which so strongly marks that sex in Tephritis, is for deposit- 

 ing the eggs between the scales : their horny substance, de- 

 pressed and wedge-shaped form, seem peculiarly adapted to 

 such an operation. As they were very wild, I could never ap- 

 proach near enough to them in fine weather to ascertain the 

 fact; the proof must therefore be left for some more fortunate 

 observer.
