284 Mr. R. Tiimen on some New Species 



border wide along costa and hind-margin, and very broad in apical 

 region (almost reaching extremity of discoidal cell); two spots in 

 cell, and a quadrate one closing it, all touching costal border, and 

 dark-brown ; two similar spots between 2nd and 3rd median 

 nervules, one just beneath extremity of cell, the other more or less 

 incorporate with hind-marginal border ; cilia narrow, white, in- 

 terrupted with brown. Hind-wing : costa from base widely, 

 hind-margin very narrowly, bordered with dark brown ; a fuscous 

 streak closing cell ; a sub-marginal row of blackish lunular marks, 

 more or less distinct ; anal angle prominently lobed, ferruginous- 

 red, marked with a gilded dot, bearing a short, slightly-twisted, 

 acute tail of the same hue, white-tipped, on sub-median nervure ; 

 cilia mingled greyish and ferruginous. Underside. — Forewing : 

 dull orange-yellow, very pale on inner-margin ; border varying 

 from cinereous to ferruginous-brown ; spots in and bordering dis- 

 coidal cell, transverse row of spots beyond ntiiddle, and row of dots 

 on costa, all with large, brilliant, greenish-golden centres ; below 

 median nervure, a large, dull-black, whitish-centred, gold-dotted 

 spot; a white, gold-dusted streak on bend of costal edge at base; 

 a sub-marginal row of indistinct golden dots. Hind-wing : varies 

 in tint like border of fore-wing ; three transverse rows of small 

 golden spots, some of which are indistinct, the middle row including 

 a golden streak closing cell ; a dark-brown, transverse shade near 

 hind-margin, ending on inner-margin with a golden streak. 



5 . Dull orange-yellow ; brown borders paler, narrower. Fore- 

 wing : base more widely suffused with brown, mingled with 

 ochreous ; apical border not half as wide as in ^ ; spots in and 

 about cell larger; beyond middle, a zigzag row of small, quadrate, 

 brown spots across wing. Hind-wing: base dark-brown to ex- 

 tremity of discoidal cell ; costa broadly bordered ; hind-margin 

 edged with a brown line ; sub-marginal lunular row well marked, 

 the lunules contiguous ; a more or less incomplete row of small 

 spots a liitle beyond middle, like that in fore-wing. Underside. — 

 Quite like that of $ ; rather paler ; spots larger, the gilding 

 slightly paler but not less brilliant. 



Antennae, in both sexes, marked beneath with a conspicuous, 

 broad, white bar, just at the base of the club. 



This very beautiful species plainly belongs to the Alphceus 

 section of Zer'itis, — that most characteristic South African genus 

 of butterflies. Though so much smaller, Z. Croesus seems the 

 more typical form of the two, the elbowing of the fore-wing and 

 the anal-angular lobe and tail being much more prominent than 

 in Alphceus. At the same time these very characters, conjoined
