riERIN/E. 35 



fading outwardly into yellow, in basal region; six hind-marginal spots 

 of small size, of which the first (at end of second subcostal nervule) 

 is minute, and the second and sixth smaller than the three others. 

 Under side. — Fore-wing : 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 apical fuscous three 

 small marginal nervular spots, of which the first is a little hc/orc apex 

 at end of second subcostal nervule. Hind-wing : white, very faintly 

 tinged with yellowish near base and inner margin ; costa at and for a 

 little distance from base bordered with orange-red ; hind-marginal spots 

 (especially the first) larger and rounder than on upper side. 



$ More or less universally suffused with j;a/e crcamy-ochrcous, 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 $, Fore-iving : 

 apical fuscous crossed by two or three ochreous inter-nervular rays ; a 

 minute spot at extremity of submedian nervure. Ukder side. — In 

 the paler specimens almost as white as in $, but in the darker ones 

 more or less tinted with creamy-yellow generally. Fore-wing : orange- 

 red suffusion fills discoidal cell, and faintly extends inner-marginally 

 almost to posterior angle ; hind-marginal spots not enlarged as on 

 upper side, but blacker and rounded. 



This beautiful Pieris is a very near relation of the West African 

 Poppea, Cram.,^ and of the Malagasy Phileris, Boisd. ; it is, perhaps, 

 not quite so closely allied to Agathina, Cram. As far as the $ s are 

 concerned, the very consjncuous orange-red lascd suffusion of the fore- 

 wings on the U}yper side readily distinguishes EuppcUii from all the three 

 species named ; Mhodope and Phileris having only a very faint and 

 much smaller orange-yellow tinge, while in Agathina there is none at 

 all. The fainter basal suffusion in the hind-wings is also wanting in 

 all the three allied forms. On the under side, Eilppellii has none of 

 the rich ochre-yellow of Agathina, but its white is less pure than that 

 of Poppea 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 of the hind-wings is bounded (as in 

 Agathina) by the costal nervure, instead of extending suffusedly beyond 

 it, as in Poppea ; while the wide suffusion from the base of the fore- 



1 Dewitz {Nov. Act. K. Lcop.-Carol.-Dcutsch. Alcad. Naturf., xli. p. 1S5, 1879) and 

 Moschler {Yerh. K.K. Zool.-Bot. Gcsellsch. Wien, 1883, pp. 270-77) have independently 

 been at pains to point out the characters which in reality widely separate such to all 

 appearance closely allied species as Rhodoj^e, Fab., and Poppea, Cram., which authors 

 generally have treated as identical. Not only has Rhodope constantly eight hind-marginal 

 spots (instead of six) in the hind-wing, as well as other minor differences, but the subcostal 

 nervure of the fore-winy has an additional (fourth) branch. This latter distinction is actually 

 more of generic than specific value. Moschler [loc. cit., p. 270) is, however, quite in error 

 in placing the ? of my Poppea (= ? Ramus, described in 1S79) as that of Rhodop", Fab., its 

 neuration agreeing with that of the 6 with which I associated it, as well as with the neura- 

 tion of the true Poppiea, Cram., Agathina, Cram., and Phileris, Boisd.
