80 MR. A. G. BUTLER ON APORIA HIPPIA. (Jan. 19,

Q. capite et collo mari similibus, nee gula rufescente: dorso 
brunneo, plumis albo et castaneo arcte marginatis: alis sicut 
in mare coloratis: secundariis viridescentibus albo terminatis : 
cetera ut in mare. 
If this bird be correctly discriminated, it adds a fourth to the three 
recognized species of Dajila, the others being D. acuta, extending over 
the whole northern hemisphere; D. spinicauda, and D. bahamensis, 
both neotropical species. 
4. Note on Aporia hippia. By A. G. Burtzr., F.L.S., 
F.Z.8., &e. 
[Received January 18, 1886.] 
The British Museum has received specimens of the imago, larva, 
and pupa of Aporia hippia, reared in the Society’s Gardens under 
the care of Mr. A. Thomson during the past season (see his report, 
above, p. 3). I beg leave to offer a few remarks on them. 
APORIA HIPPIA. 
Pieris hippia, Bremer, Bull. de Acad. St. Pétersb. ili. p. 464 
(1861); Lep. Ost-Sibiriens, p. 7, nu. 12, pl. 3. fig. 1 (1864). 
Leuconeéa crategioides, Lucas, Ann. Soc. Ent. France, 4° sér. 
t. 5, p. 503, pl. 11. fig. 11 (1865). 
Although, as appears from the above, this species has been twice 
figured, neither figure can be called a characteristic one; both are 
too pale and fail to show the grey expansion at the extremity of the 
nervures ; nothing is said of the earlier stages in either Bremer’s or 
Lucas’s descriptions, indeed the latter author evidently imagined it to 
be a “ pretty variety” of A. crategi, although he described it as if 
a distinct species ; he did not, however, call it “‘ Leuconea crategi, 
var. crategoides” (sic) as quoted by Kirby. 
Staudinger failed to quote the original description; but this sort 
of omission is of frequent occurrence in his Catalogue, and leads to 
errors innumerable; thus, in the case of Chrysophanus dido of 
Gerhardt’s ‘Monograph of Lyceenide,’ Staudinger (who appears 
entirely to have overlooked the work) quoted Herrich-Schaffer’s 
figure of the male “ asabinus, H. 8S. 527.8” only, and subsequently 
Kirby, in his Catalogue, referred the figure of the female to C. chry- 
seis, and regarded it as a variety of the C. hippothoe of Linneus. 
To return, however, to 4. Azppia, it is undoubtedly nearly allied 
to A. crategi, but is as certainly distinct ; the blackish veins and 
yellow under-surface of the secondaries and apex of primaries readily 
serve to distinguish it. 
Among the specimens in the Museum, all of them reared and 
presented by the Society, is a female which shows an interesting 
aberration of vein-structure, the radial vein of the right-hand hind
