Limnephilus multifarius Walk.! Catal. 32,43. Phryganea variegata Barn- 

 ston, Mss. Limnephilus perforates Walk. Catal. 33, 46. (In part.) 



Black, with pale hair, and longer pile, which is black ; antenna? 

 fuscous, annulated with testaceous; feet testaceous; anterior wings 

 fuscous, freckled with whitish ; thyridium and base of the apical 

 areoles spotted with white ; posterior wings cinereous. (From the 

 description of Walker.) 



Length to tip of wings 11 millim. Alar expanse 21 millim. 



Hab. St. Martin's Falls, Albany River, Hudson's Bay (Barn- 

 ston) ; L. perforates Walk, (from St. Martin's Falls), certainly is 

 the same species ; a very much mutilated specimen from Arctic 

 America (Mackenzie and Slave Rivers, Richardson) is different, 

 but indeterminable ; possibly the true L. nebulosus of Kirby. L. 

 despectus and L. multifarius are very closely allied ; are they dis- 

 tinct?
