TOHTRICINA. 75 



above the anal angle. From the centre of the costa to within the 

 anal angle proceeds an undefined and indistinct fascia, made up of 

 pale ferruginous, brown, and leaden-coloured markings, the dorsal 

 portion being spotted irregularly with black. The ocelloid patch is 

 present, but very undefined ; it is of a cream-coloured ground, with 

 two rose-pink clouds and minute spots between them ; the dorsal 

 margin speckled with brown. Apical scales mixed, black and white. 

 Cilia dull, mottled iron-grey and pale ferruginous brown, both be- 

 coming delicate rose-pink at the anal angle. Posterior wings shining, 

 clothed with coarse fuscous scales on a pearly ground. Marginal 

 scales fuscous, with pale bases. Cilia shining, pale straw-colour. 

 Abdomen pale fuscous, the caudal tuft slightly ochreous. $ Exp. 

 al. 8-1-9 lin. 



A comparatively new insect to the British list, being first 

 recorded by Mr. Stainton in the ( Zoologist' for 1848, p. 1988. 

 Variable in size and colour ; some specimens not so large as 

 Sp. Irimaculana, whilst others attain to dimensions as large, or 

 even larger than Sp. Roborana. In general appearance it is like 

 Sp. trimaculana, but the cream and pink ground-colour of the 

 anterior wings at once distinguishes it. 



The imago appears in July and August among Rosa spino- 

 sissima not uncommonly. It seems to affect the coast, having 

 been taken at the Isle of Portland, at New Brighton in Cheshire, 

 and on the coast of Cumberland j it is likewise taken inland at 

 Riddlesdown, Sanderstead, near Stoat's-nest, Boxley, near Maid- 

 stone, near Guildford, &c. 



Genus VII. LITHOGRAPHIA, STEPHENS. 



Palpi longer than the head, clothed with long hairy scales at the 

 sides, beneath, and at the apex ; basal joint stout, drooping, pyri- 

 form, truncate ; apical as long as the basal, slender, obovate ; middle 

 stout, curved, ascending, thickest beyond the centre, four times as 

 long as the apical. Maxilla3 as long as the palpi. Thorax stout, 

 subglobose. Anterior wings : length equals three times the width ; 

 costa in the c? folded to the middle, arcuated ; apex obtuse ; apical 

 margin concave ; dorsal margin slightly rounded ; the discoidal cell 

 nearly isometric, extending three -fifths of the length of the wing ; 

 the three subcostal nervures equidistant ; the costal vein not reach- 

 ing beyond the fold. Posterior wings : apex obtuse, concave at the 

 apical margin ; the median vein furcate at the apex. Abdomen 

 stout in both sexes ; tufted in the c? . 



The same cause has operated in restricting the extent of this 

 genus as in the preceding one, the remaining number of British
