Hagen (in " Hemerobidarum Synopsis Synonymica ") 

 refers this to lutescens of Fabricius, but it now appears 

 to me impossible that the latter insect can be equivalent 

 to our concinnus; ''magnitudo et statura prgecedentium 

 (our 8isyra fuscata) , alae omnes albae punctis strigisque 

 fere indistinctis, fuscis." That Fabricius could have 

 compared the largest European species with Sisyrafuscata 

 in point of size is impossible, and I consider his lutescens 

 as far more likely to be identical with our micans. Bur- 

 meister's lutescens is, no doubt, micans ; that of Rambur 

 is probably liumuli, as is also that of Zetterstedt. 



Genus VI. Megalomus, Rambur. 



General characters similar to those of Hemerohius ; 

 the anterior loings broader and more strongly rounded at 

 the apex ; the costal area broader at the base ; the sectors 

 more numerous ; and the margins and veins strongly 

 ciliated. In the posterior wings the costal margin at the 

 extreme base is elevated into a sort of broad tooth which 

 carries a tuft of long hairs (PI. X. fig. 11) . 



Rambur includes Drepanepteryx phalcenoides in Mega- 

 lomus, but that insect has sufficiently trenchant characters 

 to form a separate genus. 



1. Megalomus hirtus, Linne. 



Hemerohius hirtus, Linn. Faun. Suec. 382 (1761), Syst. 

 Nat. i. 912; and other authors. H. fimhriatus. Curt. 

 Brit. Ent. pi. ccii (1828) ; Steph. 111. vi. 113. Megalo- 

 mus tortricoides , Ramb. Nevrop. 419 (1842). 



Fuscous, strongly pilose. 



Antennce fuscous, the two basal joints ochreous. 



Prothorax with an ochreous spot on each side. Mesa- 

 thorax veined with ochreous in such a manner as to form 

 two rings, filled in with a pupillate spot of the dark 

 ground colour. 



Abdomen dark blackish fuscous, marked with ochreous 

 at the base. 



Legs pale ochreous ; femora fuscescent ; anterior and 

 intermediate tibiae fuscescent at the apex, and slightly 

 so at the base ; posterior tibige fuscescent in the basal 

 third, otherwise ochreous ; the terminal joint of all the 

 tarsi fuscescent.
