1933 ] Trichoptera from the Appalachian Mountains 39 
head. Fore wing : Rs arising close to the base., with three 
branches (R2, R3, R4 + 5) ; M with two branches; Cut un- 
branched. 
$ Spurs 1, 4, 4 ; basal segment of antennae longer than 
that of male and less thickened ; venation similar to that of 
male, except that R4 + 5 is forked in both fore and hind 
wings. 
Genotype: Neuropsyche tibialis, n. sp.

Figures 3, 15, 16. 
$ Length of fore wing, 6-7 mm; vertex and frons light 
yellow; antennae light yellow; the basal segment covered 
with light yellow hairs ; maxillary palpi yellow, the ventral 
surface covered with long, brown hairs, and the dorsal sur- 
face, with whitish scales; labial palpi short, gray; thorax, 
legs, and abdomen light yellow. Fore wing : rather slender, 
nearly oval; R4 + 5 arising before the middle of wing; M 
dividing just beyond mid-wing. Hind wing: Rs branched 
as in fore wing ; M with two branches, arising before origin 
of R4 + 5; Cul unbranched. The wings are covered with 
flattened yellow hairs. 
$ Color and size as in male.

Neuropsyche is readily distinguished from the other 
North American genera of Sericostomatidse by the posses- 
sion of one tibial spur on the front legs, and four on the 
middle ones. This condition is not present in any other 
genera of our fauna, except the very aberrant Nosopus. I 
have placed the genus tentatively in the Lepidostominse, but 
its position is not at all certain.
