294 SOUTH-AFRICAN BUTTERFLIES. 



the upper ; and two, smaller than the two central ones, still more 

 obliquely placed at outer end of. cell, the lower being on second disco- 

 cellular nervule ; two small black spots just below cell, one at base, 

 immediately preceded by a white dot, the other about as far from base 

 as second cellular spot ; a bluish-bronzy gloss along costa and over 

 basal and inner- marginal region, strongest on inner-marginal edge. 

 Hind-wing : a rather broad, central, transverse band, rather straight, 

 and of even width except near costa, where it is rather narrowed and 

 obscured ; a good-sized black spot at base, marked (on origin of median 

 nervure) with a whitish dot, and surmounted towards costa by a whitish 

 spot ; two black spots obliquely placed in discoidal cell near base ; 

 two above cell, one on each side of first subcostal nervule ; one imme- 

 diately below cell, close to base ; one (small and thin) on the almost 

 atrophied nervule closing cell ; and one (minute) just outside cell above 

 the radial nervule ; the two spots last mentioned are within the white 

 transverse band. In both loings inter-nervular black rays extend from 

 hind-marginal edge to exterior of white band, in hincl-iuing piercing 

 the band to some depth. Undek side. — Much 'palcr ; outer hahes of 

 ivings ochreous-grey ; spots near base as on upper side, but much more 

 conspicuous ; pale bands with less distinct outline, that of hind-wing 

 narrower ; in each wing an additional white spot at origin of costa. 

 Fore-iving : innei'-marginal whitish space more apparent, but still ill- 

 defined ; a faint basal tinge of fulvous below cell. Hind-wing : all the 

 basal ground-colour before transverse band ferruginous-fulvous, with a 

 faint violaceous gloss. 



Antennce black ; ^ja/jj-i black above, laterally and beneath yellow ; 

 head, thorax, and base, broad dorsal line, and segmental incisions of 

 abdomen black. Head with six white spots (two on front, two on 

 summit, and two behind the eyes) ; collar with two ; thorax with 

 eight ; base of abdomen with two ; breast with one central white spot, 

 and two yellowish spots on each side ; legs brown, with a white spot at 

 base of each femur, except first aborted pair, which are yellowish. 

 Abdomen with sides and under-surface ochre-yellow. 



The species is nearly allied to P. Hirce, Drury. (See Mr. He wit- 

 son's figure of the typical form of the $ Hirce {Eurytus, Clerck), from 

 Calabar.^) It may, however, be readily distinguished from the latter 

 by the absence in the fore-wings of the conspicuous white band which 

 in the $ Hirce extends from the inner margin towards the subapical 

 band ; and by the fuscous base of the hind-wings, which in the $ Hirce 

 is occupied by the white of the band. In F. imitator the subapical 

 band of the fore-wings is much longer and narrower, and the second 

 and third cellular spots are in all the wings nearer to the base. 



The above description was made from the only two specimens (both $ ) 

 then known to me. I have since received from Colonel Bowker the follow- 

 ing Natalian examples, viz., a $ in 1878, whose locality was not recorded, it
