Long. tot. in. 20*5, rostri, 2, alee 106, caudce 4, tarsi 1*4. 2. capite et collo mari similibus, nee gula rufescente: dorso brunneo, plumis albo et castaneo arete marginatis : alis sicut in mare coloratis : secundariis viridescentibus albo terminatis ccetera ut in mare. If this bird be correctly discriminated, it adds a fourth to the three recognized species of Dafila, 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. B U T L E R . , F.L.S., F.Z.S., &c. [Eeceived 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 l'Acad. St. Pe'tersb. iii. p. 464 (1861) ; Lep. Ost-Sibiriens, p. 7, ii. 12, pi. 3. fig. 1 (1864). Leuconova cratcegioides, Lucas, Ann. Soc. Ent. France, 4me ser. t. 5, p. 503, pi. 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. cratcegi, although he described it as if a distinct species ; he did not, however, call it " Leuconaa cratcegi, var. cratagoides" (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 Lycaenidae,' Staudinger (who appears entirely to have overlooked the work) quoted Herrich-Schaffer's figure of the male " asabinus, II. S. 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 Linnaeus. To return, however, to A. hippia, it is undoubtedly nearly allied to A. cratcegi, 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 |
