 nubilalis, L., [Botys siluceulis, Hb.) did considerable damage to maize, 

 90 per cent, of the stalks being frequently infested ; Phhjdaenodes 

 {Botys) palealis, Schiff. , injm'ed the flowers of carrots in several localities ; 

 the caterpillars entangle the inflorescence in a web and eat the seeds ; 

 GaUeria hieJloneJla, L. ; Pier is brassicae, L., was numerous ; P. rapae, 

 L., greatly damaged cabbage and in some localities took the second 

 place after P. sticiicalis with regard to numbers and the damage done ; 

 a large outbreak of Aporia cralaegi, L., occurred ; the caterpillars 

 of the first generation greatly suffered from various parasites, such as 

 Pimpla instigator (1 per cent.), Tachinids (7 per cent ), and fungus 

 diseases (pebrine) from which 37 per cent, perished ; Malacosoma 

 nenstria, L., Lymantria dispar, L., Stilpnolia {Leucoma) salicis, L., 

 Euproctis {Porthesia) ckrysorrhoea all 'Occurred ; Pliyt-ometra {Plusia) 

 gamma, L., damaged cabbage and beet ; Acronycla tridens, Schiff., was 

 not injurious, the caterpillars being heavily infested with parasites, 

 which was also the case with Acronycta psi, L., A. aceris, L., and A. 

 rumicis, L. ; Trachea {Hadena) basilinea, F., attacked wheat, chiefly 

 the white-eared kind, while " arnautka ^\Triticum durum v. hordeiforme) 

 suffered less ; Oria^ [Tapinostola) musculosa, Hb. was noticed in 

 wheat and on summer-sown crops generally ; Chloridea {Heliothis)

 Agrotis c-nigrum, L. ; A. ravida, Schiff. {obscura, Brahm) ; A.

 together with Polia {M.) persicariae, L., P. pisi, L., P. oleracea, L., 

 and Scotogramma {M.) trifolii, Rott., and others ; they damaged beet 

 as well as cabbage ; Ejnsetna {Diloba) coeruleocephalu, L. ; Hylophila 

 {Halias) prasinana, L., on oaks ; Arctia caja, L., a large outbi'eak of 

 which occurred in one pine forest of the Zmievsk district without doing 

 very serious damage ; a great number of the caterpillars were infested 

 with the muscardine fungus ; Diacrisia {Spilosoma) lubricipeda, L., 

 was frequently found on cabbage in late summer.

 sticiicalis , L., in the Bogoduchovsk district of the govt, of 

 Charkov], pp. 66-78, tables VII-X. 



This is an accomit of investigations in the Bogoduchovsk district, 

 where a large outbreak of Phlyctaenodes sticticalis occurred in the year 

 imder report. Out of a total of 7,720 acres of beet plajitations in the 

 district only 32 per cent, were untouched by the caterpillars, while 

 8"3 per cent, were destroyed, 21*7 per cent, were seriously and 38 

 per cent, were more or less damaged. The large numbers of the first 

 generation came to an end in the second half of May and the first 

 caterpillars were noticed on 3rd June and by the 9th July tliey had all 

 pupated. Heavy rains do not wash the caterpillars oft", but contiiuial 

 rain, followed by a drop in the temperature to 18° F., delays their 

 gro\\'th and many of them pupate without reaching their normal size. 

 A few instances of observed migrations of the caterpillars are given, 

 evidently occasioned by scarcity of food. Trenches round the plant- 

 ations were nearly ever\^vhere used as a preventive measure and spraying
