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

 followed below the third median branch bj a straight oblique 

 line ; an oblique apical dash ; a submarginal series of very- 

 minute brown dots : secondaries whitish, clouded with pale 

 brown ; thorax white, brownish in front, with a central trigo- 

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

 ments whitish ; antennae with tawny pencils ; underside 

 creamy white, the primaries clouded with brown. Expanse,

(J, 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 {WMtely). 



36. Dicranura felina^ n. sp. 



Intermediate in character between D. erminia and D. 

 vinula ; primaries most like those of D. vinula^ but diifering 

 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
