Show 1886.] MR. W. F. KIRBY ON RARE SPHINGID^. 269 1. Remarks on four rare Species of Moths of the Family Sphingida?. By W. F. KIRBY, Assistant in Zoological Department, British Museum (S. Kensington). [Received April 16, 1886.] (Plate XXVII.) I am indebted to Prof. V. Ball and Mr. Nichols, of the Dublin Museum of Science and Art, in which most of the species noticed in this paper are contained, for an opportunity of carefully examining and figuring some of the more interesting Sphingidce in the collection under their charge. 1. CILEROCAMPA MACULATOR, Boisd. Lep. Het. i. p. 274 (1874). C. mceschleri, Ersch. Trudy Russk. Ent. x. p. 64, t. i. f 1 (1876). The identity of these supposed species has been suggested from the first. There is a specimen in the Dublin Museum which agrees with Erschoff's figure, except that it is not quite so dark, and the pale band of the hind wings is rather broader and has a slight pinkish tinge. This specimen was, I believe, received from Herr Moschler, labelled " C. maculator, Boisd., Colombia." Boisduval's type was from "Venezuela," and Erschoff's from "Colombia," the latter having been also received from Moschler. Boisduval's description agrees well with the Dublin specimen, except that he calls the pale band of the hind wings " jaune terreux," and seems to imply that the dark blotch on the fore wings is nearer the centre than is actually the case. But I am not disposed to attach too much importance to these trifling discrepancies. 2. AMBULYX EOS, Burm. (Plate XXVII. fig. I.) Philampelus eos, Burm. Desc. Rep. Arg. v. p. 350 (1878), Atlas, pi. 10. fig. 1 (1880). The British Museum possesses a male from Buenos Ayres, presented by Walter de Rothschild, Esq., which differs so much from Burmeister's figure of the female that I have thought it worth while to figure it. The vertex, thorax, and fore wings are of a dull green, slightly inclining to olive above; the face and under surface of the thorax are greenish yellow, the base of the labrum and the knees being narrowly white. The antennas are white behind, and reddish in front. The sides of the thorax above are of a much darker green than the centre, and are marked behind with a small white triangular spot ; the first segment of the abdomen is also of a dark green, somewhat yellowish, the remainder being of a yellowish grey.
