PHRYGANIUE. LIMNKIHILUS. 211 



nervures, and a curved series of pale streaks beyond them ; inferior (posterior) 

 wings fuscous-ochreous, very pale at the base." — Curtis, I. c. 



Found rarely near London ; also in the Isle of Wight, Devon- 

 shire, and Dorsetshire. 



Gekus XXXI.— LIMNEPHILUS, Leach. 



AntenncE slender, setaceous, somewhat approximating and slightly pubescent, 

 especially in the males, shorter than the wings : palpi pubescent ; maxillary 

 5-jointed, pilose at the base, the 4th joint shorter than the 5th, which is 

 slightly elongated and a little attenuated ; labial 3-articulate, with the two 

 basal joints pilose : /leat/ small, transverse : ej/e^ prominent, globose : thorax 

 small, subovate-convex : wings deflexed during repose ; anterior long and 

 narrow, the costa not dilated towards the apex, the hinder margin obliquely 

 truncate, and sometimes deeply excised ; posterior ample, thin, and much 

 folded when at rest : abdomen slightly compressed in the males, stouter and 

 rather longer in the females : legs moderate: coxce long and setose: femora 

 slender, unarmed; tibise and tarsi armed with short spines, the former with a 

 small pair of spurs at the apex, and the hinder pair with two others below 

 the middle. Larva with the head and three anterior segments horny, 4th 

 segment with two or three tubercles, the terminal one with two claws ; legs 

 long : inhabits a case composed of sand, pebbles, pieces of wood, bones, &c. 

 in which the pupa is also formed. 



Known from the allied genera by having the hinder margin of the 

 anterior wings more or less truncate, and in some instances deeply 

 emarginate : the wings are in general narrower than in the other 

 Phryganidae, and the nervures somewhat indistinct : there is great 

 similarity among the species, which, however, form several very 

 distinct groups, and the last species offers many points of distinction : 

 the species of the 1st section may probably form a distinct genus, as 

 indicated in the 2nd edition of my Nomenclature.
