 Genus SYNANTHEDON Hubner 



(Sesia auctorum.) 



The name Sesi'a being properly restricted to a genus of the 

 SphiugidiV, we apply to the genus the name proposed by Hubner 

 in the " Verzeichniss Bekannter Schmetterlinge," p. 129. This 

 appears to be the proper and logical method of procedure under 

 the circumstances. 



The genus is very extensive. Fifty-eight species are found in 

 our fauna, of which we delineate eleven.

 Fig. 22, 6 , Fig. 2}, ? . 



Syn. brunncipetniis Henry Edwards ; hyperici Henry Edwards.

 ern Texas.
