20 THE GENERA OF BRITISH MOTHS, 
The genus Peridea is distinguished from the other genera of Notodontida principally by its superior size. 
The antenne are bipectinated in the males. The fore-wings have a slight projection from the inner margin. 
The Caterpillar has no protuberances. There is but one British species. 
Peridea Trepida (the Great Prominent, No. 1) appears in May and June, but is not common. The 
Caterpillar, No, 2, is found on Oak in August and September. It has been captured recently at Manchester, 
York, Epping, and other places. 
The remarkable genus Endrvomis belongs to a separate sub-family of Notodontide, termed Endromidi, as 
exhibiting some very distinctive characters ; such as its remarkably large size, and the semi-transparent character 
of its broad and finely marked wings. The antennz are bipectinated both in the males and females. 
Endromis Versicolor (the Kentish Glory) is represented at No, 3 and 4, 3 being the male and 4 the female. 
Till within the last few years, this fine Moth has been considered one of the choice rarities of an English 
collection ; but it has lately been taken in such numbers in the Rannoch Woods, near Perth, that it is now 
found in every cabinet, though as rare as ever in its old haunts in Kent, and a few other southern counties. It 
appears in April. The Caterpillar of the Kentish Glory (No. 5) feeds on Birch, Lime, and Hazel, in June 
and July. 
The genus Saturnia belongs to the family, Bombycide, according to the arrangement of the collection in the 
British Museum. The antenne in this genus are four-pectinated at each joint. The larve of the European 
species are naked ; each segment being furnished with a ring of tubercles emitting tufts of short bristly hairs. 
No. 6, Plate 6, is Saturnia Pavonia-Minor, so named to distinguish it from the S. Pavonia-Major 
of the Continent of Europe and of America. It is one of our handsomest Moths, and by no means rare, being 
very generally and rather plentifully distributed. The female is larger than the male, but the markings and 
general colouring are paler. It is subject to extreme variations of colour; Mr. Bond, whose fine collection 
is well known, having a specimen in which the fine ringed spots or ocelli are entirely absent, leaving the large 
cream-coloured space, in which they are generally found, entirely without mark. It appears in May, and again 
in August. The Caterpillar of the Emperor-Moth, No. 6, is often found on Heather in the autumn, and 
sometimes on Apple and Willow trees. This insect, as stated, is common, and very generally distributed. 
The genus Gastropacha also belongs to the family Bombycide. It is distinguished by strongly curved and 
pectinated antenn in both sexes. The remarkable effect produced by the dilated margins of the hind wings 
extending beyond the fore wings when the insect is at rest, has been thought to give to them the appearance 
of brown leaves, and hence the specific names, Quereifolia and Iicifolia. The Caterpillars have singular velvety 
bosses on the second and third segments, from which issue long and slender tufts of hair; the first and last 
segments having similar tufts of hair, but not the velvety bosses. 
Gastropacht Quercifolia (the Oak, or Oak-leaf Lappet-Moth, No. 8) appears in the beginning of July. 
At No. 9 the same insect is represented at rest, showing the singular effect of the extension of the hind- 
wings beyond the anterior ones. The Caterpillar of the Oak-leaf Lappet-Moth (No. 10) feeds on Grasses as well 
as Trees, and is found in May and June. It is widely distributed. 
G. Micifolia (the Small or ‘ Scarce” Lappet-Moth, No. 11). This species (though long reported as 
British) has been extremely scarce till within the last few years. The three specimens in the British Museum, 
from one of which (a female) my drawing was taken, are all remarkably beautiful. The Caterpillar of 
G, Micifolia (No. 12) feeds on the Sallow in June and July, and passes the winter in the pupa state, the Moth 
appearing in the following May. It is found in high moorland districts, and its recent capture is recorded at 
Cannoch Chase and near Sheffield. 
G. Populifolia, another species, as large as G. Quercifolia, was formerly reported as British, but is no 
longer found in our catalogues. If, however, any collector should meet with it, he may know it by its bright 
light ochreous colour, and the less curved antenne, which at once distinguish it from @. Quercifolia,
