126 THE GENERA OF BRITISH MOTHS. 
may be distinguished by the broad and abruptly-terminating dark border, spotted with white, which ornaments 
the hind wings. 
The genus Paraponyx. The insects assigned to this genus have been separated from the Hydrocampe 
chiefly on account of the singular structure of the Caterpillars, which have, in addition to the usual spiracles, a 
breathing apparatus composed of branchiw, analogous to those of the larve of the Lesser Dragon-fly and other 
aquatic larve. ; 
Paraponyx Stratiotata (the Ringed China-mark, No, 5). This pretty species is as common as the preceding. 
The Caterpillar is described by M. Guénée as being of a whitish-green colour, with a darker line down the back, 
and the head brown, and having minute feather-like appendages connected with the organs of respiration. It 
feeds upon the beautiful plant Stratiotes aloides, and the Moth appears in June and July, being common in 
marshy places, but rather more local than the other China-marks. 
The next, and fourth, Sub-Family, of the Pyralide is that of the Botydi, which comprises most of that pretty 
group of small moths popularly known as the Pearls. The antenne are filiform, the abdomen generally long and 
slender. The wings are also of narrow proportions, forming a long deflexed triangle when in repose, and they 
have generally a pearly gloss, which has suggested the popular name of the group. The Caterpillars are slender, 
sixteen-footed, and form the chrysalis in a cocoon of dried leaves or moss webbed together. 
The genus Phyctenia. ‘The single British insect assigned to this genus forms a link between the true China- 
marks and the Pearls. The antenne are simple in both sexes. The palpi are long and horizontal. The wings are 
dark-coloured, with pale blotches. The Caterpillar is not aquatic, and forms a compact cocoon, in which it 
undergoes the change to the chrysalis state. 
Phyctenia Sambucalis (the Garden China-mark, No. 6). This is a very pretty species. The Caterpillar 
(No. 7) feeds upon the foliage of the Elder, in September and October, and the Moth appears in the following 
June, being very common in gardens. 
The genus Eurrhypara. The typical insects of this genus have the body rather long, and belted with black. 
The palpi are short, the antenne long and slender. The wings are moderately long, and are generally white, 
strongly marked with dark brown or blatk, from which they haye been termed the Magpies. The Caterpillar is 
sixteen-footed, and the chrysalis is produced in a rolled leaf. 
Eurrhypara Urticata (the Small Magpie, No. 8). The Caterpillar (No. 9) of this conspicuous insect is a 
Nettle feeder, in September. It remains in the chrysalis state through the winter, and the perfect insect appears 
in the following June. It is abundant everywhere in lanes and gardens. 
The genus Zbulea. The antenne of the insects assigned to this genus are simple in both sexes. The 
abdomen is slender. The wings are rather broad, and the tips of the anterior pair rather pointed. The Caterpillars 
are short, and attenuated at each end. The Chrysalides are enclosed in a cocoon among leaves. There are two 
British species in the system I am following, but some authors also assign the species last described to this genus. 
Ebulea Verbascalis (the Rusty China-mark, No. 10) is not a common species ; Darenth Wood, Ranworth, 
Chatham, and Charlton, are cited as localities in which it has been recently taken ; and though it is extremely 
local, it is sometimes abundant in its favourite haunts. The Caterpillar is unknown. 
The other species of Ebulew is E. crocealis, which closely resembles the preceding in form and general 
tone of colour; but the front wings are of nearly unvaried pale ochreous brown, without the bands and markings 
of Verbascalis, and the hind wings are very pale ochre, with only a faint band near the border. 
The genus Nascia. In this genus the antenne are slender and filiform, but slightly pubescent in the 
males. The palpi are united, like a beak, and drooping. The fore wings have the apex slightly hooked. There 
is but one British species. 
Nascia cilialis (the Orange Cloud, No. 11). The Caterpillar of this species is unknown, and the Moth is 
very local and rare. It was first taken near Cambridge ; and Yaxley, and Wicken Fen are localities in which it 
has been most lately observed. 
The genus Udea. The British species which is now placed in this genus, in the system I am following, was 
located by Mr. Stephens in the genus Margaritia, and is now placed by some writers in the genus Scopula, With
