is quite conjectural. Here then is a subject for investigation 

 in a group of insects where one might imagine little was left 

 to be done. 



Flood refuse sometimes yields a rich harvest to the 

 beetle collector. We have a notable instance in a paper 

 just published by Norman H. Joy, 1 in which a list is given 

 of species found in a sack of rubbish sent to the author 

 by a correspondent near Lairg, in Sutherlandshire. The 

 material was carefully sifted in a manner described in the 

 paper, and the spoil was found to consist of no fewer than 

 147 species. In view of the paucity of records from areas 

 so far north, Dr Joy has judged it advisable to publish a 

 complete list of the species. 



Some British species of Hemerobius, a well-known genus 

 of insects allied to the Lacewing Flies, are discussed in a 

 paper by Kenneth J. Morton. 2 The genus has been recently 

 split up by an American author into three, according to 

 differences in the neuration of the wings. These must now 

 be known as Sympherobius, Boriomyia, and Hemerobius (sens, 

 str.). Accordinglto Morton two species of SympJierobius have 

 hitherto been mixed in British collections, viz., striatellus and 

 elegans. A short diagnosis is given, serving to distinguish 

 the two, and of course 5. striatellus must now be added to 

 the British list. 



Students of British Mites will find a paper by the Rev. 

 J. E. Hull, 3 on "British Oribatidae : Notes on New and 

 Critical Species," of much service and indeed indispensable. 

 In this valuable paper, which is illustrated by a plate, twenty- 

 two species are added to the British list, eighteen of which 

 are described as new to science. The article is not yet 

 concluded, but sufficient is already published to indicate its 

 value to workers in this interesting group of Arachnida. 



The list of British Diptera grows ever larger. A paper 

 by A. E. J. Carter 4 records two recent additions, viz., a 

 "Daddy," Amalopis schineri, Kol., taken at Callander in
