NOTES ON BRITISH LEPIDOPTERA. 135 
colour; the blotch towards apex is a variable quantity, sometimes 
very well defined, but often only represented by a patch or two 
of darker scales; in the strongest marked specimens there is a 
dark transverse line from the inner edge of this blotch to inner 
margin, and a whitish submarginal line touches its outer edge, 
and intersects a dark grey cloud-like spot near the middle of the 
marginal area; the inner portion of this spot is often separated 
into two dots. 
Considerable diversity is exhibited in the composition of the 
central band, but it is hardly necessary to refer to all the minor 
modifications of this and other characters, as it will suffice for 
present purposes to mention the more striking points of variation. 
In some specimens from Ventnor the base of fore wings is tinged 
with grey, limited by a slightly darker line, and the central band 
is pale grey, enclosed and traversed by blackish lines; black 
discoidal spot distinct. Other specimens from the same locality, 
and also from Folkestone and Kastbourne, have the median 
portion of the central band rather bluish grey, and the narrow 
inner and broader outer portions tinged with brownish; the 
basal patch in these examples is almost as dark as the central 
band, and is intersected by a grey suffused whitish band; the 
outer marginal area is more or less suffused with greyish. 
Mr. Porritt very generously sent me a series of specimens from 
Yorkshire. These have a very dark grey, almost blackish, basal 
patch ; the central band is rather wider than usual, bluish black 
in colour, and the transverse intersecting lines are hardly trace- 
able ; the outer marginal area is distinctly suffused with greyish, 
and the white submarginal line is unusually distinct ; the apical 
blotch and cloud below are well defined. The hind wings are 
fuliginous grey, with a whitish double central line and a single 
submarginal line. 
I understand that this form of galiata is very local, and 1 am 
inclined to think that it is the wnilobata of Haworth, which was 
also from Yorkshire. 
Quadriannulata, Haworth, appears to be a rather uncommon 
aberration of galiata. Stephens (Ill. Brit. Hnt. Haust. iti. p. 223) 
describes it as having the ‘‘ anterior wings ashy brown at the 
base, then with two geminated waved fuscous strige, and between 
these a narrow fascia of four rounded white, spots, edged with 
black ; then a broad fuscous-ash space or fascia, terminating in 
a geminated fuscous striga, with a black spot within towards 
costa; behind this the wings are whitish, a little clouded with 
cinereous and darker shades and waves, with a small emarginate 
black spot towards apex of costa; posterior wings pale cinereous 
white, with the border rather darker. Cambridgeshire and coast 
of Devon.” 
Wood figures this form (565) and also unilobata (564) in his 
‘Index Entomologicus.’ In the last-named figure the central
