 ment Gazette of 17th February 1922. It is hoped that the introduction 

 of this beetle may thus be prevented.

The Noctuid, Ufens plicatus, Grt., has been found in abundance 

 on poplar trees in Alberta. The larvae feed on the bark. This 

 moth is heavily parasitised by Apanteles sp. and by Tachinid larvae. 

 The eggs are laid in the cracks of the bark ; all spht bark should 

 therefore be removed. The trees generally survive the presence of 

 the pest, but their appearance is spoiled, and the open wounds often 

 become filled with water and harbour many Dipterous larvae feeding 

 on the decaying matter. ]\Iature trees are apparenth' immune from 

 attack. 



Other insects occurring in the cracks in the bark included 

 Rhynchagrotis placida, Grt., and Catocala sp. ; the latter is also 

 parasitised by Apanteles sp.

A large consignment of the Chalcid, ProspaltcUa loiinsburyi, Berl. & 

 Paoli, has been brought from Madeira to Florence for the control of 

 Chrysoniphalus diciyospermi. 



Icerya [piirchasi] is said to be of practically no importance in Madeira 

 owing to the activities of Novins cardinalis.

The following solutions are advocated as sprays against the increasing 

 numbers of Icerya purchasi, 25 parts resin, 13 caustic soda, 5 fish oil 

 and 2-5 cresylol, or 35 parts resin, 25 carbonate of soda, 5 caustic soda 

 and 10 fish oil. 



For winter applications 2-3 per cent, solutions should be used, 

 but they must be made weaker for summer use if scorching occurs. 

 The soil around each tree should be sterilised by fire or watering with 

 insecticides.

Of some 190 species here recorded over 40 are of economic importance. 

 They include : — Episomns lacerta, F., widely distributed in the plains, 

 causing appreciable damage to field beans {DolicJws lahlab) and other 

 pulse crops during the cold weather, and also recorded on Erythrina, 

 and as defoliating teak and Dalhergia latifolia ; Myllocerus viridanus, F., 

 occurring on a variety of field crops and trees, including ground-nuts, 

 Seshania, jute, teak and guava ; M. sithfasciatus, Guer., defoliating 

 Solanum melongena in the plains, potato in the Nilgiris, and apple in 

 Bangalore ; M. dentifer, F., fairly well di iributed throughout South
