varieties used for chewing, the loss being 5 per cent., while in the case of 

 oil varieties, it was only from 1 to 2 per cent. In former years, this 

 pest has often totally destroyed the chewing varieties.

In both these districts, the greatest damage is done by a flea-beetle, 

 Haltica sp., a sawfly, Athalia spinarum, F., and a blister-beetle, 

 Ejpicauta sp., all of which chiefly attack mustard, while the last- 

 named during 1914 also injured tomatoes, potatoes and peas.

This is a series of reports of various sections, institutions, and 

 nstructors of the Society. An outbreak of the webworm Phlyctaenodes 

 sticticalis, occurred in 1912 in two districts, causing great damage 

 to field and bachza crops. The budget of the Entomological Station of 

 the Society, which has existed since 1911, was about £400, of which about 

 £200 constituted a government grant. The instructors of the Society 

 were chiefly instrumental in assisting the population in the control of 

 various pests. A. I. Kutin, the chief Instructor of the districts of 

 Astrachan and Krasnogarsk, mentions in his report that Cydia potno- 

 nella, in some localities, has destroyed nearly two-thirds of the yield 

 of the apple trees and that the caterpillars of Pohjchrosis botrana have 

 destroyed half the vintage in some vineyards. Other pests included 

 Rhynchites auratus on cherry trees ; Hyponoyneuta malinellus, 

 Euproctis chrysorrhoea, Psylla pyricola, Gryllotalpa gryllotalpa and 

 Polyphylla alba. Bachza plants have also suffered considerably from 

 a fungus [Orobanche ramosa) which, how^ever largely decreased towards 

 the end of summer, as it was fed upon by the larvae of a fly, Phytomyza 

 orobanchiae.

Near the village of Assovo, in the district of Kungur (government of 

 Perm), there are large groves of Prunus padus, L. (bird cherry), 

 which, in June 1914, were attacked by great swarms of the
