This species measures l\ incli in the expansion of the fore wings, which are of a greyish colour, tinged with 

 lihvc, witli four pale streaks, tliu first and second obh(iui'ly transverse, tlie third abbreviated in front and bent, 

 and the fourtli interrupted in the niiddk-, the anterior portion running through the large, chocolate, apical patch, 

 the extremity of which is tinged with lilac, and marked next tlic stripe with tliree orange dots ; beneath the 

 chocolate patch is a black dot, jireceded by a row i,{ smaller ones. The hind winos are brown. 



Tiie 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 Jlay and July. It is extremely rare in England, no other specimens beinc 

 recorded except those in the British Museum, which were captured near Salisbury by the late Mr. Spratt.

 Ilubncr, tab. 22, fig. 8'J. I Ilomht/x anachoreta, Espcr, 3, pi. 51, fig. 5. 



This species measures from l\ to 1.^, inch in the expanse of its fore wings, which are of a reddish grey colour, 

 with four nearly straight, whitish streaks, and a large a])ical 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 reddi.sh -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 tlic Rev. W. T. Bree. 



The remainder of the species represented in this ])late (13), and the mnjority of those upon the following 

 plate, constitute (notwithstanding the singular diversity of the caterpillars) a natural group, which Ochsenheiraer 

 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 (pars typioa, 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 antennas 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.
