proving the most efficacious and economical. In other cases the 

 locusts were driven into corrals constructed of low iron fencing and 

 were then burnt or treated with some insecticide. 



The reports of the inspectors in the various districts are appended, 

 ^\'ith details of the measures adopted, which varied according to the 

 conditions in the different localities.

 mentioned in Mr. Alfieri's List. (Bull. 1916, 3. 1917.)— Bull. Soc. 

 Entom. d'Egypte, Cairo, x, no. 3, July-September, 1917, 

 pp. 96-97. [Received 22nd October 1918.] 



As regards the Cerambycids mentioned by Alfieri [see this Revieiv, 

 Ser. A, V, p. 293], Macrotoma palmata, F., should be noted as feeding 

 upon Eucahjptus and not camphor, which is very rare in the neighbour- 

 hood of Cairo. Dichostates subocellatus, Fairm., is found in the trunks 

 and branches of Poinciana regia. The larvae of Pseudoalbana lameerei, 

 Pic, have been observed attacking the stems of Citrullus vulgaris var. 

 colocynthoides in Nubia at the end of March. Adults emerged in the 

 middle of April. In the fruit of the same plant were found large 

 numbers of Baris gramdipenni.'i, which has hitherto been recorded in 

 EgN'pt only in the fruit of Citrullus colonjnthis.

The increase of Pectinophora (Gelechia) gossypiella (pink bollworm) 

 on Egyptian cotton has been ascribed to a growing degeneracy in the 

 cotton plants that has rendered them more hable to insect attack, 

 Investigations carried on for several years have however led to the 

 conclusion that no type of cotton at present grown in Egypt, whether 

 old or new, pure or impure, offers any specific resistance to the attacks 

 of the pink bollworm. It is known that in India P. gossypiella is an 

 enemy of secondary importance to cotton. But whenever an attempt 

 has been made to introduce the Egyptian varieties these have been 

 heavily attacked, while the Indian varieties cultivated in the vicinity 

 have scarcely suffered at all. It is obvious then that a selection 

 based on the question of immunity to pink bollworm attack would be 

 a distinct advantage in the planting of cotton. This is a recognised 

 method of control in dealing with certain vegetable pests and it is 

 hoped that by patient and intelligent experiment on the part of experts 

 the problem of the control of P. gossypiella may some day be solved 

 by this method.
