near the costa) crossing the wing just beyond the middle, and 

 followed below the third median branch by a straight oblique

 nate, scutiform, testaceous patch ; body testaceous, anal seg-

 creamy white, the primaries clouded with brown. Expanse,

(5", Yokohama {Jonas) ; $ , Japan [Pryer). 



The markings on the primaries of the male are indistinct. 

 The genus Bireta is closely allied to Ceira. 



35. Cerura lanigera^ n. sp. 



Nearly allied to C.furcula^ but the discal area of primaries 

 clouded with grey, the central band blackish, constricted in 

 the middle, its inner edge being angulated ; the ochreous 

 scales replaced by a few scattered stramineous scales ; the 

 outer discal lunate line replaced by well-defined blackish 

 lunate spots ; external area (excepting the outer margin) 

 greyish in all the wings: body whiter, with blacker abdominal 

 bands. Underside of wings considerably darker. Expanse 

 2 inches. 



Hakodate {Whitely). 



36. Dicranura felina^ n. sp. 



Intermediate in character between D. erminia and D. 

 vinula] primaries most like those of D. vinula, but differing 

 from both species in that the outermost discal line is much 

 more deeply waved, and from D. erminia in the deeper 

 waving of both discal lines ; the innermost (or third discal) 

 line of D. vinula does not extend in this species beyond the 

 first median branch : secondaries white as in D. erminia, but 

 with a well-defined, blackish, discocellular lunule : body 

 almost as in D. vinula. Expanse, ,^ 2 inches 5 lines, ? 2 

 inches 8 lines. 



Yokohama {Jonas). 



37. Peridia gigantea, n. sp. 



Nearest to P. trepida, but with a broader internal projecting 

 scale-patch than in any other species ; above greyish brown : 

 primaries with a broad, subquadrate, subcentral, whitish patch 

 from the costa to the median vein, where it becomes more 

 distinctly testaceous, and is continued as an ill-defined streak 

 below the first branch for half its length and terminates in a
