During the past ten years the writer has been engaged in a study of the 

 crane-flies of the Australasian Region, with the ultimate view of monographing 

 the group from this Region. During the progress of this study, very large and 

 interesting collections of Australian Tipulidae have been received for study from 

 the authorities in charge of the collections of the South Australian Museum, the 

 Queensland Museum, the British Museum of Natural History, the Paris Museum, 

 the Natural History Museum in Vienna, the Berniee P. Bishop Museum in Hono- 

 lulu, and other notable collections. Very valuable notes on the present condition 

 of the Skuse Collection in the Macleay Museum were sent me by the Acting 

 Curator, Mr. John Shewan, through the ceurtesy of the Senate of the University 

 of Sydney. In addition, many individual collectors have generously submitted 

 material, among these men being Messrs. Alan P. Dodd, Hardy, Heron, Hill, 

 IllingTvorth, Searle and Tillyard. The writer's sincere thanks and appreciation 

 are extended to these collectors and custodians of the collections above listed for 

 their kind co-operation in this matter. In the present paper, a few undescribed 

 species are discussed and some records of distribution for other species given. 

 Unless stated to the contrary, the types of the new species described herein are 

 preserved in the collection of the writer.
