The male of the fox moth is very similar to the female, but differs in being of a somewhat richer colour, smaller, and having the antenne 
pectinated. The male of L. Trifolii, as exhibited in the plate, has a pale band on the hind wings, a peculiarity upon which a separate species 
has been founded ; but as I have found none but males so distinguished, I am inclined to think it a mere sexual difference. The two varieties 
of L. Roboris have also been by some made two species. L. Quercus is from Hiibner’s figure, and L. Dumeti and the dark female are in the 
British Museum ; L. Dumeti beinga foreign specimen. The others are all from the beautiful specimens furnished by Mr. H. Doubleday. The 
young caterpillar of the fox moth, the cocoon, and the caterpillar of L. Trifolii, are from Hiibner ; the other two are from nature. In the 
present plate a few leaves of plants are introduced merely for the purpose of exhibiting the caterpillars more conveniently. H. N. H.

This group has the wings entire, and comparatively elongated and opaque, the hinder ones rounded; the 
abdomen of neither sex regularly tufted at the tip, but bifid in the males; the palpi minute, and not porrected 
like a beak ; the antenne deeply bipectinated in the males, straight and serrated in the females. The males 
fly with amazing rapidity by day. The larve are solitary in their habits, and clothed with long hairs (whence 
the generic name, derived from the Greek) ; when alarmed they curl themselves up in a ring, when the pale

annulations of the body become distinct, as represented in our fig. 3, whence they have gained the name of the 
‘devil’s gold rings.’ The nomenclature of the species has been greatly confused, varieties having been often

regarded as distinct species. Dr. Boisduval, in his new work, gives only L. Rubi, Quercus, and Trifolii, as 
natives of central and northern Europe.

This species varies from 2} to 2° inches in the expansion of its fore wings, which, as well as the body and 
hind wings, are of a fox colour, (whence the English name of the species), the fore wings having two scarcely 
oblique pale stripes, variable in their position, across the middle ; and the fringe of the hind wings is whitish. 
The female is paler, but similarly marked. 
The caterpillar when young is blackish and velvety, with golden rings (fig. 3), but it afterwards becomes 
ferruginous above and black beneath, with black rings edged with fulvous and reddish hairs; it forms a long 
and nearly transparent cocoon, through which the chrysalis can be seen. It feeds on the bramble, and appears 
in the autumn; the perfect insect being produced at the beginning of the following summer. It is not an 
uncommon insect, but is difficult to rear.
