I'he proboscis is short, and the antennae are shortly 

 pectinated in the male. The wings are broader than in the 

 allied genera, and are regularly dentated. In addition to our 

 Poplar Hawk-moth, three other species, all, I belicYC, poplar- 

 feeders, are found in the Western Pal?earctic Region. One 

 of these, A. ireniuloi (Fischer), is smaller than A. popidi^ and 

 has no red patch at the base of the hind-wings. It is a 

 scarce Russian species. 



The other two species are much larger and paler than 

 A. popiili (expanding four inches and upwards) ; one, A. 

 popideti (Bienert), is found in North Persia ; and the other, 

 A. ausimiti (Staudinger), which is a very variable insect, but 

 usually of a pale grey colour, is found in Algeria.
