56, app. 
Antenne dark brown, with slightly paler annulations. Head, 
palpi and thorax dark brown above. Anterior wings pilose, 
mouse-grey, with elongated pale spots in the cells; a large 
somewhat bilobed pale spot at the thyridium, and two or three 
greyish markings at the base towards the dorsal margin. Poste- 
rior wings greyish, subhyaline, darker at the tips. Legs greyish- 
brown, with black spines. Abdomen dark blackish-fuscous 
above, paler beneath. In the male the upper margin of the last 
abdominal segment is cut off straight; app. sup. concealed in the 
last segment, small, apparently divided; app. intermed. acute, 
divergent, testaceous, the upper half blackish; app. inf. produced 
into a long cylindrical style, directed upwards, testaceous, black 
at the apex, which is knobbed, the lower part fringed with long 
yellowish hairs; penis-sheaths and penis small, scarcely visible. 
In the female above, there is a large, open, emarginate, tubular 
piece. 
Expanse of fore-wings 14—16 lines. 
Larva with the head and thorax brown. The pronotum with 
several black markings on its posterior portion, which are joined 
to those on the mesonotum, which is margined by a black line. 
The metanotum has four scaly points from which arise hairs. 
Abdomen yellow, very stout, with few respiratory filaments. 
The feet strong, fawn-coloured. (Pictet.) 
Case formed of stony fragments placed in a regular manner, and 
attached to the underside of stones in running waters. (Pictet.) 
A not uncommon species by most swiftly-running streams, ap- 
pearing in summer and autumn. Scotch specimens are darker 
than Southern ones. 
In Trans. Ent. Soc. ser. 3, i. 237, I separated latipennis of 
Curtis as a distinct species, but am now disposed to think that it 
belongs here; the types were certainly paler than is usual in 
stellatus, but they may have been faded. The description in 
Ent. Ann., 1859, p. 94, 36, applies to areatus of Kolenati, a 
species excessively similar in general appearance, but differing in 
the app. inf., which are produced into a long acute point. This 
species has not yet been discovered in Britain.
