middle, in one pale cT obsolete ; costal area more or less 

 suffused with dark brown on posterior half, sometimes marked 

 with ochreous-whitish and blackish streaks ; dorsum some- 

 times suffused with dark fuscous, in one o* a broad dark 

 fuscous streak along dorsum, contrasted with pale whitish- 

 ochreous remainder of wing ; sometimes two or three blackish 

 dots towards tcrmen below middle : cilia whitish-ochreous or 

 pale ochreous, above apex brown, beneath tornus with a 

 blackish spot. Hindwings dark fuscous ; cilia greyish, with 

 dark fuscous subbasal shade.

Antennae in cf ciliated. Palpi moderate or long, porrected, 

 second joint with projecting scales above and beneath, ter- 

 minal short. Thorax without crest. Forewings with 7 

 separate, to termen. Hindwings with 3, 4, 5 closely approxi- 

 mated at base, 6 and 7 stalked. 



This genus, formerly regarded as represented throughout 

 most of the world by one very variable species, is now 

 recognised as consisting of a considerable number of closely 

 allied and generally similar species. These would often be 

 very difficult to separate by the markings of forewings ; but 

 the shape of the forewings, the length of the palpi (usually 

 somewhat longer in 9 than in cf ), and sometimes the colour 

 of hindwings give reliable characters, and the species so 

 defined are found to be superficially and geographically 

 consistent. Probably most or all are attached to rushes 

 (Juncus) or allied plants. Collectors have usually neglected
