136 Noctuid moths from Japan. 



reddish dentate-sinuate stripes, which, however, frequently are 

 wholly lost in the ground colour ; two reversed dentate-sinuate 

 darker lines or two stripes sKghtly paler than the ground colour 

 indicate the limits of the central belt ; the orbicular spot is usually 

 ill-defined or absent, but sometimes represented by a whitish spot ; 

 the reniform spot is oblique, large, usually whitish, but sometimes 

 ochreous, though always with a white or whitish external edging ; 

 the outer line or stripe bounding the central area occasionally has 

 its dentate character defined by a series of black points at the 

 extremities of the denticles ; so far all the characters are variable 

 and inconspicuous ; the following characters are always better 

 marked — a dark brown almost semicircular basi-costal patch, an 

 unequally quadrate costal patch of the same colour beyond the cell, 

 an irregular more or less dusky outer border bounded internally by 

 a paler stripe, two more or less defined hastate black dashes on the 

 radial interspaces interrupted by the submarginal j)ale stripe ; a 

 marginal series of black crescentic dots with pale inner edges and 

 several dusky or blackish costal dashes ; secondaries varying from 

 grey to brown, always sericeous, and with pale golden or bright 

 cupreous reflections, a more or less distinct darker diffused external 

 border ; an ill-defined marginal series of blackish dots ; fringe 

 whitish ; body whity-brown ; head, collar and tegulae dark brown, 

 varying in accordance with the colour of the primaries from greyish 

 to reddish ; under siu*face varying from whitish to bronze-brown ; 

 primaries with the central area slightly greyish ; all the wings 

 with a blackish disco-cellular spot and two parallel discal lines fi-om 

 costal to inner margins. Expanse of wings, 34 — 50 mm. 



Male and female, Tokei (C. Maries) ; female, Chekiang 

 (IF. B. Pryer) ; male and female, Yokohama (//. Fryer), 



This perfectly typical Polydesma is noted by Mr. H. 

 Pryer as a Xylophasia. It is an unusually variable 

 species.
