56 RHOPALOCERA AFRICA AUSTRALIS. 



perceivable. UNDER-SIDE. Fore-wing : pale-yellow as above ; 

 apical marking deep-yellow, with greyish indications of the 

 bordering stripes ; in some specimens, a more or less distinct 

 disco-cellular dot; a row of thin black dots along hind- 

 margin, situate between the nervules. Hind-wing : chrome- 

 yellow ; disco-cellular dot always present, sometimes con- 

 spicuous; row of thin dots along hind-margin between 

 nervules, as in. fore-wing. 



$ . " Slightly smaller, almost white. Fore-wing : a rather 

 large, central, black spot; orange patch smaller, traversed 

 by a macular, sinuate, black band, which is continued across 

 hind-wing to disc, or even to anal angle. Hind-wing : hind- 

 marginal spots rather large and strongly marked. UNDER- 

 SIDE. Similarly marked to upper-side, but without orange 

 patch. 



" We have seen female specimens in which the orange patch 

 was very pale and almost obsolete" Boisd., Species General. 



The above description of the female of A. Evarne must be qualified by M. 

 Boisduval's subsequent remarks on specimens from Natal. He writes, in his 

 Appendix to M. Delegorgue's travels " Specimens that we have received 

 from the Amazoulu Country differ remarkably from those brought from 

 Dongola by Ehrenberg, which are in all respects similar to those from Sene- 

 gal. Our specimens are much larger and both male and female have a very 

 brilliant sulphur-yellow ground-colour. The pattern on the wings of the 

 female is also much more strongly marked than in the same sex from Senegal 

 and Dongola." 



This warmly-tinted species is one of the loveliest of the beautiful Genus 

 to which it belongs. In structure it seems to approach nearer to the Euro- 

 pean type of the Genus than most of the other African species Q[ Anthocharis. 

 It appears to me by no means uncommon in the Natal district, but I have 

 never yet seen the female. 



By its bright-yellow,* instead of white, ground-colour it may at once be 

 distinguished from the other South African species of the Genus. The next 

 species, A. subfasciata t however, is described as possessing a yellow-tinted 

 surface, but it would seem to be considerably paler than in Evarne.
