2IO SOUTII-AFRICxiN BUTTERFLIES. 



tible) narrow spots near costa, so that hdicccn long sub-las d stripe and 

 sidjmarginal lunidcs there is a broad unbrolen area of blach ; sub- 

 marginal lunules rather large, — tlie first (on costa) white, the fourth 

 obsolete inferiorly, the fifth obsolete, the sixth (last) sometimes obso- 

 lete, but occasionally linear and distinct ; a little before tluis last lumde 

 a crimson-red one, variable in size; also a crimson-red rather small 

 spot at anal angle ; basal half of tail black, outer half white, with a 

 black median streak and thin black edges. Under side. — Glistening 

 didl-brown, rather darker than in Forthaon, witJc a bronzy gloi>s ; greenish 

 markings as cm upper side, but pieder and rather broader, and luith rather 

 Ihored edges, cspecicdly eommon based and sub-based stripes. Hind- 

 u-ing : crimson-red marks of central series arranged generally as in 

 Foliecnes, but much more irregularly placed and completely separated, 

 their inner white edgings fainter, but their outer black borders greatly 

 enlarged into spots much broader than in Forthewn ; of these red 

 marks, the fourth or the fifth (at extremity of discoidal cell and imme- 

 diately beyond it respectively) is occasionally obsolete, and the seventh 

 (lunulate and white-edged both inwardly and outwardly) is far beyond 

 anal-angular red spot, instead of contiguous to the latter, as in Foli- 

 cenes and Forthaon ; on costa, about middle, immediately beyond outer 

 black border of second crimson mark, an ill-defined whitish transverse 

 streak, — sometimes a similar smaller streak beyond third mark, — rarely 

 similar fainter spots beyond fourth and fifth marks ; sub-basal stripe 

 broader, shorter, blunter at extremity ; submarginal lunules larger ; 

 each inwardly bounded by a large ill-defined black spot ; succeeded by 

 a hind-marginal series of thin sublinear lunules. 



Abdomen black dorsally and laterally, hoary-grey beneath ; on 

 each side a series of five or six oblique creamy-white streaks, conspi- 

 cuous on the black ground. 



$ Like ^, but ground-colour not so deep a black ; basal stripe of 

 hind-wing enlarged as in ^ Forthaon. 



Described from specimens (only one $) collected at Delagoa Bay 

 by Mrs. Monteiro. Li my figure of a ^ (Plate XL) the green of the 

 markings is given of too yellowish a tint, the actual colour in nature 

 being decidedly glaucous. Though in many respects closely allied both 

 to F. Folicencs and F. Forthewn, the singularly different direction and 

 reduced development of the discal macular band in the fore-wings, and 

 its total or nearly total suppression in the hind-wings, very markedly 

 separate Colonna from both those species, and still more from F. 

 Antheus and F. Fvombar. As Mr. Oberthiir has remarked {Etudes 

 cVEnt., liv. iii. p. 15, 1878), the black field of the hind-wings 

 a])proximates this butterfly in aspect to the otherwise not remotely 

 allied F. FidloUius, Buisd., of Northern and Central America ; but in 

 the latter the common discal band is continuous and normal in position 

 as regards the fore-wings, and in the hind-wings superiorly developed, 

 much as in Forthaon.
