The moth flies in August and September, and at night will visit the sugar patch and also heather blossom. It has but few fixed localities in England, and these are chiefly in Nottinghamshire (Sherwood Forest), and Yorkshire (woods near Doncaster, Huddersfield, and Sheffield). There are, however, records of its occurrence in the south of England. Stainton obtained one at Lewisham in 1846, and Barrett notes one at Highgate in 1870. One or two specimens have occurred in Essex, Somersetshire, and Gloucestershire. From its headquarters in Notts and Yorks. it seems to find its way occasionally into some of the adjoining and other counties. Forsythe states that he bred the moth from larvae obtained from oak at Methop, Lancs., and it has been reared from a caterpillar taken in North Shropshire. It has occurred on Cannock Chase, Staffs., and rarely in Worcestershire. From Porritt's _List of the Lepidoptera of Yorkshire_ we learn that the occurrence of this species in Yorkshire was not noted until 1880 (Doncaster), but it seems to have since extended its range in the county, as in 1900 it was found in the Huddersfield district, and a few specimens occurred near York in 1903. As stated, it has been bred at Methop, Lancs., and, according to Barrett, it is not scarce in Cumberland. Southwards from its Yorkshire and Nottinghamshire headquarters it has been noted, more or less rarely, in Staffordshire, Shropshire, Worcestershire, Gloucestershire, and Somerset; and on the east side in Lincoln, Norfolk, Essex, and Kent. In Scotland it appears to be not uncommon in Moray, and it is occasionally recorded from Inverness and Perth. The range abroad extends to Amurland and to North America. [Illustration] 2 Pl. 4. 1.

Of this species (Plate 4, Figs. 2 and 3) there are two groups of forms--plain and variegated. To the first belongs the type with reddish-brown fore wings; a dark modification of this form is ab. _nigrescens_, Tutt, which has the fore wings blackish red; a brighter red form is ab. _rufa_, Tutt. Of the variegated sections three forms have been named, but the most important of these is var. _congener_, Hubn., with the inner and the outer marginal areas of the reddish fore wings ochreous; two other modifications have the ground colour redder or dark purplish inclining to blackish.
