1933 ] Trichoptera from the Appalachian Mountains 35 
Banks originally established this genus for latipennis , 
and later (1911) placed another species here (Carolina). 
Latipennis has previously been known only by the male 
type, but in the new material obtained in 1930, there are 
fifteen more specimens belonging to both sexes, which have 
enabled me to prepare a more complete description of the 
male and to describe the female for the first time. Carolina 
is known only by the three male types, all from Southern 
Pines, North Carolina, there being no additional specimens 
from the mountainous regions of that state. From my ex- 
amination of these types, which are in the Museum of Com- 
parative Zoology, I am convinced that Carolina does not be- 
long to Notiopsyche, but to an undescribed, aberrant genus, 
which I propose to call Oligopsyche. The characteristics of 
that genus will be considered below.

1905, Trans. Amer. Ent. Soc. 32: 11; pi. 2, fig. 20 (fore- 
wing), fig. 27 ( $ genitalia). 
$ Length of fore wing, 8 mm. Face grayish brown ; an- 
tennse mostly yellow-brown, the distal edge of each segment 
dark brown; basal segment dark brown and covered with 
brown scales and hairs; maxillary palpi movable, bearing 
yellow scales in the upper surface and dark brown hair and 
slender scales below; legs and thorax yellowish brown; 
wings uniformly gray; the anterior margin bearing long 
yellow hairs, some of which extend backward as far as the 
middle of the wing; veins and some membraneous areas of 
the wings bear flat, scale-like hairs. Forewing 1 : fork R4 + 5 
deeper than R2 + 3 ; Ml + 2 divide below the separation of R4 + 5. 
The male genitalia have been figured by Banks. 
$ Similar to the male in size, coloration and venation, ex- 
1 The figure of the wing of this insect given by Banks (1905) is not 
quite correct, and the figure of both fore and hind wing published by 
Ulmer in the Genera Insectorum (pi. 13, fig. 114) is likewise incorrect. 
Ulmer accidently labels this wing Notiopsyche mexicana.
