were confined to the rodent, Citellus {Spermojjhilus) guttatus, T., and 

 to the methods of controUing it. While in Astrachan various fungus 

 and insect pests were investigated. The author mentions especially 

 Locusla (Pachytylus) 7nigratoria, L., Calliptamus (Caloptenus) italicus, 

 L., and Phlyctaenodes (Eurycreon) sticticalis, against the last of which 

 he urgently advises reploughing the fields in early spring. Further 

 trials of Coccobacillus acridiorum against the locusts arc also recom- 

 mended.

The only remedy applied in the Crimea against Rhynchites paiixillus. 

 Germ., consists in shaking them from the trees ; Anthonomus pomorum 

 has destroyed the harvest of apples in many orchards and has done 

 considerable damage also to pears ; removal of the damaged blossoms 

 is practised against it ; outbreaks of Rhynchites bacchus, L., occurred 

 in the steppe orchards in the district of Mehtopol ; the sawfly, Hoplo- 

 campa brevis, Klug, has caused great damage round Alushta and along 

 the River Katcha ; remedies against it consist of shaking the insects 

 from the trees and spraying the young buds with milk of Hme ; 

 HoplocamjM fulvicomis, Klug, did serious damage to plum trees near 

 Simferopol and in some other locaUties ; Aphididae were numerous, 

 especially on standard trees ; Hyponomeuta malinellm, ZelL, although 

 still numerous, loses its importance as a pest, being successfully 

 combated. Great damage was caused by various species of Coccidae, 

 to* which serious attention will have to be paid. 



The following pests of field crops are also reported : Bmchycolus 

 noxius, Mordw., did less damage than was expected in spring, owing 

 to the vigorous state of the crop ; experience has shown that late 

 sowings suffer less from this aphis, and reploughing the barley stubbles 

 and the plants growing from fallen grain is recommended. The seed- 

 hngs of infested winter-sown crops should be destroyed and sheep 

 grazed on them in spring, as rolling has proved ineffective. Pentaphis 

 trivialis appeared on small areas, but disappeared in the middle of the 

 summer. Oria {Tapinostola) muscidosa did great damage in the 

 neighbouring government of Ekaterinoslav, but appeared only in the 

 district of Berdiansk in Taurida. Lema melanopa has increased 

 during the last two or three years ; powdering the affected plants 

 with ashes and spraying with Paris green have been successful, while 

 reploughing tends to destroy the larvae pupating in the soil.

 The larvae of Chlorops taeniopus, Meig., appear in May and beginning 

 of June and injure the growing point of the stems of barley, thus 

 preventing further growth and development. According to the
