1412 Mr. R. M‘Lachlan’s Monograph of the 
middle of the upper margin of the last abdominal segment, on 
each side of which are placed the long, narrow, finger-shaped 
hairy app. sup.; beneath the lobe is the very long and narrow upper 
penis-cover, which is curved strongly downwards; on either side 
of this cover, and rather below it, is a needle-shaped, upcurved 
stile, which may be considered as the app. intermed.; app. inf. 
long and thin, the apex directed slightly downwards ; the ventral 
margin of the last segment thickly fringed with yellow hairs. In 
the female there are two very large obtuse lateral valves. 
Expanse of fore-wings 63—9 lines. 
Occurs in summer about standing waters; not uncommon in 
the metropolitan district. 
It is possible that this may be the Phryganea tineoides of Scopoli, 
and it has been referred to that species by Dr. Hagen. But I think 
it best to retain Curtis’ name, as there must be uncertainty as to 
what was intended by Scopoli. His diagnosis is simply “ dle 
antice fusco-ferruginee. Antenne corpore triplo et ultra longiores, 
fusce, albo-annulate.” Afterwards he says, “ dle postice fusce,” 
which gives some probability to the assumption that this was the 
species described.

Antenne whitish, annulated with brown on the basal half. Head 
clothed with whitish hairs. Palpi fuscous. Anterior wings 
rather dilated towards the apex, grey, thickly sprinkled with 
fuscous atoms, a large paler space a little before the apex ; fringes 
pale fuscous, interrupted with whitish ; neuration indistinet, the 
third and fourth apical cells straightly truncated at the base. 
Posterior wings smoky-grey, with golden and purple iridescence ; 
fringes grey, occasionally interrupted with white. Legs silvery, 
the tarsi faintly annulated with fuscous. Abdomen brownish- 
ochreous, with paler lateral lines. In the male the app. sup. are 
rather short, slender and hairy; app. inf. apparently bisarticulate, 
the apical joint curved upwards; above the app. inf. on either side 
there is apparently a nearly quadrate lateral plate, slightly excised 
at the apex. Female possessing very small lateral valves. 
Expanse of fore-wings 63—10 lines.
