86 THE GENERA OF BRITISH MOTHS. 
wherever Whitethorn grows, the foliage of which is its principal food in the larva state. The Caterpillar (No. 7) 
yaries in its general tone of colour from fawn to gray. The perfect insect appears in April, June, and August, 
there being several broods. 
The genus Curapteryx is principally distinguished, as the term implies, by the tail-like projections of the 
hind-wings of the insects assigned to it, which give them somewhat the general form of Butterflies, of the genus 
Papilio, The insects of this genus are farther distinguished by the pointed form of the anterior wings. The 
antenne are simple, or only slightly ciliated in both sexes. The Caterpillars are of long proportions, and have 
lateral projections from the posterior joints of the eighth and twelfth segments. The Chrysalis is found ina 
cocoon formed of leaves webbed together, and sometimes suspended. There is but one British species. 
Ourapteryx Sumbucaria (the Swallow-tailed Moth, No. 8) is one of the largest and most conspicuous of the 
eroup to which it belongs. The Caterpillar (No. 9) is dark reddish-brown or nearly red, variegated as represented. 
It feeds on various trees, and the Moth appears in June. It is very common in the Southern and Midland Counties 
of England, but becomes rarer im more Northern districts, and has not yet been observed in Scotland. The 
Chrysalis, contained in the suspended cocoon (No. 10), should be procured for any Collection intended to be 
tolerably complete, as it forms a very curious and interesting object. 
The genus Ludalinia, The insects assigned to this genus are very nearly allied to those of the last, and 
have a slight projection on the margin of the hind wings. They are, however, distinguished by the deeply 
pectinated antennie of the males, and also by the form of the Caterpillars, which are slightly flattened beneath, 
like those of the Catocalw, with fleshy fringe above the legs, which are twelve in number, the additional pair being 
sufficiently developed for use in walking. The pupa is formed in the ground. 
The name here used has been preferred to the “‘Metrocampa” of Latreille, as being of anterior date. 
There is but one British species. 
Eudalinia Margaritaria (the Light Emerald, No. 11). This pretty insect is far from uncommon if sought 
in the proper places,—namely, woods, or shady places where large trees abound. Its delicate colouring and 
silvery gloss make it a great favourite with Collectors. The Caterpillar is described as brownish-green, with a 
black dorsal line and a row of white dots on each side. It feeds on Birch, Beech, Hornbeam, &e. Its appearance 
is not confined to the more southerly districts, like the preceding, the neighbourhood of Edinburgh being cited as 
one of the localities in which it is found most abundantly. 
The genus £iopia. The insects assigned to this genus are closely allied to those of the last, especially in 
the preparatory stages, the Caterpillars being flattened in a similar manner. They are, however, distinguished by 
the rounded form of the wings and their semi-transparency, and by the Chrysalis, which is enclosed in a web 
among leaves. 
Ellopia Faseiaria (the Barred Red, No. 12). This pretty insect has received its specific names, both 
popular and systematic, from the broad band or fascia of deeper colour which runs across the wings. The 
Caterpillar is described as reddish-gray, paler on the back, with a series of brownish dorsal marks, which 
are partially divided into a kind of heart-like form by a dark line. It feeds on Fir, and the Moth appears 
about the end of June ; but it is rarely found except in Pine plantations, and then not plentifully. The neigh- 
bourhood of Brighton, Manchester, York, &e., aro recorded as localities in which it has recently been observed 
in some abundance.
