Vorhies—Studies on the Trichoptera of Wisconsin. 669 
tant from the larval habitat. Strange to say, on Oct. 14, Prof. 
Marshall brought in a specimen picked up on the street. This 
late elate suggests the possibility of there being two broods.

JSleophylax autumnus nov. sp. 
Imago .—Length of body, 5-7 mm. Expanse, male, 15-17 
mm.; female, 16-18 mm. Antennae, 8-9 mm. in length, the 
basal portion fulvous, more fuscous at the apex, the basal joint 
clothed with gray hairs. Palpi fulvous. Head fulvous, clothed 
with gray hair: a pair of large warts between the bases of the 
antennae just above the median ocellus; a smaller, transverse 
pair just posterior to the paired ocelli, and a larger transverse 
pair posterior to these, all hairy. Thorax fulvous, gray hairs 
on the warts, of which there are on the pronotum, a small 
median pair, and a larger, lateral, transverse pair: on the meso- 
notum, a small longitudinal pair separated by a median im¬ 
pressed line, and a large median one on the posterior half of 
the segment. Abdomen short, robust, brown above, paler be¬ 
neath; not hairy, except on terga of 7th and 8th segments: a 
conspicuous tooth on the 7th ventral segment of the male, not 
on both penultimate and antipenultimate segments, as given for 
the genus. Legs fulvous, tibiae and tarsi with black spines; 
spurs fulvous, 1, 3, 4. Anterior wings fuscous, guttate with 
yellow, rather densely pubescent with black and golden hair: 
veins brown: on the inner margin a long yellow spot extending 
out from the body, another on the middle of the margin, fuscous 
between the two and without the latter at the arculus; a smaller 
yellow spot in the last apical cell: a transparent V-shaped spot 
in the darker region at thyridium and arculus. A dorsal view 
of the insect with wings folded shows a characteristic yellow 
median figure, consisting of a double spindle followed by a 
small dot, the whole on a fuscous background. A group of 
long black hairs near base of wing in unrubbed specimens; 
outer margin with fringe of black and golden hairs. Posterior 
wings sub-hyaline, sparsely clothed with hairs which are darker
