190 MESSES. H. J. BLWES AND JAMES EDWARDS: 



! Aeeomachus inachus. (Plate XIX. fig. 7 ; Plate XXIII. figs. 36, 36 a.) 

 Pyrgus inachus, Menetries, Bull. Acad. Petr. xvii. p. 317 (1859) ; Schrenk's Reisen, p. 46, pi. iv. 

 fig. 2 (1859). 



Closely allied to stigmata, but separable by its somewhat paler colour and the 

 different form of the sex-mark. 



It has the wing-shape of chinensis. 



We have not been able to identify this with Menetries's type except by the locality ; 

 but Amur specimens agree well with those from Japan. Mr. Leech has included under 

 this name what we call chinensis, and we have specimens from his collection which 

 were mixed with others from Western China but which may be from Japan.
