Hemerobius glacialis, n. sp. 



Alar expanse 15.5 mm. Body above and below obscure fuscous or pice- 

 ous; basal half of antennae, vertex, a posterior central spot and posterior 

 lateral angles of pronotum, a broad longitudinal median band on meso- 

 and metanotum, and the legs principally, pale. Anterior wings rather 

 broad their width two-fifths of their length their tips? (torn off), 

 basal half of costal area rather broad; hyaline, tinged with smoky and 

 marked with fuscous ; veins pale, with scattered brown spots principally 

 where crossed by the wing markings; these wing markings consist of an 

 irregular, more or less interrupted band on each gradate series, numerous 

 short, irregular spots (sometimes tending to form bands) along the longi 

 tudinal veins, some larger spots at forking of median and along cubitus, a 

 large spot on subpterostigmal radial cross vein, and some transverse 

 spots in costal area, these spots pale in basal portion; apex and hind 

 margin of wing tinged with smoky; pterostigma indistinct; a longitudi 

 nal pale line bisects costal area at bases of intercostal forks ; posterior 

 fork of median bent toward cubitus, making the inner veinlet connecting 

 with cubitus shorter than the outer; radio-median cross vein situated at 

 the base of fork of median and joining radius at origin of first sector; 

 forking of median almost directly beneath origin of first sector; three 

 sectors, anterior branch of the third forked before inner gradate series and 

 subpterostigmal radial cross vein, posterior branch simple; five gradate 

 veins in inner series, the last before the next to the last, six in outer series. 

 Posterior wings hyaline, with a faint smoky tinge, most of the veins 

 dark except at base; first fork of radial sector plainly before forking of 

 median. 



Kokanee Mountain, altitude 9,000 feet, 10 August, collected 

 upon snow on glacier ; one specimen. 



Type. No. 7899, U. S. National Museum. 



This Hemerobiid bears some resemblance to H. kokanceanus 

 and If. caudelli. It seems to be more closely related to the lat 

 ter, however, since it substantially agrees with that species in the 

 position of the radio-median cross vein and the relative position 

 of the forking of median vein and origin of first radial sector ; like 

 that species, also, it is pale on the vertex and on the meso- and 

 metanotum. It differs from H. caudelli in that the last gradate 

 vein of inner series is before the next to the last, while the ante 

 rior branch of third radial sector is forked before 4 the inner gradate 

 series and subpterostigmal radial cross vein ; the wing markings, 

 also, are smaller and less extended. 



Hemerobius kootenayensis, n. sp. 



Alar expanse u mm. Body above and below, including legs and anten 

 nae, pale yellowish, the latter somewhat darker apically ; a stripe below 

 each eye and the apical joints of palpi piceous ; sides efface tinged with red-
