TRfFID.E. 3 



hind inargiu very slightly sinuous; whitish-brown at tlu^ 

 base, shadin(>- oil to dark smoky-brown behind ; cilia white or 

 yellowish-white, intersected by a smoky-brown line. Female 

 much smaller, with narrower fore wings, smaller hind wings, 

 simple antennas, and the abdomen decidedly stout but taper- 

 ing off to a pointed anal tuft ; otherwise similar. 



Underside of the fore wings smoky-brown with a golden 

 gloss ; nervures rather thickened ; a black spot in the reni- 

 form stigma is surrounded by a smoky-white cloud ; hind 

 wings also smoky-brown, rather paler at the base ; central 

 spot dusky-black. Body and leg-tufts pale purplish-brown ; 

 legs umbreous, barred with pale yellow. 



Not usually very variable, except in the degree of white- 

 ness of the nervures, which sometimes is much obscured or 

 even obliterated. This in some instances extends to the 

 whiteness of the orbicular stigma. Such a specimen in 

 Dr. Mason's collection still bears Haworth's original label, 

 "Hibernica"; another, less uniformly dark, the label, 

 " lancea." There is a little difference also in the ground 

 colour, which sometimes is of a redder chocolate ; and in the 

 collection of Mr. Sydney Webb is a specimen of a pale grey, 

 but with the paler markings quite normal ; in that of Mr. 

 G. T. Porritt is one of a very rich purple-red, and another 

 extremely pale olive-brown. 



A very distinct variation in size occurs, the few specimens 

 met with in the Norfolk fens being always considerably larger 

 than the ordinary moor-frequenting form. 

 On the wing in August and September. 



Larva three-quarters of an inch long, moderately stout and 

 cylindrical except that the third and fourth segments are 

 thicker than the rest, and the larva tapers a little from thence 

 to each extremity ; head highly polished, pale reddish-brown ; 

 dorsal plate similar, margined in front with dark brown ; 

 anal plate similarly reddish-brown, flattened and depressed 

 in the middle but rather ridged behind ; mouth and ocelli
