to save the crop ; Pericallia ricini, which also attacks beans ; 

 Eublemma olivacea, which can best be controlled in the pupal stage, 

 as the cocoons are fairly easily seen ; Prodenia litura, which appears 

 to be omnivorous, and two other species of Lepidoptera. 



Cucurbitaceous plants are infested by the larva of Phytometra 

 peponis {Plusia agramma) and Glyphodes indica, both of which 

 specially attack snake gourd. 



Malvaceous plants are attacked by Sylepta derogata and Anomis 

 {Cosmophih) erosa ; leaves infested by the former should be destroyed, 

 and to control the latter hand-picking must be resorted to. 



Kohl-rabi, turnips and cabbages are all liable to infestation by 

 Hellula undalis and Plutella maculipennis, both of which can only 

 be controlled by spraying ; Idaea fibulata ; Phytometra (Plusia) 

 orichalcea and Croctdolomia binotalis, which can only be controlled 

 by hand-picking.

III. — Entomologist, London, 1, no. 647, April 1917, pp. 76-82. 



The Aphids dealt with in this paper include Pemphigus borealis, 

 Tullgr., on lettuce roots, which probably migrates from poplars to 

 lettuce ; Brachycolus stellariae, Hardy, on galled leaves of Stellaria 

 sp. ; Macrosiphum loti, Theo., on Lotus corniadatus from various 

 localities and also recorded by Mordwilko from Russia, being placed 

 by him in the genus Acyrthosiphon ; M. rubifolium, sp. n., described 

 from specimens taken on blackberries {Ruhis fruticosus) and 

 raspberries {R. idaeus) in company with Amphorophora rubi, Kalt. ; 

 M. euphorbiellum, sp. n., described from specimens on spurge 

 {Euphorbia esula) ; Acyrthosiphon genistae, Mordw., taken on various 

 species of Genista; Myzus festucae, sp. n., described from specimens 

 taken on Festina oviim var. rubra, the grass being killed owing to 

 the number present ; Rhopalosiphum aconiti, Van der Goot, from 

 Yorkshire, the only other record of this species known to the author 

 being from Holland. A colony of Prociphilus crataegi, Tullgr., was 

 placed in breeding jars with rooted grasses and other plants ; though 

 the winged forms did not appear to show any inclination to migrate 

 and young were produced by them, no trace of their descendants 

 could be found on the roots of some fifteen species of plants.

 (Eneyrtidae : Chalcidoidea) from Italy. — Entomologists' Mthly. 

 Mag., London, 3rd Ser. no. 28, April 1917, p. 80. 



The author now describes as a new species imder the name 

 Eusemion italicum an insect previously described and figured by him 

 as Cerapterocerus corniger. Walk. This Chalcid has been bred from 

 the Coccid, Ceroplastes rusci, in Italy.
