1. Delias ladas 



sp. IIOV. 



;Male. — Uppcmide : both wings wliitc Anterior wings with thi' costal margin 

 very narrowly black to two-thirds from the base, the apical third black, the black 

 area extending obliquely from the costal margin, a little beyond the end of the 

 cell, to the outer angle, its inner edge being dusted with white scales. Posterior 

 wings white, with the outer mai'gin from a little below the first subcostal nervule 

 to the anal angle narrowly black, rather more widely black in the middle, the inner 

 edge of the black area dusted with white scales. 



Underside : anterior wings with the costal margin more broadly black than on 

 the upperside to the end of the cell ; thence the black area covers the apical area 

 obliquely to the outer angle; a little befur(> the apex are three yellow spots placed 

 obliquely between the veins, the middle spot the smallest, the lowest spot the 

 largest ; the cell and the rest of the discal area white. Posterior wings black, with 

 the basal space above the costal ner\nre yellow; a narrow yellow streak on the 

 margin above the first subcostal nervule at the aixx, and an oblong yellow spot 

 below it, a little before the margin. 



Female resembles the male, but on the upperside the black area on both wings 

 is more extended, and on the underside tlie yellow spots are rather larger. 



Expanse of wings : 2| inches. 



This butterfly belongs to the group of D. ahnormis Wallace and A orn)/lioyi, 

 Godm. & Salv. There were nine specimens in the collection. 



2. Delias geraldina sp. nov. 



Female. — Upperside: both wings white. Anterior wings with the costal 

 margin from the base to a little beyond half its length grey, thence to the apex 

 greyish black, the black area covering the apical third of the wings ; its inner edge 

 to the upper median nervule oblique, thence becoming nearly vertical to the outer 

 angle. Posterior wings rather broadly black on the outer margins from a little above 

 the apex, where it is broadest, to the anal angle, towards which the dark liand 

 becomes interrupted on the veins and is dusted with white scales. 



Underside: anterior wings with the costal margin above the cell and the cell at 

 its base grey, irrorated with yellow scales; the apical third as on the upperside, but 

 rather paler and more sericeous, and its inner edge extending obliipiel}' from the 

 costa, at two-thirds its length from the base, to the outer angle; in this space is 

 situate between the veins a row of five yellow spots, the first and second spots con- 

 tiguous, dividcMl by tlic (hinl sulico-lal iirrvnle, the 1 hrei- other sjjots lieing distinct
