60 HYPENID.^. 



black spot ; external area reddish brown : secondaries sordid white, slightly brownish 

 externally and speckled with smoky brown : body pale brown ; palpi, antenna, and front legs 

 darker. Wings below whitish, reticulated with greyish lines, which are most distinct upon the

 the cell and by two black spots near the apex. Expanse of wings 1 inch 3 lines. 

 Yokohama [Jonas). 



Hypena tatorhina. (Plate LV. fig. 13.) 



Pale greyish brown, more or less distinctly reticulated with darker striations of the same 

 colour : primaries crossed by two slightly sinuated parallel oblique darker lines ; a third very 

 ill-defined line limiting the external ai-ea : secondaries slightly paler than the primaries. 

 "Wings below less distinctly reticulated than above, especially the pi-imaries, which ai'e marked 

 near apex with two or three white dots parallel to the outer margin ; discocellulars dusky ; 

 an abbreviated dusky transverse streak beyond the cell : secondaries with a dusky discocellular 

 spot ; an indistinct postmedian angular dusky line; apical area broadly dusky, but not defined : 

 body greyish. Expanse of wings 1 inch 6 lines. 



Yokohama (Jonas) ; Hakodate [IVhitely). 



Closely allied to H. prohoscidalis. 



Hypena zilla. (Plate LVI. fig. 1.) 



Nearly allied to H. crassalis of Europe, but rather larger and less brilliant in colour, 

 the broad irregular dark area of primaries scarcely extending beyond the middle of the wing, 

 its outer edge bracket-shaped and clearly bordered with white, its inner or inferior edge more 

 deeply excised towards the base ; markings on the disk less strongly defined, the apical streak 

 broken up into small elliptical spots ; external border scarcely touched with grey : secondaries 

 jjaler and greyer. Expanse of wings 1 inch 5 lines. 



Hakodate [Uliitely). 



Hypena squalida. (Plate LVI. fig. 2.) 



Greyish brown : primaries reddish brown towards the base, and with a large whitish- 

 bordered black-edged reddish-brown patch, nearly resembling the dark area of the preceding 

 species ; an irregular discal series of blackish spots near the outer margin, their outer edges 

 bordered with white ; a marginal series of black spots at the tenninations of the veins : 

 secondaries with a mai-ginal series of black sjjots and a whitish fringe. Under surface whity 

 brown, secondaries with veiy indistinct discal brownish line and discocellular spot. Expanse 

 of wings 1 inch 2 lines. 



Yokohama [Jonas) . 



This species also belongs to the H. crassalis group, but is most nearly allied to H. bijugaUs 

 of Nova Scotia.
