I obtained the species in various parts of Japan, where 
it is very plentiful; I also took a specimen at Gensan. In 
a series received from Ichang all the specimens were 
below the average size, and some of the examples measure 
only 70-73 millim. in expanse. The characters given by 
Hampson as distinguishing styx from atropos appear to be 
of little specific value. The bands on the under surface 
of the abdomen are sometimes almost absent in European 
specimens and in the Asiatic form are usually represented 
by rows of spots. Then with regard to the two medial 
bands on the under surface of the forewings, these may be 
present or absent in specimens from either region. 
Medusa, Butl., from Japan has no constant character to 
separate it from the Indian form.
