8 THE ENTOMOLOGIST. 
and Athous undulatus have either been beaten from dry fir tops 
or found on or in fir-stumps, or in some way or other connected 
with the tree. 
The elm has produced Brontes deplanatus (taken in some 
numbers by Mr. Rye near Richmond), Jschnodes sanguinicollis 
(taken in abundance by Dr. Power at Esher), Oxylemus 
variolosus, Trichonyx sulcicollis, Quedius truncicola, Euryusa 
laticollis, Megapenthes lugens, and tibialis. This latter beetle 
has occurred to Dr. Power in beech at Burnham Beeches ; the 
beech has also produced Orchesia undulata, Synchita medio- 
lanensis, and on one occasion a specimen of Colydiwm elongatum 
(far removed from Platypus). 
The oak harbours many good species, especially Elateride 
and Buprestide. Dr. Power has kindly given me the following 
notes from his own experience :—‘' Elater lythropterus, E. san- 
guineus, E. pomone, oak-stump ; Elater rujitarsis, inner side of 
wood of hollow oaks at Windsor; Ludius ferrugineus, a number 
of beetles and larve inside a hollow oak in Windsor Forest : 
this beetle has also been taken inside a hollow walnut at Swaff- 
ham, Cambridge; Anthaxia nitidula feeds inside hollow wood of 
old oak, New Forest ; Agrilus biguttatus, between wood and bark 
of oak : it goes to pupa in the bark and comes out in the second 
year after cutting.” Besides Elateride, good species like 
Limexylon navale, Abdera quadri- and bi-fasciata, Pediacus dermes- 
toides, Dorcatoma, Batrisus, Quedius scitus, and Q. chrysurus, and 
many others, have been taken from the oak. <Agrilus sinuatus 
has been found in whitethorn under the same circumstances as 
A. biguttatus in oak. 
The apple and pear have produced Scolytus prunt, and other 
species of the same class, Dromius 4-signatus, Haploenemi, &e. 
Willows occasionally harbour a good species abundantly, as 
Lamia textor, taken near Bristol ; Choragus sheppardi, taken under 
bark of loose willows near Newark by Mr. Hadfield. Hallomenus 
has also occurred in this tree, but its food is fungus. 
The birch seems especially attractive to Hros, both FE. minutus 
and EF. ajinis having been taken under its bark. Several good 
Elaters, and beetles such as Homalium inflatum, Rhopalodontus 
perforatus, Epurea immunda, &e., seem partial to this tree. 
We may perhaps, in passing, mention Agathidium nigripenne, 
Opilo mollis, and Ptenidiwn turgidum, from ash; Lemophleus
