AQUATIC INSECTS IN NEW YORK STATH 281 
the eyes and ending at the middle of the thorax on its ventral 
side. Palpi ending in a J-shaped hook. 
Respiratory horns cylindric, becoming laterally flattened at 
tip, erect but bent anteriorly in their distal third. Wings and 
legs closely covering the ventral surface; tips of the wing cases 
reaching the base of the fourth abdominal segment; legs much 
curved beneath the wing cases; tarsi laid straight along the 
ventral side of the abdomen, those of the fore legs reaching 
the constriction of the middle of the fourth, those of the middle 
and hind legs, the apical circlet of spines on the fourth abdom- 
inal segment. Thorax unarmed; a low carina between the 
respiratory horns, ending posteriorly in a series of transverse 
corrugations, on either side of which are spots and lines of 
‘darker color. 
Abdominal segments transversely divided by a constriction, 
both before and behind which, dorsally and ventrally, is a broad 
pale area bordered by darker brown, forming at the sides a 
band which includes the row of spiracles at the anterior border 
of segments 1-7. In the pale band on the lateral margin there 
arises a stout spine in the basal half and a larger one in the 
apical half of segments 2-7; here are also numerous brown 
dashes, merging into the larger, phalerate markings already 
described. ! 
On the dorsal side in the apical half of each of segments 1-7 
there is a transverse row of about a dozen sharp, minute thorns, 
very minute on 2, but becoming larger posteriorly; on the ven- 
tral side of same is a similar row of stouter thorns, becoming 
much stouter and fewer and nearer the hind margin posteriorly, 
while before them, near the middle constriction, stand an iso- 
lated pair of similar size. ‘On segment 8 there are three pairs 
of stout spines on the dorsum, the intermediate pair being the 
largest, and there are three lesser pairs on the venter. On the 
end of the abdomen, and perhaps belonging to a ninth segment, 
there are two other pairs of spines, a larger yellowish, brown 
tipped, straight pair, and a smaller, terminal, upcurved pair.
