necessary modifications. An explanation of entomological termino- 

 logy is included, and each volume will contain an index to its contents, 

 an alphabetical index of the sections, famihes, subfamiHes and genera, 

 and a systematic index. A feature of the volume is a series of excellent 

 figures, illustrating the general characters and types of the families 

 dealt with. Where possible, a few interesting notes on the biology 

 of the family or group are attached. A bibliographical index is also 

 appended.

The need for a mycological and phytopathological centre has long 

 been felt in Russia. It is therefore suggested that a section or depart- 

 ment of mycology and ph3'topatholog3^ in connection with the Russian 

 Botanical Society should be established.

One of the initial questions to be discussed at the second meeting 

 of the All-Russian Entomo-Phytopathologists included the problems 

 of existing and future entomological stations. A general programme 

 of work for such stations is outlined by N. M. Kulagin, and a brief 

 account of the work of the Ivano-Voznesensky station is given by 

 A. N. Kazansky. 



The following pests for the summer of 1920 were recorded : — 

 Anthonomiis pomonim, L., Psylla mali, Forst., and Cydta pomonella, L., 

 on apples ; and Emphytus grossidariae, L., on currants and gooseberries, 

 three generations of this sawfly having occurred. Cabbages were 

 seriously injured by Pieris brassicae, L. The second brood was much 

 reduced by parasites, but the numbers increased again in the third 

 and a partial fourth was produced, which is unusual under existing 

 climatic conditions. Flea-beetles caused serious damage to radishes, 

 rape and turnips. Other cabbage pests were Brevicoryne brassicae, L., 

 and Phorbia brassicae, Bch. Adults of Loxostege sticticalis, L., were 

 unexpectedly abundant, but the larvae confined their attention to 

 weeds. Forficula aiiricidaria caused serious injury to the foliage of 

 beet, and even of potatoes. Homoeosoma nebidella, Hb., was also 

 abundant. 



The pests of field crops included the Hessian fly [Mayeliola destructor] , 

 frit fly [Oscinella frit] and Chlorops taeniopus, Meig. Potatoes were 

 seriously injured by wire- worms.
