half of August on oaks and on Corylus, but no serious damage was 

 done. Colaspidema {Colaphus) hoefti, Men., together with Phyllotreta 

 sp., have done great damage to mustard ; the breeding of C. hoefti 

 is favoured by the abundance of wild Cruciferae in the steppes and 

 it makes the cultivation of mustard nearly impossible in those areas. 

 Aphthona eiipliorhiae, F., is a serious pest of linseed and was found 

 together with Phyllotreta vittula and Psyllodes sp. in one locality. 

 Cabbages were more or less injured by Phyllotreta armoraciae, Koch, 

 P. cruciferae, Gz., P. vittula, Redt., and P. undulata, Kut. Vetches 

 {Vicia sativa) were injured by larvae of Bruchus (Laria) atomarius, L., 

 while B. lentis was reported on lentils. On lucerne, there were found 

 Sitones longulus, Gyll., S. humeralis, St., both in great numbers, and 

 S. hispidulus, F. The following Curculionid pests of fruit trees were 

 reported : — Sciaphobus squalidus, Gyll., Anthonornus pomorum, L., 

 the hibernating adults of which appeared in the first half of April, 

 Rhynchites hetuleti, F., var. violaceiis. Scop., R. auratus. Scop., R. 

 bacchus, L., R. pauxillus. Germ., and R. aeqimius, L. On 18th July a 

 large flight of Amphimallus solstitialis, L., was observed near Stavropol 

 and another of Rhizotrogus aestivalis, Oliv., on 28th April. Adoretus 

 nigrifrons, Stev., is widely distributed over the eastern part of the 

 government. The wheat chafers of the genus Anisoplia have not done 

 much damage during the year under report ; investigations 

 have shown that Anisoplia austriaca, Herbst, var. major, Rttr., is the 

 most common, especially in the east, being replaced to some extent by 

 A. cyathigera, Scop., in the west ; A. zivickii, Fisch., and A. segetum, 

 Herbst, also occur. Maize, watermelons and sunflowers were injured 

 in the south by Pentodon monodon, F. (idiota, Herbst). No great 

 damage was done by Epicometis (Tropinota) hirta, Poda, which did not 

 appear in large numbers ; strawberries were seriously injured in 

 one locality by Oxythyrea stictica, L. 



Dipterous pests included Mayeiiola destructor, Say, which damaged 

 winter-sown crops near Stavropol in September and October. Oscinis 

 Jrit, L., V. pusilla, Meig., appeared on fallen crops and winter-sown 

 ones in September ; the following Chalcid parasites of this pest were 

 reared : Pteromalus {Trichomalus) cristatus, Forst., Rhoptomeris 

 widhalmi, Kurdjumov, and Halticoptera sp. nov. 



Among the Hymenoptera Hylotoma rosarum, Klg., is a common 

 pest of roses, as also are the larvae of H. pagana, Panz., from the 

 cocoons of which Tetrastichus atrocoeruleus, Nees, was reared. Larvae 

 of Cladius albipes, Klug, have injured leaves of cherries ; those of 

 Eriocampa adumbrata, Klug, appeared early in July and those of 

 Uoplocam.pa testudinea, Klug, were occasionally found in apples. 

 Cephus pygmaeus, L., and Trachelus tabidus, F., are very injurious, but 

 it has not yet been ascertained which of the two is the more impor- 

 tant, the differences between the larvae being still unknown. 

 Various species of Isosoma, amongst which Philachrya apterum, 

 Portch., was prevalent, were injurious to grain.
