Smerinthus heynet, Austaut, Le Nat., 1892, p. 68. 
A fine series from Yokohama in Pryer’s collection. I 
met with the species at Nagasaki in May and have received 
it from Hakodate and also from Moupin; the specimens 
from the latter place were taken in June. 
The larva is stated by Staudinger to feed on Pyrus 
and Crategus, whilst Dorries says that it feeds on cherry 
and plum and is similar in appearance to the larva of 
Smerinthus ocellatus. 
Austaut’s description of heynei evidently applies to 
Japanese representatives of this species. He refers to 
gaschkewitschii and var. carstanjeni as though he considered 
them distinct species, whilst he does not mention either 
roseupennis or complacens.

There were specimens from Oiwake and Tokio in Pryer’s 
collection which agree with examples from Amurland. In 
one individual from Kiukiang the body and ground colour 
of the wings are rosy-brown instead of olive-brown.
