shows that this is a most fruitful method of collecting, and 

 also suggests the large amount of systematic work that remains 

 to be done in the Australian Hymenoptera. 



A great preponderance of females is to be expected in insects, 

 especially bees, visiting flowers for honey ; but there are some 

 interesting exceptions. Thus thirty-two males of Paracolletes 

 nr. vigilans were taken, together with six females, probably 

 belonging to the same species. The Thijniiidae, on the other 

 hand, were chiefly males — again in accordance with the habits 

 of the group ; for the males of these Fossores visit flowers, often 

 carrying the wingless female in coitu. Some of the species 

 of Diptera {Lonchaeidae, Sepsidae and Sapromyzidae) were 

 probably visiting the tree for egg-laying.
