Show 1884.] LEPIDOPTERA FROM ADEN. 485 17. DEUDORYX LIVIA. Lycana livia, Klug, Symb. Phys. pi. 40. figs. 3-6 (1834). Aden, 25th December, 1883 ; 5th, 6th, and 20th January, and 17th February, 1884. The female of this species (of which Klug figures two males) closely resembles the Dipsas antalus of Hopffer, two females of which are evidently represented as sexes. PAPILIONID^E. 18. T E R I A S CHALCOMI^ETA. Terias chalcomiata, Butler, Ann. & Mag. Nat. Hist. ser. 5 vol. iii. p. 190, n. 10 (1879). Lahej, 3rd and 6th April; Haithalkim, 4th April, 1884. The seven examples forwarded by Major Yerbury are separated by him under four different numbers, probably on account of their difference of size and the more or less pronounced character of the markings on the under surface; in some specimens these are as sharply defined as in T. cesiope, whilst others agree with the type from Johanna in almost every particular. The Catopsilia of the collection appear to repeat, to a certain extent, the peculiarities of the forms of Limnas, since they are undoubtedly connected by intergrades in such a manner as to render their separation very difficult. When I published my Monograph of Callidryades, I recognized two African types, Catopsilia pyrene and C. florella, which, at the time, were believed by Mr. Trimen to be dimorphic forms of one species ; this belief was based upon the capture of a supposed C. pyrene 8 in coitu with a 0. florella $: his words are as follows:-" On one occasion near Durban, Port Natal, I took a white 8 and yellow $ in copuld. Females of the paler colouring are certainly scarcer than the others; but Mr. Bowker writes that he has noticed them in Basuto-Land, and Mr. Hewitson possesses one from Madagascar, which resembles the yellowish-white specimen from Bourbon, figured in M . Maillard's * Notes sur l'lle de la Reunion (Bourbon),' published in 1862." The pale female in Mr. Hewitson's collection is m y G. rufo-sparsa, and differs from C. florella not only in its pale colouring, but in the total absence of the angular subapical series of spots on the primaries, the shorter secondaries, the ochreous instead of chrome-yellow colouring of the under surface, the denser and less striate character of the reticulate markings, and the suffused ill-defined character of the discal series of spots. In a collection received some years since from Abyssinia were great numbers of a Catopsilia which I took to be C. florella, and one of these I selected for the sake of its locality. On setting it, however, I found it so distinct-the central area of the wings being occupied by a broad white belt, and the under surface of the secondaries showing only one instead of three silver spots-that I concluded to describe it as a new species under the name of C. aleurona. |
