A second group of the same type was captured in the 

 same locality on March 30, T897, and consists of six 

 individuals : — 



L. chrysippics ^. 



IT. misippus $, a pale patch in the centre of each hind- 

 wing. 

 F. cschria ^, buff sub-apical bar to fore- wing. 

 A. encedon $. 

 A. Serena, var, huxtoni %. 

 A. iKtraia %. 



The lack of correspondence between the varieties of the 

 females of H. misippus and those of the central member of 

 the group is well seen in these two sets. Thus one of the 

 three females is the inaria form, although the I'luf/ii var. 

 of chrysijrpus is almost unknown in S. Africa, wliile the 

 other two suggest the appearance of the aJrippoides var., 

 which does indeed occur not uncommonly, but is not 

 nearly so abundant as typical chrysi2')pus. The female of 

 A. pctrma is another outlying member of the group, while 

 the male is altogether outside it. 



A third group, captured by Mr. Marshall at Salisbury on 

 April 10, 1898, contains these species: — 



L. chrysippus $ ^ 



H. misip)pus $ \ all typical forms. 



2 A. encedon $ J 



A fourth group captured at the same locality on April 

 9, 1899, contains : — 



2 L. chrysip)pus $ , $ (Plate XIV, figs. 1, la). 

 2 Mimacrfea rnarshalli $ (Plate XIV, figs. 2, 2«). 



This beautiful Lyctenid mimic presents in some respects 

 a closer approximation to Acram encedon (Plate XIV, figs. 

 3, 3ft) than to L. chrysip)pus, the primary model of both. 

 Thus the character and contour of the sub-apical white 

 bar of the fore-wing suggests that of the Acrsea rather 

 than the Danaine. In the two former the bar is more 

 continuous, in the latter more obviously broken into dis- 

 continuous spots, attended by outlying smaller spots. 

 Another far more important similarity between Lyccenid 

 and Acraia is brought about by the numerous conspicuous 

 black spots which in both are scattered over the basal part 

 of the under-side of the hind-wing. In other respects the
