has no dusky stripe along the inner margin of the fore wings, but 

 a male taken in Mashuna-land by Mr. F. C. Selous has a faint

c? . Anthocharis antigone, Boisd. op. cit. p. .572. n. 19 (1836). 



Ehanda (September). One male example. 



This specimen has all the blackish markings faint and reduced ; 

 the inner-marginal stripe of the fore wings is represented only by a 

 very indistinct spot beyond the middle. 



9S. Teracolus phlegetonia (Boisd.). 



(J. Anthocharis phlegetonia, Boisd. op. cit. p. 576. n. 2.t 

 (1836). 



Omaramba-Oamatako (January). Seven examples ; three males 

 and four females. 



A good deal of variation in size is shown by these males ; the 

 smallest lias the inner-marginal black stripe of tlie fore wings 

 relatively mucli reduced. In the females the spots in the apical 

 patch of the fore wings vary in tint from dull reddish to dull 

 yellowish grey. 



99. Teracolus theogone (Boisd.). 



(5 $ . Anthocharis theogone, Boisd. op. cit. p. 575. n. 23 (1836). 



Ehanda (August-September) and Humbe (October). Two male 

 examples. 



There is no trace in either of these specimens of any longitudinal 

 blackish markings on the upperside. 



Genus Callidryas, Boisd.

2 . Papilio florella, Fabr. Syst. Ent. p. 479. n. 159 (1775). 



Ehanda (September), Omrora (November), Otiembora (November- 

 December), and Okavango River (December). Six male examples. 



Mr. H. L. Feltham's observation \ that the males of this butterfly 

 that appear early in the season are all less distinctly freckled and 

 hatched on the underside than those of the midsummer and autumnal 

 brood, was borne out by specimens which he sent to me, and re- 

 ceives further confirmation from Mr. Eriksson's examples. I noted 

 that Mr. Feltham's specimens (from Griqualand West) presented 

 the further peculiarities of smaller size {exp. al. 2 in. 25-6 lin.) and 

 a yellower tint on the underside ; and all three distinctive characters 

 are presented by Mr. Eriksson's Ehanda male. The Omrora ex- 

 ample (November) is also but faintly marked on the underside ; 

 the one from Otiembora is larger and more distinctly marked ; and 

 the two taken on the Okavango Eiver in December are full-sized 

 and strongly marked beneath.
