Metcalf's work is drawn largely from entomological sources 

 (18). Lampa's Report on the Work of the Entomological Divi- 

 sion of the Swedish Agricultural Station for 1905 contains brief 

 notes on a number of more or less noxious Swedish insects, most 

 of which are also British (15). 



Tullgren publishes his impressions of the economic work 

 done at Copenhagen, Hamburg, Wageningen, Geissenheim, 

 Vienna, Budapest, Halle, and Berlin (28). 



Silvestri continues his researches on Machilidse, and promises 

 a monograph. Incidentally he gives a synoptic table of the 

 palsearctic species of Machilis (25). Wahlgren (29) synopsizes 

 the Thysanura and Collembola of Sweden in a paper which will 

 be useful to British workers, while Lie-Pettersen (13) contributes 

 to our knowledge of these forms in Northern Norway. 



Berlese describes and discusses the morphology and anatomy 

 of a Locustid with two ovipositors (3). 



Horvath has monographed the palsearctic Tingidae, with 

 tables of genera and species, and references to food-plants. The 

 coloured plate is one of Fieber's, unpublished for about forty
