THE GENERA OF BRITISH MOTHS. 35 
the anterior wings and generally deeper colour of the hinder ones, the Caterpillars being of similar character to 
those of other Lithoside. It contains two British species. 
Eulepia Grammica (the Feathered Footman, No. 17) is one of the rarest of the Zithoside, the Caterpillar 
(No. 18) feeds on various plants and shrubs in May, and the perfect insect appears in July. 
Eulepia Cribrum is equally rare, but has been found on the heathy lands of Hampshire, and other localities. 
It is distinguished from Grammica by having the dark stripes of the anterior wings broken up into detached marks, 
and the hind wings are of uniform dark brown with lighter fringe. 
The genus Deiopeia, one of the most distinct from the other Lithoside, is distinguished by a peculiarity of 
marking not found in any other genus. It contains but one native species, Deiopeia Pulchella (No. 19), which is 
one of the most elegant of British Moths. The Caterpillar (No. 20) appears to feed in preference on the field 
forget-me-not (IMyosotis Arvensis), the perfect insect appearing, in this country, in September and October. It is 
very rare. 
The genus Lithosia, which forms the type of the family to which it belongs, contains eight species, all 
exhibiting the same general character as Lithosia Aureola, the one selected for illustration. 
Lithosia Aureola (the Orange Footman, No. 21) is rare, but occurs in many places in the south of England, 
especially where exotic trees of the pine family have been planted, on which the Caterpillars feed in May and 
June, and the perfect insect appears in July. It is a very common insect on the Continent. 
L, Helvola (the Buff Footman) is somewhat smaller than Auwreola, the front wings dove colour, the hind 
wings pale buff. 
L. Flava (the Straw-coloured Footman) is about the size of the preceding ; all four wings being of a pale 
buff or straw-colour. 
L. Complana (the Scarce Footman) is of similar size, but the anterior wings are grey, with a stripe of 
pale yellow along the front, the hind wings being straw-colour. 
L. Lurvideola (the Common Footman) is much like the preceding, which is, possibly, a rare variety. It is 
often mistaken for it by young collectors. 
L. Griseola (the Dun Footman) is rather larger than any of the preceding. The front wings are pale grey, 
with a very narrow line of straw-colour in front ; the hind wings buff. 
L, Luteola (the Small Footman) has all four wings pale yellow, like L. Mlava, but is much smaller. 
L. Muscerda (the Spotted Footman) has both front and hind wings of a pale soft grey, the front wings being 
distinguished by a line of pale yellow along the front, and several small black specks, the hind wings having a 
broad but interrupted central band of pale buff. It is a very distinct species. 
The genus (nistis is of true Lithosian character, but the insects it comprises are both larger and handsomer, 
and differ materially in the colouring of the two sexes, as shown in figures of (nistis Quadra (the Large Footman), 
the only native species, 23 (misnumbered 43) and 233. The Caterpillar of this handsome insect (No, 24) feeds 
on oak, birch, etc., in June, and the Moth appears in July. It is a common species. 
The genus Afolmis differs in appearance from the other Lithoside, in the dark colour of the solitary species on 
which it is fuunded, and some minute anatomical distinctions. A. Rudricollis (the Red-necked Footman), so named 
from the small red mark close to the head, is a very pretty insect. The Caterpillar, No. 26 (misnumbered 23), 
feeds on lichens and various trees in spring, and the Moth appears from May to July. It is far from common. 
The genus Cybosia is distinguished by more opaque and more triangular-shaped wings than the true Lithosidw. 
The only species, C. Mesomel/a (the Four-spotted Footman, No. 27), is not rare in favourable localities. The Cater- 
pillar, which is short and thick, of greyish colour, with a reddish head, feeds on various plants. The Moth 
appears in June and July. 
The genus Endrosa has the anterior wings of the same form as those of the preceding genus, but they are 
semi-transparent. The only British species admitted in the Museum Catalogue is Z. Irrorella (the Dew Moth, 
No. 28). There is, however, a very singular variety in which the dark spots on the front wings are conspicuously 
united, forming the letters I VI. The Caterpillar (No. 29) feeds upon lichens, and the Moth, which is rare, 
except in the south of England, appears in June and July. The species, once distinguished as Roscida, is not now 
admitted to the list of Native Moths.
