INSECTS INJURIOUS TO THE VINE. 323 



came, as is alleged, from Senegal, it is not amongst the number 

 of those designated by the ancients ; who indeed could hardly 

 have distinguished the different species of Coccus, since, al- 

 though M. Fonscolombe's beautiful work on these insects had 

 appeared, it required all the assistance that the most practised 

 eye, with the help of glasses of high magnifying power, could 

 give, to enable a modern entomologist to ascertain the dis- 

 tinction. 



M. Fonscolombe has well remarked that no good limits 

 have been drawn between the Kermes and the Cochineal 

 insects, between the Gallmsecta and the ProgaUinsecta of 

 Reaumur. This accomplished naturalist has therefore adopted 

 the plan of making only one genus of Coccus and Chermes; but 

 he subdivides this genus into many sections, and the Coccus of 

 the vine' belongs to the section composed of species having the 

 body naked, without any trace of rings or limbs at the period 

 of laying the egg, during which time they remain on the nest, 

 which looks as if it were made of cotton. 



The Coccus Adonidum, or Hothouse Kermes, is also remark- 

 able for the white cottony substance it exudes, which gives it 

 the appearance of being covered with flour. 



The word Phteire, given to one of the Gallinsecta by the 

 author of the Geoponicks, is connected with the interpretation 

 of the word Thola, Tholea or Tholaath in the Bible ; which 

 subject claimed our attention at the commencement of these 

 Researches. 



It will be remembered that the result of our long discussion 

 respecting it was, that Thola was employed in the Bible not 

 only to signify a worm, vermin, an insect, or the larva of an 

 insect, or an animal vile and contemptible, but also an insect, 

 or the larva of an insect, which ate the vine, and another plant 

 of whose name we are ignorant, but which was of some size, 

 since it was capable of affording considerable shade: indications 

 so vague would scarcely enable us to form a probable con- 

 jecture concerning it, if the word, which only occurs in the 

 Bible, had not been several times used there joined to the 



on the Insects most prevalent on fruit trees and garden produce, 1829, in 8vo. p. 144, 

 the Mealy Bug.
