SOUTH-AFRICAN BUTTERFLIES. 
antennae black, ringed beneath with white. Thorax black above, here 
and there tinged with blue ; breast and legs white. Abdomen black 
above, white beneath. 
$ Bather dull pale-hlue ; horclers fuscous in fore-wing^ fuscous-grey 
in hind-iving. Hind-wing : a discal transverse interrupted fuscous 
streak extending from second subcostal nervule to first median nervule ; 
two black spots near anal angle enlarged and with large orange-fulvous 
centres ; a similar brighter spot, inferiorly blue-scaled on anal angular 
lobe. Under side. — Hind-wing : anal-angular spot more crimson than 
fulvous. 
The above description of the $ is adapted from "Wallengren's, as I have 
not seen an example of that sex.^ The 9 agrees with it in all respects except 
those just noted. 
In tint of blue, /. Trimeni $ appears to resemble /. Sidus, to which species, 
as regards form, Wallengren compares it. In its large size, however, and 
very feebly-marked under side, Trimeni is much nearer to Silas, Westw. ; 
but the $ appears to want the crimson upper- side spots near the anal angle 
of the hind- wing, while the $ 's orange spots are very much less developed ; 
and on the under side the red transverse discal streak is wanting in both 
wings. 
This appears to be a rare species. The single specimen received by 
Wallengren is noted as having been taken in December on the crest of a 
mountain on Schoman's Farm near the Yaal River. The $ here described 
and figured was sent to me in 1873 by Mr. H. Barber, who took it in some 
part of the Transvaal, but made no note of the particular locality.

$ Soft pale line; apical half of fore-wing hlach ; circular costal 
patch on hind-wing large, conspicuous, glistening-whitish, broadly 
ringed with blackish. Fore-ioing : costa grey, edged with pale-reddish 
near base, abruptly widening and deepening into apical black before 
extremity of discoidal cell ; blue forming an imperfect semicircle, having 
for its base the inner margin of wing, but not reaching anal angle, to 
which the apical black (covering the entire hind-margin) narrowly 
extends. Hind-iuing : hind-margin edged with a black line ; three 
tails precisely as in Silas, but less twisted ; inner-marginal groove 
dark-grey, clothed and fringed with whitish hairs ; lobe of anal angle 
^ Though " ? " is printed in Wallengren's description, it is certain, from the mention of 
the circular costal spot of the hind-wings, that the i was intended.
