NYMPHALIN.^. 293 



extends rather nearer to hind-margia ; 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 marlcings as above, hut ivith a distinctly greenish 

 gloss, in parts tinged with violaceous ; whitish clouding almost obsolete 

 in apical area of fore-wing, and quite wanting in that of hind-wing. 

 Fore-wing : 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 5 all these differences 

 (except the whitish clouding on the under side) are emphasised ; and the con- 

 trast between her and the narrowly yellow-banded $ Tarquinia is too great 

 to need minute description. In fact, while the $ Tarqiii)na, 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 5 Tarquinia, are conspicuous in 5 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 Avhitish clouding on the under side near 

 the apex of both wings.

$ luscous, with yelloioish-ivhite lands. Fore-ioing : 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- 

 mity of cell, placed very obliquely, so that the lower is wholly beyond
