174 THE GENERA OF BRITISH MOTHS. 
The genus Enicostoma. The insects assigned to this genus are principally distinguished from allied genera 
by the anatomical structure of the palpi, the labial palpi being arched, the second joint scaly, and the point 
smooth and ascending. There is but one British species. 
Enicostoma lobelia (the Thunbergian, No. 3). The Caterpillar of this species is pale green, with a paler 
line on each side of the back. It feeds on the under side of Sloe leaves in August and September. The perfect 
insect appears in the following June. It has been recently observed in some abundance at Cambridge, Lewisham, 
and other places. 
The genus Phibalocera, The insects assigned to this genus have the antenne longer than the wings. 
The labial palpi have the second joint scaly, and the terminal one slender and pointed. The Caterpillars form a 
flat web on the under side of leaves. There is but one British species. 
Phibalocera Quercana (the Long-horned), Another insect having been figured at No. 4, instead of 
P. Quercana, it will be necessary to describe the present species in detail. The antenne are nearly a fourth longer 
than those of the other species of this genus. The fore wings are rather arched in front and somewhat square at 
the fringed edge, and slightly comeave ; the hind wings are rather convex at the fringed edge, and the fringes not 
very deep. The front wings are pale rosy gray with obscure darker markings, getting darker near the front edge, 
which has a whitish streak at the base, an elongated white spot near the middle, anda white streak at the 
tip. The hind wings are pale dusky cream colour with grayish fringe. The Caterpillar of this species is 
described as pale green, with a dark dorsal line edged with white. In May and June it feeds in a web on 
the under side of the leaves of the Oak, the Apple, and other trees. The perfect insect appears in July 
and August, and is very common. It has been recently noticed in great abundance at Bristol, Birkenhead, 
Plymouth, Tenterden, &e. 
The genus Exeretia. The insects assigned to this genus have the antenne of the males pubescent. The 
labial palpi are peculiar, having the second joint furnished beneath with a small tuft in the form of a brush. The 
front wings are slightly sinuate in front, and the fringe short. 
Exeeretia Allisella (the Rare Exeretia, No. 5). The Caterpillar of this species is at present undescribed. 
The perfect insect appears in July. It is considered rare, but has been taken at Birkenhead, Manchester, and 
other places, especially in some localities on the coast of Norfolk. My drawing is made from a specimen in the 
British Museum. 
The genus Depressaria, This is a very extensive genus, containing no less than thirty-eight species, 
several of which differ rather materially from the generic type. The general characteristics are the following :— 
Antenne simple, or only slightly pubescent in the males ; the labial palpi have the second joint furnished with a 
prush-like tuft of hairs. The abdomen is flat, with projecting scales at the sides. The fore wings are moderately 
long and slightly rounded at the tips. The hind wings are sometimes indented at the fringed margin near the 
angle next the body. The Caterpillars have sixteen legs. 
Depressaria Alstremeriana (the Alstreemerian, No. 6), The Caterpillar of this species is described as green, 
with three darker lines along the back. It feeds in July in folded leaves of Hemlock. The perfect insect 
appears in August, and has been recently ebserved in great abundance at Scarborough, Neweastle-on-Tyne, and 
many other localities. It is found most abundantly in Osier grounds, 
The other species are so numerous that in the restricted limits of this work it will be impracticable to do 
more than give a list of their names, which are as follows :—D. costosa; D. liturella; D. pallorella; D. 
bipunctosa ; D. Umbellana ; D. assimitella ; D. nanatella ; D. atomella : D. arenclia ; D. propinquella ; D. subpropin- 
quella ; D. ciniflonelia ; D. purpurea ; D. Capreolella ; D. Hypericella ; D. conterminella ; D. Angellicella ; D. Car- 
duella ; D. ocellana; D. Yeatiana; D. applana; D, ciliella; D. granulosella ; D. rotundella ; D. depressella ; 
D. Pimpinelle ; D. albipunctella ; D. emeritella ; D. pulcherrimella ; D. Douglasella ; D. Weirella ; D. Cheero- 
phylli; D. ultimella ; D. nervosa ; D. Libanotidella (this is the recently discovered species taken at Newhaven) ; 
D. badiella ; D. Pastinacella ; and D. Heracliana. 
The genus Psoricoptera. The insects assigned to this genus have the labial palpi reflexed, and the 
second with a brush-like tuft of hairs, The fore wings are of rather long proportion, and have raised tufts of
