 3. Papilio bridgei togonis snbsp. nov. 



(J. Pnjrilin hmlgei trynni, Rothschild (iMn Mathew, 1889), Nov. Zool. ii. p. 310 (1895) (partim ; 

 Isabel). 



S- Similar to P. bridgei frijoni. Forewing, above, with a row of seven spots, 



geuerally with some additional white scaling behind SM'', the first spot being 



small, occasionally absent, rarely preceded by a minute eighth spot. Band of 



hindwing outside the cell, patches SC!^— M' decreasing in length, the upper three 

 patches distally excised, the others more or less rounded distally, especially patch 

 R-— R', the nervures more or less extended black between the patches ; white 

 marginal spots more prominent than in the only known c? specimen of tri/oni. 



On the underside there is sometimes a white spot on the forewin" between 



M= and SMI 



?. Forewing as in tri/oni, but the marginal spots rather smaller above and 

 larger below. The white central area of the hindwing less pure white than in 

 tryoni, the upper three patches outside the cell rather shorter ; the submarginal 

 spots, which are bright orange in tri/oni above and below, white, more or less shaded 

 with orange, especially proximally, the seventh sjiot of this row on the up2)erside 

 the smallest of all, while in tryoni it is the largest both above and below. 



Hab. Isabel, Solomon Is., June— July 1901 (A. S. Meek & Eiclihorn). 



A series. 



4. Papilio bridgei ortegae subsp. nov. 



c?. Wings, upperside : baud of forewing intermediate between those ot bridt/ei 

 hecataeus and hridgei tognnis, consisting of eight spots and an additional spot behind 

 SM2, spots R2— M' smaller than spot M'— M^ and more proximal than spot R^— R-, 

 being rather larger than in hecataeus, spot SC^— SO* about half the size of spot 

 R- — R'l Band of hindwing as in hecataeus. 



U/tdrr.^idi' : forewing with three small white subajncal spots SG^— R' ; sub- 

 marginal spots of hindwing smaller and less shaded with orange than in hecataeus. 



?. Wings, Ujjperside: forewing with larger cell-patch than in hecataeus, white 



discal spot SC!^— SC^ less pure in colour, patch R-— R' larger. On the underside 



these spots are also larger, and the marginal spots R'— M" are nailhead-shaped, 

 being more or less completely merged together with an admargiual spot each. 



llab. Florida Island, Solomon Is., January 1901 (A. S. Meek & Eichhorn). 



Two pairs. 



This form connects hecataeus with togonis, and the latter leads over to bridgei, 

 while extreme individuals of hecataeus come near /jrospero. These insects, inclusive 

 of togonis, are geographical varieties of one species (of which the oldest name is 

 hridgei). 



5. Delias schoenbergi choiseuli snbsp. nov. 



(?. Differs from the two other subspecies of schoenbergi especially on the 

 underside, coming nearest to sch. isahellae. The black area of the forewing below 

 as much restricted as in isabellae, but less shaded with white at M-; the basi-discal 

 area more extended yellow. On the hindwing the red submarginal patches are
