SrECiric Character. 



M, alis supra J'uscis ; uuticis fasciis cluabus obsoletis, puncio nigrante tcrminali, 



posticis in medio, tribus macnlisque lutcraldnis abdominis aurantiacis. 



Wings brown; anterior with two darker obscure bands, and a terminal 

 blackish dot; middle of the posterior wings, and three lateral spots 

 on the body, orange. 



1 HIS genus was instituted by Scopoli many years ago, and 

 differs principally from Sesia by having opaque wings, and from 

 Thyreus by the very great difference in the construction of their 

 antenna?. Many exotic species are known, but only one is 

 found in Europe {Sphinx stellatarum of Linn.), which likewise 

 inhabits our own country, and to which this our insect is very 

 nearly allied. 



Though by no means uncommon in collections, I cannot find 

 tliis species either figured or described, nor indeed am acquainted 

 with its locality. The under figure is of the male \ the upper ot 

 the female ; which dillcrs only in the wings being rather broader, 

 and in having one segment in the body less than in the other 

 sex.
