vetches with oats ; P. albipennis, Fall., on harvested hay ; Clilamydalus 

 pullus, Reut., on summer wheat, lucerne, and vetches with oats. 

 A large number of aphid colonies was observed on barley in June. 



Lepidoptera : Caterpillars of Agrotis sp. injured maize around the 

 edges of the fields. 



Coleoptera : Melanotus brunnipes, Germ., was found in large 

 numbers during June ; larvae resembling the larvae of Melanotus 

 were found on field potatoes, sugar-beet and maize and also on black 

 fallow fields ; Blitophaga undata, MlilL, injured wheat and barley ; 

 the larvae of this pest were observed on sugar-beet in May Both 

 the larvae and adults are found on all kinds of wild plants, having 

 also been taken on lucerne and wheat. Larvae of Lema tnehnopa, L., 

 were found on winter wheat, barley and oats. Both larvae and adults 

 of Otiorrhynchus ligustici, L., injured lucerne. Several species of 

 Sitones were observed on lucerne in large numbers. AnisopUa segetum, 

 Herbst, occurred in the middle of Jane on winter wheat. A. austriaca, 

 Herbst. was found rarely. A. cyathigera, Scop., was observed on 

 winter wheat. 



Diptera : Diplosis sp. was first noticed on 1st June and appeared in 

 great numbers on winter wheat, which had just started to blossom ; 

 during the mornings and in windy weather, the insects remain on the 

 roots of wheat, becoming more active with the approach of the evening ; 

 the larvae were found in ears of whiter wheat on the 24th June. 

 Oscinis sp. was found in large numbers during the whole summer, 

 several generations occurrmg on barley and oats ; no damage was 

 noticed, owuig to the insects ovipositing in summer on the secondary 

 stems and apparently not affecting the grain ; late sowings of barley 

 however occasionally exhibited injuries to the central shoots. 



Hymenoptera : Cephus pygmaeus, L., appeared after 21st May and 

 in ever increasing numbers till the end of June and beginnmg ^f July, 

 when they gradually diminished and disappeared on 16th July ; they 

 are apparently particularlv fond of Cruciferous plants. Oviposition 

 was first noticed on 24th May on winter-sown wheat ; evidently the 

 females prefer to oviposit on fully formed stems, as it was observed 

 that they did not touch summer-sown wheat and gradually passed 

 from the early to late-sown winter wheat ; they appeared on summer 

 wheat only on 11th June, when the latter produced ears. Winter 

 wheat injured by the larvae was observed iii the first half of July. 

 Trachelus tabidus, F., appeared later than the previous species and is 

 chiefly found therefore on summer-sown crops. A large number of 

 the parasites, CoUyria calcitrator, Grav., were found with both the 

 above species ; the parasites oviposit mostly in the evening.
