well as the fourth ; the apical margin and cilia rather darker ; the stigmata are obsolete. The hind wings brown, 
with grey cilia, 
The variety named Approximans by Haworth has the basal striga obsolete, and the two outer strige 
approximating towards each other on the hind margin of the wing ; whilst the variety named Semifuscans by 
Haworth has the basal half of the fore wing rufous grey, and the apical half dark rufous brown, and the second 
striga thickened. 
The caterpillar is ashy grey, with pale stripes along the sides. It feeds on the plantain, and is full-grown in 
October. The moth occurs in various of the woods round London, and in Devonshire and Cumberland, &c., at 
the end of June and beginning of September ; it is not a very uncommon species.

This species measures rather more than 1} inch in the expanse of the fore wings, which are of a dark grey 
brown, with three straight transverse dark strige running across the wings, and margined with luteous, the basal 
one abbreviated ; there is also another very indistinct brown striga running across the middle of the wing through 
an obscure ear-shaped spot. The hind wings are pale brown, with the cilia and extremity of the body ochre- 
coloured. Found in June and July in various distant localities in the south of England, but certainly a rare 
species,

The curious species upon which recent French Lepidopterists have proposed this genus is at once distinguished 
by its caterpillar, which is entirely covered with silky hairs, and without oblique lateral lines ; the head is small ; 
it feeds on low plants ; the cocoon-is placed on the surface of the ground ; the body of the perfect insect is very 
much depressed in both sexes, terminating squarely, that of the female being but little narrowed. The antennz 
are rather thick and crenulated in the males ; the palpi not porrected before the frontal tuft. The fore wings are 
marked with numerous irregular spots on a bright yellow ground, clouded with reddish brown.
