272 LITHOCOLLETIDA. 
tenuissima alba non obscure marginata, strigulis quatuor costs, tribus 
dorsi introrsum fusco-marginatis, albis albidisve, squamis sparsis nigris 
disci, puncto oyato apicis nigro. Exp. al. 33-45. 
Head saffron-yellow, more or less mixed with brownish. Face and 
palpi white. Antenne whitish, with darker annulations, before the 
apex white. Hinder tarsi whitish, sometimes spotted pale fuscous. 
Anterior wings shining pale saffron-yellow, or ochreous-brown, with a 
very slender, unmaryined, white or whitish basal streak; on the inner 
margin near the base is an inconspicuous white spot or streak, which 
does not reach the basal streak; on the costa are four and on the inner 
margin are three white or whitish streaks, all are dark-margined to- 
wards the base of the wing; the first pair of spots frequently unite and 
form an angulated fascia; between these and the third pair of spots 
are numerous black scales on the disc; at the apex is an ovate, rarely 
streak-formed black spot. Posterior wings pale grey, with ochreous- 
grey cilia. 
This species is susceptible of considerable variation ; it is com- 
mon in May and August. ‘The larva mines the underside of the 
leaves of the sad/ow in autumn and July. 
15. viminetorum, n. sp. Alis anticis ochrco-brunneis, linea ba- 
sali tenuissima alba, non obscure marginata, cum apice trianguli dorsalis 
albi (non obscure marginati) confluente, fascia angulata in medio, stri- 
gulis tribus cost, duabus dorsi albis, puncto ovato apicis nigro. Exp. 
al. 33-4 lin. . 
Head saffron-yellow, mixed with brownish. Face and_ palpi 
whitish. Antenne whitish, with darker annulatioris, the apex white. 
Anterior wings dull ochreous-brown, with a very slender, unmargined, 
white basal streak; on the inner margin near the base is an unmar- 
gined white triangle, the apex of which reaches to the basal streak ; in 
the middle is an angulated white fascia, slightly margined with dark 
scales internally ; beyond are three costal and two dorsal white streaks, 
the first pair of which only are distinct, and internally dark-margined ; 
at the apex is an ovate black spot. Posterior wings grey, with paler cilia. 
I bred many hundreds of this from larvee mining in the under- 
side of the leaves of the osier in autumn; all the specimens thus 
bred, though showing some slight variation, are constant in their 
differences from the preceding, and I cannot but think it speci- 
fically distinct.
