primaries ; from G. mactans it differs in its narrower 
central belt, which is sericeous golden yellow varied 
with semitransparent white, and flecked with brown, 
and in the possession of the other hyaline spots which 
occur in G. specularis ; expanse of wings, 1 inch 6 lines. 
Tokei (Fenton). 
As both G. mactans and G. specularis are figured 
species, there should be no difficulty in identifying 
G. fenestratus. 
98. Pericallia testacea, n.s. 
Wings above sordid ochreous, shading into testaceous 
towards the base, and speckled with blackish, crossed in 
the middle by two rather widely separated badly limited 
ereyish brown stripes, the outer one minutely undulated 
and well defined on the secondaries, excepting towards 
the apex in the male, where it expands into a diffused 
dark greyish patch; primaries with the costal third 
between the two central stripes occupied by a pale patch, 
white in the female, and between this patch and the 
apex two cuneiform costal spots, bright yellow in the 
male, but white in the female; a small brown-edged 
semitransparent whitish lunule at the end of the cell; 
body testaceous ; under surface stramineous, flecked with 
grey and banded with clay-brown; markings nearly as 
above ; female paler than male; expanse of wings— 
male 1 inch 9 lines, female 2 inches 1 line. 
Tokei (Fenton). 
Evidently a common species. 
BOARMIIDA. 
99. Hemerophila atrilineata, n.s. 
Testaceous ; the wings above covered with innumerable 
short grey-brown striz; primaries with a broad grey- 
brown ill-defined belt from the inner border to the outer 
margin below the apex; two sharply defined oblique 
jet-black lines, the inner one running from the base of 
inner margin to costa, and deeply dentate-bisinuate above 
the second median branch; the outer one slightly sinuous, 
and running from the middle of the inner margin to the 
apex ; a pale undulated submarginal stripe ; secondaries 
most densely striated towards the base; a jet-black
