Head retracted, with appresscd scales, in front obtuse. (3celli none, 

 Antennie with thickly-set, compressed joints, attenuated towards the 

 a])ex (in one continental species with erect projecting scales in the mid- 

 dle, NodoficUa). 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 a|)ieal vein 

 runs into the costa before tiie apex ; the subdorsal vein is siDipJe ; in 

 the ))osterior wings a s'uiffh vem proceeds from the transverse vein. 



A\^e have but two species of this genus in this country ; tlicy 

 are exceedingly similar, the main point of difference being in the 

 antennse. A third species is known on tlie continent, also differ- 

 ing in the antennae. The larva of none of the species are known; 

 Ratzebnrg, it is true, says of Lcuwcnhocl-elln, " bred by Herr Zebe 

 from the bark of larch-trees," but in this nuist be some mistake, 

 as tlie perfect insects are not fou)ul amongst trees, but frequent 

 open ilowery places amongst short grass.

 deep orange, with the base, costa, inner and hinder margins dark fus-

 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-wliite spot), the fourth on the fold below 

 the first costal spot, and almost united with it, the fifth on tlie fold 

 before the middle is smaller, and the sixth is larger on the iimer mai'- 

 giu beyond the middle ; above the anal angle are some golden-green 

 scales not forming a definite spot ; cilia fuscous. I'osterior wings fus- 

 cous, with a slight l)ronzy tinge, with pale fuscous cilia.
