several paler patches occupying the middle of the wing, followed by a waved and toothed, pale stripe. The 
apical portion of the wing is paler, with a row of small black submarginal dots, preceded on the costa by a 
luteous stripe ; the hind wings are brown, with an angulated, pale stripe running from the outer margin half- 
way across the middle of the wings. The female is more uniformly coloured on the fore wings. The caterpillar 
is rusty grey or fawn colour. The cocoon is described as closely woven, and more resembles silver paper than 
any other material, being, however, perfectly pliant to the touch. 
The moth is of rare occurrence ; having been found chiefly in the southern parts of England, in various 
localities. The most northerly recorded locality is near Worcester. The moth appears in June and in the early 

part of July, and the caterpillar in the autumn. It feeds on various forest-trees hazel, alder, sloe, &c.

This genus has the wings denticulated along the outer margin, but the posterior edge is not toothed; the 
thorax is crested with two elevated tufts at the sides ; the antenne in the males are thick, and obtusely dentated, 
and furnished with a double series of curved sete, which extend to the tip; the fore wings are elongate- 
triangular ; the abdomen is elongate, and terminated by an undivided tuft ; the fore feet are extended forwards in 
repose. The caterpillars are soft and hairy, sixteen-footed, and ornamented with interrupted black stripes on a 
pale ground ; the pupa state is passed beneath the surface of the ground.

This common but handsome species varies from rather more than 2 to nearly 3 inches in the expansion of 
its fore wings, which are of a silvery grey colour, but darker along the costa, with a slender transverse black 
line, preceded by a red one near the base of the wings, several dusky bars across the middle, and with a large, 
oval, cream-coloured apical patch, enclosing several small buff spots; edged within by a curved red line, 
preceded by a black one, which lines again occur near the anal angle of the fore wings ; the margin is varied with 
black, grey, and fulvous red. The hind wings are whitish, with a dusky mark near the anal margin. The 
thorax is buff, crested with dark brown at the sides and behind. The caterpillar is yellow, with black legs, and 
several rows of interrupted black stripes. It is found in the autumn on the oak, elm, and various other trees, 
living whilst young in society ; the moth appearing in June. The chrysalis is subterranean with two small

* The name Pygera (derived from the Greek miyn, nates, and aipw, porto), was given by Ochsenbeimer, evidently in allusion to the
