Family APID^. 



This very interesting family is well represented in Australia, 

 although there have been few workers at our Australian bees. 

 Smith has described the majority of our known species in the 

 British Museum Catalogue of Hymenoptera (1853), where he also 

 catalogues those previously described by Fabricius, St. Fargeau, 

 and others. Since then he has contributed further papers in the 

 Transactions of the Entomological Society of London (1862-64, 

 1864-66, and 1868), in the Zoologist for 1859, and in "New 

 Species of Hymenoptera in the British Museum " (1879). 



In the genus Megachile we have a great number of handsome 

 bees that form nests in trees and walls, the cells of which they 

 line with leaves ; while several species of the genus Xylocopa 

 (the carpenter bees) are numerous in Australia, and one species 

 forms its nest in blie flower-stem of the grass-tree (Xanthorrhcea). 



Only one species of native bee (Trigonla carbonaria) has been 

 described, though there are certainly two, if not three sjjecies in
