Natal. 
The wet-season form of this local representative of J’. phle- 
gyas comes nearer to TZ’. done, only the male has a very 
strongly defined blackish stripe across the under surface of 
the secondaries ; the female has the subapical white spots 
small and greyish in colouring and the basal area very dark, 
whilst the bar on the secondaries is more strongly marked 
and the spots of the marginal border extend further up the 
nervures. ‘This is the 7. natalensis of Staudinger *. 
The dry-season form is representel by 7. Buztoni, of 
which we only possess a pair in the general series, but of 
which there are four others in the Hewitson collection. In 
this form the upper surface of the male resembles that of the 
wet-season type of 7’. 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 Mr, Trimen, that no Europeans lived in Natal 
when this species was described, is insufficient evidence to 
authorize the application of the name 7’ zone to a species 
which does not at all answer to M. Godart’s description. 
This is the only species which can be correctly described as 
“anticis supra apice (medio violaceo) nigris,” which M. Godart 
further explains thus :—“ Les premiéres ont 4 l’extrémité une 
bordure noire arquée, étroite vers langle interne, large vis-a- 
vis du sommet, ot elle est divisée transversalement et oblique- 
ment par une bande violette, trés-brillante, arrondie en 
dehors.” ‘he description of the under surface of the hind 
wings with “ some blackish marginal dots” is not applicable 
to T. jalone or any of the forms of 1’. phlegyas, but only to. 
* This author, judging me by himself, makes some quite uncalled for 
remarks about 7. jalone and T. jobina. Considering that I had three or’ 
four collections at my disposal when I described them, it would be odd if 
his statements were true.
