500. Spilosoma hifasciata. 



Sp)ilarctia hifasciata, Butl., Trans. Ent. Soc. Lond.,

Butler's type was from Tokio. There were three speci- 

 mens from Nikko in Fryer's collection, and I received one 

 from Mr. Manley of Yokohama. 



In one of the Nikko examples the medial portion of 

 the sub-basal band on primaries is absent, and the central 

 band is interrupted. 



Habitat. Japan. 



Kirby (Cat. Lep. Het., i, p. 232) mentions iS*. hifasciata, 

 Hampson, and gives the locality as " China," but Hampson 

 (Fauna Brit. Ind., Moths, ii, 9) refers to the species as 

 from the " Nilgiris." I have not seen anything from 

 China to agree with Hampson's description of S. 

 hifasciata.
