I believe Drury's locality to be incorrect; his name is therefore not appropriate. 

 Although the primaries of this species agree with Calasymbolus in the absence of the 

 undulation of outer margin, it agrees so closely in all other structural respects with 

 P. exccecatus, that I am satisfied to leave it in the same genus with it. The form of 

 the secondaries in Paonias is markedly distinct from Calasymbolus, the apical part of 

 costa being abruptly convex, modifying the first branch of the subcostal nervure.

Differs from Smerinthus in the form of the primaries, and from Paonias in the form 

 of the secondaries.

Strecker's figure of this species has the two opposite primaries rather different in 

 outline; but, judging from Drury's figure, I have little doubt as to its genus.
