Burying young cuttings ; L. Lichtenstein, Bull. Soc. Var, (7) i. No. 3. 
The same author, Bull. Soc. Ent. Fr. (5) iii. p. xiii., recommends planting 
young cuttings or shoots of vine round the infected plants ; these 
attract the insect and can be pulled up and burned in May or June. Sur-

The second year of attack by the insect is the most fitting to 
attempt its destruction ; Bertrand, op. cit. Ixxvii. p. 871. 
The spring is the best time for using destructive agents ; M. Cornu, 
op. cit. p. 947 (but see Faucon, supra). 
Phylloxera querciis. Balbiani, C.R. Ixxvii. pp. 830-834, 884-890, gives 
particulars of the economy of this species, and of the structure of its 
reproductive organs. Parthenogenesis occurs in it. There are 3 sorts of 
eggs: — the winter, summer or parthenogenetic, and male and female 
(dioiques). Derbes, op. cit. pp. 1109 & 1110, compares the Pemphigus 
found on Pistacia terebinthus with the Phylloxera. Cf. also Milne- 
Edwards, p. 1111. Balbiani, op. cit. pp. 1164-1168, replies to Derbes: 
P. quercus and vastatrix must be added to the limited number of species 
known to present Leuckhart's ' heterogonie.'
