Holotype, cf , Nadi, Fiji Is., 7-28, '13. 

 Allotype, 9 , and paratype, 9 , with the type. 



Mongoma, sp. 



A species belonging to the fragillima and australasiae group 

 in the Macleay collection mentioned by Skuse (Dipt. Aust., 

 vol. 4, series second; Proc. Linn. Soc. N. S. W., Sept. 25, 1889; 

 p. 832, 833.) 



Conosia irrorata, Wiedemann. 



Sixteen females taken at a lamp at Nadi, Fiji Islands, Jiily 28, 1913. 

 This series shows a great difference in size in the different individuals. 

 It was prex-iously recorded from these islands by Skuse who noted a 

 specimen in the Macleay collection. (1. c, p. 837, 838). The reason 

 that this entire series consisted of females is undoubtedly due to the 

 nocturnal o\nposition in this species. Series of photophilous craneflies 

 always show a preponderance of the female sex and many of these are 

 gravid specimens ready to deposit their eggs, the others having laid the 

 clutch earUer in the evening. When males occur at lamps or in trap- 

 lanterns it is probable that copulation takes place in the twUight or 

 early evening.
