32 ANNALS OF SCOTTISH NATURAL HISTORY 



of these were Walkerian species of Sceliomd&, etc., the list, 

 so far as these are concerned, cannot be regarded as a critical 

 one. The following illustration will show how largely M. 

 Kieffer has increased our knowledge of these minute insects. 

 In Marshall's catalogue are recorded 1 5 British species of 

 Anteon, mostly described by Walker ; in the present list 47 

 species of that genus are recorded from Scotland. 



Not much is known about the natural history of the 

 BetJiylida and the Dryinincs. Species of the former group 

 have been reared from Lepidopterous, Coleopterous, and 

 Dipterous larvae, and some species have been taken in ants' 

 nests. The Dryinin(z, so far as we know, are parasites on 

 Honwptera ( TypJilocyba, etc.). Aplielopns melaleucus has been 

 reared by Giard in France from TypJilocyba kippocastani and 

 T. Douglasi. The species in Scotland appear chiefly in June. 

 Many species of Oxyura may, however, be found in the 

 autumn in fungi. 



In the following lists the species recorded in Marshall's 

 catalogue are marked thus *.

By recent authors, following the example of Haliday, this group 

 is referred to the Aculeate division of the Hymenoptera.
