caterpillars pupate in the earth, within a radius of about 15 inches 

 round the base of the trunk, and may be destroyed by hoeing the 

 soil in these spots.

While removing trees in the environs of Askhabad in 1911, the 

 author observed that larvae of cockchafers collect among the rotten 

 roots of the silver poplar {Populus hybrida). He therefore made 

 experiments to find out whether, in the presence of these trees, the 

 larvae would leave imtouched the roots of others. In the spring of 

 1912 he therefore placed in the soil in a vertical position pieces of 

 poplar about 14 inches long ; in the following spring enormous numbers 

 of the larvae were collected under these, while some roses near by were 

 quite uninjured. Experiments repeated during the three following 

 years confirmed the fact that cockchafer larvae prefer poplar trees 

 to any other and this method has been adopted w^th success when 

 planting some 50 fruit-trees in the nursery of Askhabad. A note by 

 the Editor of this Journal regrets that the species of cockchafer tested 

 is not given ; it is, however, stated not to have been Melolontha 

 tnelolontha {vulgaris).

A sum of £750 was assigned in April 1916 by the Local Authority 

 of Turkestan to enable Mr. A. V. Gratchev, Assistant Director of the 

 Turkestan Agricultural Station, to organise experiments on the 

 control of locusts by means of Coccobacillus acridiorum ; the work 

 will be carried out at the Entomological Station of Turkestan.

Large outbreaks of the gipsy moth [Lymantria dispar] occurred 

 during 1915 and 1916 in AuHeata and it is expected that this will be 

 the case again in 1917, as, in the absence of any artificial means of 

 control, it takes three years for the natural parasites of this pest 

 to check its development.
