CATALOGUE OF MOTHS. 295 



Another common species, and generally plentiful. Meyrick 

 gives it as identical with Russata, but everyone else recognises 

 them as distinct. In all our local lists. My experience of the 

 two is that Russata is always common in lanes, Immanata 

 never occurs out of woods, and that Russata is always over 

 long before Immanata appears. Immanata too is always larger, 

 and varies on different lines, the form with red centre patch 

 for instance that is so common with Russata never appears in 

 Immanata.

Common everywhere, and in all the lists. The dark variety 

 Piceata also occurs in every part of our district, and is often

 to emerge.

Not a very common species, but generally distributed, and 

 no doubt occurring sparingly in all the larger woods and denes. 

 Mr. Bolam says — "Does not appear to be generally common, 

 but I have taken it at Marshall's Meadows, !N^ewham Bog, 

 Pen wick Wood, and near Ayton, from 25 th May till the middle 

 of July, no doubt double brooded " (Trans. Ber. P. Club, vol. 

 XV., p. 302). It is also in the Twizell list; Mr. Pinlay found 

 it in all the woods he collected in, but it was never common • 

 Mr. Maling took it near Hexham ; and Newcastle is a Manual 

 locality. Mr. Hedworth found it in the Thornley woods, but
