This moth is abundant everywhere, and diifers from the e(piall\' common 

 O. di'.vgtiata in the pectinated anteniue, very broad, black, or dark brick- 

 red nnddle band, bordered on each side with li^ht-reddish waw lines. The 

 l)lack variety seems to be as abundant as the red. more t\|)ical f()rm. It 

 seems to lie less expo.sed to variation than in (). designata. 'I'lie black or red 

 band varices much in width, ;nid the discal dot in distinctness. In some speci- 

 mens, the median band is of a rich wine-brown hue. In some examples, tin- 

 median band is centered by a row of dark oval spots Our brown examples, 

 on comparison with one example Irom North Germany, received I'ron) Pro- 

 fessor Zeller, do not sliow any differences. Our l)lack variety seems to be 

 identical with Hawortli's unidentaria, common in Kngland. Stainton retains 

 this as a distinct species from fcn-iigaria, though he slates that "the larva is 

 nndi.stinguishable" from \\v,\i {A' ferrugaiia. Staudinger also icirards it as a 

 distinct species, stating that it occurs in England, Northern (iermany. and, 

 doubtfully, in Finland and Livland I am incdined to reuard it onlv as a
