This species measures 1+ inch in the expansion of the fore wings, which are of a ‘greyish colour, tinged with 
lilac, with four. pale streaks, the first and second obliquely transverse, the third abbreviated in front and bent, 
and the fourth interrupted in the middle, the anterior portion running through the large, chocolate, apical patch, 
the extremity of which is tinged with lilac, and marked next the stripe with three orange dots; beneath the 
chocolate patch is a black dot, preceded by a row of smaller ones. The hind wings are brown. 
The caterpillar is grey, having a lateral row of fulvous spots, two black stripes down the back with fulvous 
dots ; the fourth and anal segment with a large chesnut tubercle. It feeds on willows and poplars, in June and 
October, and the moth appears in May and July. It is extremely rare in England, no other specimens being 
recorded except those in the British Museum, which were captured near Salisbury by the late Mr. Spratt.

This species measures from 11+ to 14 inch in the expanse of its fore wings, which are of a reddish grey colour, 
with four nearly straight, whitish streaks, and a large apical patch entirely of a testaceous brown, or shining, 
reddish fawn-colour, in which is an obscure row of five brown dots. The hind wings are ashy-grey coloured. 
The caterpillar is pilose, ashy-coloured, with four rows of reddish spots. It is found in the autumn on 
willows and poplar-trees, the moth appearing at the end of April or in May; also (according to Boisduval) in 
July. It occurs, but by no means abundantly, in the neighbourhood of London, and other parts of the south of 
England, and has been found near Coleshill by the Rev. W. T. Bree. 
The remainder of the species represented in this plate (13), and the majority of those upon the following 
plate, constitute (notwithstanding the singular diversity of the caterpillars) a natural group, which Ochsenheimer 
retained as a separate and single genus, under the name of Notodonta, a name derived from the Greek, having 
reference to the prominent lobe of scales upon the hind margin of the fore wings, and which, when the insect is 
at rest, is raised over the back ; whence the English name of Prominent moths, given by collectors to these 
insects, which have been subdivided by Mr. Stephens into a number of genera, several of which have been sunk 
by Curtis and Boisduval. 


NOTODONTA (vars rypica, OcHsENHEIMER), STEPHENS. 

As restricted by Mr. Stephens, this group comprises those species which have the fore wings moderately long 
and obtuse at the tips, with a single hind lobe, and the outer margin somewhat denticulated ; the thorax not 
crested ; the antenne only pectinated in the males, being simple in the females. The caterpillars are smooth 
(without hairs), with the back tubercled, being furnished with two imperfect anal feet. They generally rest

with the extremity of the body elevated, in the same manner as Stauropus and Cerura.
