and inner-margin ; spots as in $ . In specimens having the 

 upper- side of hind-wing yellowish, the underside is rich, 

 deep chrome-yellow, with the spots larger than in ordinary 

 specimens, and sometimes united along hind-margin. 



I have not seen a South African specimen of P. Calypso, but include 

 the species in my list on the authority of Boisduval, who gives Natal as its 

 habitat. I made the above description from fine West African examples 

 in the British Museum. It may be known from the other species found 

 in South Africa by its larger size.

$ . White, with blackish markings. Fore-wing: hase 

 narrowly greyish ; costa narrowly edged with blackish ; at 

 extremity of discoidal cell, a rather broad, short, blackish 

 stripe, extending above sub-costal nervure, but not touching 

 costal edge ; a broad, blackish stripe on hind-margin, abruptly 

 terminating on 2nd median nervule, and containing 4 rounded 

 white spots, the 3rd of which, from costa, is commonly con- 

 nected with the white ground-colour of wing, dividing the 

 band into 2 portions. Hind-wing : on hind-margin a row of 

 black dots, one at extremity of each nervule. UNDER- 

 SIDE. For.e-wing : as on upper-side, but disco-cellular 

 stripe extended to costa by some fainter blackish colour- 

 ing ; apical portion of hind-marginal band tinged and dusted 

 with chrome-yellow. Hind-wing : nervures much clouded 

 with yellow-dusted grey, leaving a central, transverse, curved 

 band of white, and forming a row of five or six white 

 spots on hind-margin ; costa at base, and most of the spaces 

 between clouded nervures, tinged with bright chrome-yellow. 



? Similar to $ , but with additional black markings. 

 Fore-wing: costa with a greyish border as far as disco- 

 cellular band, which is much broader than in $ ; hind- 

 marginal band slightly broader and blacker than in $ ; its 

 third white spot always quite enclosed in the black ; two ad- 

 ditional blackish spots near anal angle, between third median
