 lotreta. [The Larvae of Flea-beetles of the genus Phyllotreta.] — 

 Illustrierte landtv. Ztg., no. 75-76, 1919, pp. 382-383. (Abstract 

 in Zeilschr. landw. Versuchsivesen in Deutschdsterreich, Vienna, 

 xxii, no. 11-12, November-December 1919, p. 294.) 



The larvae of the following species of Phyllotreta and their life- 

 history are described : Phyllotreta vittula, Redt., P. nemorum, L., 

 P. armoraeiae,' Koch, P. ochripes, Curt., P. tetrastigma. Com., P. 

 undulata, Kutsch., P. nigripes, F., P. atra, F., and P. nodicornis, 

 Marsh. The authors consider P. atra, ¥., and P. crvciferae, Goeze, to 

 be varieties of the same species, the former name having priority. 

 Destruction of the beetles in mid-summer, autumn and early spring is 

 the remedial measure advised.

 xxii, no. 11-12, November-December 1919, pp. 294-295.) 



The larvae of Phytomyza jlavicornis. Fall., feed on the stalks of 

 cauhflowers, and those of Phorbia {Chortophila) trichodactyla on the 

 cotyledons of young bean plants ; beans sown early near Berlin are 

 severely affected, whereas late-sown plants remain quite uninfested, 

 contrary to what is reported to have occurred in Holland. Some species 

 of Lygus perforate the leaves of sunflowers ; these bugs may be captured 

 on boards smeared with an adhesive, or spraying with Dufour's 

 solution may be resorted to.
