Allotype, 9, and paratype, 2, 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, 8aa5) 
Conosia irrorata, Wiedemann. 
Sixteen females taken at a lamp at Nadi, Fiji Islands, July 28, 1913. 
This series shows a great difference in size in the different individuals. 
It was previously recorded from these islands by Skuse who noted a 
specimen in the Macleay collection. (l. c., p. 837, 838). The reason 
that this entire series consisted of females is undoubtedly due to the 
nocturnal oviposition 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 earlier in the evening. When males occur at lamps or in trap- 
lanterns it is probable that copulation takes place in the twilight or 
early evening.
