Vorhies—Studies on the Trichoptera of Wisconsin. 655 
In the male the superior appendages are broad, short, di¬ 
rected slightly downward, with several teeth at the truncate 
apex; within, each hears a small club-shaped appendage, ending 
in a pencil of yellow hairs. A pair of penis sheaths projects 
from between them above the penis, curving abruptly outward, 
their points extending laterally beyond the superior appen¬ 
dages: these sheaths may be retracted so as to point backward 
rather than outward. The inferior appendages are short, 
broad, nearly meeting medially beneath, clothed with yellow 
hair. 
Larva. —Length, 30-35 mm. Width, 6 mm. Body in life 
dark green with fine colorless markings on the meso- and meta¬ 
thorax, which become more distinct in alcoholic specimens, ow¬ 
ing to the extraction of the green color, leaving the dark 
purplish of the thoracic region as a contrasting color. Head 
yellow: a medium longitudinal band of black on clypeus, some¬ 
what arrow shaped at point of same; on either side of clypeus a 
black band extends from base of mandible to median suture on 
top of head, forming a V narrowly open at the apex; a lateral 
black band extends from the occipital foramen toward, but not 
to, the eye. Gula. dark brown, some color extending beyond its 
Fi f. /• 
lateral sutures. Pronotum black-bordered anteriorly and pos¬ 
teriorly, with the two bands slightly connected along either 
side of the white median suture. Legs yellow with dark outer 
border on coxse and femora: trochanter and femur of each leg 
with inner fringe of bristles; femur of second and third leg 
pectinate with short spines alternating with the bristles; tibia 
and tarsus of second and third leg pectinate with longer spines; 
inner side of coxa of first and second leg beset with linear 
groups of small spines. Dragging hooks consist of one large 
and two small claws. Gill formula, Fig. 1.
