Vorhies—Studies on the Trichoptera of Wisconsin. 675 
eral black border and the dark diagonal band. On either side 
of a light median line, is a small transverse oblong spot posterior 
to a black dot. Metanotum with chitinous patches well devel¬ 
oped. Thoracic segments and first abdominal segment beset 
with short brown hairs. Legs yellowish-brown; femora and 
tibse spotted with dark brown. Lateral line on segments 2-8. 
Gills complex, from one to seven branches in a place, the simpler 
ones near the lateral line. Tig. 6. 
Through an error in making the diagram of the gill formula 
in a former paper (1905), gills were located on the eighth seg¬ 
ment, which is entirely without them. 
Pupa. —Length, 12-16 mm. Width, 3 mm. Antennae ex¬ 
tending to the 7th segment, or as long as the body. Body white 
or greenish-white. Dorsal spines, III, 2. 2-3. 2-4+10-12. 3. 
3-4, VTI. Lateral line begins on anterior edge of 6th segment, 
and forms a loop under the 8th. Gills complex, each with 4-12 
branches, in the same positions as in the larva. Abdomen end¬ 
ing in two long processes. Mandibles sharp, knife-like, slightly 
serrate on cutting edge, a little longer than the labrum, which 
bears five long hooked hairs on either side. 
Eggs .—The eggs of this species are light greenish, contained 
in a grayish translucent mass of gelatinous material, possessing 
considerable rigidity. These masses appear to be made up of 
a continuous string of material laid in a regular manner, with 
somewhat the appearance of an irregular coil 6-9 mm. in di¬ 
ameter. TTone have been found actually beneath the water, but 
always in moist, warm situations, i. e., beneath the larger stones, 
where they would not be subjected to extremes of heat or cold, 
or to sudden changes.
