ON THE TYPE OF THE GENUS COCCUS, L
Published online by Cambridge University Press: 31 May 2012
Extract
The first attempt to separate the species given under Coccus in the 10th edition of the Systema Naturæ of Linneus, was made by Geoffroy, in his Histoire Abregée des Insectes, Vol. 1. (1762), where he placed a part of them under Chermes and left adonidum and phalaridis, with his new species ulmi, under Coccus. Of these species only phalaridis was given under the genus Coccus by Linneus in his 10th edition, and is therefore the only species that could be regarded as the type of Coccus so far as Geoffroy is concerned.
