356 Mr. E. Trimen's descriptions of new 



Cape Colony. Mr. Peringuey informs me that this 

 individual was in company with another larger butterfly, 

 which he thinks was most probably the female, but 

 which he did not succeed in capturing.

$ . White, with black markings. Fore wing : Costa 

 edged very narrowly with black; base with a slight 

 pearly gloss ; at extremity of discoidal cell an oblique, 

 angulated, transverse streak, wider in its lower portion ; 

 a rather narrow apical and hind-marginal border (widest 

 at apex), rather sharply indenting the white on nervules, 

 ending abruptly on 1st median nervule ; at extremity of 

 submedian nervure a small spot, quite separate from 

 hind-marginal border ; immediately before border four 

 rather small spots, of which three form an oblique row 

 from costa (the 1st touching apical border), and the 4th 

 is between 2nd and 3rd median nervules and rather in- 

 distinct. Hind wing : On hind margin six nervular 

 spots, all (except that at end of submedian nervure, 

 which is small and almost linear), large, subovate, well 

 separated. Under side : Hind wing and apex of fore 

 wing pale chrome-yellow ; nervures of hind wing uni- 

 versally black. Fore wing : In upper part of cell, for a 

 little distance from base, a flush of orange ; disco- 

 cellular terminal streak fainter than on upper side, 

 commencing a little further from costa ; four sub- 

 marginal spots distinct ; apical yellow extending nar- 

 rowly to about middle of hind margin ; a hind-marginal 

 row of seven small, inwardly-acuminate, nervular, black 

 spots. Hind wing : Costa, from base to before middle, 

 edged with orange-red ; a submarginal row of seven 

 small, subsagittate, black, internervular spots, of which 

 the middle or 4th one is very small ; hind-marginal 

 spots all smaller than on upper side (except that at end 

 of submedian nervure, which is larger), narrow, sub- 

 rhomboidal, well separated ; a faint blackish dot on each
