Nsnia muscosa. (Plate XLVI. fig. 9.) 
Xaeiiia muscosa, Butler, Ann. 4’ Marj. Nat. Hist. ser. 5, vol. i. p. 290 (1878). 
Primaries sericeous greyish brown, with darker and paler markings much as in N. typica, 
hut with the orbicular and reniform sj^ots, a basal spot, a subbasal interno-median spot, and 
a spot near external angle pale greenish ; inner geminate line much more undulated, sub- 
marginal black-edged whitish line strongly dentated, the centre forming two ^-shaped 
characters: secondaries sericeous grey, w'ith darker central line and outer border; fringe 
as in N. typica : thorax pale testaceous, the collar sordid whitish at the base on each 
side, and surrounded by semicircular blackish lines ; abdomen greyish. Wings below pale 
sericeous whity brown, the disk greyish ; two dark grey discal lines ; marg-inal black liturse ;

HYPOGRAMMIDiE. 
GERBATHA, Walker. 
Gerbatha ypsilon. (Plate XLVII. fig. 1.) 
Grey: primai’ies with a lilacine tint and speckled with black; an irregularly sinuated 
black line across the basal area ; a broad shining bronze-brown Y-shaped band across the 
wing beyond the middle, its external branch and main stem traversed by a sinuated central 
black line ; a dentate-sinuate submarginal dusky line with a white external border ; a mar- 
ginal series of white-edged conical black spots ; three or four white costal dots towards apex ; 
a white v-shapcd marking at the inferior extremity of the cell : secondaries bronzy brownish, 
slightly darker at outer border ; fringe whitish, with a central dusky line ; body corresponding 
in colour with the wings. Under surface sericeous, the markings for the most part obsolete; 
secondai’ies with well-marked discocellular spot and angulated discal line. Expanse of wings 
1 inch 4 lines. 
Yokohama [Jonas). 
Gerbatha angusta. (Plate XLVII. fig. 2.) 
Allied to the preceding species, but the primaries darker and narrower ; forked bronzy 
band wanting ; the black lines, although similar in direction, differ in sinuation : the discoidal 
markings generally outlined clearly in white ; a white spot below the orbicular spot ; other- 
wise very similar. Expanse of wings 1 inch 5 lines. 
Y^okohama [Jonas] . 
Evidently much commoner than G. ypsilon.
