c? ? . Pabricius and Gmelin overlooked this species. Hiibner was the first to 

 include it again in the list of Sphingids. It comes close to Jad us in colour, but 

 cannot very well be confounded if one jiays attention to the following points : 

 discal spots of forewing always simple, never divided, white scaling at anal angle 

 of liindwing more extended and denser ; foreleg of c? with two conspicuous black 

 tults, one at the end of the femur, the other near the apex of the tibia. The tibial 

 tuft is mentioned by Burmeister in Descr. Rip. Argent., I.e., but he considered it to 

 be a character of the whole genus, while it is present only in titan.
