Show 1896.] ON MOTHS FROM ADEN AND SOMALILAND. 257 Belenois lordaca feeds at Huswah on Caparis galeata, that if this plant be conspecific with the Aden plant bearing the same name (to the uninitiated the plants look allied, but decidedly distinct from each other). I suspect that T. vi also feeds on this plant, though I have never yet found a larva in spite of careful search. Catopsilia larva? feed on Cassia, sp., but I have been unable to correctly obtain the specific name of this plant; it is, however, allied to adenensis, and may be that species. Zesius livia.-Specimens bred from the pods of Acacia edgeworiliii collected in Gold Mohur Valley. At Haithalhim a number of pupa? were found under a large stone ; from these, too, a species of Zesius emerged. Limnas.-The larva? feed on Calotropis gigantea. Seasonal dimorphism does not seem to occur to any extent in the neighbourhood; though it may possibly do so in the case of Teracolus calais and dynamene. The year 1883 was very wet, heavy rain having fallen in May, consequently in July a large number of Butterflies appeared- among others, a very brightly-coloured form of T. calais (all, I believe, females however): this may point to T. calais being the rainy-season form and T. dynamene the dry. I never met with this unusually brightly-coloured form in after years.-J. W . TERBURY. 2. O n Moths collected at Aden and in Somaliland. By Lord W A L S I N G H A M , M.A., LL.D., F.R.S., and G. F. HAMPSON, B.A., &c. [Eeceived January 29, 1896.] (Plate X.) The following paper contains a record of the collections at Aden and its neighbourhood in the year 1895 by Col. J. W. Terbury and Capt. C. G. Nurse, and of a small Somaliland collection made at Zaila by Capt. Nurse. It also includes the Heterocera recorded from Aden in a paper by Mr. A. G. Butler in the Society's ' Proceedings' for 1884 (collected by Cols. Terbury and Swinhoe), and the few Moths recorded from Somaliland by Mr. Butler in his paper on the Lepidoptera of Somaliland in the Society's ' Proceedings' for 1885, nearly all these species, however, being again represented in the collections now worked out. The Aden forms show, as might be expected, a mingling of the European, N. African, and Western Indian species, the latter decidedly predominating. The number of species is very large for such a barren locality, especially among the Pyralidce, the number of Phycitinae being a marked feature of the fauna, whilst the most interesting new form is the archaic genus of the Nola group.
