SOME BEES COLLECTED IN QUEENSLAND. 



By T. D. a. Cockerell. 



The present paper is a report on a collection of bees recently sent from the 

 Queensland Museum. All were collected by JVIr. H. Hacker in Queensland, with the 

 exception of a single Halictus from New South Wales. Mr. Hacker's industry is 

 revealing a remarkable bee-faima in the region about Brisbane. A rather surprising 

 number of the Mackay species, knowii from the collections of Rowland and Gilbert 

 Turner, go south to Brisbane ; while several of the New South Wales s|3ecies also 

 occur, no doubt near the northern limit of this range. There are, in addition, many 

 species discovered by ]Mr. Hacker, and not at present known from other parts of the 

 country. The numbers cited in the list are those of the Queensland Museum.
