SOME NOTES ON THE LIFE HISTORY 



The smallest perfect specimen measured 9'5 mm. by 8'5 

 mm. breadth of abdomen being 4 mm. This was a male. 



The largest males are however larger than the smallest 

 females. 



The antennae, length from 3 to 3 '5 mm. consist of eleven 

 segments. The first segment, fitting into the head between 

 the eyes with a ball and socket joint, is a long and thick one, 

 the second small, almost spherical; the next four are short 

 and thick, the remaining five rather thicker and covered with 

 fine hairs, the last being long and pointed. 



The last four segments of the flagellum are coloured black, 

 all the other segments being transparent. 



(b) 



The wings of the insect have two main folds when lying 

 shut against the slightly convex dorsal surface of the abdomen, 

 one fold running from the apex to nearly the centre of the 

 posterior margin, the other fold across from about a third of 

 the anterior margin from the apex almost parallel to the 

 posterior fold. Each main foLl has a fan-like fold in it, before 

 turning under the other portion of the wing. 



The veins of the wing are strongly marked, all lying 

 within that portion of the wing which lies flat on the abdomen. 



The diagrams above (not to scale) show (a) the positions 

 of the wings lying flat on the abdomen, and (b) one wing 

 extended, with its venation. 



Larva. 



The eggs from which the larvae hatch out, are laid in 

 bunches. The size of each egg is about 2 mm. long, and '6 mm. 

 in greatest diameter.
