Head saftVon-yellow, moi'c. or less mixed with brownish. Pace and 

 palpi white. Antennas whitish, with darker annulatious, before the 

 apex white. Hinder tarsi whitish, sometimes spotted pale fuscous. 

 Anterior wings sJibi'uig pule saffron-gellojo, or oclireons-brown, with a 

 veri/ decider, unmarg'uted, white or whitish basal streak ; on the inner 

 margin near the base is an Incompicuous white spot or streak, ichlch 

 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. 



Tliis species is susceptible of considerable variation ; it is com-

 Head saffron-yellow, mixed with brownish. Pace and palpi 

 whitish. Antenna? whitish, with darker annulatious, the apex white. 

 Anterior wings dull ocJtreous-brown, with a very slender, tiniiiargined, 

 white basal streak ; on the inner margin near the base is an unmar- 

 giued wliite triangle, the apex of ivhich 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 tlie apex is an ovate black spot. Posterior wings grey, with paler cilia. 

 I bred many hundreds of tins from larv^ic mining in the under- 

 side of the leaves of the osier m 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.
