244 DIPTERA NE]\rATOCERA. 



Only 7 of these 18 species are represented in the present col- 

 lections so that the total number of Craneflies now known from 

 Borneo is 100. This of course can only be a small fraction of 

 the number which occurs. 



The four Mycetophilidae described here are, I believe, the 

 first members of this family to be recorded from the island. 



In regard to the Culicidae, Mr. J. C. Moulton has published 

 (in 13th Report Sarawak Museum, 1925, pp. 46-48) a list 

 of the 92 species known from Borneo. The present collection 

 contained only three species, but it was a surprise to discover 

 that all of these were additions to the Bornean list, two being 

 apparently undescribed.
