Bactra stagnicolana Zell. (= siccella Walk.). 
After examining very carefully about fifty specimens from various 
sources and localities, I conclude they are all one species, to which Zeller’s 
name is applicable. Very variable in colour and intensity, hindwings 
varying from grey to white in both sexes (though usually grey in <£, whitish 
in $) ; a longitudinal stripe is often present in forewings, but not a trans- 
verse fascia ; structure constant, though shape of forewings varies very 
slightly.

<£. 15-17 mm. Head and thorax dark fuscous mixed or spotted 
with pale greyish-ochreous. Palpi pale ochreous sprinkled and spotted 
with dark fuscous. Antennal ciliations Abdomen grey. Forewings
