British Species of Caddis-flies. 19 
a cylindrical tube, composed of root-fibres and pieces of leaves 
arranged in a spiral manner. 
Of this genus we have in this country only one species, a dull- 
coloured insect, but some of the Continental and American species 
are remarkable for the sharpness and contrast of their markings. 
Kolenati in the first part of the ‘‘ Genera et Species Trichopte- 
rorum” incorrectly applies the generic term Anabolia to these 
insects, but corrects his error in the second part (p. 284).

Antenne black. Head shining black. Prothorax thickly 
clothed with reddish-ochreous hairs, most evident beneath, 
especially in life. Mesothorax shining black. Anterior wings 
uniform, shining fuscous, the veins piceous and very distinct. 
Posterior wings paler, but otherwise similarly coloured. Legs 
fuscous ; posterior tibiae ochreous, fuscous at the base. Abdo- 
men dull, blackish. In the male the upper margin of the last 
abdominal segment has a fringe of long hairs in the middle, and 
is furnished with a long triangular process, fringed with very 
long somewhat ochreous hairs; app. sup. small, not very evident; 
app. inf. very broad, shining black, furnished at the apex with a 
long moveable spine-like process directed downwards. In the 
female there are two short obtuse somewhat converging app. 
intermed., and two longer curved app. inf., the latter not always 
visible ; the abdomen of the female is broader and more depressed 
than that of the male. 
Expanse of fore-wings ¢ 14—15 lin.; 9 17—18 lin. 
Larva dull green, with a slight reddish tinge. Head and prono- 
tum yellowish, with two parallel slightly-interrupted black stripes,
