Distribution. N.W. Himalayas ; Sikhim (Hampson) ; 

 Western China. 



Genus SiONA. 

 (Dup. Le> iv. p. 102.) 



Siona naseraria. 



Siona naseraria. Oberth. Etud. d'Entom. xviii. p. 34, pi. v. fig. 72 

 (1893). 



A nice series, composed of specimens taken at Ta-chien-lu 

 and How-kow in June and July. 



Hob. Western China and Thibet. 



I have left this species in Siona, as placed by Oberthiir, 

 but a new genus will probably have to be made for it. 



Genus EUBOLIA. 

 (Dup. ; Hampson, Fauna Brit. Ind., Moths, iii. p. 343 (1895).) 



Eubolia duplicata. 



Oriholiiha duplicata, Warren, Proc. Zool. Soc. Lond. 1893, p. 385. 

 Eubolia duplicata, Hampson, Fauna Brit. Ind. ; Moths, iii. p. 343 (1895). 



Several specimens from How-kow, Thibet, and a few 

 examples from Ta-chien-lu, Pu-tsu-fong, and Kia-ting-fu : 

 June and July. 



The oblique white medial band varies in width; in two 

 specimens it is almost entirely absent, and the black markings 

 are united forming a large triangular blotch. 



Distribution. Chumbi (Hampson) ; Thibet j Western 

 China. 



Eubolia similaria, sp. n. 



Allied to E. peribolata, Hiibn., from Europe, but larger ; 

 the outer edge of the central band of primaries is bilobed, 

 and between the inner edge of the band and the base of the 

 wing there are several transverse lines. Secondaries whitish, 

 tinged with fuscous along the basal portion of the abdominal 

 margin ; there are indications of a discal spot and central 

 line, tinder surface similar to that of E. peribolata. 



Expanse 38 millim. 



Several specimens of each sex from Ta-chien-lu, Wa-shan, 

 and Ni-tou : May and June. 



Hob. Western China. 



Peribolata, Htibn., is included in Xanthorhoe, Hiibn., by 

 Meyrick (Trans, Ent. Soc. 1892, p. 77).
