base; each segment has also a rim of golden-brown hairs on the 
posterior border ; venter covered with yellowish scales. 
Legs with the coxae yellowish-brown, femora pale beneath, 
brown scaled above, with a very deep apical ring and a small 
white ring at the extreme apex; tibiae brown, with an ochra- 
ceous lustre and an apical band of yellow; tarsi uniformly dark 
brown. The legs appear quite pale in some lights; ungues equal 
and simple. 
Wings with the veins covered with long brown scales, except 
the fifth and its lower branch; the first sub-marginal cell very 
long and narrow, much longer than the second posterior cell, its 
stem extremely short, the fork at least seven times as long as the 
stem; base of the cell much nearer the base of the wing than 
that of the second posterior cell; the stem of the latter equal 
to about half the length of the cell; posterior cross-vein about 
equal in length to the mid cross-vein, and distant from it about 
its own length ; fringe brown, with pale reflections. Hal teres 
pale ochraceous, slightly darker brown at the apex. 
Length of J , 4 • 5 to 6 mm.

The wings are not so thickly scaled as in the 9 ; the first 
sub-marginal cell is longer and narrower than the second 
posterior cell, its stem about one-fourth the length of the cell, 
the base of the cell is nearer the base of the wing than that of 
the second posterior cell; the stem of the latter nearly as long 
as the cell itself; posterior cross-vein quite twice its own length 
distant from the mid cross-vein. 
Length. —4*5 to 5 mm. 
Habitat. — Europe generally, from Scandinavia to Italy; 
Malta (Birt); N. America (Hessler). 
Time of appearance. —In Europe in March to July onwards, 
practically throughout the whole year. I have taken specimens 
in every winter month in warm winters.
