Cahjmnia frijeri, Leech, Proc. Zool. Soc. Lond., 1889, 

 p. 516, pi. li, fig. 11. 



I have three specimens from Oiwake, two of which are 

 females. 



This species somewhat resembles Mcsogona oxalina 

 from Europe ; it varies in tint of primaries, and the 

 secondaries in two examples are more suffused with fuscous 

 than in the type. Perhaps it may eventually prove 

 to be a form of " Grammcsia" hifasciata. Stand., from 

 Amurland, but the latter is darker in colour, and the post- 

 medial line of primaries is more distinctly curved. 



Habitat. Japan.
