180 Mr. J. H. Leech on 



Thisanoptyx brevimacula, Alph., Rom. sur Up., ix, p. 1S6, 

 pi. xi'ii, fig. 5 $ (1897). 



Occurs at Moupin, Omei-shan, Chia-kou-ho and Chang- 

 yang, in June. Brevimacula, Alph., described from a female 

 specimen taken at Ta-choui-van, is a form of T. siffnata. 

 Walk., in which, judging from the figure, the abdominal 

 area of the secondaries is paler than the outer area. Two 

 of my specimens from Chang-yang have the lower spot on 

 primaries elongated, and in one example from Moupin the 

 upper or costal spot is absent from left primary, and very 

 small on the right primary. 



Distribution. Eastern, Western and Central China. 



573. Thysanoptyx directa, sp. n. 



Primaries greyish stramineous, with a black spot on the costa- 

 beyond the middle, and an upright, elongated mark of the same 

 colour on the inner margin. Secondaries rather yellower. Under 

 surface yellower than above, the discal area of primaries suffused 

 with blackish. Head stramineous ; thorax and abdomen colour of 

 primaries, but the terminal segments of the latter are yellowish and 

 the thorax is marked with blackish. 



Expanse 38 millim. 



Two female specimens from Chang-yang, taken in June, 



Habitat. Central China. 



Allied to T. sigiiata. Walk., but the mark on the inner 

 margin of primaries is narrower, and is placed more directly 

 under the costal spot.
