Basychira argentata, Butl. Trans. Ent. Soc. 1881, p. 12. 



Calliteara pseudahietis, Butl. Cist. Ent. iii. p. 118. 



Though certainly somewhat darker in colour, argentata is in no 

 other respect separable from G. abietis, Schiff. I am therefore 

 disposed to consider it as well as pseudahietis forms of that species.

Artaxia confusa, JBrem. Lep. Ost-Sib. p. 42, t. iv. fig. 5 (1864). 



A fine series from Japan varying much in colour and intensity of 

 markings ; some of the examples agree exactly with Amur specimens.

Porthetria lucescens, Butl. Trans. Ent. Soc. 1881, p. II. 



Two specimens in Fryer's collection labelled no. 177, Oiwake, 

 July and August 1877 ; but in his Catalogue the locality given for 

 the species is Ohoyama.

Var. jAPONiCA. 



Two specimens, coll. Pryer, Hakodate. In Japanese examples of 

 A. tau the submarginal line of all the wings is further from the mar- 

 gin, and less strongly defined on the primaries than in European 

 specimens ; the black spot of primaries is also rather smaller, and in 

 the male there is a whitish patch at apices as in female ; also the 

 ocellus on secondaries is larger than in European specimens, whilst 

 that on primaries is much smaller. The female is darker than 

 typical specimens of same sex, with the costa, outer third of 

 primaries and costa, and abdominal fold of secondaries thickly 

 sprinkled with black dots and powdered with black scales. 



Expanse, d 80, $ 108 millim. 



These differences are, however, too insignificant to be considered 

 of specific value, so I venture to propose that it be known as /iglia 

 tau, var. japonica.
