Cossus cossus, Fixsen, Rom. sur Lép., iii, p. 337 (1887). 
Fixsen records this species from Corea. Staudinger 
(Rom. sur Lép., vi, p. 291) refers to a specimen which he 
received from Hertz, who took it in the north of Pekin, as 
Cossus cossus ; from his description of this example, how- 
ever, it would seem to be C. vicarius.

Cossus vicarius, Walk., Cat. Lep. Het., xxxii, p. 584 (1865). 
Trypanus vicarius, Kirby, Cat. Lep. Het., i, p. 861 (1892). 
There were two specimens in Pryer’s collection but 
without data. I took a male at Gensan and I have 
received one taken by a native collector at Nikko. My 
collectors in China appear to have met with the species 
at Ta-chien-lu only where one female example was 
obtained.
