BY WHICH THE VINE IS INFESTED. 215 
Our cultivators do not complain of these insects, and know but little of 
them, because the annual pruning which the vines undergo prevents 
their multiplication, as the Cocci can only live upon young wood, 
while its epidermis is still tender. They are however sometimes very 
‘abundant upon neglected vines ; and in countries where the vine is only 
cultivated in greenhouses, they multiply extremely, whilst the other 
enemies of the vine are there unknown*. But the vines in green- 
houses are not attacked by the same species of Cocci as they are ex- 
posed to in the open air. In the former situation they are attacked by the 
Coceus Adonidum+, not by the Coccus Vitis. If, as has been asserted, 
this insect originally came from Senegal, it is not among the species 
treated of by the ancients, who also could never have distinguished 
from each other the various species of the Coccus, which is as much as 
can be effected by the practised eye of the modern entomologist, aided 
by a powerful lens, even since the beautiful and recent work of 
M. Boyer de Fonscolombe upon these insects. This skilful naturalist 
remarks with truth that there are no well-established limits between 
the Kermes and the Cocci, between the Gall-insect and the Progall- 
insects of Réaumur. He therefore makes but one genus of the Coccus 
and the Kermes; but this he subdivides into several sections, and the 
Coccus of the vinet belongs to the section which is composed of spe- 
cies which at the time of laying have naked bodies, without any trace 
of rings or members, and rest upon a very cottony nest. The Coccus 
Adonidum, or Kermes of the greenhouse, is also remarkable for the 
white and downy substanee which transudes through its skin, and 
which gives it a mealy aspect. 
The interpretation of the word Thola, Tholea, or Tholaath employed 
in the Bible, which we considered at the commencement of these re- 
searches, applies to the name Phtheir given to the Gall-insect by the 
author of the Geoponies. It will be recollected that the result of our 
long discussion upon this subject was, that Thola is employed in the 
Bible to signify not only a worm, vermin, an insect or larva of an insect, 
or an animal vile and despicable, but also an insect or larva of an in- 
sect which infested the vine, and another plant, the name of which we 
are unacquainted with, but which we know to have been a large tree, 
because it gave an extensive shade. Indications so vague would not
