The extensive collections of Australian erane-fiies contained in the South 

 Australian Museum have been kindly sent to me for determination by the Board 

 of Governors. A considerable number of new species, distributed in many 

 .genera, were found to be included ; of these genera, Orimargula, Elephantomyia, 

 Ceratocheilus, Epiphragma, Stibadocerella, and Phacelodocera had never been 

 recorded from the Australasian region. Most of the novelties were from localities 

 in which little or no work had been done on the Tipulidae, such being Tasmania, 

 the Dorrigo Tableland in New South Wales, Lord Howe and Norfolk Islands, 

 and Bathurst and Melville Islands in North Australia. The writer's thanks are 

 due to tlie various collectors of this unusually valuable series of Australian 

 Tipuloidea, especially to the Museum Entomologist, Mr. Arthur M. Lea, who 

 personally collected most of the material. The types of all the new species have 

 been returned to tlie South Australian Museum, paratypes of some species 

 represented I)y more than two iiulividuals being preserved in the writer's 

 collection. 



Venation. The wing-venation of the species of crane-flies considered in the 

 present report is interpreted in accordance with the principles of the Comstock- 

 Needham system (fig. 335). The fundamentals of this system are briefly 

 outlined here, the students being referred to more detailed accounts (^) for 

 additional particulars. 



The wing of an insect is composed of membranes traversed by a series of 

 longitudinal veins extending from the base to the outer margin, and bound 

 together at various points by cross-veins and deflections of the longitudinal veins, 

 which form strong fusions at these places. There are six or seven longitudinal
