SOUTH-ArKICAN BUTTERFLIES. 
tible) narrow sjiots near costa, so that hdiuecn long suh-hasil stripe and 
siibmargmal lumdcs there is a hroad unhroJcen area of hlack ; sub- 
marginal lunules rather large, — the first (on costa) white, the fourth 
obsolete inferiorly, the fifth obsolete, the sixth (last) sometimes obso- 
lete, but occasionally linear and distinct ; a little hcfore this last lunule 
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-broivn, rather darker than in Porthaon, ivith a hronzy gloss ; greenish 
markings as on nfpcr side, hut paler and rather broader, and icith rather 
Uurred edges, especially common basal and suh-basal stripes. Hind- 
iving : crimson-red marks of central series arranged generally as in 
Policenes, 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 Porthaon ; 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 Poli- 
ccnes and Portha.on ; 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 $ Porthaon. 
Described from specimens (only one $) collected at Delagoa Bay 
by Mrs. Monteiro. In my figure of a <J (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 P. Policenes and P. Porthaon, 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 P. 
Anthens and P. Evombar. As Mr. Oberthlir has remarked {Etudes 
d'Pnt., liv. iii. p. 15, 1878), the black field of the hind-wiugs. 
approximates this butterfly in aspect to the otherwise not remotely 
allied P. Philolaus, Boisd., 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 Porthaon.
