NATHAN BANKS. 35 



narrow; costal area moderately broad at base; median bent toward cubitus at 

 connecting veinlet; a veinlet connecting median to radius near base of first 

 radial sector; last veinlet of inner gradate series is beyond preceding one; in 

 hindwings the radial sector forks before forking of median. Expanse 18 mm. 



Type from top of Las Vegas Range, 11,000 feet. New Mexico 

 (Cockerell), and the type oi H. eaudelli, which I consider identical, 

 is from London Hill Mine, Bear Lake, British Columbia, 7,000 

 feet, July 29th. 



Henierobius coiijiinctns Fitch. — Head blackish, a pale spot on the 

 labrum and one above antenna?; latter pale; thorax pale, a brown stripe each 

 side; legs pale; the abdomen fuscous. Wings with pale venation, dotted with 

 brown, these dots often surrounded by small clouds, those on the veinlets con- 

 necting median to anal form a large and prominent spot, and on the gradate 

 veinlets, which are brown, they form a continuous band, border of wings rather 

 obscure, and with alternating dark and pale dots, pterostigma hardly distinct ; 

 hindwings not maiked, the costal and some of the gradate veinlets brown. 

 Wings not very broad, tip almost pointed, costal area narrow toward base; me- 

 dian distinctly bent at connecting veinlet toward cubitus, a veinlet connecting 

 median to radius close to base of the first sector; three sectors, upper branch of 

 the third forked twice before outer series of gradate veinlets, lower branch sim- 

 ple, last gradate veinlet of inner series is below or basad of previous one. Ex- 

 panse 16-18 mm. 



Specimens from Mt. Washington and Franconia, New Hamp- 

 shire (Slosson) ; Fitch's specimens from central New York, May ; 

 and Currie's glacialis, which is apparently the same (the specimen 

 being very poor), is from Kokanee Mountain, British Columbia, 

 9,000 feet, August 10th. It is taken on or near pine trees. The 

 type is in the Hagen collection. 



Hemerobins iievadensiK Banks.— Head pale yellowish, a brown dot 

 between antennae, the latter pale yellow, darker at tips. Thorax dark brown, 

 with a broad median yellow stripe; abdomen dark brown, nearly black; legs 

 pale yellow. Wings hyaline, the veins mostly pale, the radial sectors and some 

 others dotted with brown. Around the margin are brown spots alternating 

 with whitish ones; the gradate series are rather heavily maiked with brown, 

 and the veinlets connecting median, cubitus and anal near base are also brown. 

 In the hindwings the venation is pale, except around the margin, where it is 

 brown. The forewings are moderately long, the costal area rather narrow af 

 base, the lower branch of the median is not bent toward the cubitus, so that the 

 connecting veinlet is as long as that connecting cubitus to anal. Basal cross- 

 vein connecting median to radius ends near origin of first radial sector. In the 

 hindwings the first fork of radial sector is plainly before the forking of median 

 vein. Expanse 15 mm. 



One specimen, Ormsby County, Nevada, July (Baker).
