Male. Wings above wbite, with a faint pale Rreenish tin^o ; anterior wings with the base and l)asal 

 half of costal area bluish-grey (this is much more prononnced in some specimens than in others), 

 remainder of costal margin narrowly black, apex ami outer margin (the last inwardly dentatcly sinuate), 

 and a submarginal curved fascia commencing at fifth subcostal ncrvulc, forming a largo subquadrate spot 

 between the first and second median nervules, and from thence sometimes carried obscurely and narrowly 

 towards outer angle, black ; posterior wings with the base more or less bluish-grey, and with a marginal 

 row of blackish spots placed between the nervules. Anterior wings beneath white, with a faint pale 

 greenish tinge, basal area sulphureous, apical area pale ochraceous, and with the black sul;marginal fascia 

 above more or less plainly visible beneath ; posterior wings pale ochraceous. Body above with the 

 pronotum dark bluish-grey, the abdomen pale fuscous ; body beneath and legs more or less concolorous 

 with wings. 



Female. Wings above white, with a faint pale greenish tingo : anterior wings with the basal area 

 dark greyish, the apex and outer mai'gin broadly lilaek, and containing four subapical white spots — tlie black 

 area obliquely ci'osses the upper extremity of cell, is more or less truncate to second median nervule, and 

 narrowed between second and third median nervules ; posterior wings with the base dark greyish and the 

 outer margin broadly blackish. Anterior wings beneath as above, but with the basal area ochraceous, 

 and the apical black area from the four whitish spots to apex bluish-grey, with the extreme margin 

 ochraceous ; posterior wings with the extreme margins and neuration ochraceous, the black margin above 

 being seen as bluish-grey beneath. 



Var. ((. 2 . The posterior wings beneath pale ochraceous, the outer margin more or less violaceous. 

 (Tab. XXV., fig G.) 



Var. h. 2 . The posterior wings beneath dark ochraceous, with a broad chocolate-brown outer 

 margin containing a few obscure ochraceous spots. (Tab. XXV., fig. 10.) 



Var. c. 2 . Wings beneath with the apex of the anterior wings and the whole of the posterior wings 

 dark ochraceous, the last with only faint indications of the dark chocolate-brown outer margin.

Hab.— Malay Peninsula ; Province Wellesley (coll. Dist.) ; Perak fBiggs— coll. Dist.) ; Malacca, 

 Ayer-panas (Godfery— coll. Dist.).— Sumatra (Brit. Mus.).— .Java (Brit. Mus.).— Borneo (Brit. Mus.); 

 Saudakan (Pryer — -coll. Dist.). 



Both sexes of this species are of a very variable character. Thus the males vary in the 

 intensity of the black markings above, a peculiarity which is strongly exhibited in a series of 

 North Bornean examples now before me, in the palest specimens of which the black marginal 

 spots to the anterior wings are almost obliterated, and the black markings of the anterior 

 wings are pale and somewhat effaced. 



Some confusion has existed in the identification of this species, several authors having 

 considered the Catophcuja leis,I{.u]m., as being synonymic with the Prt^tVto ;;aM///(fl, Cram., but 

 besides colour differences in the female sex— such as the width of the dark margin to the 

 posterior wings — the males are very distinct.
