544 MR. A. (i. BUTLER ON THE SPHTNGID.E. 



The figure of this species seems hardly to agree with Jlemeroplanes, the antenna? 

 being represented as thicker than in 77. triptolemus, and without 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.

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

 lielong to the Chcerocampinte.
