NEW OEIENTAL PAPILIONID^E. 



By the Hon. L. W. Rothschild, Ph.D., F.E.S. 



1. Troides goliath atlas, subsp. nov. 

 $ . The cell-patch of the fore wing separated into spots ; there 

 are three white spots in front of the second median vein on the under 

 side of the fore wing, the females of the other forms of goliath having 

 less than three spots between the two median veins. The disc of the 

 hind wing is greyish white above, and densely dusted with black, 

 l)eing on the under side white proximally and yellow distally. 



Hab. Kapaur, Dutch South-west New Guinea. Two females 

 collected by W. Doherty in January and February, 1897. 



2. Troides priamus arriianus, Feld. (1859). 



I have now a better series of Arru specimens of T. priamus 

 than in 1895, when I published the Revision of Eastern Papilios, 

 and am inclined to treat them as representing a separate sub- 

 species, although only the majority of the individuals differ from 

 New Guinean ones. Among my specimens there is a very 

 remarkable variety of the male, which I think should be recorded 

 under a name of its own : — 



S' ab. chrysophila, nov. — Hind wing, on upper side, without black 

 spots, but instead with four brown submarginal ones, of which the 

 upper three are centred with gold ; behind the costa a large golden 

 spot. On under side these spots enlarged, also the fourth submarginal 

 one being centred with gold ; the fore wing much more extended 

 green than in ordinary specimens, the black distal band being only 

 represented by a spot situated in the subcostal fork. Length of fore 

 wing only 70 mm. 



3. Troides hrookinna natunensis, subsp nov. 



? . Intermediate between albescens from the Malay Peninsula 

 and brookiana from Borneo. Nearest to the latter, but the white 

 markings larger. 



Hab. Burguran, Natuna Islands.
