 The bulk of the information here given on Phaenacantha aiistralica, 

 Kirk., has already been noticed [R.A.E., A, ix, 9, 89]. Its natural 

 enemies also include a fungus. The eggs of the Reduviid, Pristhesancus 

 papttensis, which is predacious on P. australica, are deposited in 

 ■clusters on the leaves of sugar-cane, where a parasitic Chalcid, Anastatits 

 sp., is often found associated with them. 



Insects Injurious to Plant lAle.—Cyprus Agric. JL, Nicosia, xvi, 

 pt. 3, July 1921, pp. 53-54. [Received 31st October 1921.] 



Particulars are given of the results of the visit of Mr. G. Storey 

 to Cyprus to investigate the scale-insects, Aspidiotus hederae and 

 A . lataniae, which had been observed in Egypt on lemons and oranges 

 •coming from that island. A. hederae was not found at all in lemon- 

 growing districts, but was abundant on wattles, oleanders and other 

 shrubs, and occasionally on carobs. The species supposed to be 

 A. lataniae proved to be A. cydoniae, which is already known in Egypt. 

 The most injurious scale on Citrns in Cyprus is Chrysoniphalus {A.) 

 aurantii, which is also prevalent in Egypt. 



The ohve moth [Prays oleellus], ohve leaf -miner {Cecidomyia sp.) 

 and a scale-insect {Aspidiotus sp.) were abundant on olives in Cyprus. 

 These have not been recorded in Egypt, and may prove dangerous 

 if the importation of olive trees and green olives is allowed. The 

 leopard moth {Zeuzera pyrina) was abundant in the branches and 

 twigs of olives, pomegranates and Rosaceous plants, but it is also 

 •common in Egypt. The olive Psyllid [Enphyllura olivina] is abundant 

 on the trunks of olive and carob trees, which are not hkely to be 

 exported to Egypt.

The preparation of the more usual insecticides is described, and 

 formulae are given for kerosene-soap emulsion, tobacco extract, oil 

 and flour paste, lysol, creolin and lime-sulphur. Two methods of 

 preparing hydrocyanic acid gas for fumigation are also described,
