cf ? . Fabricius and Gmeliu overlooked this species. Hiibner was the first to 

 include it again in the list of Sphingids. It comes close to fadus in ccdonr, but 

 cannot very well be confounded if one pays attention to the I'ollowing points: 

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

 of hindwing more extended and denser ; foreleg of c? with two consjiicuons i)lack 

 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. ArgeM., l.c., but he considered it to 

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