1886. ] MR. W. F. KIRBY ON RARE SPHINGIDZ. 269 
1. Remarks on four rare Species of Moths of the Family 
Sphingide. By W.F. Kirgsy, Assistant in Zoological 
Department, British Museum (S. Kensington).

(Plate XXVIT.) 
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 Sphingide in the collec- 
tion under their charge.

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 Moéschler. 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.

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 antenne 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 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
