738 CATALOGUE OF THE DESCRIBED HYMENOPTERA OF AUSTRALIA, 



the Hymenoptera they are closely allied, and coming between 

 FormicidcB and Scolididce seem to form a connecting link between 

 the ants and the latter group of fossorial wasps. Little or 

 nothing has been observed about the habits of our Australian 

 species, but it is most likely that both MtUilla and Thyiuius store 

 their nests with other insects for the larvje to feed upon like the 

 winged females of the Sphegidce, ifec, as European species have 

 been dug out of the sand in chambers containing the remains of 

 other insects. The first species recorded from Australia were 

 described from the Banksian Museum by Fabricius (Ent. Syst. 

 1775). In Westwood's "Arcana Entomologica " (1842) the 

 preAaously described ones were i-edescribed, figured, and a number 

 of new species added. In the British Museum Catalogue of 

 Hymenoptera (1855), Smith gave a list of all the described species, 

 and supplemented it with twenty-four new species ; since his 

 Catalogue he has added a number of new species chiefly from 

 Western Australia in his " Descriptions of New Species of 

 Hymenoptera in the British Museum" (1879). In 1883 Kohl 

 described two more in the Verb. Gesell. z.-b. Wien, XXXII.
