cheap as the cochineal; and, therefore, only very small quantities of it are 
brought to market. This species is not unfrequent in British collections, 
where, however, it is somewhat tender, and of very slow growth. It is 
propagated from the acorns, which are received from the Continental nur- 
serymen ; and small plants, in pots, are from Is. 6d. to 3s. 6d. each. 
The Kermes. The specific name of coccifera has been applied to this species 
in consequence of its affording nourishment to a species of Céccus, or scale 
insect (Coccus flicis Lin, Syst. Nat., 2740., No. 6.); though the student of the 
Systema Nature will at once perceive the impropriety of the Linnzan applica- 
tion of these names, Coccus and Chérmes, the latter being applied to another 
totally distinct genus of minute homopterous insects allied to the plant lice, to 
which, from their saltatorial powers, Geoffroy gave the name of Psylla, with 
much greater propriety ; employing, however, both Céccus and Chérmes as 
generic names of insects belonging to the family Céccida. The insect in 
question is also known under its 
Arabian name, Chermes or Kermes ; 
Scharlachbeeren, Ger.; Grein Schar- 
lakbessen, Dutch; Grana Chermes, 
Cremese, or Cocchi, Jtal.; Grana 
Kermes, or Grana de la Coscoja, 
Span.; and Alkermes, Persian; 
and, previously to the discovery of 
the New World, was employed to a 
very great extent in dyeing, pro- 
ducing a very permanent and rich 
blood-red colour. It will be seen, 
from the accompanying figure (jig. 
1793.), that this parasitic insect has 
all the appearance of a berry or 
seed, affording not the slightest indi- 
cation of its insect nature; being 
immovably affixed in clusters to the 
branches of the oak, upon which it 
subsists, ‘by introducing into the 
substance of the stem.a long and delicate haustellum. It is only, however, at 
the close of its existence that it assumes the form of aseed. Mr. M‘Culloch 
indeed, states that it is in the process of drying that this form is acquired ; but 
this is not correct, since, although op muee) is provided with legs, and, when
