-/Egeriidae 
Genus SYNANTHEDON Hubner 
(Sesia auctorum.) 
The name Sesia being'properly restricted to a genus of the 
Sphingidce, we apply to the genus the name proposed by Hubner 
in ihe “ 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. 
(1) Synanthedon rileyana Henry Edwards, Plate XLVI, 
Fig. 22, $, Fig. 23, $. 
Syn. brunneipennis Henry Edwards ; hyperici Henry Edwards. 
The species ranges from the Virginias and Carolinas west¬ 
ward through Ohio and Illinois as far as California and Oregon.

only infests the crown of these plants, which it generally destroys, 
but also frequently attacks raspberries and blackberries at the 
crown of the roots. It ranges from Nova Scotia westward across 
the continent, and in the Mississippi Valley southward into north¬ 
ern Texas.
