the middle of the month, and by the 22nd of July the alate forms were 

 seen. These were both male "and female. This is apparently the 

 first record so far of an oviparous winged Aphid. Although mating 

 was not actually observed, there is no doubt, owing to the anatomical 

 structure of the insects, that the winged female is fertihsed by the 

 winged male.

The history of the inauguration of a special entomological depart- 

 ment attached to the Nikolaevsk experiment station is briefly reviewed. 

 In 1916 L. I. Bogdanova-Katkova was appointed to undertake system- 

 atic observations on the Halticinae and Dipterous enemies of 

 graminaceous crops in the neighbourhood of the station.

During 1916 insect pests were comparatively scarce. The most 

 serious cabbage pest was Phorbia {Chortophila) brassicae, Bch., adults 

 of which were seen in abundance on 10th May. The eggs were found 

 on 17th May on the stem immediately above the ground and more 

 frequently in the ground in the vicinity of the roots. The chief 

 methods of eradicating this fly are the scraping of eggs from the stems 

 and the application of saltpetre or ammonium sulphate to the sur- 

 rounding soil. The plant is thus strengthened and becomes more 

 resistant to attack. Other vegetable pests dealt with during the year 

 are Eurydema oleraceum, L., and E. dominidus, Scop., the larvae of 

 which were numerousinjuneand July on weeds; and Br evicoryne {Aphis) 

 brassicae, L., on cabbage, beetroot, Raphanus raphanistrum and Capsella 

 bursa-pastoris. Syrphus ribesii. L., S. balteatus, DeG., and other Syrphids 

 were generally found in kitchen gardens where Brevicoryne brassicae was 

 numerous. Pieris brassicae, L., P. rapae, L., and P. napi, L., were not 

 very abundant, probably owing to tl^e activity of parasites. Barathra 

 {Mamcstra) brassicae. L., Polia {M.) pisi, L., and Plntella maculipennis. 

 Curt., occurred on cabbages. Meligethes aeneus, ¥., is chiefly a pest 

 of cruciferous plants grown for seed, but was also found on Ranun- 

 culaceae. It was associated with Malachius aeneus, L. Aihotis mger, 

 L., Agriotes lineatus, L., and A.obscurus, L., were particularly abundant
