UvAROV (B. p.) & Glazunov (V. A.). OSsopii BpeAMTeneii. [A review 

 of pests.]— OTHeTii AtflTenbHOCTM CTaepono/ibCKaro 3htomo- 

 JiorMHecKaro Eiopo sa 1914 roflli. [Report on the work of the 

 Entomological Bureau of Stavropol for 1914], published by the 

 Department of Agriculture of the Ministry of Agriculture, Petro- 

 grad, 1916, pp. 13-54, 7 figs. 



This is a list of pests in the Government of Stavropol during the 

 year under report, omitting many of those in previous reports [see this 

 Review, Ser. A, i, p. 459, and iii, p. 44], but containing some additional 

 ones. Owing to the absence of N. V. Kurdjumov at the front, a great 

 number of Hymenopterous parasites of pests could not be identified, 

 while Dipterous parasites could not be sent to France to Dr. Villeneuve. 



The pests recorded include : — Thrips linarius, Uzel, which was 

 observed on flax, both in its larval and adult stages, its attacks 

 delaying and distorting the growth of the plant. 



Rhynchota : Aelia acuminata, L., A. sibirica, Reut., and .4. rostrata, 

 Boh.,were present in large numbers on wheat and wild grasses; Palom&tia 

 prasina, L., occurred occasionally on gooseberries, and Carpocoris 

 lumtlatKS, Goeze, on flax, Eurydema ornatum, L., in the eastern part 

 of the government, was present in some number on cabbages and 

 radishes in market-gardens, and on rape and mustard in the fields ; 

 only two generations occur during the summer, the first one becoming 

 mature in June and the second reaching the imago stage prior to 

 hibernation. The chief injury to cabbage is done by the hibernating 

 adult and by the larva of the first generation ; the second generation 

 of the larvae feeds mainly on the outer leaves without doing appreciable 

 damage ; the eggs of the second generation were infested by a parasite, 

 probably Trissolcus siinoni, Mayr. E. festivum, L., is occasionally 

 found together with the foregoing species, and in one locality a number 

 of E. festivum var. chloroticum, Horv., were caught on winter crops. 

 The following occurred on gooseberries : — Syromastis margimttus, L., 

 Rhyparochromus chiragra, F., Calyptonotus rolandri, L., Drymus 

 sylvaticus, F., Piesma maculata, L., and Monanthia echii, Schrk. 

 Montandoniella, dacica. Put., was found singly on fruit trees, but as, 

 according to A. N. Kiritchenko, this is a predaceous species, it must be 

 excluded from the list of pests for 1913 [see this Review, Ser. A, iii, p. 44]. 

 AdelpJiocoris seticornis, L., was found amongst great numbers of 

 A. lineolatus, together with A. vandalicus, Rossi, and A. ticinensis, 

 Mey. Bracliycolus scriptus, F., also occurred in company with these. 

 Lygus pratensis, L., and single examples of L. halmi, L., were found on 

 gooseberries, L. rubricatus, Fall., {rubicundus, Mey.) on fruit trees 

 under trap-belts, and Poeciloscytuscognatus, Fieb., in great numbers on 

 a great variety of plants, including mustard, rape, lucerne and sun- 

 flower. Typhlocyba rosae, F., was present from the end of March to the 

 end of August, doing considerable injury to roses, apples, plums and 

 gooseberries. 



Aphids included : — • Eriosoma (Schizoneura) laMgerum, Haus. ; 

 CJiaitophorus populi, L., on Populus alba ; Macrosiphum granarium, 

 Kirby, {cereale, Kalt.) on barley and wheat ; Acyrthosiphon pisi, Kalt., 

 on lucerne; Hyalopterus arundinis, F., on apricots and plums; 

 Rhopalosiphim ribis, Buckt., both stem-mothers and young individuals 

 of the second generation, on gooseberries ; Toxoptera graminum, Rond., 

 on the leaves of oats, where colonies of M. granarium occurred on the
