THE GENERA OF BRITISH MOTHS. 107 
reddish brown. It feeds on Oak, Elm, &e., and the moth appears in November. It is abundant everywhere. 
There is a pale variety, which has some of the darker marks joined, so as to give it a pied appearance 
much more striking than that of ordinary specimens ; and other varieties are entirely of the colour of the darker 
markings. 
The other three species are, O. neglectata, by many entomologists deemed a mere variety of the preceding ; 
0. autumnaria, more glossy than OQ. dilutata, with the front wings rather more pointed and smaller; and 0. 
Jjiligrammaria, the wings of which are pale gray, with several transverse wavy lines forming a broad central 
band, which is pale in the centre. Both 0. wutumnaria and 0. filigrammaria are northern species. 
The genus Acasis, of Duponchel, contains but one British species, which has been detached from Mr. 
Stephens’ genus Lobophora, on account of the existence of minute characters which appear to warrant the new 
location. The insect is, however, still retained in the genus Zobophora by Mr, Stainton and many other 
entomologists, 
Acasis viretata (the Brindle-barred Yellow, No. 7). This pretty insect may be considered rare. . The 
Caterpillar, according to Hiibner, is dull yellow, spotted with orange on the back. It feeds on the foliage 
of the Privet ; and the perfect insect appears in May. It has been recently taken at Lewes, Lyndhurst, 
Cambridge, &e. 
The genus Lobophora. This genus includes the species popularly known as the Seraphims. The antennse 
of the males are simple, or nearly so; the palpi are short and bent abruptly upwards. The hind wings of the 
male have a raised lobe at the base, fringed at the edge, which in some of the species is very conspicuous. 
The Caterpillars are smooth, with the head flat and the tail slightly bifid. They feed on various trees. The 
Chrysalis is subterranean. 
Lobophora lobulata (the Early Tooth-striped, No. 8). This species has been selected for illustration 
as best exhibiting the lobe of the hind wings. The Caterpillar (No. 9) feeds on the Sallow in August, and the 
perfect insect appears in the following month. It has been recently taken in abundance at Manchester, York, 
and in districts much farther north. It is generally found on palings and the trunks of trees. 
The other species are: LZ, polycommata (the Barred Tooth-striped), which has the front wings grayish, 
with the basal blotch rather darker. This is a very local insect. LZ. hewaptera (the Seraphim), which has the 
front wings of a pale ochreous tone, with transverse cloudy bands of pale blackish, powdered with darker specks, 
L. sexalisata (the Small Seraphim), which is a much smaller and more fragile insect than any of the other 
species, and is of a pale buff tone, with delicate, but distinct, bands of a grayish colour, 
The genus Eupithecia is one of the most extensive of the great family of Geometride. It contains a large 
proportion of the pretty class of Moths popularly known as Pugs. One of the general characters of this genus 
is the uniformly small size of the insects assigned to it. The antenne are alike in both sexes, or those of the 
males are only slightly pubescent. The abdomen is generally crested. The front wings are narrow, and 
the hind wings small in proportion to the front. The Caterpillars are short and stiff, and the back has 
generally a series of strongly defined markings. They often feed on the flowers or seed-yessels of plants rather 
than on the foliage. The Chrysalis is slender and very pointed. There are thirty-seven described species, and, 
with the one newly named by Mr, Doubleday, thirty-eight. 
Eupithecia linariata (the Beautiful Pug, No. 10). This beautiful little insect is still rather rare, though 
several new localities have been discovered in which it is found in some plenty. The Caterpillar (No. 11) 
feeds in spring upon the flowers or on the seed-yessels of the common Toadflax (Linaria vulgaris), and the moth 
appears in the following June and July. 
Lupithecia irriguata (the Marbled Pug, No. 12), This is another very pretty species, the ordinary chaste 
brown tones of which are sometimes beautifully heightened, especially in continental specimens, by a flush of 
pink. The Caterpillar is at present unknown. This is a rare species, but it has been recently taken at Lyndhurst 
and one or two other places, besides the localities in the mountains of South Wales where it was first observed. 
Eupithecia viminata, the species recently named by Mr. Doubleday, is rather obscure in its markings, 
but much sought just now by collectors, both on account of its rarity, and as being decidedly a well-defined 
new species,
