THE GENERA OF BRITISH MOTHS. 179 
CEcophora Woodiella (the Woodian, No. 9). This beautifully marked insect is the rarest of the genus to 
which it belongs, and indeed may be almost considered unique, as only a single specimen appears to have been 
taken—the one described by Mr. Stephens as having been captured by Mr. R. Wood in the month of June, on 
Kersall Moor, near Manchester, now some years ago. As the time of its appearance is thus known, collectors 
should look out for it at the proper season in likely situations, and other specimens will doubtless reward a 
persevering search. It is almost the only species of the genus which is very rare, most of the others, many of 
which are very pretty, being sufficiently plentiful, though some few are rather local. 
The other species are, @. minutella; @. flavimaculella ; @. tripuncta; C. similella; CG. augustella ; 
@. grandis; G. formosella ; @. lunaris; (@. Lambdella ; G2. subaquilea; @. Panzerella ; CG. tinctella ; 
G. unitella ; @. flavifrontella ; CE. fuscescens ; and G2. psewdo-spretella. Many of these are very prettily marked 
with bright tones of yellow, brown, or ochre, and several of them are very common, as minutella and pseudo- 
spretella, for instance ; while formosella, grandis, and one or two others, are comparatively scarce. 
The genus (Lgoconia. The insects assigned to this genus have the head tufted at the back, the antenne 
rather short and robust, the wings of long proportion, and the hind wings not transparent at the base. There 
is only one British species. 
Egoconia quadripuncta (the Four-spotted, No. 10). The Caterpillar of this species is unknown. The 
perfect Moth appears in August and September. It has been recently observed in the neighbourhood of Bristol 
in some profusion, and has been taken near London in houses. 
The genus Endrosis. The insects assigned to this genus have the head devoid of the posterior tuft which 
distinguishes the last genus. The antenne are rather long and slender, and the wings are long, the hinder pair 
being transparent at the base. There is but one British species. 
Endrosis fenestretia (the White-shouldered, No. 11). The Caterpillar of this species is nearly white, with 
the head and second segment brown. It feeds on decayed wood and other waste substances in December and 
January, and the perfect Moth appears near the same time. It is very common in houses. 
The genus Butalis. The insects assigned to this genus have the head blunt, broad, and retracted. The 
antenne are slightly ciliated in the males. The palpi are short and pointing upwards. The body is short and 
thick. The fore wings are long and the hind pair pointed ; in repose they are folded closely over the body which 
they entirely conceal. There are nine British species. 
Butalis grandipennis (the Great Rayen-feather, No. 12). The Caterpillar of this species is dark olive 
green, with a pale line along the back and a darker line on each side. The head is brown and the whole body is 
sprinkled with black specks. It feeds on Furze in January and March. It has been recently observed in great 
profusion near Birkenhead, Bristol, Manchester, Wimbledon Common, &e., &c. 
The other species are, B. fusco-cenea; B. senescens; B. fusco-cuprea; B. Cicadella; B. variella; B. 
Chenopodiella ; B. torquatella ; and B. incongruella. Most of them are of a dull, dark greenish or brownish 
tone, some of the species having a few white or yellowish marks. 
The genus Pancalia. The insects assigned to this genus have the head retracted and obtuse. The palpi 
are reflexed, and have the seeond joint smooth, and the terminal joint pointed. The wings are narrow. There 
are two British species. - 
Pancalia Latreillella (the Latreillian, No. 13). This handsome insect appears in June, but is not common. 
It has been recently observed near Edinburgh, and at Epping, Lewes, and Plymouth. The female may be 
distinguished by a ring of pure white near the tips of the antenne. 
The other species, P. Lewwenhoekella, is much more common than the preceding. It is very like in 
colour, but invariably smaller, and both sexes haye the rings of white near the tips of the antenne.
