Note on the Genus Brahmcea of Walker. By A R T H U R G. BUTLER, F.Z.S. In laying before the Society the result of my investigations with regard to these figures, which were prepared for Mr. Adam White, formerly Assistant in the Zoological Department of the British Museum, and intended to illustrate a paper in the Society's ' Proceedings,' I wish it to be thoroughly understood that I have seen none of the specimens from which they were taken, and that I am therefore compelled to depend upon the drawings alone for the descriptions of the species. There are two examples of the old species B. certhia in the National Collection. Genus BRAHMCEA, Walker. Section 1. 1. BRAHMcEA CERTHIA. (Fig. 1.) Bombyx certhia, Fabricius, Ent. Syst. iii.
