loith hlach nervular interruptions. Fore-ioing : costal border more or 
less thickly sprinkled with blackish atoms, especially near base ; border 
rather broad at apex, usually marked exteriorly by linear inter-nervular 
ochre-yellow marks (which become continuous below third or second 
median nervule), but usually broken into separate spots below third 
or second median nervule ; above cell two or three small spots, 
in it generally two or three others centrally situated, below it two 
(of which the inner is sometimes obsolete), one on each side of third 
median nervule. Hind-wing : a spot on costa before middle ; on hind- 
marginal edge a series of minute usually sublinear nervular spots. 
Undek side. — Same colour as on upper side, hut cveryivhere, except on 
inner-7narginal area of fore-vmig, thinly sprinkled with hlackish atoms ; 
common to both wings, an irregular discal row, and a regular sub- 
marginal row of small blackish spots, and a series of minute nervular 
spots on hind-marginal edge ; terminal disco-cellular spots as on upper 
side. Fore- wing : blackish border wanting, except as slightly repre- 
sented by the spots of submarginal row, of which the lowest spot is 
much larger than the rest. Hind-iuing : four very small spots near 
base, viz., two above, one in, and one below cell ; one or two similar 
spots in cell, farther from base ; two larger spots below cell, one on 
each side of first median nervule. 
$ Like except that the spots geiierally are smaller and fainter, and 
that in fore-iuing the costal irroration is thinner, and the apical hind- 
marginal border ahnost or entirely obsolete. Under side. — As in but 
irroration fainter and sparser. 
The nearest allies of this species are P. Amenaida and P. Botha, 
Hewits., from Angola and Gaboon respectively, but both possess larger, 
differently situated spots, and a broad blackish border to both wings. 
P. Abraxas, Westw., associated by Hewitson (op. cit., p. 1 1 9) with 
Tropicalis as a variety of the ^, has every appearance of being quite 
distinct ; it is yellowish-white, with both discal and marginal spots 
large and rounded, and is recorded from several parts of Western 
Africa. 
I met with this curious butterfly not uncommonly on the coast of JSTatal in 
1867, froii^ the end of February to the end of March. It flies very slowly, 
always frequenting shady spots on the edge of woods. It is usual to find a 
good many specimens about some particular spot ; at the Itongati River I met 
with quite a company of them settled on stems of grass, and flitting deliberately 
about in an avenue just at sunset. On almost all other occasions of noticing 
this species, I took them while flying slowly in bushy places at some height 
(10 to 15 feet) from the ground. Among examples received from Colonel 
Bowker were several noted as captured near D'Urban in the months of Novem- 
ber and December. 
Hopffer (op. cit.) remarks that the three specimens ) which he describes 
from Querimba were considerably smaller than Boisduval's from I^atal, mea- 
suring only I in. i lin. across the fore-wings.
