64 Mu. R. trim:es on butterfites from [Jan. 16, 



In my S.-Afr. Butt. iii. p. 42, I noted the apparent absence 

 of any female examples linking the var. flavida, Mab., with the_ 

 tvpical female ; but I have s^ince then received two intermediate 

 gradations from Durban, Xatal. In the first of these, taken by 

 Mr. C. W. Morrison on the 16th May, 1S!»0, the ground-colour is 

 tinged ^nth lenion-yellon', the hind-marginal border of the hind 

 wings is very little broader than in the variety, but the basal 

 blackish in the fore wings, instead of being merely a narrow costal 

 border, fills all the discoidal cell except its lower edge, where it 

 becomes a sparse irroratiou only. In the second, taken by Mr. A. 

 D. Miller, there is more approach to the typical female, the hind- 

 marginal border of the hind wings being broader, and the basal 

 black in the fore wings filling the cell, but not extending below it 

 except in a very faint and narrow inoration at the base, while the 

 only tinge of yellow on the white area is at the base of the hind 

 wings.

A male and a female very much worn, taken at Sarmento, on 

 the Pungwe Eiver, on the 18th September, are apparently referable 

 to this species. 



119. PlERIS SISIANA, Hopff.

 t. xxiii. figs. 3, 4 (1862). 



The only specimen, a female taken at Christmas Pass, has the 

 fuscous apical border in the fore wings widened so as to include 

 the subapical costal streak, and the fuscous hind-marginal spots in 

 the hind wings also larger than usual. 



120. PiERis SETEEixA (Cram.). 



2 . Papilio severina. Cram. Pap. Exot. iv. pi. 338. figs. G. H 

 (1782). 



Fourteen specimens, 4 males, 10 females ; twelve from Christmas 

 Pass, where the paired sexes were captured on 26th February, 

 Though varying a good deal in depth of markings, all these ex. 

 amples belong to the larger form with more brightly-tinted under- 

 side, which 1 have shown (S.-Afr. Butt. iii. p. 72 & note) to be 

 in Natal characteristic of the summer or wet season.
