in 3 gals, water, it gave on the first day a death-rate of 10 per cent, of 

 caterpillars of nettle moth, rising gradually to 100 per cent, in five 

 days, whilst, at double strength, the death-rate on the first day was 

 100 per cent. The budget of the Station in 1913 amounted to £1,186, 

 of which £1,030 were contributed by the Department of Agriculture.

The information contained in this Review has been compiled from 

 replies to a circular letter sent out during the first half of 1914 by the 

 Ural Society of Friends of Natural Science, the rephes covering many 

 localities in the governments of Orenburg, Perm, Ufa, Vjatka, and 

 the province of Turgai. Acridiidae were reported from nearly all 

 the governments ; they are a serious danger in Orenburg and 

 Turgai, much damage having been done by them in both areas. 



Mayeiioh {Cecidomyia) destructor, Sa}^ is recorded from Ufa and 

 Perm, where it appears to attack rye in spring, the pupae being found 

 in autumn in the leaf-sheaths and the imagines hatching out at harvest 

 time. Oscinella [Osciyiis) frit, L., causes serious damage in many 

 places, probably in company with Chaetocnema aridula, Gyl., in Ufa. 

 Euxoa {Agroiis) segetum, SchifE., is widely spread; the caterpillars 

 do great damage to }'oung rye, and in August, September and even 

 later in warm weather, they injure winter crops. The protection 

 of the natural enemies of these pests is suggested, such as Carahus 

 nemoralis, Miill., C. ccmcellatus, F., C. gramdatus, L., and Tachinidae. 

 The other pests of field crops reported, are : Sitones Imeatus, L., 

 probably also Sitones crinitus, 01. and S. sulcifrons, Thunb., and 

 Macrosiphum {Siphonophora.) pisi, Kalt. Forest pests included : 

 Hylohius abietis, L., Meloloutha hippocastani, F., the Longicorn, 

 Acanthocinus aedilis, L., and Scolytidae ; the moths, Cossus cossus 

 (ligniperda), Malacosoma {Lasiocampa) neustria, Dendrolimus {Gastro- 

 paclm) pini, L., Lymantria (Ocneria,) dispar, L., L. monacha, L., 

 Bupalus piniarius, L., and Panolis piniperda, Panz., Hyponojneuta 

 padi, Zett., and the sawfly, LopJiT/ras pini, L. Gryllotalpa gryllotalpa, 

 L., injured 13 acres of forest in the district of Ekaterinburg. 

 Orchards in some localities of the government of Orenburg have 

 suffered from Aporia crataegi, L.

An account of the work done by the Station during 1914 is given 

 with reference to studies on insect pests and experiments with insec- 

 ticides, etc. A list of insect pests noticed during the year includes : —
