In selecting the specimens for this and a few of the succeeding plates, I have not strictly followed the exact 
order of the system which I have adopted, a table of which will, however, be found at page 16.. At the close 
of the Arctiidae, I shall also append a list, showing the order in which the collection of native Lepidoptera in 
the British Museum are at present arranged, up to the end of that family. 
The genera illustrated in the present Plate are all of the recently formed family, Notodontida. 
The genus Stauropus. In this genus the males haye the antenne pectinated nearly to the tips. The 
antenne of the females are simple. 
No. 1, Stawropus Fagi, is popularly known as the Lobster-Moth, from the singular form of the Caterpillar. 
The aspect of the Moth, however, presents none of those anomalous characters which one would be led to 
expect from the very unusual form of the larya. This insect is rare. The Caterpillar appears in the autumn, and 
the perfect Moth in the following July. There is no other British species in the genus Stawropus. Exeter, 
Blandford, Lewes, Dursley and other places, are cited as localities where S. Fagi has been recently captured. 
The genus Notodonta has the antenne pectinated in the males, and simple in the females. It contains 
three well-marked species, 
No. 3, Notodonta Zic Zac (the Pebble Prominent) is the handsomest of the genus. The Caterpillar 
(No. 4) is remarkable, like that of VN. Dromedarius, (which has received its specific name in consequence), for 
the singular humps upon the fifth and sixth segments. It is not an uncommon species, and appears in 
May and August. The Caterpillar feeds on the Poplar and Willow, and may be found both in June and 
September. There are two other species. 
1. N. Dromedarius (the Tron Prominent) is rather larger, and not distinguished by the mass of deeper 
markings at the tips of the fore-wings, like that species. The ground colour is a dull deep brown, traversed 
by two narrow wayed bands of a warm ochreous tone, with an irregular crescent-like mark of the same colour 
between them, as also some other ochreous spots close to the shoulder. The hind-wings are of a full dusky 
slate colour, traversed by two faint irregular bands of a lighter and warmer tone. The Caterpillar is green ; 
a broad mark on the back extending only along the first three segments, and the legs are all rosy pink. 
The humps, from which the species takes its name, are yellowish. It is found on Oak, Poplar, Hazel, ete., in 
September, and the Moth appears in June and August. It was formerly thought rare, but is now frequently 
found by careful collectors. 
2. N. Lritophus (the Dark Iron Prominent) is much like the preceding species, except that it is smaller, 
and the ground colour of the fore wings is rather of a slate colour than brown; the hind wings being dull buff, 
grayish at the edge, and with a gloudy gray band near the middle. The larva is dark green, with humps, and 
a reddish line from the head to the fifth segment. This species is very rare.
