NEW LEPIDOPTERA-HETEROCERA FROM FORMOSA. 



By A. E. WiLEMAN, F.E.S. 



(Continued from p. 32.) 



Dynethia variegata, sp. n. 



Fore wings ochreous, irrorated with purplish brown, and clouded 

 with this tint on the basal half and on the area beyond postmedial 

 line ; antemedial line chocolate-brown inwardly edged with ochreous, 

 angled and thickened on the veins, but extended to the costa ; three 

 chocolate-brown spots on the costa, pale edged, the first triangular 

 with a small spot (discoidal) below, the lower end of the second 

 curved outwards, the third small ; postmedial line ochreous, sinuous, 

 preceded by brown dots on the veins, commencing at the truncate 

 end of the second costal spot ; fringes brown, tips paler. Hind 

 wings fuscous with an indistinct postmedial line, which is angled 

 below the middle. 



Expanse, 29-31 millim. 



Collection number, 877 a. 



Two male specimens from Arizan (7300 ft.), September, 

 1906, and August, 1908. 



Perhaps this may prove to be only a geographical form of D. 

 bicomniata, Warren. 



Dysethia tauvana, sp. n. 



Fore wings dark purplish grey ; three pale edged dark chocolate 

 spots on the costa, the first small and triangular, the second large 

 and curved, the third smaller than the first and somewhat quadrate ; 

 antemedial line dark chocolate, sinuous, not in evidence much above 

 median nervure, slightly expanded on the inner margin ; postmedial 

 line sinuous, dark chocolate towards the inner margin, above which it is 

 angled, indicated by chocolate dots from above vein two to the lower 

 end of second costal spot ; a diffuse, ochreous, transverse shade before 

 the postmedial line. Hind wing fuscous with a faintly darker post- 

 medial line, obtusely angled below the middle. 



Expanse, 34 millim. 



Collection number, 877 h. 



A male specimen from Arizan (7300 ft.), August 18th, 1908. 



Closely allied to D. ocyptaria, Swinboe.
