154 THE GENERA OF BRITISH MOTHS. 
The genus Sideria. The insects assigned to this genus have the palpi of moderate length, the anterior 
wings of long proportion, the front edge regularly arched, and the fringed edge indented behind the tip. There 
is only one British species. 
Sideria Achatuna (the Marbled Dog’s-tooth T, No. 4). The Caterpillar of this species is unknown. 
The perfect insect appears in June and July, and is not searce in the south of England, especially where Hawthorn 
abounds, which is probably the food of the larve. 
The genus Sericoris. The insects assigned to this species have the palpi rather short and only slightly 
projecting beyond the head. The wings are rather broad, but the anterior pair are twice as long as broad, the 
body is long, and in the males tufted. The females are smaller than the other sex. There are 14 British species 
still retained in this genus, and they are divided into three divisions, the first distinguished as ‘‘ Celypha ;” 
the second, Phiaris, and the third HLudemis, respectively so named on account of the insects assigned to 
each division approaching in character three genera established by Htibner. 
Sericoris conchana (the Silver-striped T, No. 5). This insect belongs to the first division of the genus 
(Celypha). The Caterpillar is unknown. The perfect Moth appears in July and is widely dispersed, being found 
in many widely distant places, from the New Forest to the north of Perthshire. 
The other species in this division are S. Herbana, 8. Lacunana, S. Urticana and 8. alternana. In the second 
division (Phiaris) there are S. micana and S. Bistrigana, In the third and last division (Zudemis) there are 
S. fuligana, 8S. latifasciana, 8. Dormoyana, S. Euphorbiana, 8. bifasciana, 8. litoralis, and S. cespitana, 
The genus Mixodia. The insects assigned to this genus have the palpi rather longer than the head, and 
the wings nearly twice as long as broad ; the front edge being slightly but regularly arched, and the tip rather 
pointed. There are three British species. 
Mixodia Schulziana (the Schulzian T, No. 6). This pretty insect is by no means rare if sought in the 
right localities, namely, the Moors and High Heathy districts of the north of England and Scotland. It has 
also been taken near Weybridge, in Surrey. The time of the appearance of the Caterpillar is unknown, but the 
Moth appears in June and July. 
The other two species are M. palustrana and M. Tenerana. Palustrana may be easily distinguished by 
its smaller size and the deeper brown of its markings. 
The genus Roxana. In this genus the perfect insects have the palpi longer than the head, and the wings 
more than twice as long as broad; the front edge of the wings being very slightly arched and the apex rather 
obtuse. There is but one British species. 
Roxana arcuana (the Arched T, No. 7). The Caterpillar is unknown. The Moth appears in woods 
about the end of June ; but by some it is said to be double-brooded, and to appear in May and again in August. 
Greenhithe, Hampstead, New Forest, &c., are mentioned as places where it has been recently captured. 
The ninth and last sub-family of the Tortricidw is that of the Cochylidi, containing nine British genera, 
Lobesia, Cerata, Chrosis, Dapsilia, Argyrolepia, Eupecilia, Argyridia, Lozopera and Xanthosetia. 
The genus Lobesia. The insects assigned to this genus have the palpi longer than the head, the wings 
more than twice as long as broad, the front edge slightly arched, and the tip rather acute. The females are rather 
smaller than the males, and have the fringed margin of the hind-wings gradually indented below the tip. There 
is but one British species. 
Lobesia reliquana (the Orange and Black T, No. 8). The Caterpillar of this brightly coloured little insect 
isunknown. The perfect Moth appears in May, and flies in the bright sunshine. The hind-wings of the female 
are much darker than those of the male, being of a dusky brownish gray. It is far from uncommon in the 
southern counties, but extremely rare in other parts of the country. 
The genus Cerata, The insects assigned to this genus have the palpi spread, and pointing upwards. The 
fore-wings are of long proportion, but rather blunt at the apex. There are two British species. 
Cerata Servillana (the Servillian T, No. 9). The Caterpillar of this insect is unknown, the perfect insect 
appearing in woods very early in the spring, where it may be sought as early as March. It conceals itself during 
the day among dry leaves, where it is easily secured.
