such as soap or glue is necessary and tliat nicotine gave better results 

 than arsenicals. As the over-wintering eggs and hatching larvae 

 occur exclusively on the lower side of the leaves within a few inches 

 of the ground, the best results were obtained with a horizontal spray. 



A weevil, Gcodcrces incomptus, proved locally destructive. Crambits 

 hortuellus (cranberry girdler) was widespread, but caused compara- 

 tively little damage. 



For the control of San Jose scale [Aspidiotus ferniciosus] lime- 

 sulphur, 3° Be., is usually efficient ; scales that are resistant to this 

 strength will be equally resistant to a greater concentration and 

 should therefore be treated with a good grade heavy oil spray.

Ann. Rept. 1918-19, Washin<^ton State Coll. Agric. Expt. Sta., 



Pullman, Bull. 155, March 1920, pp. 23-25. [Received 31st

The various investigations carried out in previous years have been 



continued, and the work planned for the future is briefly discussed. 



Olsen (C. E.). Another European Leafhopper in North America.— 



Bull. Brooklyn Ent. Soc, xvi, no. 2, April 1921, pp. 33-37, 1 plate. 

 Some specimens of a leafhopper, believed to be Euteitix osljomi, 

 which has only been recorded from Texas and California, have been 

 found on tamarisk {Tamarix gallica). Comparison with European 

 exam pies, however, shows that Eutettix oshorni. Ball, is in fact a synonym 

 of Euscelis ( Athysanus) stactogalus, Fieb. The leafhoppers in question 

 had probably been introduced from Europe with their food-plant.

with Description of a Parasite of Trachelus tahidus Fabricius 



(Hymenoptera : Chalcidoidea). —Proc. Ent. Soc, Washington, 



D.C., xxiii, no. 5, May 1921, pp. 113-120, 2 figs. 



Pleurotropis henefica, sp. n., here described, was reared from the 



sawfly, Trachelus tabidus, F. [cf. R. A.E., A, viii, 348]. The characters, 



especially those of the antennae of the genus Pleurotropis, are discussed. 



Cbiatti (V.). I Nemici della Vite. [Insect Enemies of the Vine.] — 

 Riv. Agric., Parma, xxvi, no. 21, 27th May 1921. pp. 300-301. 

 This popular article deals with various insect pests of the vine, 

 including mole-crickets [Gryllotalpa gryllotalpd], various Coccids, 

 beetles such as Otiorrhynchus, Rhynchites and Haltica ampelophaga, 

 and mites. The remedies advised are those commonly employed.

 [Received 1st June 1921.] 

 The caprification of figs, and the role played by Blastophaga grossorum 

 during the process, are discussed [cf. R. A.E., A, viii, 534 ; ix, ILS].

 Univ. Agric. Expt. Sta., Berkeley, Circ. 226, December 1920, 4 pp. 

 [Received 1st June 1921.] 

 The protection of vineyards from Phylloxera by means of quarantine 

 regulations and the use of resistant stock are discussed.
