SOME NEW LEPIDOPTERA FROM THE EAST. 



By the HON. WALTER ROTHSCHILD. 



PAPILIONIDAE. 



1. Troides priamus caelestis snbsp. nov. 



(S. In colour like '/'. jj//a»ius i/rril/eani/.s ; smaller ; the costal streak of fore- 

 wing narrower iu cell, the posterior streak extending down to base of wing, not 

 interrnpted in middle, thongh here the bine scaling is less dense : margin of hindwing 

 mnch more scalloped than in vrrillfantis, the marginal black liorder wider. On 

 nnderside the edge of the yellowish green onter area of the hindwing deeply sinuate 

 between veins 5 and T, less deeply also between veins 7 and 8, the yellowish streak 

 before vein 8 reaching down to praecostal vein, broad, not separated from the 

 yellowish area between veins 7 and 8, basal third of the costal vein covered with 

 yellowish green scales ; edge of cell very thinly lilack only between origin of 

 nervnles t and 7, while in urvilleatius this black border extends to origin of vein 2. 

 Hindwing with or without a golden yellow spot between veins 7 and 8 above and 

 lielow : one specimen has three small golden yellow snbmarginal spots between 

 veins 4 and 7. 



? . Wings deeper in colour above and below than in Hrvilleanus, and mnch more 

 constant in markings. Forewing with a large grey patch in cell, widest in front 

 (18 to 22 mm.), its basal edge very oblique, outer edge sintiate in middle, sinus 

 very variable in width and depth. Three discal patches between snbmedian fold and 

 vein 4 ; the lower one the smallest, mostly concave outwardly, sometimes reduced 

 to a short linear spot ; the second the largest, varying little in the twenty odd 

 specimens before me, always evenly concave distally, convex or pointed proximally, 

 about 12 mm. long ; the upper patch also elongate, less regular in shape, not 

 concave distally, varying in length from to 15 mm. Upon these three patches 

 follows, between veins 4 and !», a series of iive markings, of which the two ])osterior 

 ones are the smallest and sometimes obsolete ; the three upper ones generally 

 elongate and triangular, concave distally ; the two markings between veins 5 and 7 

 are mostly joined to the two upper spots of a snbmarginal series : this latter row of 

 spots is always complete, though the middle spots are often much reduced in size. 

 Tear-shaped patches of hindwing, both above and below, more deeply sinuate distally 

 between veins 4 and 6. 



On underside the discal patches of the hindwing are cream-colour, shading into 

 light chrome-yellow distally ; the black sjiot between veins 7 and 8 more basal than 

 in wrilleayivs, its basal edge being only 4 mm. distant from the point of origin of 

 the seventh nervule. 



Mesonotum with olive-bufl' median stripe. Basal segments of abdomen more 

 blackish than in vrrilleanus. 



Ilah. St. Aignan, Louisiade Archipelago, August to November 1S!(7 (A. S. 

 Meek); t3'pe : S. A series of both sexes. 



2. Papilio polydoms aignanus subsj). nov. 



S ? . Comes very close to the form from the Key Islands (t/iesmlia Swinh.), 

 and has likr this a red head : but (lifters in the red liairs of the front of the head
