through faintly by transparency ; all the veins of the fore wing from base 

 and the veins of the hind wing on the outer third margined narrowly with 

 black, that towards the terminal margin broadens, coalesces, and forms a 

 band on the extreme margin ; on the fore wing this is comparatively broad 

 0,nd the black markings more or less triangular ; at each vein on the hind 

 wing the band is reduced to mere black lines, slightly broader anteriorly 

 than posteriorly. Underside: fore wing white, costa black, apex suffused 

 with yellow, all the veins from the base broadly bordered with black that 

 does not extend towards their apices ; an ill-defined transverse, some- 

 what diffuse ; postdiscal black band from veins 1 to 7. Hind wing : rich 

 chrome-yellow up to a postdiscal black band, beyond which the ground-colour 

 is white with a series of large, terminal, vermillion-red, rectangular or 

 truncated, cone-shaped spots ; veins from base bordered somewhat narrowly 

 but conspicuously with black. Antennae brownish black, head and thorax 

 clothed with long bluish-grey hairs, abdomen glaucous white ; beneath : 

 the palpi and thorax greyish white, abdomen white. Female very similar, 

 the black edgings to the veins on fore and hind wings on both upper and 

 undersides broader ; on the upperside the veins of the hind wing as well 

 as of the fore being black right up to the base. Ufperside : fore and hind 

 wings with a well marked, dusky-black, postdiscal, diffuse band ; cell of the 

 fore wing traversed by three slender, longitudinal, black lines. Underside : 

 the yellow and vermillion tints brighter than in the male. Expanse : 

 86-90mm. 



Larva. — Colour dull blue-green. Head and all the segments dotted 

 with minute blue tubercles, those on the head and sides black-tipped ; 

 dorsal surface pubescent ; a lateral fringe of soft white hairs below the 

 gpiracles. 



Pupa. — " Bright green. Sharply pointed at the head, with two strong 

 lateral points and keeled on dorsal surface of thoracic segments ; an 

 interrupted, yellow, dorsal line, and a short, curved, crimson line on each 

 side below thoracic segments bordering a small, white, irregular, black- 

 speckled spot." {E. E. Green, MS. note as quoted by Moore.) 



This description has been taken from Bingham's Butterflies, in the Fauna 

 of British India. In another pupa obtained in the Kanara District of the 

 Bombay Presidency there was no sign of the crimson-bordered, black- 

 epeckled spot. It was very like the pupse of the Appias (v. PI. 1, fig. 18a) 

 genus only larger and stouter. The butterfly is certainly not ever found 

 in the plain country but will be met with at Mahableshwar hill-station in 

 the Bombay Presidency and, may be, further north as far as Thana in the 

 hilly jungles. It is extremely like Delias eueliaris at first sight but has 

 much more pointed wings and is a far faster and stronger flier ; the red on 

 the underside of hindwing is of a pinker tint and the whole insect is more 

 laristocratic looking. It inhabits the big evergreen jungles of the Western
