dish. Anterior wings rather broad their width slightly more than two- 

 fifths of their length their tips narrowly rounded, almost pointed, hind 

 margin rounded, basal half of costal space broad; hyaline, faintly tinged 

 with pale brownish, especially on veins on inner gradate series, at base 

 and apex of cubital cell, and along hind margin basally; veins pale 

 yellowish; posterior fork of median bent toward cubitus, making the in 

 ner veinlet connecting it with cubitus a little shorter than the outer; 

 radio-median cross vein situated at, or but slightly before, forking of me 

 dian (at forking of median in left wing, slightly before it in right wing, 

 in type specimen), and joining radius at origin of first sector; forking of 

 median almost directly beneath origin of first sector; three sectors (four 

 in right wing in type specimen, but the fourth forked only once before in 

 ner gradate series and subpterostigmal radial cross vein), anterior branch 

 of third (in left wing of this specimen) forked before inner gradate series 

 and subpterostigmal radial cross vein, posterior branch simple; five gra 

 date veins on inner series, the last very slightly before the next to the last, 

 the third from the last and next to the last particularly coinciding, seven 

 in outer series. Posterior wings hyaline, unmarked, the veins pale yel 

 lowish ; first fork of radial sector plainly before forking of median. 



Kalso, 17 June, one specimen.

This diminutive Hemerobius is allied, by venation, to H. cau- 

 delli and H. glacialis particularly to the latter. The faint, 

 pale brownish wing markings suggest that the type may be a 

 freshly emerged specimen and not fully colored. Its size and ap 

 pearance suggest//", canadensis Banks, but the latter is described 

 as having the " cubitus [median] not curving toward the postcu- 

 bitus [cubitus], the connecting veinlets each way about equal, 

 a connecting veinlet from cubitus [median] to radius before the 

 origin of the first sector ; four or Jive gradate vein- 



lets in outer series," etc. (The bracketed words and italics are 

 mine.)
