The Neuroptera of the northern part of Asia, especially the 

 species inhabiting Amurland, have formed the subject of a joint 

 memoir by Messrs. de Selys-Longchamps and M'Lachlan, pub- 

 lished in the fifteenth Tolume of the 'Annales de la Societe 

 Entomologique de Belgique,' 1872. It is a curious fact in the 

 geographical distribution of these insects that of forty-four species 

 of Libellula, L., here described, thirty are met with on the Euro- 

 pean side of the Ural range of mountains, and as many as twenty- 

 five are absolutely natives of Belgium ; and thirty-one species of 

 the other Neuropterous groups found in Britain occur also in 

 Siberia. One new genus (Amphipsyche) among the Phryganeidae 

 is established by Mr. M'Lachlan. 



A memoir on the Neuroptera Planipennia of Scandinavia was 

 published at the close of 1871, by Pastor Wallengren, in the 

 ' Transactions of the Swedish Academy,' in which he describes 

 fifty Swedish species, being the precise number enumerated in 

 the' Catalogue of British Neuroptera,' by Mr. M'Lachlan. 



Several memoirs on Scottish Tenthredinidae, by Mr. P. 

 Cameron, have appeared in the ' Scottish Naturalist.' 



The TenthredinidiB and Siricidae of Scandinavia have been 

 reinvestigated by C. G. Thomson, in a work published in 1871 at 

 Lund (' Hj'menoptera Scandinavise,' 8vo, pp. 1 — 342). It is 

 singular that the larvae of these insects, which Herr Thomson's 

 countr3-man, Prof. Dahlbom, of Lund, had especially investigated 

 and described, should be ignored in this new work. 



Our indefatigable friend, Mr. S. C. Snellen Yan Vollenhoven, 

 the Director of the Entomological portion of the Eoyal Museum 

 at Leyden, has published the third part of his excellent ' Schet- 

 sen ten Gebruike bij de Studie der Hymenoptera,' oblong folio, 

 containing illustrations of ninety-six genera of Chalcididae. The 

 very cheap price at which this work is issued by the Ento- 

 mological Society of the Netherlands ought to ensure a large 

 sale. 



Under the modest title * Ichneumonologische Fragmenle,' Herr 

 Tschek has described a considerable number of new Austrian 

 species of various genera of Ichneumonidae, including eleven 

 Sigaritis and eleven Casinaria (Vienna Zool. Bot. Ver., 1871). 



A memoir b}'^ Professor Achille Costa, on the Aculeated Fos* 

 sorial Hymenoptera of Italy, with figures, appears in the Annuario 

 del Museo Zoologico, anno vi.
