present similar varieties. The sexes will also pair indiscrimi- 
nately. ; 
S. lariciana, Zell.—Local among larch (Larix europea), but 
generally abundant where it occurs. It is as variable as the 
preceding in colour and markings, but may readily be distinguished 
from it by having much narrower wings. The moth may be 
taken commonly in June and July flying at dusk round the 
larches, but as it usually keeps about ten or twelve feet high up 
the tree, a long net is very handy when after this species. 
S. aceriana, Dup.— Not uncommon among black poplar. 
(Populus nigra), and more sparingly among aspen (P. tremula). 
Last year I noticed, adhering to the shoots and leaf-stems of the 
large-leaved balsam poplar, close to London, some curved case-like 
appearances, which at first sight I took for the cases of a Coleophora 
larvee. On examination, however, they turned out to be com- 
posed of stout whitish silk with the outside covered with frass. 
On detaching some from the twigs I found each covered a small 
hole in the stem, in which a larva was feeding. I kept several of 
the shoots in water, and reared a series of this insect, the 
transformations from larva to imago occurring generally within 
the shoots, which did not appear materially injured by their 
_ presence. 
S. pauperana, Dup.—The old locality for this insect, given by 
Stainton in his ‘Manual,’ was “ hedges and lanes near Darenth 
Wood,” but, though frequently worked for, this species is now very 
scarce there. I met with a single specimen flying slowly in 
the sunshine over wild rose bushes in Surrey, in 1877, as far as I 
am aware the first occurrence of this species in that county. I 
do not know of any captures in Sussex. 
S. dealbana, Fr6l.—A variable species, and specially abundant 
in woods and woody lanes. 
S. neglectana, Dup.—Local, but generally abundant where it 
occurs. It is usually to be found on the trunks of large sallow, 
and sometimes poplar, trees; and occurs freely at Camberwell, 
Hammersmith along the banks of the river, Surbiton, and similar 
localities. It may easily be distinguished from S. dealbana by the 
bluish black markings which in that species are of a reddish 
brown. ‘This is also rather a larger insect, and does not vary. 
S. simplana, F. v. R.—Very local among aspen (P. tremula). 
Darenth Wood used to be its chief locality, but the part of the
