24 Mr. R. M‘Lachlan’s Monograph of the 
but is considered as forming only a section of Limnephilus by Dr. 
Hagen. The single British species has a general appearance and 
habits so different from the species of that genus, that I think 
it best to adopt Kolenati’s view and keep it distinct.

Antenne testaceous, with indistinct darker annulations. Head 
brownish in the middle, bordered with testaceous. Palpi tes- 
taceous. Prothorax clothed with brownish hairs. Mesothorax 
shining, brownish. Anterior wings straw-yellow, darkest towards 
the dorsal margin, where there are sometimes well-defined brown 
irrorations ; veins testaceous, with black hairs set at regular dis- 
tances, giving them the appearance of being finely pointed with 
black. Posterior wings hyaline, sometimes slightly yellowish at 
the apex ; apical veins distinct, somewhat brownish. Legs tes- 
taceous, with black spines and testaceous spurs. Abdomen grey- 
ish-brown above, ochreous beneath. In the male the upper 
margin of the last abdominal segment is rounded; app. sup. 
broad, flat, very obtusely rounded, yellowish and fringed with 
short hairs; app. intermed. short, divergent, shining brown, 
scarcely visible ; app. inf. nearly obsolete, in their place is a thin 
tuft of blackish hairs. In the female the extremity of the abdomen 
is obtuse, with scarcely any appendices; from the middle of the 
last segment above them arises ashort broad triangle, on each side 
of which is a small hairy valve; lateral valves short, broad and 
rounded. 
Expanse of fore-wings 6—9 lines. 
Appears in summer and autumn, frequents the sides of canals 
and the weedy margins of ponds and marshes, and in the day- 
time conceals itself under the herbage and dead leaves, &c., 
running about with great activity, if disturbed. The male seems 
to be less frequent than the female, at least this is my experience. 
Genus Grammorautius, Kolenati. 
Antenne with long curved basal joint. Head above nearly 
quadrate. Maxillary palpi of male with short basal joint, two
