palpismall; the first and second joints short, the latter the longer ; 
the third equal in length to the others united. Mesothorax large, 
hairy, somewhat trancated in front. Anterior wings long and nar- 
row, the apical portion slightly dilated, the apex rather acute ; 
hairy clothing slight; discoidal cell small, closed ; cellula thyridit 
long ; apical forks 1, 2, 3, 4 and 5 all present.* Posterior wings 
much shorter than the anterior, and more than twice as broad, 
opaque ; costal margin arched; apex obtuse; anal portion largely 
developed ; discoidal cell small, closed ; apical neuration irregular; 
forks 3 and 5 present; a transverse vein below the discoidal cell, 
another below the first and more towards the apex, and a long 
curved one from the base of fork 5 to the first of the costula. 
Legs moderately long and slender. Spurs 3-4-4; anterior tibia: 
with two short and nearly-equal apical spurs, and one short 
median ; intermediate and posterior tibiae each with two long 
median and apical spurs, the inner spur of each pair being the 
longer. Abdomen long and moderately robust ; anal appendices 
well developed and complicated. 
Stenopsyche differs widely from any described genus of Hy- 
dropsychide. The combined characters of the long and narrow 
wings, the neuration, and the tricalcarate anterior tibia, will enable 
it to be readily recognized. At present I know of only one spe- 
cies, and of that only the male sex. It is probable, judging from 
analogy, that the female may possess dilated intermediate legs,
