flies are occasionally toiiiid on foliage, but more often on the sunny side of tree- 

 tranks, upon which they run about actively whilst displaying their wings in 

 constantly changing positions. None of the introduced or indigenous fruits 

 are known to be attacked by this species. 



The imago has been fuUy described by Professor M. Bezzi (1919), to 

 whom specimens were forwarded through the courtesy of Dr. G. A. K. Marshall. 

 The larva and puparium may be briefly described as follows : — 



Larva (Figs. 1—3). 



Length, 11.0 mm.; width, 2.0 nun.; creamy white, with eleven visible seg- 

 ments; anterior end pointed, posterior end truncate, widest at 5th and 6th seg- 

 ments; anterior spiracles with from 12 to 14 processes. 



Puparium (Fig. 4). 



Length, 6.5 mm.; width, 2.70 mm.; short, broad; burnt sienna coloured; 

 with 10 visilde segments.

I ha\e noticed this species at only one tree, where the females were observed 

 hovering near matter exuding from a termite-infested trunk or, in one case, 

 ovipositing in a crevice from which the fluid was issuing. Larval development, 

 and sometimes pupation, takes place in the galleries made by the termites; 

 generally, Iiowever, the mature larvae leave the shelter of the galleries and
