Hah. Hakodadi {Whitehj). Type, B.M. 



Undoubtedly the Japanese representative of 8. radians^ 

 from which, however, it is readily distinguished by its smaller 

 size, paler and duller colouring, the absence of orange colouring 

 on the secondaries, the testaceous scaling on costa and interno- 

 basal area of primaries, the testaceous scales mixed with the 

 brown scales at the sides of the anal tuft, and the cream- 

 coloured femora and tibi^ below.

Hah. Hakodadi, ^ $ [Stephens) ; Japan, ^ {Fortune). B.M. 



Apparently the Japanese representative of S. Juciformts.
