Antennz dark fuscous, annulated with white on the basal half, 
Head clothed with cinereous hairs. Palpi fuscous. Mesothor: x 
fuscous. Anterior wings long and very narrow, pointed at the 
apex; cinereous, the longitudinal veins regularly dotted with 
blackish; fringes greyish-ochreous; the three transverse veins. 
forming the anastomosis placed successively rather behind one 
another, that closing the discoidal cell being nearest the apex. 
Posterior wings grey, subhyaline, with grey fringes. Legs greyish- 
ochreous. Abdomen greyish, with pale lateral lines. In the 
male there are two needle-shaped styles, which I consider app. 
intermed., but apparently no trace of app. sup.; app. inf. very 
large, dilated at the apex and notched, hairy, very similar in 
shape to those of the genus Sericostoma ; below the app. intermed. 
is a large upper penis-cover (or perhaps the penis itself?) 
Expanse of fore-wings 6—S} lines. 
Has been bred by Mr. Parfitt of Exeter, but I have no de- 
scription of the larva. Case a straight tube, 63 lines long, taper- 
ing almost to a point at the smaller end; construcied of silk, 
without any extraneous substance attached to the outside; the 
mouth nearly circular and dilated. 
A delicate species, frequenting slowly-flowing rivers, and ap- 
pearing in summer; not common. 
In Curtis’ Collection two species were placed under the label 
tineiformis, but the description shews that this was intended to 
bear the name. In Stephens’ Collection three species are in- 
cluded under the one label, but here also his description shows that 
this was intended. The types of attenuatus, Stephens, I believe 
to be examples of this, in which the hairy clothing of the wings 
has been rubbed off,
