yellowish orange, the dark streak at the end of the cell is indistinct, (hi the 

 posterior wings, the surface is sericeous, and the broad dark marginal band which 

 covers the outer third has a glossy purplish tinge; the costal margin is naiTOwly 

 yellow. 



Kxjjause of wings : 2^ inches. 



Hab. Korrido. 



One specimen only. Nearest to D. znmboanga Felder. 



28. Appias saina sp. nov. 



Male. — Upperskie resembles A. mariae Semper, but the white spot between the 

 two upper median nervules of that species is absent, and the two spots towards the 

 apex of A. Saina are less distinct, the black apical area of the anterior wings and 

 the black margin of the posterior wings is somewhat narrower. 



On the ttnderside of the anterior wings the ajjex is glossed witli liglit purplish 

 brown, with the two white spots very indistinct ; the basal area is tinged with yellow. 

 In A. mariae the three white spots are much more distinct, and the basal area is 

 white. On the posterior wings the whole of the surface, except the dark marginal 

 border, is yellow ; in the dark border, above the U])pprmost median nervule, is an 

 indistinct yello\vish white spot. 



Female. — Upperside resembles the m,ale, but the white area is more tinged with 

 yellow. On the anterior wings the black a])ical area is centred with six white spots, of 

 which the two uppermost are somewhat elongate and conHuent. the third is distinct 

 and oval; the three lowest, which are parallel with the outer margin, are smaller, the 

 lowest being nearly obsolete. On the posterior wings the dark marginal band is broader 

 than in the inale and more diffused inwardly. 



Underside: anterior wings with the five upper subapical white spots confluent, 

 and densely dusted with yellowish scales ; the sixth spot is distinct and scarcely 

 separated from the white area by a few dark scales ; the white area is tinged with 

 yellow, more brightly so towards the base; posterior wings bright yellow with a 

 broad sinuate dark band crossing the outer third from the costa at the apex to near 

 the abdominal margin; the outer two-thirds of this band is densely irrorated with 

 yellow scales, which form irregular and ill-defined somewhat conical confluent spots 

 between the veins, having their bases on the margins. 



Expanse of wings: 2^ inches. 



ILdi. : male, Humljoldt Bay ; female, Biak. 



Two males from the former place and a fertude from the latter. It is possible 

 that the latter is not rightly "married" to the former, and that each sex may be 

 entitled to a different consort ; but the general configuration of the black marginal 

 area of both sexes is similar, and in the absence of the opposite sexes from the 

 same localities I am induced to place them together. The female is nuich less broadly 

 margined with black than the same sex of A. mariae, and is not unlike \]\q fem(de 

 of A. ega Boisd. on its upper surface. 



29. Belenois pallida sp. nov. 



M.\LE. — Upjierndt: both wings lacteous wlille with broad black marginal bands. 

 Anterior wings with the base and costal margin to half its length densely dusted 

 with grey scales, thence to the apex and along the outer margin broadly black ; the 

 inner edge of the black area, which is very irregular, e.xtending across the apex, at
