or somewhat larger, the maririii.-il sjiots being at least twice as large as in other 

 forms of aegeus. Below, there are in some sjieciraens, besides the diseal series of 

 blue lunnles, two reddish orange diseal spots present, covered by the two last bine 

 markings ; the additional orange mark which stands between veins 2 and 3 is 

 joined b_v a broad bar to tlie respective submarginal spot. 



b. 9-f. blanca f. nov. — Forewing as in ^Vallace's fig. 4 of t. 3, I.e., but the 

 marginal spots more prominent. Hiudwing as in the palest specimens of or/iu-ti'i.'i, 

 but the black diseal patches between the median branches midway between outer 

 margin and cell, lieuce distinctly nearer the cell than in ormfniis $ -f nmnm/a; the 

 two anterior orange submarginal spots within the anterior black area are as large 

 as in Wallace's fig. 4, I.e. ; the marginal spots as large as in the preceding ? -form . 

 Below, the first submarginal spot is joined along vein 7 to the marginal spot. 



IJa/i. Kei Toeal (Little Kei Island), collected Ijy Capt. H. Cayley AVebster in 

 January to March 1896. 



Easily distinguished from the allied forms in the male by the band of the 

 hindwing not being extended be3'ond vein 2, and in the female by the larger 

 marginal spots to both wings. 



The specimens from Goram, figured by Wallace, I.e., seem to belong to tliis 

 subspecies, not to aegeu.^ ormenus Gner. 



•J. Papilio castor formosanus subsp. nov. 



cJ. Ujjpersule : black. Hindwing produced into a short tooth (2i mm. in 

 length) at the first median branch, with a diseal series of fonr spots between costal 

 margin and vein 4 : the first rounded, diameter .2f mm. ; the second rounded basally, 

 truncate exteriorly, length G mm., breadth 4i ; the third 1 mm. short of cell, 

 obli(|uely truncate exteriorly, having a length of 8 mm. at vein fj"and of 6i at vein •") : 

 the fourth elongate-ovate, .j mm. long and barely 2 mm. broad. 



Underside : forewing with a minute white dot upon the second discocellular 

 vein, and with extremely small white marginal spots between the veins. Hind- 

 wing with the first diseal spot represented only by a few white scales: the other 

 three spots stand farther away from the cell than above and are shorter, their 

 respective length being 4, 0, and 4 mm. ; between veins 2 and 4 there are two more 

 diseal white spots of very small size (1 to 1^ mm.) ; the white marginal Innnles 

 small. 



?. Uppetside : brownish black. Forewing with a minute white dot on the 

 second discocellular vein ; marginal white spots larger than in male, those between 

 the median branches measuring § mm. to 1 mm. in width. Hindwing with three 

 diseal creamy buff patches between veins 4 and 7, similar to those of the tnale, and 

 a minute spot before and another behind them ; two indistinct submarginal spots 

 between veins and 8. 



Underside : forewing with a distinct milky-white spot on the second disco- 

 cellular vein, 11 mm. long; the marginal sjiots as above; a series of indistinct, minute 

 white, submarginal dots, situated between veins lb and 7 upon the internervnlar 

 folds about 5 mm. from tlie margin. Hindwing with a series of seven diseal sjiots, 

 the four first sinuate exteriorly, larger than the three others, the third the largest;
