;il)out three months before the flies began to emerge about the 

 end of September. 



Fly varying from ih to 3 Unes in length, all black except the 

 white tarsi; head broad, rugose between the eyes; antennae 

 spindle-shaped, pointed towards the tips, standing straight out, 

 without any terminal bristle; thorax rounded in front, broadest 

 about the middle, finely granulated on the dorsal surface; scutel- 

 lum almost square, the apical edge having a short spine on either 

 side; legs stout; wings dusky, nervures black, the wings creased 

 in the centre and folded down over the tip of the abdomen; the 

 latter constricted at the base, large and round, finely granulated, 

 with the apical segments turning downwards, and the extreme 

 tip truncate. 



This is a typical form of the family Strati omyiicke, and is, I 

 believe, identical with Bigot's C. alhitarsis, one of the few described 

 Australian species. 



Another very pretty little fly also lives in the rotten caudex, the 

 larvfe of which I have never observed, but have bred several from 

 the pupaj, which are oval brown cases covered with particles of 

 earth, the front broadest, with a cylindrical short truncate spine 

 on either side, standing out like a little horn, the apical tip rather 

 pointed. 



The fly, which belongs to the family Trypetince, is often found 

 upon the leaves, moving its wings up and down (as many members 

 of this family do when resting), but is very hard to catch ; 

 common in November. 



Fly 3 lines in length; head black, narrow; last joint of the 

 antennae large and circular, terminated with a stout bristle; head 

 and thorax hairy, the latter steely blue; scutellum large, yellow, 

 with black markings on the apical edge which is truncate and 

 fi'inged with hairs; legs long, pale yellow; wings hyaline, thickly 

 mottled with irregular black blotches over the apical half; abdo- 

 men broad, heart-shaped, pale ochreous yellow, rounded on dorsal 

 surface, with a curious imprinted brown mark in centre; thin 

 and flat on the underside, tinged with black towards the tip, and 

 tufted with silvery white hairs on the sides.
