Between the 28th and 30bh May a great flight of Ldbellula i-maculata 

 was observed throughout the government, passing from south-west 

 to north-east. There was also a great outbreak of Bihio marci, L., 

 which, although recorded by some authorities as a pest, has not been 

 observed to do damage. The Chrysomelid beetle, Gastroidea viridula, 

 Deg., has greatly injured leaves of sorrel near Zmijev. Roses have 

 suffered from many pests, their leaves being attacked by larvae of 

 Emphytus rufocinctus (?), their buds by larvae of Aradis plana (?) and 

 their stems and shoots by Aulacaspis {Diaspis) rosae. Several in- 

 stances of caterpillars of Gastropacha quercifolia on plums and cherries 

 were reported. Chermes strobilobins (?) was found on larches in Charkov, 

 where spraying with quassia and green soap was very effective against it. 

 The larvae of Lithocolletis populifoliella, Fr., a large outbreak of which 

 had occurred on poplar trees the previous year, were again observed 

 in Charkov, but in smaller numbers. Larvae of Rhynchaenus (Orchestes) 

 quercus, L. injured the leaves of oaks in one locality and by the middle 

 of June many trees had quite an autumn appearance.

Phlyctaenodes (Eurycreon) sticticalis, L., was at its maximum on 28th 

 May, but the numbers of this species were, however, negligible in 

 comparison with the previous year. In some localities of the district 

 of Voltchansk, the caterpillars have injured beet. Aporia crataegi 

 appeared in small numbers owing to the activity in the previous 

 year of parasites and fungus diseases which destroyed some 45 per cent. 

 of the caterpillars and pupae. This year the percentage of infestation 

 with parasites is even greater, the most numerous being Pimpla 

 instigator and some Tachinids. Against Hyponomeuta malinellus, 

 Zell., good results were obtained by spraying with 1| per cent, of 

 barium chloride, which, when applied at the proper time, gave a death- 

 rate of 100 per cent. Polydrosus sericeus injured leaves of young 

 seedlings in one orchard ; handpicking and shaking down from the 

 trees was the remedy used. In two districts of the government 

 apple trees have suffered greatly from Rhynchites pauxillus, which 

 in conjunction with a fungus, Polysticta briardi{1), was responsible for 

 the dropping of the leaves ; the different yarieties were not equally 

 affected, that known as " Borovinka " suf^ring most. Anthonomus 

 pomorum has damaged some orchards in the district of Vn1|inVi .^^"IJCil
