_ 40 Mr. R. M‘Lachlan’s Monograph of the 
Expanse of fore-wings 12—16 lines. The female somewhat the 
smaller. 
Common in the Norfolk Fens in autumn. I have also seen it 
from Hartlepool, Willesden, Killarney, &c. 
This species, though probably widely distributed, is not con- 
tained in the collections of Curtis or Stephens. It is an insect 
not well understood, and, unless there be a nearly allied species, is 
liable to great variation in Continental examples, both in size and 
coloration. 
There appears to be little doubt that it is not the true concen- 
tricus of Zetterstedt, and I have therefore given it a new name. 
The position of the insect is also a matter of some uncertainty. 
Kolenati assigns to it about the same position as I have here given 
but Dr. Hagen places it at the end of the first section of Sten 
phylax. As 1 have elsewhere stated (Tr. Ent. Soc. 3rd ser. 1. 240), 
the shape of the wings agrees more with Limnephilus than with 
Stenophylaz, and the fourth apical cell in the posterior wings is 
decidedly narrower than the second, whereas in Stenophylax (and 
Anabolia) they are of the same breadth. The posterior wings of 
the male are not furnished with a beard.

Antennz reddish-ochreous. Head reddish, fuscous in the 
middle above. Palpi reddish-ochreous. Mesothorax reddish. 
Anterior wings yellowish-brown, shining, with whitish-hyaline 
longitudinal streaks, viz., two long ones towards the costal and 
dorsal margins respectively, a shorter one in the middle of the 
disc, about five in the apex, occupying the first, second, fourth and 
fifth apical cells, and an oval one at the base of the sixth; ptero- 
stigma yellowish-brown. Posterior wings hyaline, with the tips 
faintly yellowish. Legs reddish-testaceous, with black spines. 
Abdomen reddish-ochreous. In the males the upper margin of 
the last abdominal segment is cut off straight ; app. sup. broad, 
flat, with a deep circular notch on the apical margin, the edges 
blackish, with long hairs; app. inf. small, yellow, with a few 
blackish hairs at the apex. 
Expanse of fore-wings 12—14 lines.
