New Butterflies and a Moth from Biak. 181 



and outside end of cell is washed with orange. A black marginal 

 band as above but twice as wide and bearing 3 large somewhat 

 heart-shaped spots of bright orange, their apices resting on the 

 margin. Three small marginal spots of same colour in 4^6. 



$. Upperside white. Forewing blackish at base. Costa, apex, 

 and outer margin black with a well-defined inner edge. A marginal 

 row of white spots decreasing in size from cellule 6-2, those in 4r-2 

 being close to margin ; a dot before the first spot near costa. Hind- 

 wing with basal part including cell, pale yellow. A black marginal 

 border 3 mm. wide, from apex to first submedian, its inner edge 

 crenulate. Three yellowish marginal dots in cellules 2-4. 



Underside similar to (J. Forewing with increased apical and costal 

 black, and yellow apical spots smaller than in (J. Basal yellow fills 

 half the cell. Hindwing with distal area from centre of cellule 7 to 

 inner margin, bright orange, basal half yellow. Marginal band 4 mm. 

 wide bearing spots of bright orange as in cJ, the spots in 4-6 well 

 developed, the last being outside the band. 



Length of forewing : (J 29"5 mm., $ 26*5 mm. 



A series. 



7. Delias bosnikiana, sp. nov. 

 (Plate XXIV, fig. 1.) 



This species bears a superficial resemblance to the 

 preceding one, but we think it belongs to the poecilia 

 group. 



o . The forewing is more produced at the apex than in mvUicohr. 

 It differs above in the much narrower black margin which only 

 reaches just below vein 4, and in the consequent absence of apical 

 spots. The hindwing bears some black scaling around the ends 

 of veins 2, 3, and 4. The underside differs from multicolor in the 

 increased costal and apical black, and the larger apical spots all of 

 which are white. The inner-marginal orange area is more strongly 

 defined and extended basally. The marginal black is broader and 

 the spots smaller, those in 5 and 6 being absent. 



$. Upperside black, basal half sparsely powdered with white. 

 Forewing with three large white apical spots prolonged basad, a faint 

 white subcostal streak, a rounded spot in 3, a small spot in 2, and 

 a dot in Ic. Hindwing with costa white. A submarginal row of 

 pinkish-white spots in 2-6, somewhat heart-shaped, their apices 

 directed to the margin. 



Underside of forewing with basal half white, tinged with lemon - 

 yellow in cell and outside its lower edge. Costa black to base.
