Poedisca ? rujimitrana, H.-S. — I had the pleasure of making the 

 acquaintance of this species iu the living state at Merton, under the 

 guidance of Mr. Hartley Durrant. I was late for it — the beginning 

 of August — and it was getting worn, but we obtained several good 

 specimens from trees of Abies cephalonica. It seems to be principally 

 attached to this handsome fir, which grows in plenty, and in great 

 vigour and beauty at Merton Hall. 



Mixodia Ratzehurghiana, E,tz. — This species was not uncommon 

 at the same time and place, but occurred only among Pinus sylvestris. 

 Subsequently a single specimen turned up near Lynn, where it had 

 not previously been observed. 



Mixodia rubiginosana, H.-S. — This species also occurred near 

 Lynn, in June : half a dozen specimens being beaten out of one or 

 two young trees of Pinus sylvestris. None could be found except in 

 these trees, although the fir was plentiful around. Probably these 

 were all produced from the eggs of a wandering female in the previous 

 year, for this was its first occurrence in the locality, although single 

 specimens have been taken in several previous years, within a few 

 miles, by Mr. Atmore. It is most interesting to notice the gradual 

 spread of this species {Bouchardana, Dbl.) over the country. Eor- 

 merly, it was only taken in the highlands of Perthshire, and was there 

 a great rarity ; after a time it was found more commonly near Paisley ; 

 more recently it has occurred somewhere in the London district 

 (although the locality is very naturally kept a profound secret by the 

 captors), and this year it occurred near Thetford, as well as here. 

 Doubtless, it is sometimes introduced with young trees from Scotland, 

 but it takes kindly to inadvertent acclimatisation, and will probably 

 be known in time wherever Scotch fir grows in plenty. 



Plioxopteryx diminutana, Hw. — This graceful species has been 

 rather commoner than usual, always about sallow bushes in marshy 

 places, but sluggish and hai'd to take, except at sunset, when it flies. 

 In the day-time it darts to the ground when disturbed, and is generally 

 secure from capture ; but my friend Mr. Atmore circumvented some 

 of them even then, for they could not endure his tobacco smoke. 



Plioxopteryx uticana, Hiib. — Most abundant on a marshy heath, 

 and interesting from the beauty and size of many of the specimens. 



Phoxopteryx biarcuana, Stph., and inornatana, H.-S. {subarcuana, 

 Dougl.). — Both more than usually plentiful among Salixfusca, and 

 the former species very fine and handsome, Of the latter I noticed 

 a second brood in Aucust.
