Kenang- 

 kong near Toentoengan, throughout the year. Dr. Hagen has quite 

 recently caught it in Kedjang in Southern Sumatra. It has a bold and 

 high flight like a Troides, and is not easily captured, but in the forest 

 near Selesseh there was a tree of Jambosa aqusea, Rumph., in flower, 

 on which in July, 1893, the collectors obtained considerable numbers 

 of both sexes by using a long bamboo-handled net. P. erebics, Wallace, 

 P. syeorax, and P. hageni, Rogenhofer, are all apparently commoner in 

 the female than in the male sex, which is the reverse of nearly all 

 other species of Papilio. Herr Puttfarcken has observed a female of 

 P. sycoraz depositing eggs on a lime tree (Citrus sp.) at Bandar Quala 

 in Serdang.
