British Species of Caddis-flies. 57 
Genus Stenopuytax, Kolenati. 
Antenne, head, palpi, legs, &c., with the same characters as 
in Anabolia (p. 53). Anterior wings slightly broader at the apex, 
rather more hairy, with well-marked paler spots at the thyridium 
and behind the anastomosis; apex parabolic or circular. Pos- 
terior wings as in Anabolia. Abdominal appendices in the male 
varying according to the species; app. intermed. curved, diva- 
ricating; app. inf. sometimes well developed; penis-sheaths 
apparently simple, fine, needle-shaped and curved; penis thin. 
Larva inhabiting swiftly running streams. Case a straight 
cylindrical tube composed of small stones, temporarily fixed at 
one end to large stones, &c. When about to change to a pupa, 
the larva closes the case with larger stony fragments, retires to a 
cavity in a large stone or to some other convenient place, and there 
fixes it firmly. 
As before mentioned (p. 54) this genus is very closely allied 
to the preceding and differs chiefly in the habits of the larve. 
The anterior wings are, however, decidedly broader than in the 
species of dnabolia, and this character will readily separate the 
perfect insects of Stenophylax from Limnephilus. 1n this respect 
they resemble the larger species of Halesus, and were included in 
that genus by Stephens. The quadricalcarate posterior tibize 
will readily separate them. 
These are large insects of powerful flight; they are very fond 
of taking refuge in fir trees in woods and are readily beaten from 
their hiding-places. They also come rather freely to sweet mix- 
tures placed on trees to attract moths.
