THE GENERA OF BRITISH MOTHS, 175 
scales, The abdomen is rather depressed. The Caterpillars have sixteen legs. There is but one British 
species. 
Psoricoptera gibbosella (the Powdered Gray, No. 7). The Caterpillar of this species feeds on Sallow in 
June. The perfect insect appears m July, and has been recently observed in the neighbourhood of Manchester, 
in Hainault Forest, and near Chesterfield. This species appears to be the same as the Anacampsis Zephyrella 
of Stephens. 
The genus Gelechia, This genus, established by Zeller in 1839, contains most of the insects formerly com- 
prised in Curtis’s genus Anacampsis. The insects assigned to this extensive genus have the labial palpi reflexed, 
and the second joint without a conspicuous tuft of hairs in a brush-like form, as in the immediately preceding 
genera, being sometimes quite smooth. The fore wings are rather elongate in some of the species, but not in 
all. The hind wings are trapezoidal and more or less indented below the tip. In the present state of our classifi- 
cation of British Micro-lepidoptera, 101 species are assigned to this genus, many of which, there can be little 
doubt, will ultimately be otherwise located. 
Gelechia terrella (the Sub-cinereous, No. 8), Though the perfect insect is one of the most abundant 
of our small moths, some uncertainty still prevails as to its preparatory stages. The Caterpillar has, however, 
been described as having the anterior segments black, with pale rings, and the hind ones pale greenish, with 
slender black streaks. The Moth is taken in woods and gardens in June, and is abundant everywhere .

The following are species that have only lately been added :—G. viscariella ; G. leucomelanella ; G. ocella- 
tella ; G. albipalpella ; G. arundinetella ; G. subdecurtella. 
The genus Parasia. The insects assigned to this genus have the second joint of the labial palpi rather 
long and scaly, and the terminal joint short and also scaly, nearly to the tip, instead of being entirely smooth and 
elongated, asin the preceding genus. The fore wings are rather long and narrow, and the hind wings distinctly 
indented below the tip. There are four British species. 
Parasia Lapella (the Dingy Straw, No. 9). The Caterpillar of this species is white, with the head brown. 
It feeds within the seeds of the Burdock in October. The perfect Moth appears in the following June and July. 
It has been recently observed in abundance at Birkenhead, and also in plenty at Kingsbury, in Middlesex. 
The other species are P. Metzneriella, distinguished by asuffusion of brown above the front and hind margins 
of the anterior wings, which are rather narrow ; P. Carli@@fla, which may be distinguished by a pale oblique 
band formed by the ground colour, and P. Newropterelia, distinguished by the deep brown colour of the veins. 
The genus Cleodora. The insects assigned to this genus have the second joint of the labial palpi furnished 
with a brush-like tuft of hairs, longer than in other genera, and projecting forward. The wings are long and 
narrow, and have long fringes, the hinder pair being deeply indented below the tip. There are two British eden 
Cleodora Cytisella (the Broom Cleodora, No. 10). The Caterpillar of this species is unknown. The per- 
fect insect appears in July, and has recently been observed in great abundance near Bristol. It is also found in 
many other localities.
