94 THE GENERA OF BRITISH MOTHS, 
nearly to the tip. The wings are delicate, rounded, and free from denticulation at the margin. The larvae are of 
rather long proportions, and have two minute spines on the last segment. The Chrysalides are formed in earthen 
cocoons or under moss. Most of the species appear to be double brooded. There are three British species. 
Cabera pusaria (the Common White Wave, No. 5). This species, like Anagoge pulveraria, is very 
abundant in woods. The Caterpillar feeds on the foliage of several forest trees, and the perfect insect appears 
in May, and again in July and August, there being two broods. 
The other species are: C. votundaria, the Round-winged Wave, rather smaller than the preceding, though 
very closely resembling it; and C. exanthemata (the Common Wave), larger than either of the preceding, and of a 
delicate cream colour instead of gray. In this last species the third band near the base of the fore wings is 
sometimes blended more or less with the next, and these varieties were made a species by Haworth, as C. 
approwimaria, Specimens more thickly powdered with the dark colour, were by the same author distinguished 
as C, arenosaria, 
The genus Aleucis, The insects assigned to this genus have the antenne simple in both sexes, and slender. 
The fore wings are pointed at the tip, and the hind wings much rounded. The Caterpillar is undescribed. The 
only British species was formerly classed as a Cleora. 
Aleucis pictaria (the Gray Carpet, No, 7). This is a very rare insect. It was at first found only in Kent, 
in the neighbourhood of Dartford, especially on a particular fence on the heath: but Colchester and Lewes have 
been lately cited as places where it has occurred. 
The genus Ephyra, The insects assigned to this genus are of exceedingly delicate structure. The males 
have the antenne bipectinated nearly to the tip. The hind wings are slightly angulated towards the middle, and 
both pairs have generally a ring-like mark near the centre. The Caterpillars are slender and have no humps, 
the head being slightly bifid. The small Chrysalides are somewhat angulated, and might be taken at a glance for 
those of some small butterfly, being attached to a branch by a knot of web at the tail, and a loop round the middle, 
Ephyra pendularia (the Birch Mocha, No. 8) is perhaps the commonest of the genus, and is found plenti- 
fully in Birch woods, but not everywhere, being somewhat local. The Caterpillar (No. 94) feeds on Birch and 
Alder, and the Moth appears in the beginning of June, and again in August, being double brooded. The 
Chrysalis (No. 44) is slung to a twig. 
Ephyra trilinearia (the Clay Triple-lines, No. 11) is by no means so common as the preceding, but is 
occasionally plentiful in Beech woods, in the North of England. The Caterpillar is described by Crew as being of 
a reddish brown colour, variegated with yellow, and as feeding on the Beech, At Halton, in Buckinghamshire, it 
has lately been taken in very great abundance; and Brighton, Lewes, Plymouth, and other places are named as 
good localities for its capture, 
The other species are: #. porata (the False Mocha), distinguished by its warm brownish colour, getting 
paler towards the edges of the wings. JZ. punctaria (the Maiden’s Blush) is a common species; it is rather 
grayish in colour, shading to ochreous, and dusted with blackish. £. omitcronaria (the Mocha) is also among 
the commonest species of this genus, It may be distinguished by the colour of the external portion of the wings 
up to the outer band being of a much yellower colour than that of the interior portion, and so’ forming a broad 
yellowish border. £. orbicwlwria (the Dingy Mocha, No. 10) is the most rare, It may be at once distinguished 
by the browner colour of the wings, in which the circular marks in the centre appear conspicuously white ; and 
also by the form of the hind wings, which at the fringed edge converge to a point near the centre. This rather 
rare species has been found receutly near Brighton, Lewes, Lyndhurst, Tenterden, and Worthing.
