120 THE GENERA OF BRITISH MOTHS. 
hinder pair being rather angulated. The Caterpillar is attenuated in the anterior segments, and the Chrysalis 
is formed in a slight cocoon. There is but one well established British species. 
Ania emarginata (the Small Scallop, No. 18). This pretty species is placed by some entomologists in 
the genus Acidulia. The Caterpillar, according to Treitschke, is ochreous, with a broad line along the back, 
which becomes fainter towards the anterior segments. It feeds wpon Galium and Convolvulus in July, and the 
perfect moth appears in the following summer, about the same time. 
The genus Ennomos (the Aveniia of Duponchel). The single British species assigned to this genus is 
sufficiently marked in its character. The antenne are pubescent in the males. The fore wings are very sharply 
pointed at the tip, the point being followed by a deep undulation, beyond which a prominence projects nearly as far 
as the point. The hinder pair are rounded ; and in repose the wings are extended. The Caterpillar is depressed, 
has a row of fleshy filaments above the legs, which are twelve in number. The Chrysalis is found in a slight 
cocoon. Judging only from the perfect insect, it would seem that this species ought to be placed with, or near 
“the Thorns,” but the preparatory stages render it very distinct, and perhaps appropriately located in its 
present place, though I believe this position will not remain permanent. 
Ennomos flexula (the Beautiful Hook-tip, No. 19). The Caterpillar of this pretty species, the structure of 
which has been described above, is often variegated with green, brown, and white, the attenuated head and tail 
being orange-brown. It feeds on various Lichens in April and May. The perfect insect appears in June, and 
is generally found in woods or old gardens, but is rather rare. It has been recently taken in some plenty near 
Cambridge, and sparingly at Brighton, Plymouth, Dorking, and many other places.
