tidis ochreis, violaceo-suffusis ; capillis dilute luteis. Exp. al. 6 lin. 
Head whitish-yellow. Wace and palpi pale ochreous. Antennae 
whitish, annulated with pale fuscous. Anterior wings shining ochreous, 
with a slight violet tinge; cilia paler. Posterior wings rather broad, 
very pale grey, with paler cilia. 
Occurs, not uncommonly, among junipers, in May. 
23. aurulentella (Zell.), Sta. Zool. 1849. App. xl. Alis anticis 
nitidis ochreis, violaceo-suffusis, dovso anguste albo ; capillis niveis. Exp. 
al, 4 lin. 
Head white. Wace and palpi yellowish-white. Antenne white, with 
fuscous annulations. Anterior wings shining-ochreous, with a slight 
violet tinge, the inner margin narrowly white; cilia whitish-ochreous. 
Posterior wings pearly-whitish, with pale ochreous cilia. 
Very common among junipers, in July and August. 
24, decimella, Sta. Sup. Cat. p. 10 (1851). Allis anticis albis, 
striola costa ex basi ad medium, in fasciam obliquam transeunte, strio- 
laque breviore ex basi prope dorsum aureo-brunneis, puncto apicis nigro. 
Exp. al. 3 lin. 
Head, face, and palpi white. Antenne: whitish. Anterior wings 
white, with a golden-brown streak along the costa from the base to a 
little before the middle of the wing, where it is deflected, and forms an 
oblique posteriorly-angulated fascia; near the inner margin at the base 
is another short golden-brown streak; in the apex of the wing is a 
small black spot; cilia white, but round the apical black spot they are 
golden, with the tips dark fuseous. Posterior wings pale grey, with 
paler cilia. 
Unique in Mr. Weir’s collection; taken on a‘fence at Camber- 
well, in June, 1850. 
T am by no means certain that it should be referred to this 
genus, but the structure of the palpi, which remove it from H/a- 
chista, allow of its being placed in the genus Argyresthia, and the 
rough head may have been rendered invisible by the distorted 
mode in which the insect was pinned.
