British Species of Caddis-flies. 21 
I have never seen these insects alive, but they are said to repose 
with their wings flatter than in other genera.

Antenne testaceous. Head testaceous, with pale yellowish 
hairs. Palpi testaceous. Prothorax thickly clothed with pale 
yellowish hairs. Mesothorax testaceous. Anterior wings pale 
straw-colour, sometimes with an appearance of faint greyish 
reticulations on the membrane towards the apex ; veins brown, 
distinct. Posterior wings hyaline, yellowish at the apex; 
veins scarcely darker, excepting the apical. Legs testaceous. 
Abdomen brown, paler beneath. In the male the upper margin 
of the last abdominal segment has a long fringe of yellow hair ; 
app. sup. not visible; app. inf. curved: upwards, from the base 
arises a long thin piece, curved upwards and inwards, reaching 
to the upper margin. 
Expanse of fore-wings 11—15 lin. 
Not uncommon in the fen district of the eastern counties, 
appearing in May, and probably continuing out all the sum- 
mer and the early part of the autumn. 
The females appear to be rare, for, although I have examined 
upwards of twenty individuals, only two are of this sex. 
A, picta, Kol., has been erroneously included in our lists. (See 
remarks to Phryganea obsoleta, p. 16.) 
Fam. LIMNEPHILID. 
Antenne about the same length as the wings, basal joint always 
much longer and stronger than the others; ocelli always present ; 
maxillary palpi very slightly hairy, three-jointed in the males, 
joints nearly cylindrical, basal joint short; maxillary palpi of the 
females five-jointed; body less robust than in the Phryganide; an- 
terior wings various in form, usually only slightly clothed with hair, 
but sometimes with numerous strong erect hairs, neuration not 
very strong, discoidal cell always closed (in both pairs of wings), 
long andnarrow, subcostal vein not united to the costa bya transverse
