rust-red subdorsal lines, which run parallel from the base of the antennæ to the last segment; another similar line, united along the inner margin of the wing, passes over two spiracles, and then runs parallel with the subdorsal lines.... The antennæ and wings are faintly outlined with dusky brown. In general appearance and colouring the pupa closely resembles a piece of dead withered grass." A female butterfly emerged on May 20, the transformation from egg to perfect insect thus occupying about eleven months. This local butterfly is on the wing in June; sometimes it is seen in the latter part of May, and, more rarely perhaps, in July. This species appears to have been first noticed as an inhabitant of Britain in 1798, in which year specimens were taken in Clapham Park Wood, Bedfordshire, by Dr. Abbott, who, four years later, also reported the butterfly from White Wood, Gamlingay, Cambridgeshire. In 1823 it was found to occur at Castor Hanglands, near Peterborough; and in 1841 Doubleday met with it, in large numbers, in Monk's Wood, Huntingdonshire. Among other localities from which it has been reported are Ropsley Wood, near Grantham, Notts, and Wychwood Forest, Oxfordshire. In its special localities, which, at the present time, are chiefly the larger woods in Lincolnshire, Northamptonshire, and Buckinghamshire, it frequents the flowers of ground ivy (_Nepeta glechoma_) and of the bugle (_Ajuga reptans_). Abroad it is locally common in various parts of Central Europe; also occurs in Finland, Central and Northern Russia, Dalmatia, Piedmont, and in Labrador, and other parts of North America.
