BY NATHAN BANKS. 



Perla trivittafa nov. sp. — Length 14 mm. Head fulvous, with a large 

 trilobed lilack spot above, the upper lobe largest and coveiiug the ocelli, the lower 

 lobes extending toward the antennse ; below a black V-shaped spot with the apex 

 upward. Antennae and mouth-parts black; a black spot behind each eye; pro- 

 thorax slightly broader in front than behind, its angles rounded; fulvous, with 

 the side margins very broadly black, a narrow black median stripe, and the an- 

 terior margin narrowly black ; rest of thorax fulvous, mostly covered with lai'ge 

 black spots. Legs fuscous, with a pale yellowish elongate spot in front and behind 

 on all femora and on posterior tibiaj. Abdomen brown, a pale stripe on venter, 

 setie dark brown. Wings brownish, veins blackish, transversals at end of discal 

 cells nearly opposite, radial sector forked but once, upper fork much more than 

 twice as long as pedicel beyond transversals, three transversals between the 

 postcubiti. 



One male, Michigan Agricultural College, Michigan, C. F. Baker 

 collector. 



Chloroperia borealis nov. sp. — Length 14 mm. Yellowish ; head a little 

 broader than the prothorax, pale yellow, with a dark V-shaped mark connecting 

 the ocelli, two dark spots in front, and a small reddish tubercle each side; palpi 

 blackish, antennae fuscous, yellowish at base ; prothorax short, twice as wide as 

 long, a little broader in front than behind, the angles broadly rounded ; pale 

 yellow, the elevated margin blackish, each side a little rugulose and brownish; 

 rest of thorax and the abdomen brown. Legs brownish yellow, a transverse 

 black line at ends of femora; setae short, yellowish in middle, brownish at ends. 

 Wings greenish yellow, veins of anterior pair, except subcosta and radius, brown- 

 ish (in one wing there are two transversals beyond subcosta, but one is bent and 

 appears abnormal), transversals at end of discal cells are opposite each other, and 

 the upper fork of radial sector is more than twice as long as the pedicel beyond 

 these, there are five transversals between the cubiti. 



One female, Olympia, Wash., April (Trevor Kincaid). A male 

 from Ft. Collins, Colo., is smaller, 10 mm., and the radius is only 

 yellowish toward base, the transversals at end of discal cells are 

 slightly separated, and the forks of radial sector are not quite so 

 long, otherwise it is like the female. 



Cliloroperia pacifica nov. sp. — Length 10-12 mm. Yellowish, head a 

 little broader than prothorax, pale yellow, ocelli black. Antennae yellowish, 

 palpi brownish ; prothorax short, fully twice as wide as long, the anterior angles 

 moderately prominent, the posterior ones broadly rounded, the side margins dis- 

 tinctly black, within slightly rugulose. Legs pale yellow, with a black transver.se 

 line at ends of femora. Thorax yellowish, an oblique black suture on meta- and 

 mesothoracic pleura. Abdomen yellowish. Wings pale yellowish, all veins yel- 

 lowish, the transversals at end of discal cells are opjiosite to each other, the upper 

 fork of radial sector is one and one-half times as long as the pedicel beyond 

 transversals; there are four or five transversals between the cubiti. 



Three specimens, Skokomish River, Wash., May (T. Kincaid). 



C'hloroperla iinbecilla Say. 



A specimen from Olympia, Wash., agrees with eastern examples
