AQUATIC INSECTS IN NEW YORK STATE 410 



the dorsal surface, the lateral ones near the base of the antennae, 

 the others more caudad [flg.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 [flg.Sf], labrum [Ir] 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.4a?]. The cephalic margin of the labium [fig.4^] 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 tw^o 

 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, 18 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.
