after examination of a large number of examples from various quar- 
ters, I can but consider the only known species of this genus, viz., 
H. Uriphict, Godt. This butterfly has a very wide range in Tropical 
Africa, and in the south is of pretty general distribution, except in 
the south-west of the Cape Colony.

$ White or creamy-ivhite^ with hroad hlack stripes and borders; 
about eqtcal areas of blaeh and lohite. Fore-wing : a broad black band 
from base occupies all discoidal cell, extending considerably below and 
beyond it, and united by a narrower extension to a broad border on 
hind-margin ; the latter containing five variously-shaped white spots 
(of which that next costa is very small, the second, third, and fifth of 
moderate size, the fourth large and ovate), and so widened on inner 
margin as to occupy the outer half of it ; sometimes in black discoidal 
cell a paler or whitish longitudinal streak. Hhid-wing : a transverse 
black stripe at base ; before middle a black stripe, with two or three 
irregular indentations on its edges, straight across wing from costa 
near apex to about middle of inner margin ; from commencement of 
this band all along hind-margin to anal angle a black band — abruptly 
widened, and with a straight inner edge parallel to the band before 
middle, from discoidal nervule to inner margin — containing six good- 
sized white spots. Cilia yellowish-white. Under side. — Fore-wing : 
black markings clouded with white near inner margin, and along upper 
part of discoidal cell, dull and brownish tinted in central portion, and 
replaced by grey-dusted ochreous at apex ; in discoidal cell, a broad lon- 
gitudinal yellowish- white stripe. Hind-iuing : costa, especially near 
base, edged with orange-yellow ; basal, mediaii^ and hind-marginal 
bands dark-grey -dusted ochreoiis ; median band more irregular and 
macular than on upper side ; s^^ots on hind-margin larger, but not so 
clearly defined ; neuration yellowish-white. 
$ Similar to $, but commonly loith the ground-colour tinged ivith 
sulphur-yellow ; the black markings duller, and sometimes tinged ivith
