SOUTH-AFRICAN BUTTERFLIES. 
coidal cellj but is rather widely bordered with black costally (most 
widely beyond extremity of discoidal cell), and outwardly from third 
median nervule to anal angle; ferruginous patch occupying hind- 
margin from apex to submedian nervure, irregularly convex inwardly, 
very broad on discoidal nervules, narrowing abruptly at apex, but more 
gradually to its lower extremit}^. Hind-iuing : blue fills entire disc 
and discoidal cell, and is bordered to a moderate width with black alonsr 
costa and hind-margin (the apical portion being broadest, and the 
hind-marginal narrowest) ; inner-marginal border broadly fuscous up 
to third median nervule, but blue-scaled along submedian nervure ; 
anal-angular lobe and tail ferruginous, densely grey-scaled ; edging 
base of lobe superiorly, and sometimes extending for a little distance 
along hind-margin, a fine streak of blue scales ; on lobe a spot of 
unirrorated ferruginous. Under side. — Ferruginous-hrown, in most 
parts very finely and densely irrorated with yellowish and grey scales ; 
in both wings (better defined in hind-wing) an ochreous-yellow line 
closing discoidal cell, and a transverse streak of the same colour beyond 
middle. Fore-iuing : the streak only extends from near costal edge to 
between third and second median nervules ; costa thinly edged with 
yellow ; a conspicuous cloud of yellow scales occupies costa between 
streak and apex ; inner margin pale-grey, gradually fading into ground- 
colour superiorly ; hind-marginal border darker ferruginous, not (or | 
very thinly) irrorated. Hind-iuing : darker ferruginous before trans- ; 
verse streak ; the streak itself well defined, continuous from costa to | 
below first median nervule, where it is slightly broken and abruptly || 
angulated, and is thence luldte to inner margin and along its edge to 
base ; between this portion of the streak and anal angle, dense greyish- 
white irroration ; a thin greyish line along hind- margin, indistinct | 
superiorly ; spot on lobe conspicuous, tinged with crimson. 
^ Blue much less hrilliant ; its area much smaller , so that its black- | 
bordering is broader, especially in hind-wing, where, in apical region, 
this is wider than inner-marginal fuscous. Hind-wing : hind-marginal | 
streak of blue scales more marked, extending to third median nervule 
or a little farther. Under side. — Quite as in ! 
This Myrina is recognised at once from its congener, the West- 
African M. Silenus, Fab. (Alcides, Cram.), by (i) the greatly-enlarged 
field of line, and (2) the ferruginous bar along hind-margin of fore- 
wings from apex. Judging from Cramer's figure {Pap. Exot. i. t. 96, | 
D, e), M. Silenus has only a slightly paler fascia near the hind-margin 
of the fore-wings, with no trace of ferruginous ; and the under side is 
generally much darker than in M. ficedula, and without yellowish 
clouding. Boisduval's figure purports to represent Loxura Alcides 
from Guinee ; " it is evidently that of rather a small ^. In pattern 
and colouring (only the upper side being depicted) it agrees fairly with 
the Southern form, except that along hind-margin the ferruginous 
border has a narrow black-edging, and that the outline of the hind-
