34 THE GENERA OF BRITISH MOTHS. 
Psyche Fusca (the Brown-Muslin Moth, No. 3) is a very elegant little insect. The wings of the male 
are of a delicate bluish black, and semi-transparent. The female (No. 4) is entirely wingless. The 
Caterpillar makes a case, which is represented at No. 43. The Chrysalis resembles, in its general form, that 
of the house-fly tribe, being nearly oval, without any mark of wing-case, but ribbed with several joint-like 
articulations from end to end. 
The genus Fumea differs from Psyche in its broader and more hairy wings, and the antenne of the 
males are very strongly pectinated. There are three British species. 
Fumea Nitidella (the Shining Chimney-sweep, No. 5) has the wings of the male of a light shining 
brown, the hind wings being generally of a lighter tone, though sometimes darker. The Caterpillar forms 
a ease much like that of P. Fusca, and is represented at No. 6. 
F. Radiella (the Chimney-sweeper’s Boy) is the smallest of the genus, not much more than half the 
size of the preceding species. The wings of the male are semi-transparent, black, andthe antenne are only 
slightly pectinated. 
F. Reticella (the Netted Chimney-sweep) is nearly as small as the last-named species, from which it 
is distinguished by a beautiful minute network of soft brown lines extending all over the wings. 
The genus Nudaria is grouped with the Psychide, from the similarity in form and character of the 
perfect insect, which is, however, winged in both sexes, and the Caterpillars do not form portable cases. In 
fact, all the species of Nudaria seem, on the whole, more closely allied to the Lithosiide. Nudaria Munduna (the 
Muslin) is represented at No. 7, and the Caterpillar, which is common and feeds on lichens, at No. 8. 
NV. Senex (the Round-winged Muslin, No. 9) is distinguished by the greater whiteness and delicacy 
of the wings, and by the minute black specks with which they are marked. 
The sub-family Limacodidi contains two genera, in many respects allied to those of Psychidi, but. still 
more remarkable in respect to the footless Caterpillars, of singular shape, which distinguish both the genera 
of which it is composed. 
The genus /eterogenea, so named in reference to the unusual form of the Caterpillars, contains cnly 
one species, H. Asellus, which is remarkable for the triangular form of the wings, from which it has received 
its popular name, the Triangle, but which are scarcely sufficiently marked in the illustration (No. 10). The 
Caterpillar (No. 11) feeds upon poplar, and is very rare; it has, however, been found in the New Forest. 
The genus Limacodes contains only one species, Testudo (No. 12). This genus was formerly considered a species 
of Heterogenea, from which it was separated on account of the different form of the wings. Our great English 
entomologist, Haworth, named this genus Apoda, that is, footless, in allusion to the peculiar structure of the 
Caterpillar, which resembles that of H. Asel/us, but is somewhat larger. The wings of the female (No. 13) are 
more faintly marked than those of the male. The Caterpillar feeds on oak, in September, and is found some- 
times in the Kentish woods. There are several North American species of this curious insect. 
The second sub-division of Moths, Lepidoptera Nocturna, commences with the family of Lithoside, containing 
nine genera, which, with two exceptions, appear to group together very homogeneously. The Motlis of this small 
family have the body narrow, the antenne generally slender, and simple in both sexes ; but occasionally slightly 
pectinated in the males. The wings are narrow and elongated, of delicate texture, and their flight is short and feeble. 
The genus Callimorpha is one of those which, from the breadth and triangular form of the wings, seems 
hardly to belong to the family in which it is placed, though it has many affinities with it. It contains only one 
British species, C. Jacobaw (the Cinnabar Moth), represented at No. 14. It is a very handsome insect, and has the 
under side of the wings exactly like the upper, both in colour and in the distribution of the markings, which is very 
unusual either in Moths or Butterflies. The Caterpillar (No. 15) is very common, and is found, in the summer 
months, feeding in preference on the common groundsel. 
The genus Miltochrista is distinguished from the preceding by the smaller size of the insects of which it is 
composed, by the more hairy though more slender body, and by the thicker clothing of hair of the Caterpillars. 
Milt.christa Miniata, the Red Arches, is figured at No. 16, The Caterpillar feeds on lichens and various trees, 
the perfect insect appearing in June. It is considered rare, though found in various parts of the country. 
The genus Hulepia is distinguished by the pectinated antenna of the males, and by the streaky markings of
