seems to be there the usual form.”

Grose Smith. Wallace. Kirby. As far as I am aware, tliis 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 varuna , 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.

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 Minchirim 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 agusea, Rumpli., in flower, 
on which in July, 1893, the collectors obtained considerable numbers 
of both sexes by using a long bamboo-handled net. P. erebus , Wallace, 
P. sycorax, and P. hageni, Rogenliofer, 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. sycorax depositing eggs on a lime tree ( Citrus sp.) at Bandar Quala 
in Serdang.
