Monograph on Argyresthia. ix 



Sp. 8. pulchella, Lienig. 

 Argyresthia pulchella, Lieuig, Isis, 1846, S. 293, 4. Zeller, Linn. Ent. ii. 261. 



" Pulchella is smaller and broader winged than conjugella, of the size of tetrapo- 

 della. Head, base of the antennae and palpi snow-white ; antenna? annulated, white 

 and brown. Legs more finely marked than in conjugella. 



"Anterior wings violet-brown, with darker patches; as such the bordering of the 

 hinder part of the snow-white inner margin is conspicuous ; the white inner margin 

 forms a streak which expands posteriorly, and is then by the ordinary fascia cut off 

 straight and perpendicularly : beyond this fascia, which cannot be traced more than 

 half across the wing, there is no other pale patch, but only some white scales along the 

 hinder margin. On the costa, in the middle, are white spots, and before the apex a 

 white hook, the end of which is turned very obliquely inwards ; beyond it, thus nearer 

 the apex of the wing, is still a very pale and much finer streak, to be observed in the 

 costal cilia : cilia, at the apex of the wing, dark brown, palest in the middle, the upper 

 part gray-brown. 



" The costal hook is very distinct on the violetish brown-gray under-side: the costa 

 has white spots, and the inner marginal streak shows through very faintly. 



" Posterior wings gray, with a violet tint; cilia brownish gray, at the base rather 

 yellowish. 



" My single female specimen, the left wing of which is rubbed, I took for conju- 

 gella; the sight of Madame Lienig's very beautiful specimen convinced me that both 

 were the same, and a truly distinct species." 



I have not yet seen this species, and am not therefore aware that it has occurred 

 in this country ; but as it most probably will be discovered, I make no apology for in- 

 troducing Zeller's description of it here, as from that the fortunate captor will at once 

 be able to name his insect. 



Zeller's own specimen was " taken near Gastein, on the 12th of August."

Expansion of the wings 4|— 5£ lines. Head white. Face yellowish white. 

 Palpi yellowish white. Antennas white, annulated with black. Thorax white. Ab- 

 domen fuscous. Legs whitish. Tarsi whitish, spotted with black. Anterior wings 

 purplish fuscous, with the inner margin white, interrupted rather beyond the middle 

 by a dark purplish brown fascia, which cuts it off perpendicularly ; the fascia after- 

 wards curves a little, but terminates on the costa ; immediately beyond this fascia the 

 white inner margin is rather broader than before it, but it terminates at the anal an- 

 gle ; at the base of the wing the whole of the dark portion of the wing is ochreous,
