sometimes joins apical black, and the 4tli (at end of 1st 

 median nervule) is ahvays minute. Hindwing : base 

 slightly fuscous ; a faint orange suffusion, fading out- 

 wardly into yellow in basal region ; 6 hind-marginal spots 

 of small size, of which the 1st (at end of 2nd sub-costal 

 nervule) is minute, and the 2nd and 6th smaller than tlic 

 3 others. Underside. — Forewing : no basal fuscous, 

 and only some faint fuscous scales along edge of costa ; 

 orange-red suffusion brighter and spreading nearer to 

 extremity of discoidal cell ; in place of a])ical fuscous 

 3 small marginal nervular spots, of which the first is a 

 little before apex at end of 2nd subcostal nervule. Ilind- 

 loing : icltite, very faintly tinged Avith yellowish near base 

 and inner margin ; costa at and for a little distance fi'om 

 base bordered with orange-red; hind-marginal spots (espe- 

 cially the 1st) larger and rounder than on upperside. 



$. More or less universally suffused tvith pale creaviy- 

 ochreous, into which the basal orange-red (which is much 

 duller than in $ ) gradually fades ; on the discs the 

 nervures are all more or less clouded with whitish ; hind- 

 marginal spots much larger than in $ . Foreioing: apical 

 fuscous crossed by 2 or 3 ochreous internervular rays ; 

 a minute spot at extremity of sub-median nervure. 

 Underside. — In the paler specimens almost as Avhite as 

 in ^, but in the darker ones more or less tinted with 

 creamy-yellow generally. Foreioing : orange-red suffu- 

 sion fills discoidal cell, and faintly extends inner mar- 

 ginally almost to posterior angle ; hind-marginal spots not 

 enlarged as on upperside, but blacker and rounded. 



This beautiful Pieris is a very near relation of the 

 West African P, Rhodope, Fab. {=■ Poppea, Cram.), 

 and of the ]\Ialagasy P. Phileris, Boisd. ; it is, perhaps, 

 not quite so closely allied to P. Agathina, Cram. As far 

 as the ^s are concerned, the very conspicuous orange-red 

 basal suffusion of the forewings on the upperside readily 

 distinguishes P. Hcemus from all the three species named; 

 Rhodope and Phileris having only a very faint and much 

 smaller orange-yellow tinge, while in Agathina there is 

 none at all. Tiie fainter basal suffusion in the hindwings 

 is also wanting in all the three allied forms. On the 

 underside, Hccuius has none of the rich ochre-yellow of 

 Agathina, but its white is less pure than that oi Rhodope 

 and Phileris ; the hind-marginal spots, however, are 

 smaller than in the two latter, and agree very closely 

 with those of Agathina ; and the basi-costal orange-red
