AQUATIC INSECTS IN NEW YORK STATE 419 
the dorsal surface, the lateral ones near the base of the antennae, 
the others more caudad [fig.2]; eyes large; antennae flattened, 
wider on the portion below the hair tuft, which is composed of 
20 to 30 loosely feathered, long hairs on the side at about two. 
thirds its length from the base; its apex with four slender and. 
one stout bristle besides the short apical joint. The rotatory 
fan [fig.5f], labrum [lr] and epipharynx [e] normal; clypeus. 
with the usual pair of setae; the mandibles with a long, stout,. 
~ curved, pale brown spine with a serrate inner margin, projecting: 
beyond the black teeth. ‘A pair of small spines are found on the- 
dorsal surface of the maxillae, and a small seta near the apex 
[fig.4¢]. The cephalic margin of the labium [fig.4l] is elliptic, 
the median tooth longer than the others, and the hypopharynx. 
[h] is of the usual shape [pl.44, fig.5]. The thorax is rounded;, 
arranged on the dorsal surface in a transverse row near the 
cephalic margin are 10 or 12 equally spaced tufts of long hairs, 
the median tuft largest. A little caudad of the middle line, near 
the lateral margin are six or eight long hairs in an irregular 
transverse row, and on the lateral posterior margin, are two 
tufts of five or six short hairs each. The outline of the abdomen 
presents a sinuous margin, the segments being somewhat con- 
stricted at the incisures. On the prominence of each side of the 
segments are three or four moderately long hairs. The lateral 
combs of the eighth segment consist of a patch of about 50 
spines. Caudad of the lateral comb is a tuft of about eight 
feathered hairs, and dorsad and ventrad of this is another 
smaller tuft. The ninth segment has five or six long setae on 
the dorsocaudal margin, 13 or 14 branched hairs of about six 
branches each on the caudal third of the ventral surface and 
four rather long sharply pointed blood or tracheal gills. The 
breathing tube is rather long, with from 10 to 15 serrate spines: 
in a longitudinal row on each side, and on the ventral surface 
are three pairs of long and several short tufts of hair. 
Pupa [fig.6,7]. The breathing trumpet is comparatively long,. 
widest at the apical third, its opening extending downward on 
one side to almost the middle. On the abdomen are the usual 
bristles, those on the lateral margin being larger toward the 
caudal end. Swimming paddles are of the usual shape.
