 than prothorax, ocelli rather large,. the ocellar triangle little broader than long, 

 the posterior ocelli about twice as close to the eyes as to each other, lateral 

 bosses about one half way from the posterior ocelli to antennal ridges. Pro-

Alloperla fidelis, sp. nov. 



Type.— M. C. Z. 10,823. Calif.: Tahoe, Great Alpine Creek,

 each other; lateral bosses rather nearer to anteimal ridges than to the posterior 

 ocelli. Pronotum more than twice as broad as long, sides rounded, and rather 

 narrowed behind. Female ventral plate with a distinct median emargination. 

 Radial sector nearer to the anastomosis than to tip; six or seven median, and

Expanse 22 mm. 



By marks of pronotum and absence of marks on the head it is allied 

 to A. pacified, which is smaller, and has the ventral plate entire.
