734 GODMAN AND SALVIN ON NEW BUTTERFLIES. [June 1 8, 



the end of the cell and six submarginal spots running from the costa 

 to the anal angle, those nearest the latter nearly white ; the central 

 portion and inner margin of secondaries dull yellowish white, the 

 base and outer margin broadly black, the latter including six obso- 

 lete yellowish spots. 



Beneath like the male, except that the primaries have no yellowish 

 spot spreading from the inner margin over the median branches. 



Hab. New Ireland. 



Obs. Belongs to the Delias group. The male resembles on the 

 upperside the same sex of P. aruna, Boisd., as figured by Hewitson, 

 and D. inferna, Butl. The female on the upperside, and both 

 sexes on the under, more nearly resemble P. descombresi, Boisd. 



PlERIS ETJRYGANIA. 



3 . Exp. 3 - 2. Above white, the apex of the primaries chrome- 

 yellow, margined with the black costa and outer margin and a curved 

 band running from inside the cell to near the anal angle, the outer 

 margin of the secondaries broadly black. 



Beneath, primaries chiefly black, yellow apical spot as on the 

 upperside, the proximal end of the cell yellow, and the inner margin 

 white ; the secondaries at the basal half yellow, black towards the 

 distal half, across the black a distinct band of crimson, which becomes 

 orange where it meets the yellow near the inner margin. 



2 . Like the c? , except that the basal portion of the primaries is 

 black, the outer margin of the secondaries is more broadly black, 

 and the inner portion of the secondaries, together with inner margin 

 of the primaries, pale yellow. 



Beneath same as the male. 



Hab. New Ireland. 



Obs. This is a very distinct species, apparently belonging to the 

 Delias group. 



PlERIS LYTjEA. 



$ . Exp. 2-5. Above black, a large subtriangular spot on the 

 inner margin, extending to just within the cell, three apical spots of 

 the primaries and the basal half of the secondaries white. 



Beneath, black arranged as above, a submarginal row of large 

 white spots on both wings ; the base of the primaries and the greater 

 portion of the base of the secondaries sulphur-yellow ; the rest of the 

 secondaries (not occupied with black) is white. 



Hab. New Britain. 



A female, apparently belonging to the Belenois group ; we have 

 no nearly allied species with which to compare it. 



Papilio segonax. 



cJ. Exp. 4 - 6. Primaries slightly falcate, secondaries produced, 

 Upper surface rich metallic green, a median row of five nearly cir- 

 cular spots starting from the apex to the space between the third 

 and fourth median nervules, a similarly coloured subtriangular spot 

 near the middle of the inner margin, and a very small one close
