190 MESSES. H. J. ELWES AM) JAMES EDWAEDS : 



! Aeromachus inachus. (Plate XIX. fig. 7 ; Plate XXIII. figs. 86, 36 a.) 



Pyrgus inachus, Menetries, Bull. Acad. Petr. xvii. p. 217 (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.

<S . Upperside dark olive-brown, the postmedian series of spots on the fore wing 

 very indistinct or wanting ; sex-mark on the fore wing a small inconspicuous fold 

 of raised scales in cell 1 a next vein 1 a near the middle. Underside : fore wing 

 umber-brown, the apical and costal regions similar to the hind wing'; a small pale 

 spot near the upper distal angle of the cell; the postmedian series of pale spots 

 represented by about six spots, which become gradually fainter in their course from 

 cells 8-3 ; a pale anteciliary line : hind wing ochreous brown by reason of a close 

 sprinkling of yellow scales on the umber-brown ground ; the postmedian and sub- 

 terminal series of pale spots very indistinct or wanting ; a pale anteciliary line. 

 Fringes greyish white, the short scales grey-brown. Antennae above blackish, 

 minutely spotted with yellowish : beneath greyish yellow, the shaft spotted with 

 black. Second joint of palpi clothed with yellow and black hairs intermixed. 

 Body above concolorous with the wings, beneath with greyish-yellow pubescence. 

 Legs with greyish-yellow scaling. 



Tegumeu (seen from above) with a small rounded projection near the apex on 

 each side, beyond which it is produced in a bluntly rounded triangle.
