Alpheraky (Rom. sur Lep. v. p. 121) records a single female taken in June 
at Yan-myn-gouan, in the province of Chan-si, North China, which he says 
differs from typical specimens in the yellower green coloration of the under 
surface of secondaries. This author makes no reference to //. gi(/as, Bremer, 
which has not hitherto been recorded from the region here dealt with, 
although it occurs in Central Asia as well as Amurland. 
Dr. Staudinger, who formerly considered this species might be a form of 
//. (P.) giffas, Bremer, but has since altered his opinion, states that Graeser 
informed him that there were specimens of ff. tessellum from Amurland in 
Tancre's collection, but Dr. Staudinger seems inclined to doubt the accuracy 
of this statement.

"Expands from 1 to 1'25 in. Fore wings with the discal portion grey; near the costa is a large 
dark brown spot and another near the inner margin ; there is a submarginal dark brown baud, 
and a marginal band of a still darker colour, having whitish dots. This pattern is most 
marked in the male; in the female it is less distinct and paler. Hind wings dark brown, 
with a darker marginal band, on which are dots similar to those on the fore wings, and often 
some pale spots on the discal portion. Underside almost uniform brown, lighter than above. 
Fringes of all the wings brown and without spots. April and August.

According to Staudinger this must be a very rare insect in Amurland, as 
it has not been recorded from that region since Eadde met with it. He also 
states that Herz found the species in North China, and the ispecimeus differed
