THE genus Ypsolophus. The insects assigned to this genus have the second joint of the labial palpi 
formed like a brush, from which the third joint issues, long and slender like a single protruding bristle. The 
wings are rather elongate and large in proportion to the body, the fringes being of moderate length. There are 
three British species. 
Ypsolophus fasciellus (the Long-winged, No. 1). The Caterpillar of this species is described as pale 
yellowish gray, with three greenish lines on the back ; the head and second segment dull orange. It feeds on 
the Sloe in September, the perfect Moth appearing in the following May. It was formerly taken near London, 
at Darenth Wood, New Forest, &c., but was considered rare. It has been recently captured at Lewes and 
Cambridge. 
The other species are Y. Juniperellus, which is more of a gray tone in the front wings, and Y. marginellus, 
which is more buff than /asciellus. 
The genus Aplota. The insects assigned to this genus have the labial palpi similar to those of Ypsolophus, 
but without the projecting bristle, the terminal joint being concealed in the scales of the second. The fore wings 
are somewhat linear with the apical margin, obliquely truncate. There is but one British species. 
Aplota palpella (the Dingy Streak, No. 2). The Caterpillar of this species is undescribed. The perfect 
insect oceurs in August, and has been taken at Ripley, and more recently in Hainault Forest. 
The genus Nothris. The insects assigned to this genus have the labial palpi closely similar to those of the 
insects belonging to the genus Ypsolophus. The fore wings of rather narrow proportion, and the fringes are not 
variegated. There are two British species. 
Nothris Durdhamella (the Durdhamian, No. 3). The Caterpillar of this species has the anterior segments 
blackish, the rest of the body being yellowish white, with brown lines on the back. It feeds in rolled-up leaves 
of different species of Thyme, in June. The perfect insect appears in July. It has been recently taken at 
Teignmouth, Darenth Wood, Deal, and other places. 
The other species is N. berbascella, which is much paler in the general colour, and the Caterpillar, which 
is dull brown with the head and next segment black, feeds in leaves of the Verbascwm. 
The genus Sophronia. The insects assigned to this genus have the palpi as in Ypsolophus. The front edge 
of the wings has generally a light streak, so that when they are closed in repose, being very narrow, the general 
appearance of the insect is that of a short dark line with a white edge on each side. There are two British species. 
Sophronia parenthesella (the Parenthesis, No. 4). The Caterpillar of this species, though the moth was 
well known in the time of Linnus, still remains undescribed. The perfect insect appears in June and July, and 
has been recently taken in great abundance at Manchester, and in sufficient plenty at other places.
