APHIDIDJE.
WALKER, Zool. s. s. pp. 1048-1053, 1118-1123, 1296-1301, 1328-1333
(1868), 1996-2001 (1870), in this paper gives a translation of Passerini's
work, in which the Aphididae are divided into 6 tribes, and adds notes of
his own on many species belonging to the various genera.
Phylloxera vastatrix (Planchon). Targioni-Tozzetti, Bull. Ent. Ital.
pp. 68-76, treats at some length on the development and habits of this insect,
and illustrates his paper with drawings of the creature in various stages of development.
Under the title " Entomologia Agraria,' /. c. pp. 202-206, there
is a further reference to this genus.
Phylloxera. Lichtenstein (Ann. Soc. Ent. Fr. (4) x. Bull. p. x) gives
an account of his observations made during a journey with Planchon to
vineyards infested by this insect. He advocates the use of bisulphuret of
calcium for their destruction, and believes the insect attacks the healthy
vines, a belief which is not shared in by either Signoret or Guerin-Meheville.
