 tarsi chocolate-brown ; basal half of venter clothed with red- 

 brown and whitish hair-scales, anal half with yellowish creamy

Bab. Hakodadi (Whitehj). Type, B.M. 



Undoubtedly the Japanese representative of S. 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 tibia? below. 



Sesia Whitelyi, n. sp. 



$ . Wings above hyaline, with lilacine reflections, veins- 

 black ; primaries with costa and interno-basal area black,

 external angle), undulated between the nervures internally; 

 fringe brown, with a pale internal line ; secondaries with 

 costa, base, and inner margin grey ; outer margin dark choco- 

 late-brown (1 millimetre wide), an interno-median decreasing

 coloured, of secondaries dark brown ; interno-median streak

Hab. Hakodadi, $ $ (Stejrfiens) ; Japan, $ [Fortune). B.M. 



Apparently the Japanese representative of S. fuciformis. 



* There appears to be a blackish dorsal streak ; but it may be due to 

 rubbing.
