600 MR. A. G. BUTLER ON THE SPHINGID.E. 



This species is certainly distinct ; Cramer's figures of A. medor and A. hydaspus are 

 evidently both taken from female examples ; the white spots are most distinctive.

Comparing this species with the various allied but distinct forms in the genus Bilo- 

 phonota, several of them sent by the same collector from Oaxaca, Mexico, I cannot 

 believe that Drury's figure can be so gross as to be a representation of the Sphinx alope 

 of Cramer ; not only is the banding and coloration of the primaries utterly different, but 

 the body is both described and represented as "clay-coloured;" I therefore adopt Swain- 

 son's name of Sphinx fasciata for Cramer's insect.

1 Allied to Amphonyx ; thorax with a broad and very prominent dorsal tuft, dilated in front and excavated 

 above ; proboscis long, but shorter than in Amplionyx ; head and thorax projecting a long •way in front of pri- 

 maries ; secondaries narrow, especially towards apex.
