Till.' wL't-season form of this local rc|)resentatlve of T. phle- 

 gyas comes nearer to T. tone, only the male has a very 

 strongly detincJ blackish stripe across the under surface of 

 the secondaries ; the female has the subapical white spots 

 small and greyisli in colouring- and the basal area very dark, 

 w hilst the bar on the secondaries is more strongly marked 

 and the spots of the marginal border extend furtiier up tho 

 nervures. This is the T. natalensis of Staudinger *. 



The dry-season form is repre.sente 1 by T, Buxtoni, of 

 wliich we only possess a pair in the general series, but of 

 which there are four others in the Ilewitsou collection. In 

 this form the upper surface of the male resembles that of the 

 wet-season type of T. phlegyas^ but the female nearly ap- 

 proaches the dry-season form of the same.

I quite agree with Mr. Marshall that the argument used 

 by my friend ^Ir. Trimen, that no Europeans lived in Natal 

 when this species was described, is insufficient evidence to 

 authorize the application of the name T. ione to a species 

 which does not at all answer to M. Godart's description. 

 This is the only sjDecies which can be correctly described as 

 "anticis supra apice (medio violaceo) nigris," which M. Godart 

 further explains thus: — " Les premieres ont a I'extr^mite une 

 bordure noire arquee, dtroite vers I'angle interne, large vis-a- 

 vis du sommet, oiielle est divisee transversalement et oblique- 

 ment par une bande violette, tr^s-brillante, arrondie en 

 dehors." The description of the under surface of the hind 

 wings with " some blackish marginal dots" is not applicable 

 to 2\ jalone or any of the forms of T. fMegyas^ but only to 



* This autbor, judging- uie by himself, makes some quite uncalled for 

 remarks about T. jalone. and T.jobina. Considering tbat I had three or 

 four collection-! at my disposal wheu I described them, it would be odd if 

 bis statements were true.
