neighbouring government of Astrachan, as the latter species is replaced 

 to the east of the river Don by C. hoefti. Melasoma {Lino) populi, L., 

 occurred on poplars, and Otiorrhynchus aurosparsus, Germ., was found 

 in great numbers in orchards. The nature of the injury done by this 

 weevil is similar to that caused by Sciaphobus squalidus. No males 

 have been found, and this species is beheved to multiply by partheno- 

 genesis. Other weevils include : — Otiorrhynchus ligustici, L., doing 

 considerable damage to lucerne ; Phyllobius oblongus, L., in great 

 numbers in orchards, especiaUy on plum trees ; Phyllobius pyri, L., 

 and Eudipnus micans, F., on elm-trees ; Sciaphobus squalidus, Gyll., 

 present in large numbers and doing considerable damage, particularly 

 to pear-trees ; Psalidium maxillosum, F., on mustard ; Bothynoderes 

 punctiventris, Germ,, and Conorrhynchus nigrivittis, PaU., var. kinder- 

 manni, Fst. Some observations by A. D. Shamrai on Lixus ascanii 

 on mustard are at variance with some statements of N. Sacharov [see 

 this Review, Ser. A, i, p. 536, and ii, p. 355] with regard to the number of 

 generations and the mode in which the stems are hollowed by the 

 larvae of this species. According to Shamrai, there are two generations, 

 or at least the hatching of the second generation takes place before 

 the winter, these weevils hibernating as adults and not as larvae. 

 Ceuthorrhynchus macula-alba, Hbst., did considerable damage to 

 poppies in some localities, and Baris scolopacea, Germ., was present in 

 large numbers on fodder beet. An enormous outbreak of Anthonomus 

 pomorum, L., occurred in the year under report, great damage being 

 done to apple trees, while pear trees suffered less. Byctiscus betulae, L. 

 {Rhynchites betuleti, F.) on vines ; R. auratus, Scop., on cherries ; 

 R. bacchus, L., on stone-fruits ; R. giganteus, Kryn., R. pauxillus, Germ., 

 R. aequatus, L., Anisoplia austriaca, Hbst, var. major, Rttr,, A. zwickii, 

 Fisch., A. cyathigera, Scop., and A. segetimi, Hbst., Epicomstis 

 (Tropinota) hirta, Poda, and Oxythyrea funesta (stictica) on raspberries ; 

 Blitopertha lineata, on haricot beans and wheat ; and Pentodon idiota, 

 Hbst,, were also present. 



Dipterous pests included : — Oscinella frit, L,, var, pusilla, Meig., on 

 oats, and Contarinia tritici, Kirby. 



Hymenoptera : Xylocopa violacea, ¥., was reported from one locahty 

 to be damaging beams in houses. Adults of Eurytoma amygdali. End., 

 were reared from plum stones. Eriocampoides limacimi, L. {Eriocampa 

 adumbrata, Klug) was found in the larval stage on cherries, Hoplo- 

 campafidvicm'nis, Kl., on plums, and Athalia colibri, Christ {spinarum, 

 F,), on cabbages and mustard, A large outbreak of Cephus pygmaeus, 

 L,, and Trachelus tabidus, L., occurred in the year under report. As 

 this was accompanied by similarly large numbers of the parasite, 

 Collyria calcitrator, Grav,, it was not probable that they would reappear 

 again in such numbers in 1915.
