544 MR. A. G. BUTLER ON THE SPHINGID^. 



The figure of this species seems hardly to agree with Ilemeroplanes, the antennae 

 being represented as thicker than in H. 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 Calliomma .

1 This genus has the aspect of the genus Triptogon (Smennthince) ; but the structure of the larva proves it to 

 belong to the ChaerooampinEe.
