The increasing cultivation of cotton in Turkey favours the intro- 

 duction of pests of this plant, and a list is here given of those that 

 occur in Egypt, including Prodenia litura, Earias insulana, PectinopJiora 

 {Gelechia) gossypiella, and the less important Schistocerca peregrina, 

 Oxycarenus hyalinipennis and Aphis gossypii.

An example of the successful control of Aulacaspis pentagorm^y 

 means of Prospaltella berlesei is recorded, the procedure adopted 

 having been already described [see this Review, Ser. A, ii, p. 526].

The conclusions reached are that weather has no influence on 

 Eriocampoides limacina, Typhhcyha rosae, Tetraneura ulmi and 

 Eriophyes similis. Winter cold was injurious to Lyonetia clerkella, 

 Coptodisca splendoriferella, Phytomyza vitalbae, Neuroterus quercus- 

 baccarum, Pontania femoralis, Ceuthorrhynchus sulcicollis, Eriophyes 

 pyri, E. vitis, E. tiliae var. liosoma, E. pseudoplatani, and E. tristriatus 

 var. erineus.^^ The dry and warm summer of 1917 favoured Tetranychus 

 telarius.

 that two generations occur, the first in May and the second in
