33^ SOUTH-AFEICAN BUTTEEFLIES. 



green, but the white dorsal spot was circled with light-blue. (This 

 larva does not appear to have been described by Captain Harford in its 

 final stage.) 



Pupa. — Bright-green ; spiracles reddish-brown ringed with white, 

 diminishing in size towards last segment ; projections of head tipped 

 with white ; some confluent white spots on wing- covers. Head rather 

 acutely bifid ; thorax very convex ; wings forming slight lateral pro- 

 jections ; abdomen making a great angle at the segment in a line with 

 apex of wing-covers, the last segment prolonged into a pedicel bearing 

 four tubercles. (H. C. Harford, MS. notes on Natalian pupa, 1869.) 



The white band towards costa of fore-wing becoming so attenuated 

 and markedly macular, on the upper side, readily distinguishes Brutus 

 from its South- African congeners ; while the under side is in colouring 

 and pattern intermediate to a great extent between those of Druceanus 

 and Saturnus. 



I frequently met with this fine Charaxes at Port ISTatal, and managed to 

 capture a good many specimens at the " sucking-places " (on stems or branches 

 of trees where moisture exuded) so specially attractive to butterflies of this 

 group. On the wing, Brutus is one of the very swiftest of ISTymphalidse, and 

 it is difficult to follow its flight, except when it is chasing another of its species 

 or some competitor at the drinking stations mentioned. I noted examples 

 in February, March, and April, and Colonel Bowker took several in August 

 in the same locality ; while in Kaffraria he had noticed the butterfly's occur- 

 rence in March, May, and June.
