166 THE GENERA OF BRITISH MOTHS. 
Caterpillar is described as gray, with the head blackish, the second segment being also black, and the third and 
fourth having cach two black dots. The case is grayish-green, and is three-sided. It is found on palings and 
trunks of trees in March. Bristol, Manchester, Plymouth, &e., are cited as localities in which this Moth has 
been recently taken. 
The other species, S. Douglasi’, is thought by some to be only a-variety of the preceding, but Mr. 
Eddlestone, as cited by Mr. Stainton, believes that there is even a third distinct species occurring near 
Manchester, which appears in May. The Caterpillars of this supposed distinct species are found under stones on 
the Moors. 
The genus Diplodoma. The insects assigned to this genus have the antenne ciliated in the males, and 
slightly toothed in the females. There are no maxillary palpi. The females have perfectly developed wings, 
but are generally less than the males. The Caterpillars are case-bearing, as in the two preceding genera, but 
the case is distinguished by being clothed in an outer covering. There is but one British species. 
Diplodoma marginepunctella (the Dotted Border, No. 3). This pretty species is marked with pale yellow 
dots, which in some lights hayé-a golden gloss difficult to represent in a drawing. The Caterpillar is deseribed 
as dull-whitish, with the head and second segment brown. It is said to feed on Fungi in September and October, 
The perfect insect appears in June and July. It was formerly taken at Ripley, and considered extremely 
rare, but many places are cited for its recent capture, as Manchester, Plymouth, York, and many other 
localities. 
The genus Nysmatodoma. The insects assigned to this genus have the head very hairy, the antenne 
of the male strongly ciliated, no maxillary palpi, and the labial palpi short. The female has narrower wings 
than the male. The Caterpillar forms a case, but it is without an additional external covering, and is rather 
short. There is but one British species. 
Xysmatodoma melanclla (the White-spotted Black, No. 4). The Caterpillar of this species is described as 
dull-yellowish, and the head and the second segment black ; the third and fourth segments being respectively 
marked with four black dots. It feeds on Lichen, and is found on the trunks of trees and on palings, in April 
and May. The perfect insect appears in June, and has been recently taken in several places in considerable 
abundance, especially in the neighbourhood of Manchester. It is generally found where Elm trees abound. 
The genus Ochsenheimeria. The insects assigned to this genus have the antenne rather thick, and some- 
times clothed with seales to the middle. The fore-wings are oblong, and have a rough appearance from the 
semi-erect growth of the scales. The Caterpillars are without cases, and burrow in the stems and roots of Grasses. 
There are three British species. 
Ochsenheimeria vacculella (the Spotted Bull, No. 5). The hind-wings of this species are devoid of scales, 
semi-transparent towards the base. The Caterpillar is unknown. The perfect insect appears in July, and has 
been recently taken at Daventh, Manchester, &c. It frequents houses, while 0. Bisontedla is generally found on 
heaths. 
The second species is Ochsenheimeria Bisontella (the Little Bull), This species has received its popular 
name, the Little Bull, from the broad tuft of hair at the front of the head, which at once suggests the idea of a 
bull’s head, or rather, perhaps, accompanied as it is by the hairy palpi and the scaly horns of the antenne, 
it represents more nearly the miniature head of a Bison, from which no doubt originated the specific name 
Bisontellu. O, Birdella, the third species, is found in pastures, 
The genus Luplocamus. The insects assigned to this genus are larger than those of either of the imme- 
diately preceding genera, The head is hairy, as in the last, and the males have the antenne partially clothed 
with tufts of fine hairs, which makes them appear pectinated. The maxillary palpi are folded, and the labial 
palpi have the terminal joint erect. The wings are much deflexed in repose. The Caterpillars feed upon Boleti. 
There is only one British species. 
Euplocamus Bolcti (the Agaric, No. 6). This is a very prettily marked species. The Caterpillar feéds on 
Fungi. The perfect insect appears in July, but is very searce. It was formerly found in Birch Wood, Wanstead 
Flats, &e. The females generally rest upon the trunks of Aspens, and, if watched, the males may be found 
fluttering round them at dusk. This species has heen recently taken in the New Forest, and in Epping Forest.
