 stigmata pale or yellowish, the latter with a white dot at lower end; an outer row of dark dots on veins, 

 joined by a dark streak from apex; hindwing fuscous grey, paler basewards, the veins dark. Of almost 

 world-wide distribution, commonest in S. America. Occurs in Madeira, the Canaries, Spain, Portugal, France,

 favicolor. S. favicolor Bart: (25 k). Forewing pale olive brown ; veins concolorous, slightly defined b}' brown ; 



the intervals at termen with brown streaks; a small black dot at lower end of cell; an outer row of black 

 lutea. dots on veins, sometimes reduced to two only, on veins 2 and 5 ; hindwing fuscous whitish ; - - ab. lutea Tutt 

 rufa. is paler and yellowish; — in ab. rufa Tutt the head, thorax, and forewings are bright rufous; abdomen 

 argitlacea. and hindwing tinged with rufous; — argillacea Tutt has the forewing greyish luteous, the fringe pink; hindwing 

 senea. smoky; — ab. cenea Matheic is deep orange, the hindwing smoky; the veins darker and the fringe pale; — 

 obscura. obscura Matheic is cinnamon-brown with smoky clouding between the veins in places ; hindwing smoky; fringe 

 pallida, pale; -- pallida Matheic has the forewing very silky, pale creamy buff, the termen flushed with rosy; hind- 

 fasco-rosea. wing whitish grey; — lastly, fusco-rosea Matheic is rosy buff: the hindwing pale rosy: the veins conspicuously 

 dark brown ; close to the ab. rufa Tutt. At present found only in Britain, in the Essex Marshes. Larva pinkish 

 ochreous reticulated with darker; dorsal line pale, narrow, with darker edges: subdorsal greyish white; a 

 broader grey stripe above the spiracles and a pinkish ochreous one below them; on various grasses. 

 impura. S. impura Hbn. (= fuligosina Haw., punctina Haw) (25 f). Forewing ochreous, with a rufous tinge; 



veins, especiall}' the median, whiter, lined by fine brown streaks, which also appear in the interspaces: a
