which colour extends along the costa nearly to the middle of the wing, and is spotted 

 with purplish fuscous : on the costa are two conspicuous white spots, one on each side 

 of the dark fascia ; beyond these are two or three smaller ones near the apex : cilia 

 fuscous. Posterior wings griseous, with paler cilia. 



This species is most readily distinguished from all its congeners by the ochreous 

 base of the purple anterior wings, and from semifusca it is further distinguished by the 

 two conspicuous white spots near the middle of the costa, which in that species are 

 entirely wanting. 



It appears before any other of the hedge-feeding Argyresthise, and seems most at- 

 tached to blackthorn (Prunus spinosa). I met with it this summer at the end of May, 

 nearly a fortnight before ephippella or nitidella. Like its congeners it keeps out a 

 long while, but the specimens taken after the middle of June are rarely fine. 



Zeller states that according to Fischer von Roslerstamm it is " abundant on sloe- 

 bushes at Reichstadt, in Bohemia, in May and August," but Zeller himself has never 

 met with the second brood, and I believe it has not been observed in this country. 



The mendicella of Hubner (Tin. 179) is the Tinea ferruginella of the Continent, — 

 Tinea ustella of Haworth and Stephens. 



I have given under nitidella my reasons for not agreeing with Zeller and Dupon- 

 chel in considering this species the tetrapodella of Linneus ; the fascia in this species 

 is almost straight, — how then can it be " lunula fusca ? " It is unfortunate that Zel- 

 ler has given no reason for naming it tetrapodella. It is almost unnecessary to remark 

 here that Zeller is quite incorrect in giving the tetrapodella of Stephens as a synonyme 

 for his own tetrapodella, though, as Stephens has only copied the Linnean description, 

 it is questionable how he could have done otherwise ; yet this species being undoubt- 

 edly the mendicella of Stephens, it cannot also be his tetrapodella, which — according 

 to his cabinet — is the pruniella of Zeller, though, as the description of Linneus in no 

 way applies to that species, it is a pity it was inserted in the ' Illustrations.'

Expansion of the wings A\—b\ lines. Head yellowish. Face yellowish. Palpi 

 yellowish. Antenna? yellowish, with hardly any appearance of annulations. Thorax 

 yellowish, with the sides bronze-coloured. Abdomen fuscous. Legs tawny-fuscous. 

 Tarsi fuscous, with paler spots. Anterior wings of a resplendent bronze-colour, with 

 the inner margin pale yellowish, very narrow at the base, but widening out suddenly a 

 little before the middle, till it occupies nearly half the wing ; here it is interrupted 

 perpendicularly by a dark fascia, which can generally be traced across the wing to the 

 costa, being, however, least distinct in the middle of the wing ; beyond this the inner 

 margin is again broadly pale to the anal angle : two pale spots are observable on the 

 costa immediately beyond the dark fascia: cilia dark fuscous. The pale portion of 

 the inner margin is marked with numerous, short, transverse, bronze-coloured streaks : 

 this character at once distinguishes it from all the other species belonging to this sec- 

 tion. Posterior wings grayish, with a violet tinge in certain lights ; cilia paler. 



This species is at once distinguished by the colour of the head from all the other 

 species of this group, except conjugella and the var. b. of albistria : from the latter the
