Tue genus Xanthia, the type of the Xanthidi, is distinguished by thie slight ciliation of the antenne of the males on 
the under side, by the obliquely-projecting palpi, and by the slightuess and somewhat flattened form of the abdomen; 
also by the angulated and slightly hooked form of the anterior angles of the fore wings. The wings are generally of 
brightish yellow or ferruginous tone, and slope downwards on either side, like a steep roof, when at rest. The 
Caterpillars are short, rather thick, attenuated at the head, and having a horny plate on the first segment. They 
feed on the buds and catkins of trees, when young, but afterwards are said to prefer low-growing plants. There are 
five species. 
Xanthia Flavago (the Pink-barred Sallow, No. 1) exhibits in a marked degree the yellow-toned wings which 
distinguish most of the species; the bars and marks, as indicated in the popular name, being of a rich pinkish tone. 
The Caterpillar (No. 2) feeds on the Lime and Sallow in the spring, and has been found also on Plantain, probably 
when in a more advanced stage, as characteristic of the habits of the larvee of nearly the entire genus. The Moth 
does not appear till September and October. It is not rare, being found in most of the woods "yound London, 
often fluttering over Ivy blossoms. It is also found in the north, as far as Birkenhead, and even Edinburgh ; many 
intermediate localities are also recorded as places where it is tolerably common. 
The other species are all distinguished by names having reference to the yellow, orange, or ferruginous 
tone of their general colouring—namely, X. Cerago (the Sallow), X. Gilvago (the Dusky-lemon Sallow), X. Acerago 
(the Barred Sallow), X. Citrago (the Orange Sallow). 
Tue genus Judia, in British collections, contains at present but one species, formerly grouped with the 
Xanthie. Having been deemed sufficiently distinct to form the type of a separate genus, Mr. H. Stephens, in detaching 
the species in question, called the new genus Xantholeuca ; but the name Jodia, dating as early as 1816, has since been 
preferred. This genus is mainly distinguished by the elongated palpi, having the appearance of a beak ; the abdomen 
is much flattened, and the fore wings are acute at the tip. The larva is not attenuated towards the head, and has a 
slight hump on the twelfth segment. The pupa is subterranean. 
Jodiu Croceago (the Orange Upperwing, No. 3) is a variable insect in colour, some specimens being much 
paler, and others darker, with more distinct markings, than the one in my figure. The Caterpillar (No. 4) feeds on 
Oak. The Moth appears in autumn, and sometimes survives the winter. It is considered rather rare, but has been
