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. excecatus, 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. 
Genus 11. CaLasyMpouus, Grote. 
Calasymbolus, Grote, Bull. Buff. Soc. Nat. Sci. p. 23 (1873). 
Differs from Smerinthus in the form of the primaries, and from Paonias in the form 
of the secondaries.

“ Atlantic District!” (Grote and Robinson). 
Strecker’s figure of this species has the two opposite primaries rather different m 
outline; but, judging from Drury’s figure, I have little doubt as to its genus.
