Alpheraky (liom. sur Lcp. v. p. 121) records a single female taken in June 

 at Yan-myn-gouan, in the province of Chan-si, North China, Avhich he says 

 differs from typical specimens in the yellower green coloration of the under 

 surface of secondaries. This author makes no reference to //, gi(jas, Bremer, 

 which has not hitherto been recorded from the region here dealt with, 

 although it occurs in Central Asia as Avell as Amurland. 



Dr. Staudinger, who formerly considered this species might be a form of 

 H. [P.) gigas, Bremer, but has since altered his opiuion, states that Graeser 

 informed him that there were specimens of //. tesseUum 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 band, 

 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.

 obscure line above the spiracles. Head brown. Feeds on Lotus corniculatus in May and 

 September.

According to Staudinger this must be a very rare insect in Amurland, as 

 it has not been recorded from that region since Radde met with it. He also 

 states that Herz found the species in North China, and the specimens differed
