 covering pp. 193 to 256, completes the Rhynchota and begins to deal 

 with the Coleopterous pests.

Many scale-insects hve on the vine, either normally or through 

 some accidental cause. In his work on the Coccidae of Europe and 

 North Africa, Lindinger lecoids — Lepidosaphes ulmi, L., Aulacaspis 

 (Diaspis) pentagona, Targ., Parlatoria oleae, Colv., Aspidiotus rapax, 

 Comst., A. Jabiatarum, March., Chrysomphalus aurantii, Mask.,

 Bouche, E. {L.) persicae, F., PhysoJcermes coryli, L., Pulvinaria 

 betnlae, L., Pseudococcus {Dactylopius) vitis, Nied., and Pulvinaria 

 vitis, L. In France the vine is chiefly infested by four species viz : — 

 Pulvinaria vitis, Eulecanium persicae, Targionia viiis and Pseudo- 

 coccus vitis. The enemies of these Coccids include birds and insects. 

 Earwigs destroy the eggs and larvae of E. persicae and probably also 

 those of Pulvinaria vitis, Coccinella septempunctata, L., Chilocoi'Us 

 renipustulatus, Scr., C. bipustulatus, L., and Exochointis quadripustulatus, 

 L., are the Coccinellids of most interest to French growers. The 

 Noctuid, Eublemma (Coccidiphaga) scitula, Ramb., does good work 

 against Ceroplastes rusci and S. oleae. The larvae of Chrysopa vulgaris, 

 Wesm., feed on young individuals of E. persicae in summer and 

 autumn. The Crabronid, Spilomena troglodytes, Lind., is an important 

 enemy of Pulvinaria vitis, L., the larvae of which are stored in its nest. 



Chalcidoid enemies include : — Encyrtids — Ericydnus ventralis, 

 Dalm., Blastothrix schoenherri, Dalm., B. sericea, Dalm., Aphycus 

 punctipes, Dalm., Encyrtus duplicatus, Nees, Eucotnys swederi, Dalm., 

 Chiloneurus elegans, Dalm., Cerapterocerus mirabilis, Westw., and 

 Scutellista cyanea, Motsh. ; Pteromahds — Eunotus cretaceus. Walk., 

 and Pachyneuron coccorum, L. ; Eulophids — Eulophus scutellaris, 

 Nees, and Aphelinus scutellaris, Dalm. The larvae of Leucopis an- 

 nulipes, Zett., feed on the eggs of Pulvinaria vitis. A bibliography 

 of 27 works completes this useful compilation.
