168 GELECHID®. 
vena subdorsalis simplex; posteriores: e venula transversa vena 
unica procedit. 
Head retracted, with appressed scales, in front obtuse. Ocelli none. 
Antennx with thickly-set, compressed joints, attenuated towards the 
apex (in one continental species with erect projecting scales in the mid- 
dle, Nodosella). Tongue of moderate length, with a few scales towards 
the base. Palpi reflexed; the second joint compressed, smooth; the 
terminal joint pointed. Wings elongate, with the apex produced; the 
posterior with obtuse anal angle. In the anterior wings the narrow, 
discoidal cell is extremely elongate; the lower branch of the apical vein 
runs into the costa before the apex; the subdorsal vein is simple; in 
the posterior wings a single vein proceeds from the transverse vein. 
We have but two species of this genus in this country; they 
are exceedingly similar, the main point of difference being in the 
antennae. A third species is known on the continent, also differ- 
ing in the antenne. The larva of none of the species are known; 
Ratzeburg, it is true, says of Lewwenhoekella, “bred by Herr Zebe 
from the bark of larch-trees,” but in this must be some mistake, 
as the perfect insects are not found amongst trees, but frequent 
open flowery places amongst short grass.

Head and face very dark bronzy-green. Palpi dark fuscous, inter- 
nally dirty whitish. Antenne entirely dark fuscous. Anterior wings 
deep orange, with the base, costa, inner and hinder margins dark fus- 
cous, with six golden-green spots, the first rather transverse on the 
costa near the base, the second on the costa before the middle, the third 
elongated, pointing inwardly, near the costa towards the apex (produced 
on the costa as a pale yellowish-white spot), the fourth on the fold below 
the first costal spot, and almost united with it, the fifth on the fold 
before the middle is smaller, and the sixth is larger on the inner mar- 
gin beyond the middle; above the anal angle are some golden-green 
scales not forming a definite spot; cilia fuscous. Posterior wings fus- 
cous, with a slight bronzy tinge, with pale fuscous cilia. 
A specimen is in Mr. Curtis’s collection ; and I have seen a few 
others.
