moderate, slender with a tuft at the middle. Head-hairs single; an-
teantennal tuft in four. Lateral comb of the eighth segment of many
scales in a patch. Air-tube short, less than twice as long as wide,
the pecten running nearly to tip, the last four teeth widely spaced
and inclosing a six-haired tuft. Anal segment about as long as wide,
the plate reaching the middle of the side; ventral brush with the an-
terior tufts smaller but not separated. Dorsal tuft a hair and brush

This species is locally distributed throughout the eastern
United States, and is recorded from Arizona and New Mexico.
The larvae are found in rock holes along streams and water-
