riEUIN/E. 77 



after oxaraiuation of a largo nunihor of examples from various quar- 

 ters, I can but consider the only known species of this genus, viz., 

 H. Eriphia, Godt. This butterfly has a very wide range in Tropical 

 Africa, and in the south is of pretty general distribution, except in 

 the soutli-west of the Cape Colony.

$ White or crcamy-ivMte, luith hroacl black stripes and borders; 

 about equal areas of black and ivhite. Fore-ioing : 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 ividcncd on inner 

 viargiii as to occupy the outer half of it ; sometimes in black discoidal 

 cell a paler or whitish longitudinal streak. Hind-iving : 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 — abniptly 

 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-iving : 

 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-iving : costa, especially near 

 base, edged with orange-yellow ; basal, median, and liind-margincd 

 bands dark-grcy-dusted ochreous; median band more irregular and 

 macular than on upper side ; spots on hind-margin larger, but not so 

 clearly defined ; neuration yellowish-white. 



$ Similar to $, but commonly loith the groimd-coluur tinged with 

 sulphur-yelloiv ; the black markings duller, and sometimes tinged with
