PIERID^. 81 



The above description of llie ? insect is that of a specimen taken ia 

 Damaralaud by Mr. C. J. Audersson, wliich quite accords with M. Bois- 

 duval's description and witli Cramer's figure, excepting that the black border 

 on hind-margin, with the interruption mentioned, extends to anal angle. I 

 give the species as an inhabitant of Africa South of the Tropic on the 

 authority of M. Boisduval, who includes it in his list of Lepicloptera col- 

 lected by M- Delegorgue. In his " Species General," the same author 

 remarks that T. Brigiita is " probably only a local variety of 2\ Drona." 

 The whole Genus Terias, presenting so many very closely-allied forms, de- 

 mauds the careful investigation of entomologists.

Since the above was written, Mr. J. H. Bowker has for- 

 warded to the South African Museum a ? specimen of T. 

 Brigitta, taken in Kaifraria, — so that there is no longer any 

 doubt as to its being really an extra-tropical South African 

 species. In Mr. Bowker's specimen, the band bordering 

 fore-wing quite agrees with Cramer's figure, — the spot at ex- 

 tremity of submedian nervure being small and inconspicuous.

In the same collection as the female specimen just mentioned, 

 and from the same locality, Mr. Bowker forwarded two 

 male Terias, which I have little doubt are true Brigitta, as 

 they accord with the brief description I have quoted from 

 Boisduval's " Species General," with the exception of posses- 

 sing blackish atoms at base oi fore-wing. I add the follow- 

 ing description of these specimens 



$ . Expands 1 in. 8 lin. — 1 in. 9 lin. 



Bright gamhoge-yellotv. Fore-wing : base dusted with 

 blackish ; on costa, close to base, some blackish atoms, rapidly 

 darkening into a narrow black border, which gradually widens 

 to apical portion, where it is nearly as broad as in T. Rahel, 

 and whence it narrows to anal angle, — interrupted, however, 

 by the yellow ground-colour between third median nervule 

 and submedian nervure ; the yellow interrupting portion 

 dusted with blackish ; three minute yellowish streaks indenting 

 the border on costa near apex. Hind-wing : the black border 

 on hind-margin much narrower than in Rahel, (in one speci- 

 men very narrow, and simply macular beyond discoidal 

 nervule), not extending beyond third median nervule. 

 Underside. — Quite like that of the ? Brigitta ; but the 

 orange-yellow colouring of both wings considerably paler, the 

 irrorations more scattered, and the spots near base of hind- 

 wing not ocellated. Fringes yellow, pink-tinged above and 

 below.* 



* Mr. D'Urban has taken both sexes of T. Brigitta^ and gives me the 

 following note of the species : " Graham's Town and King William's Town ; 

 February and April. Common." g
