Ea-p. al., iih; lin. — i in. 



Black spotted with white ; the spots in numhcr and arrangement 

 quite as in P. Vindex, hut mostly smaller, and very sharply defined ; 

 the median hand of hind-winy narrov.ier, interrupted inferiorly and 

 denticulate externally. Under side. — ITind-winy : the suh-hasal and 

 central white stripes rather narrou\ not ohliqus, intcrrup)ted more or less 

 markedly in, two places, viz., the former on costal and median uervures, 

 and the latter on second subcostal and first median nervules ; of the 

 separate spots or portions of the stripes, the largest is the middle one 

 of the central stripe, which is dcntindatc hoth inwardly and outwardly, 

 hut much more stronyly outwardly. 



It is doubtful whether this form should be regarded as a species 

 distinct from Vindex, for the characters above indicated, though well- 

 marked through a good series of specimens from different localities, 

 are less distinctly expressed in three examples that I captured at 

 Eerste Eiver, — one of which has the upper side discal spots of the 

 fore-wing as large as in ordinary Vindex. 



Colonel Bowker found Mafa pretty numerously in Basuioluud, but else- 

 where it appears to be rather scarce, though with a wide distribution through 

 the interior, and especial!}^ the North-Eastern districts. Tlie few specimens 

 that I have noticed in life were on the wing during September, with the 

 exception of one which I took at Grey town in Natal on the 15 th March.
