coming confluent with the subdorsal. In the posterior wings five 
veins proceed from the discoidal cell to the hinder margin, one to 
the costa. Species 1-4, 
(In species 4, Stephensi, the second joint of the palpi can scarcely 
be called loosely scaled.) 
B. The pale costal spot of the anterior wings obsolete; the tufts of 
scales extremely small; the apex of the subdorsal vein simple, the 
thickened apex of tle submedian not connected with it. Species 
5-9. 
(In species 6, ochraceella, the apex of the subdorsal vein is fur- 
cate, as in section a. I place species 7, Phragmitelia, here, though 
Thad previously made a distinct genus of it, Limnecia: it accords 
well with ochraceella, only exaggerating the peculiarities from its 
larger size.)- 
c. The anterior wings with no pale costal spot; below the furcate api- 
cal yein ¢hree veins run into the hinder margin; the subdorsal vein 
only furcate at the base; the submedian not thickened. Sp. 10, 11. 
Many of the species of this genus are very beautiful, the an- 
terior wings being frequently of varied colours, and the tufts on 
them give them, when seen at rest, a singular appearance ; the per- 
fect insects are rather sluggish, and some are consequently rarely 
met with; some which only appear towards the end of the summer, 
such as Zpilobiella, ave more frequently met with in the spring 
after hybernation. Most of the species have probably only one 
brood, but Staintoni is double-brooded. The few known larvee 
are either leaf-miners, or feed in the terminal shoots of plants.

creruleo-fuscis, ochraceo marmoratis, macula dorsi basali fee costam

Head and face white. Palpi white, the terminal joint with a fuscous 
ring before the apex. Antenne fuscous. Anterior wings bluish-fus- 
cous, marbled with ochreous; a large basal spot which is expanded on 
the inner margin and almost touches the costa, and an interrupted oblique 
hinder fascia, are white ; a slender white streak arises in the middle of 
the costa, and after passing under a round black spot on the disc, runs 
into the white fascia, which is interrupted in its middle by a grey and 
a tawny spot; three tufts of black scales lie on the fold, and three 
others above them; cilia tawny fuscous. Posterior wings fuscous, with 
paler cilia. 
Has occurred in various localities at Deal, Fulham, near Bristol, 
in the south of Scotland, and in the Cambridgeshire fens in July ; 
but nowhere common.
