THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
A. hirticomis, 949. Oak? The male 
and the oviparous wingless female ? 
A. Aceris, 950. Maple. Various spe- 
cies. This insect is especially remarkable 
on account of the variety of form which 
it assumes. 
A. Acericola, 951. Sycamore. The 
male, the viviparous wingless female, and 
the oviparous wingless female? This 
species may be a periodical variety of 
A. Aceris. I have only observed it in 
England ou one occasion, during a season 
remarkable for the profusion of Aphides 
which then occurred. It is very abun- 
dant in Sw'itzerlaud. 
A. Populea, 951. Lombardy, poplar, 
willow ; various species. The male and 
the oviparous wingless female? 
A. Salicis, 951. Willow. The male, 
the viviparous wingless female, and the 
oviparous wingless female ? 
A. Salicivora, 952. Willow. Always 
wingless ? 
A. Glycerice, 953. Floating grass (Gly- 
ceria jluitans ), also other grasses, See., 
such as Poa annua, Phalaris arundi- 
nacea and Juncus lampocarpus. The 
group to which Aphis Glycerice be- 
longs probably contains several other 
species, feeding on grasses, and yet un- 
described. 
A. litloralis, 953. Sea-shore grass. 
Always wingless? 
A. hirtellus, 953. Grasses. Always 
wingless ? 
A. Cyperi, 953. Rushes. ’The male 
and the oviparous wingless female? 
A. Eriophori, 953. tlare’s-tail cotton- 
grass ( Eriophorum vayinatum). The 
male, the viviparous winged female and 
the oviparous wingless female? 
A. bufo, 954. Sand-reed ( Carex are- 
naria) and small bugloss (Lvcopsis ar- 
vensis). Always wingless? Inis species 
has a very peculiar structure, and forms 
a distinct group in the genus. 
A. Picece, 954. Silver fir and spruce 
fir. The male, the oviparous female and 
the viviparous wingless female? This 
Aphis is not of constant occurrence, like 
several of the following species, but 
appears and disappears suddenly ; it 
especially inhabits arctic and alpine 
regions. 
A. Pini, 955. Scotch pine. The male 
and the oviparous female? 
A. Pinicola, 955. Scotch pine. The 
male and the oviparous female? 
A. Pineti, 956. Scotch pine. The 
male and the oviparous female? 
A. Abietis, 956. Spruce fir. The ovi- 
parous female? 
A. costata, 957. Scotch pine, spruce 
fir and other species. The male ? 
A. Laricis, 957. Larch. The male? 
A. Juniperi, 958. Juniper. The male 
and the oviparous female. 
A. submacula, 958. The male, the 
oviparous female and the viviparous 
wingless female? Food-plant? Only 
two specimens recorded ; one found in 
the Isle of Portland by Mr. Dale; the 
other taken at Interlacken, in Switzer- 
land. 
A. saligna, 959. Willow shoots. The 
male and the oviparous female? 
A. Roboris, 959. Oak twigs. The 
male ? 
A. ayilis, 960. Scotch pine and 
juniper. The male and the oviparous 
female ? 
A. Quercus, 962. Oak ; in the crevices 
of the bark of full-grown trees. This 
species is very remarkable, on account of 
the especial adaptation of its long pro- 
boscis to the structure of the oak bark, 
and on account of the capacity which it 
possesses of retracting its proboscis iuto 
its body. Dulwich, Epping, Weybridge 
and Guildford are as yet the only lo- 
calities in which it has been discovered. 
The winged female is of very rare occur- 
rence, and thus it is very seldom enabled 
to migrate, and never occurs in tbe 
abundant swarms which are charac- 
teristic of many other species of Aphis.
