' rather fcdcli hefore middle.) Forc-iving : the following white spots, 
' viz., in discoidal cell, not far from extremity, and adjoining subcostal 
! nervure, a short oblique white mark of variable size and shape (but 
always much smaller than in F. Cenea, and sometimes almost obsolete) ; 
' beyond cell a short oblique subapical bar crossed by upper radial ner- 
j vule ; a large ovate spot below cell, between second and first median 
: nervules (its upper edge sometimes extending beyond second median 
nervule) ; a subapical hind-marginal spot as in ^, but very much 
j larger ; and a submarginal series of four similar spots between first 
: radial nervure and submedian nervure. Hind-wing : central band or 
' patch (rarely dull yellowish-white) considerably wider than in ^, 
j except costally (where it is much narrower) and inner-marginally 
■ (where it is rather narrower), — its inner edge being nearer base, and 
' its outer edge much more rounded ; hind-marginal spots white, larger 
\ than in the lower ones usually not quite so close to marginal edge, 
' and sometimes a small additional spot close to anal angle. Under 
SIDE. — As in except for the totally different white marks of the fore- 
\ wing^ which agree with those of the upper side, hut are rather larger. 
Fore-wing : uppermost spot of submarginal row of four obsolete. 
Hind-iving : basal ochreous-yellow narrower than in $ ; some indistinct 
greyish-white scaling between discal white spot and third spot of hind- 
' marginal row ; of the latter the second and fourth spots are often very 
small and obsolescent, and rarely wanting altogether. 
In the dwarf ^ above noted, all the usually white spots are of the 
■ same pale ochreous-yellow as the hind-wing patch, except that the 
marginal ones are rather paler. 
Head and body marked and coloured as in $, except that the sides 
j and back of abdomen are not so dark. 
i As regards the $ P. Fcherioiclcs differs from its near ally the 
\ "West-African F. Cynorta, Fab. {Zeryntius, Boisd.), as follows, viz. : ( i ) 
' The macular band of the fore-iving is much narrower, its inner edge 
■ being at some distance from discoidal cell, and its outer edge much 
farther from hind-margin; (2) this band is uninterrupted, the sepa- 
rate spots gradually widening from its origin, while in Cynorta it is 
abruptly interrupted, the second spot being absent or quite obsole- 
scent, and the third very large; (3) the outer contour of the band is 
' slightly concave instead of convex, and the component spots are nar- 
rower and less blunt internally, the separating black rays being 
; broader ; (4) in the hind-wing, the continuous band is usually nar- 
j rower, its inner edge being further from the base, while its outer edge 
IS almost even, instead of being sharply and regularly dentated by the 
mter-nervular rays; and (5) the hind-marginal spots are a conspicuous 
difference, being either very small or (oftener) altogether wanting in 
Cynorta. On the under side, in the fore-iving, (6) the inner edge of 
the band is rather farther from the discoidal cell than it is on the 
upper side, whereas in Cynorta it is so close as partly to touch the
