extends rather nearer to hind-margin ; submarginal spots distinct in 
pairs throughout ; hind-marginal ochrey-yellow marks developed into 
an edging from radial nervule to inner margin a little before anal angle. 
Under side. — White markings as above, hut loitli a distinctly greenish 
gloss, in parts tiiiged with violaceous ; whitish clouding almost obsolete 
in apical area of fore-wing, and quite wanting in that of hind-wing. 
Fore-iving : discal area much darker than in Hind-wing : hind- 
margin distinctly edged with ochrey-yellow throughout, and anal angle 
suffused with that colour. 
This butterfly is a very near ally of P. Tarquinia, Trim. ; and when I had 
only seen a $ example in Mrs. Monteiro's collection in the year 1881, I did 
not think that ^it should be treated as more than a variety of the species 
named. But having now (August 1884) received both sexes on loan from Mr. 
H. Grose Smith, I find that the $ presents features so very dissimilar as to 
demand specific separation. As regards the $ , P. Delagoce is distinguishable 
by (i) the greater development and purer white of the central markings, 
(2) the better definition of the small submarginal spots, (3) the presence of 
ochrey-yellow marks at the anal angle of the hind-wing, and on the under side 
by (4) the mixture of whitish clouding in apical hind-marginal area of both 
wings, (5) the paler fulvous ochreous at base of hind-wing, and (6) the ochre- 
yellow hind-marginal and anal angular border. In the $ all these differences 
(except the whitish clouding on the under side) are emphasised ; and the con- 
trast between her and tlie^ narrowly yelloAV-banded $ Tarquinia is too great 
to need minute description. In fact, while the $ Tarquinia, as above pointed 
out, is in outline, pattern, and colouring modified in resemblance to Amauris 
Echeria, the $ 'Delagoce is decidedly imitative of A. Ochlea. The abdominal 
white spots, which are indistinct in $ Tarquinia, are conspicuous in 9 Delagoce. 
The ^ and $ here described and the above referred to are all the ex- 
amples I have seen, and all three were taken at Delagoa Bay by Mrs. Monteiro. 
It is curious that the ^ Delagoce, though in some characters farther removed 
from the West- African Lucretia, Cram., than is Tarquinia, shares with the 
former only the conspicuous feature of whitish clouding on the under side near 
the apex of both wings.

^ iuscous, with yelloiuish-white hands. Fore-wing : an oblique, nar- 
row, subapical band, tolerably even and continuous, slightly broader 
inferiorly, crossed by three nervules, extending from a little below 
costa as far as second median nervule ; on inner margin, beyond 
middle, a small space inconspicuously irrorated with yellowish-white ; 
five black spots in discoidal cell, the largest one at base, and enclosing 
a small white spot ; two rather smaller, nearer to base than to extre-
