This species appears to be widely dispersed, but it is still a 

 local insect ; it is not uncommon about Battersea and Hammer- 

 smith during June and July. Mr. Wollaston brought examples 

 from Cornwall. It makes its burrows in decaying wood. Stelis 

 phceoptera has been observed entering its nests. 



As there is a doubt whether Fourcroy's Apis hirta is really 

 synonymous, Latreille's name has been adopted for the species.
