British Species of Caddis-flies. 25 
others about equal, long; of the female with short basal joint, 
fourth joint considerably shorter than the 2nd, 3rd or Sth. 
Labial palpi compressed, first and second joints broad, ter- 
minal joint oval. Prothorax moderately developed, hairy. 
Anterior wings long, very narrow at the base, much dilated 
before the acute apex, dorsal’ margin slightly convex, hairy 
clothing very slight, cilia scarcely evident; neuration not very 
strongly marked, radius with a marked bend before its termina- 
tion, no coloured pterostigma, apical veins all reaching the 
anastomosis. Posterior wings hyaline, with a slight excision just 
below the acute apex, a long black apical line following the 
course of the fourth apical sector. Tuibiz slightly spinose; an- 
terior with one long apical spur; intermediate with one long 
median spur and two apical, of which the inner is the longest ; 
posterior with two long apical and two median spurs, the inner the 
longest in both pairs. Anal appendices of the male arranged as 
follows:—App. sup. large, broad and fureate; app. intermed. 
large, flat and straight; app. inf. fine, hairy; sheaths furcate, the 
points approximating ; penis with thickened apex. ‘The female 
has two hairy app. sup., and between these two triangular obtusely 
pointed valves. 
The species on which Kolenati founded this genus appear to 
me to bear him out in his idea, as they have a peculiar facies, 
altogether different from most of the species of Limnephilus with 
which they have been generally associated, and much resemble 
each other, They are large insects inhabiting marshy districts. 
The blackish apical line in the posterior wings is not constant, 
as occasionally specimens are found (aberrantly) without any trace 
of it; these are generally females.
