(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 Sphingidee in the collec- 

 tion under their charge. 



1. CHiEROCAMPA MACULATOR, Boisd. Lep. Hct. i. p. 274 

 (1874). 



C. moeschleri, 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 

 baud 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 (18/8), Atlas, 

 pi. 10. fig. 1 (1880). 



The British Museum possesses a male from Buenos Ayres, pre- 

 sented 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 antennae are white behind, and reddish 

 in front. The sides of the thorax above are of a much darker greeu 

 than the centre, and are marked behind with a small white triangu- 

 lar spot ; the first segment of the abdomen is also of a dark green, 

 somewhat yellowish, the remainder being of a yellowish grey. The
