externally and speckled with smoky brown : body pale brown ; palpi, antennse, and front legs 
darker. "Wings below whitish, reticulated with greyish lines, which are most distinct upon the

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 area : secondaries slightly paler than the primaries. 
Wings below^ less distinctly reticulated than above, especially the primaries, which are 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 : 
l)ody greyish. Expanse of wings 1 inch 6 lines. 
Yokohama {Jonas) ; Hakodate {TVhitely). 
Closely allied to H. jn'oboscidalis. 
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 wdiite, 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 
paler and greyer. Expanse of wings 1 inch 5 lines. 
Hakodate {IVhitely). 
Hypena squalida. (Plate LVI. fig. 2.) 
Greyish brown ; primaries reddish brown tow'ards the base, and with a large wdiitish- 
Irordered black -edged reddish-brown patch, nearly resembling the dark area of the preceding

This species also belongs to the H. crassalis group, but is most nearly allied to H. bijugalis 
of Nova Scotia.
