with the Austrahan Diptera. Although I shall always regret 

 not being able to obtain more works of reference, the papers 

 that Mr. Skuse has written contain so much reliable informa- 

 tion on the classification and arrangement of the genera that 

 I feel I shall avoid most of the errors that would have been 

 unavoidable without some firm basis and summary of other 

 methods of classification. 



The following table will show the classification adopted by 

 Mr. Skuse, which is the one that I shall adhere to in my 

 papers on the New Zealand Diptera : —
