The cotton boll worm [Heliothis obsoleta) has of late years done 

 great damage to cotton plantations in the governments of EHsavetpol, 

 Baku and Tiflis ; in 1914 and 1915 it was responsible for a decrease 

 in the harvest of 25-30 or even 50 per cent.

 The budget of the Don Bureau for the control of pests during 

 1915-16 amounted to about £900 assigned by the Department of 

 Agriculture and over £700 assigned by the Provincial Military 

 Authority. In 1917 the expenses are estimated to exceed £3,000, 

 about half of which sum is to cover the salaries of the staff of the 

 Entomological and Phytopathological Sections of the Bureau. E. V. 

 Zvierezomb-Zubrovsky has been appointed Director of the Entomo- 

 logical Section and Miss A. V. Shamrai his assistant. A discussion 

 on the objects and work of the new Bureau resulted in a decision 

 to allow the staff a free hand in deciding the scope of their work.

Trichogramma fasciatum.. Perk., is seldom found in orchards in 

 the Crimea ; of 50 eggs of Cydia fomoneUa collected in 1912 

 none were infested with this parasite, while in 1913 only 2 per 

 cent, proved to be infested. T. semblidis, Aur., is more common and 

 in 1914 this parasite infested a considerable number of eggs of 

 Barathra {Mamestra) brassicae. The experiments on the artificial 

 rearing of these parasites in the laboratory were begim. on the eggs 

 of Cydia pomonella, but owing to the limited number of these which 

 were available, it was found necessary to make use of the eggs of 

 many other Lepidoptera, as well as eggs removed artificially from 

 the ovaries, before oviposition, which also proved quite suitable. 

 Female butterflies and moths caught on fermenting molasses were 

 kept in small glasses, the inside of which was lined with paper, placed 

 upside down on a piece of paper. The eggs were transferred, by 

 cutting out small pieces of the paper on which they were deposited 

 to small test-tubes ; from 3 to 10 eggs were placed in each tube 

 together with one or two parasites, as it was discovered that the 

 latter live longer if kept isolated. As the numbers of insects caught
