formiug the inuer edge of a conspicuous bright white stripe, 

 wtich is throughout intersected by a brown line following 

 every indentation, this white stripe being the one conspicuous 

 marking of the wing ; bej'ond it from the costa is a slender, 

 indented, perpendicular, short white streak, the commence- 

 ment of the subterminal line, which otherwise is only per- 

 ceptible in faint isolated dots and angles ; extreme hind 

 margin dotted witli black ; cilia brown, faintly dashed with 

 cloudy white. Hind wings elongated, but rather broad, 

 rounded behind ; glossy smoky-brown with an obscure but 

 broad whitish central transverse baud; cilia dull white 

 dashed with smoky-brown. Female very similar. 



Underside of the fore wings smoky-brown ; the white 

 rivulet stripe faintly visible, much more so on the costa, 

 where it is preceded by a black bar ; a triangular whitish 

 spot runs into the apex. Hind wings smoky-brown, with 

 the central whitish band distinct, and edged on each side 

 with dark brown ; hind marginal region clouded with whitish- 

 brown. Body yellow-brown ; legs umbreous. 



Variable in size ; usuall\" very constant in colour and 

 markings, yet there is a little vai-iation in the breadth and 

 distinctness of the rivulet stri])e. Mr. F. N. Pierce possesses 

 a specimen in which it is remarkably broad ; on the other 

 hand, a local form is reported from the North of Ireland, by 

 Mr. Kane, in which the general colouring is of a more 

 smoky-brown and the rivulet is almost or quite obsolete. 



On the wing in June and July, sometimes even at the end 

 of May in the extreme south. Specimens of a partial second 

 generation have been reared in Devon in August. 



Lakva not more than half an inch long ; of about equal 

 thickness to the tenth segment, whence it tapers a little to 

 the anal extremity ; head rather broad, yet a little narrower 

 than the second segment, glossy black or black-brown, the 

 lobes well defined on the crown by a margin of pale skin, 

 from a blackish-brown shining ])late on the second segment;
