“Side-piece cylindrical, stout, romldedly trun-
cate at tip, hairy. Claspette small, triangular, soldered to the side-
piece with five terminal setae. Clasper moderately inflated, the tip
tapering, with distinct terminal spine. Tenth sternites large, inner
margin thickened, a point at tip. Ninth tergites undeveloped. Meso-
some a conical cylinder.” (Dyar, 1928.)
Larzla. “Head’ wider than long, a little bulging at the sides.
Antennae long, as long as the head, spinulose; a multiple tuft at about
the middle. Head-hairs single, anteantennal tuft in four. Lateral
comb of the eighth segment of six large scales on a weak chitiniza-
tion, each scale trifid and with long central spine. Air-tube inflated,
about three times as long as basal width; a small pecten of four
spines at base. Anal segment longer than wide, ringed by the plate,
dorsal tuft a long hair and multiple tuft on each side; ventral brush
running the length of the segment. Anal gills longer than the seg-
ment, tapered.” (Dyar, 1928.)
This species. occurs from Montana south to Mexico. Very-
little seems to be known about its biology.

This genus is difficult to differentiate from our other gen-
era. There appears to be no single character or group of char-
acters which will segregate all the species of this genus. Our
species fall in the sub-genus Coqdlettidia which is differen-
tiated bly the characters given in the key. The larvae are read-
ily separated by the striking attenuation of the air-tube which
is fitted for the penetration of the plants from which they se-
