XIV.— Diptera Nematocera from the Moun- 

 tains of Borneo. By F. W. Edwards.

This report is based on two collections made in Sarawak by 

 Dr. E. Mjoberg and sent by him to the British Museum for 

 determination. The first was made on Mts. Murud and Dulit 

 in the latter part of 1922, and received in London in the sum- 

 mer of 1923 ; the second, from Mts. Pol and Penrissen, was 

 received in April 1924. It appeared desirable to combine the 

 reports on the two collections, in order to give us as good an 

 idea as possible in one paper of the Nematocerous fauna of the 

 island. Thanks to the generosity of the Sarawak Museum 

 the types of all the new species have been retained, as well as 

 examples of some other species which were not previously re- 

 presented in the British Museum collections. Duplicates, 

 when available, have been returned to the Sarawak Museum. 



The collection consisted mainly of Tipulidae, of which there 

 were no less tlian 89 species represented among just under 200 

 specimens ; of these it has been found necessary to describe 

 51 as new. Some of the supposed new species may periiaps 

 be found later on to be identical with forms described recently 

 by Alexander from Japan or Formosa, but in the great majority 

 of cases this is unlikely. The result is indeed hardly surpris- 

 ing, considering the little that was previously known about 

 the Cranefly fauna of Borneo, and the strong tendency of mem- 

 bers of this family to develop local and endemic species, 

 especially in mountainous regions. 



So far as I have been able to discover, the following list 

 includes all the Craneflies hitherto recorded from Borneo, as 

 well as a few unrecorded species which are represented in the 

 British Museum.
