226 CATALOGUE OF THE DESCRIBED HYMENOPTERA OP AUSTRALIA, 



Family EUMENID^. 



The solitary wasps belong to this family, and most of the 

 foreign genera are represented in Australia. Many of them are 

 handsome insects, black and yellow or orange in colour. They are 

 large and aggressive-looking insects, armed with a large sting ; 

 several are commonly known as " mason-wasps," from their 

 building large clay nests in any convenient sheltered place, which 

 they provision with the larvae of moths or spiders. Saussnre, 

 who has made the Vespidce a special study, has described most of 

 our wasps in his " Monograph des Guepes Solitaires," Vol. 1. 1851, 

 and in other papers in the Annales Soc. Ent. France (1857), in 

 the Reise No vara, Hymenoptera (1865), &c. Fabricius described 

 several of our earliest known species in his Syst. Piez. (1804). 

 Gu6rin described some in the "Voyage de la Coquille" (1830), 

 and St. Fargeau dealt with others in his Natural History, 

 Hymenoptera, Vol. IV. (1846). Smith, in his British Museum 

 Catalogue of Hymenoptera, Part y. (1857), gave a list of these, 

 and described several new species.
