of the base to the anal angle, and the dorsal margin is narrowly 
yellow ; apical cilia yellow. Posterior wings smoky-fuscous, 
witha broad yellow pterostigma. Legs brownish-ochreous. Ab-

This peculiar insect, which, from its structure and coloration, 
cannot be confounded with any other species, is common about 
waterfalls and torrents in many parts of these islands. It delights 
to sit on the green mossy boulders usually to be found in moun- 
tain streams. It occurs in summer in various localities in Devon- 
shire, Wales, the North of England, &c., and also in Scotland, 
and at Killarney in Ireland. 
Note.—The two species of Lepidoptera, erroneously described as Trichoptera, 
and referred to at p. 3, are as follow :— 
1. Acentropus niveus (Phryganea nivea), Oliv., Steph. Ill. p. 150, 1=Zanele 
Hansoni, Steph.—Acentropus Garnonsii, Curt. Brit. Ent. pl. 497. 
2. Narycia elegans, Steph. Ill. p. 154, 1, pl. xxxiii. fig. 4, identical with 
Lampronia melanella, Steph. Il]. Haustell. iv. 358, 8—Xysmatodoma melanella, 
Zell., Sta. 
Kolenati inserts N. elegans in part 2 of his Gen. et Spec. Trichop. p. 294, 
but does not appear to have been personally acquainted with the insect; his 
figure, pl. v. fig. 62, is an exact copy of that of Stephens.
