Rhyacophila brunnea Banks, 1911, p. 252. 
Lectotype, female . — Beulah, New Mexico, July 16. No. 
11735. 
There is a series of males and females in the M. C. Z. from 
Cultus Lake, B. C., the females of which appear exactly like 
the lectotype of brunnea in color and external genitalia. A 
male of this series has been selected as the allotype. It be- 
longs to the acropedes group, fig. 4, but is readily distin- 
guished by details of the genitalia. 
Allotype , male. — Cultus Lake, British Columbia : May 18, 
1933, W. E. Ricker. 
Rhyacophila Carolina Banks, 1911, p. 353, fig. 31. 
Lectotype , male. — Black Mountain, North Carolina, north 
fork Swannanoa River, May. No. 11727. Lectoallotype, 
female. — Same data. 
In addition to those in the original description, illustra- 
tions of the genitalia have been given by Betten (1934, pi. 5, 
figs. 4-7) . 
Rhyacophila coloradensis Banks, 1905b, p. 10. 
Lectotype, male . — Fort Collins, Colorado. No. 11728. 
This species is close to bifila Banks, but is readily distin- 
guished by details of the genitalia, fig. 5. 
Rhyacophila fairchildi Banks, 1930a, p. 130, figs. 4, 7. 
Lectotype, male. — Baddeck, Cape Breton Island, Nova 
Scotia, September 4, 1928. No. 16237. Lectoallotype, fe- 
male. — Same data. 
The genitalia of the lectotype agree perfectly with the 
illustrations of glaberrima Ulmer and with the genitalia of 
the type of andrea Betten. There seems little doubt, there- 
fore, that both fairchildi and andrea are synonyms of 
Ulmer’s species, originally described from Georgia. 
Rhyacophila formosa Banks, 1911, p. 353. 
Lectotype, female. — Delaware Water Gap, New Jersey. 
No. 11078. 
To date no male has been associated with this form, draw- 
ings of which are given by Milne (1936) . 
Rhyacophila grandis Banks, 1911, p. 350, fig. 27. 
Lectotype, male. — Bon Accord, British Columbia, June 14. 
No. 11737. Lectoallotype, female. — Same data, but June 19.
