1933] Trichoptera from the Appalachian Mountains 41 
of comparison I have included here a drawing of the geni- 
talia of nig vita, which was originally described from the 
Black Mountains, N. Carolina (figure 11.) 
Rhyacophila glaberrima Ulmer 
Ulmer, 1907, Coll. Selys, 6, Trichoptera: 85; fig. 131, 132. 
This species has previously been known only by the male 
type, collected many years ago in Georgia 3 . I therefore 
take this opportunity to describe the female, several speci- 
mens of which were collected in 1930 : 
$ Color of body similar to that of $ , the head except 
frons dark brown ; frons yellowish ; hairs on vertex, at least 
those between the ocelli, yellowish brown; the warts be- 
tween the ocelli are very prominent and elongate-oval in 
shape ; the posterior warts are also long and oval. The fe- 
male herewith designated as allotype was collected by the 
writer between Blowing Rock and Linville, N. Carolina, at 
an altitude of 3-4000 feet, September 8, 1930. 
Forty additional specimens, of both sexes, were collected 
at the following localities : Bryson City, N. Carolina, Aug. 
26-27 ; Nantahala Gorge, Aug. 25 ; Andrews, Aug. 25 ; Mt. 
Mitchell, about 4000 ft., Sept. 4; Little Switzerland, Black 
Mountains, N. Carolina, Sept. ; and Newfound Gap, Smoky 
Mt., 5000-5200 ft., Tenn., Sept. 1-3. The insects resemble 
torva superficially, but the males are easily separated by 
the genital structure, as can be seen by comparing Ulmer’s 
figure of glaberrima with that of torva given here (figure 
7). The females can be distinguished by the hairs on the 
vertex, which are a very dark brown in torva but light 
brown or even yellow in glaberrima; and by the interocellar 
and posterior warts, which are rounded and flattened in 
torva, but oval and prominent in glaberrima. 
Rhyacophila Carolina Banks 
Two males found at Bryson City, N. Carolina, Aug. 28, 
and another on the road between Blowing Rock and Lin- 
ville, N. Carolina, Sept. 8. 
3 In the Genera Insectorum (1907) Ulmer erroneously gives the type 
locality as Massachusetts.
