240 - THE ENTOMOLOGIST. 
taken tolerably plentifully by fumigating. The larva feeds on 
Salia fusca, the dwarf sallow, poplar (Populus), Myrica Gale, &e. It 
has also occurred in Kent,—at Birch Wood and near Dover. Not- 
withstanding the opinions of several entomologists to the contrary, 
I am inclined to believe that P. Lipsiana is only a northern variety 
or local form of this insect, and hope very shortly the life-history 
of the two species—for so they must be at present considered— 
will be completely elucidated. 
P. mixtana, Hub.—'This species: may be looked for on moors 
and heathy places. The imago appears in September and 
October, and is more often met with in the spring, after 
hybernation. In-places where the heather is tall, and can easily 
be worked, fumigating should also be attempted for this insect. 
It has occurred at Wimbledon and Shirley Heath (Surrey) ;.in 
Sussex, at Lewes, and a single specimen is mentioned in the 
Rev. E. N. Bloomfield’s list of Hastings and neighbourhood. 
In Kent it is sure to be met with on the moorland to the west of 
Tunbridge Wells. 
P. comparana, Hub.—Generally distributed. 
P. Schalleriana, Linn.—Generally distributed. I have met 
with this insect very abundantly some seasons near Folkestone, 
and afew of the variety Latifasciana, Haw., have been taken in 
the same locality. It appears scarce at Hastings, but it will 
probably be found when worked for. 
P. Caledoniana, Bent. MS.—Occurs not uncommonly in the 
north of Kent, but is a scarce and local species in the South of 
England.. ; 
P. permutana, Dup.—Formerly used to occur commonly in 
Surrey, on Barnes Common, among Rosa spinosissima in — 
August and September, but I am not aware of any recent 
captures, and fear it is no longer to be met with in its old 
haunts; indeed I have been informed that its food-plant is’ 
getting very scarce, and there is some fear of Rosa spinosissima 
following the example of other botanical rarities on the Common, 
and disappearing altogether. 
P. variegana, Schiff.—Common everywhere. 
P. cristana, Fab.—Scarce and local. The imago appears 
from August till November, and hybernated specimens are 
occasionally met with in the spring.. The larva feeds in rolled- 
up leaves of hawthorn, usually preferring old and mossy trees.
