British Species of Caddis-flies. 15 
obliquely rounded ; ventral lamina short, broad and rounded. 
In the female the lateral lobes are broadly rounded. 
Expanse of fore-wings, 6 17—22 lin.; @ 24 lin. 
Appears in summer with the preceding species, and is, perhaps, 
almost as common. 
These two species are very generally mixed in collections. 
To Dr. Hagen is due the credit of having first pointed out the 
differences (Linnza Entomologica, Bd. 5, p. 363). P. striata is 
always smaller, darker and more uniform in coloration, and the 
female has but small traces of the dark band so conspicuous in 
P. grandis; the structural differences in the appendices are most 
conclusive, but a practised eye can readily separate them without 
regard to these latter characters.

Antenne testaceous, with broad black annulations. Head pi- 
ceous, with grey hairs. Palpi fuscous. Prothorax thickly clothed 
with grey and black hairs. Mesothorax piceous, with two me- 
dian parallel lines of grey hairs. Anterior wings pale grey, 
thickly clouded and spotted with blackish-brown, large dark and 
light blotches alternating along the inner margin, two conspicuous 
white spots, one rather elongate, in the sixth apical cell, and a small 
round one at the base of the third; veins dark fuscous, some- 
times much suffused towards the apex. Posterior wings smoky 
grey, veins darker. Legs testaceous, the anterior and interme- 
diate tibize and tarsi conspicuously, and the posterior indistinctly, 
annulated with dark fuscous. Abdomen testaceous, somewhat 
fuscous above, paler beneath. In the male the last abdominal 
segment and app. sup. are fringed with very long reddish-ochre- 
ous hairs, fuscous at the extremities ; app. sup. foliaceous, short, 
broad and rounded; app. inf. long, curved strongly upwards, the 
tips approximating ; penis long and exserted, pale yellow.

Larva shining greenish, head and pronotum fawn-coloured ;
