544 MR. A. G. BUTLER ON THE SPHINGID#. 
The figure of this species seems hardly to agree with Hemeroplanes, the antenne 
being represented as thicker than in /. triptolemus, and withont the terminal curvature 
common to that species and represented by Cramer in his species of this genus; in 
the form of the primaries also it seems almost to approach Philampelus.

I am inclined to think that this is an exaggerated Calliomina.

1 This genus has the aspect of the genus Yriptogon (Smerinthine) ; but the structure of the larva proves it to 
belong to the Cheerocampinz.
