98 THE GENERA OF BRITISH MOTHS. 
Eubolia mensuraria (the Small Mallow, No. 8). This pretty, hut common insect is sometimes called 
the Aurelian’s plague, from its excessive abundance, filling his net to the exclusion of rarer and more desirable 
specimens, The Caterpillar has not been accurately described ; but it is said to be of a yellowish green colow, 
and to feed on Grass. The perfect insect appears in July and August, and is common everywhere. 
The other species are :—E. cervinata (the Mallow Moth) which may be distinguished by its somewhat larger 
size, and by its much browner colouring, the markings being very similar to the preceding; #. meniatu is 
about the size of the first species, but browner, with some of the bands variegated with straw colour. Only one 
specimen has yet been captured of this rare insect ; it was taken near Carlisle. 
The genus £usebia. To this genus of Duponchel a single British species has been assigned, which 
is generally placed in Zubolia, the Lareniia of Treitschke. The wings are more rounded than in the preceding 
genus, and the antenme of the males of this genus only slightly pectinate. The Caterpillars are thick, and 
striped. 
Lusebia bipunctaria (the Chalk Carpet, No. 33) is a very local, but yet abundant species. The Caterpillar 
is of a pale brownish gray colow, with darker lines. It feeds on Clover ; and the perfect insect appears in 
June, and is very plentiful in lime and chalk districts. Many places are cited where it appears sometimes 
in extreme abundance, as Lewes, Cambridge, Eden, Dene, Dover, &c. 
The genus Erinobia. A species, formerly placed in Treitschke’s genus Zarentia, has been, for slight 
distinctions of character, assigned to this genus; these are the curious dottings on the nervures of the anterior 
wings, the nearly simple antenne, &c., &e. Mr. Westwood, as early as 1845, suggested the propriety of 
removing Larentia multistrigaria from the genus Larentia, 
Erinobia multistrigaria (the Mottled Gray, No. 4) was formerly considered a rare insect. The Caterpillar 
is described by Shiel as dark with lateral markings of brown; it feeds on Bedstraw. The perfect insect 
appears in March, and used to be taken on heaths near London, and also in Norfolk. It is now found 
abundantly at Birkenhead, Bristol, Lewes, Manchester, and Plymouth, and in some plenty in many other places. 
The genus Venusic. In the insects assigned to this genus, the antenne of the males are slightly 
bipectinated, the pectinations being rather longest at the tips. The abdomen is slender, and the wings rather 
rounded and free from indentations. The preparatory stages are unknown. There is but one British species. 
Venusia Cambriea (the Welsh Wave, No. 5). This was formerly considered a very rare insect, the 
Devil’s Bridge in Cardiganshire being the only locality recorded for its capture. The Caterpillar is unknown ; 
but the perfect insect appears in June or July. It is now found in some plenty at Huddersfield, the Lake 
Districts, Manchester, Stowmarket, and Sheffield. 
The genus Corenia. The insects assigned to this genus have the antenne of the males either pectinated 
or pubescent. They have generally a series of spots at the side of the abdomen. The Caterpillars are ten- 
footed. The Chrysalides are subterranean. There are eleven British species. 
Coremia didymata (the Twin-spot Carpet, No. 6) is widely dispersed, but was once thought a very 
local species. The Caterpillar is, according to Sepp, grass green with a white line at the side. The perfect 
insect appears at the end of July, the female being much paler than the male. It now is considered by 
practical entomologists to be plentiful everywhere. 
Coremia fluctuate (the Garden Carpet, No. 7). This is © common species. The Caterpillar (No. 8) 
feeds on several garden plants—Horse-radish, Cabbage, &e. The perfect insect appears throughout the summer 
in gardens, and even in houses, in the country. 
Coremia montanata (the Silver-ground Carpet, No. 9). This handsome species is abundant everywhere. 
The Caterpillar is said to be dull whitish, with several gray-brown stripes, and a white line above the legs. 
It feeds on Primrose, in woods, where the perfect insect appears in June. 
Coremia miaria (the Green Carpet, No. 10). This beautiful insect is almost as abundant as the preceding. 
The preparatory stages are unknown. The perfect insect appears in woods and shady lanes in June. 
The other species are the following: @. salicata (the Striped Twin-spot Carpet) closely resembles 
C. didymata, Wut is much smaller. C. ferrugata (the Red Twin-spot Carpet) has the dark portions of the 
wings much deeper than in the two last-named species, and the light bands clearer ; in size it is less than the
