fading outwardly into yellow, in basal region ; six liind-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 hcfore apex 
at end of second subcostal nervule. Hind-iving : 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 tmiversally suffused tvith pale creamy-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 Fore-wing : 
apical fuscous crossed by two or three ochreous inter-nervular rays ; a 
minute spot at extremity of submedian nervure. Under 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-marginal ly 
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 
Popped, Cram.,^ and of the Malagasy Phileris, Boisd. ; it is, perhaps, 
not quite so closely allied to AgatJiincc, Cram. As far as the $ s are 
concerned, the ve7y conspieuoiis orange-red hasal suffusion of the fore- 
wings on the upper side readily distinguishes Eilpipellii from all the three 
species named ; Bhodope 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 binder side, Bilpp)ellii 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-

Moschler {Verh. 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 Fthodoj^e, Fab., and Poppea, Cram., which authors 
generally have treated as identical. Not only has Rliodope constantly eight hind-marginal 
spots (instead of six) in the hind-wing, as well as other minor differences, but the sichcostcd 
nervure of the fore-wing 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 { = ? Ilcemus, described in 1879) as that of Rhodopc, Fab., its 
neuration agreeing with that of the S with which I associated it, as well as with the neura- 
tion of the true Poppea, Cram., Agathina, Cram., and Phileris, Boisd,
