TRIFID/E. 35-, 



brown, shading- gradually to dark smoky-brown toward the 

 hind margin ; nervures rather darker, and a darker transverse 

 stripe lies across the middle of the wing ; cilia dusky-white, 

 intersected by a pale brown line, and strongly dashed with 

 clear white. Female with simple antenna3 and stouter body, 

 otherwise quite similar. 



Underside of the fore wings pale smoky-brown to beyond 

 the reniform stigma, which is smoky-black ; beyond this 

 much tinged with glossy purple ; hind wings very similar, 

 but with a smok}--black central spot, and the purple clouding 

 edged inwardly by a central cloudy-brown stripe. Body and 

 legs dull brown with a purple tinge ; tibite black, barred with 

 pale yellow. 



There is local variation in the colouring of this species, 

 specimens from the east of Scotland having the chocolate- 

 brown band and clouding less bright and more shaded with 

 slate-grey. In the collection of the late Mr. H. Doubleday, 

 at Bethnal Green, are specimens (unfortunately not labelled) 

 which show scarcely any of the red-brown colouring, their 

 ground colour being greyish-white, the clouding darker grey, 

 and the central band olive-brown. Occasionally the space 

 around the reniform stigma is conspicuously pale, forming 

 a large rounded grey section scooped out of the broad red- 

 brown band. On the other hand, a specimen in the collection 

 of Mr. W. H. B. Fletcher is banded with very rich dark 

 brown; while others have the central band broken up by 

 white clouds. 



On the wing at the end of May and in June ; sometimes 

 in July further north. 



Larva cylindrical, twelfth segment slightly raised, 

 thirteenth sloping off to the anal prolegs, which project 

 backward ; head rounded, highly polished, shining dark 

 hazel-brown ; body velvety dark brown with a purple shade 

 on the sides, or else with an ochreous tint on the same portion, 

 and irrorated with pale purple ; dorsal line threadlike, faintly
