82 THE EEPOET OF THE No. 36 



perfectly quiet until about 7.30 p.m., when they began their endeavours to attract 

 the males. The fore-wings were moved very rapidly, the vibrations producing a 

 slight hammering sound ; the hind-wings are held close to the body, and motionless. 

 Many others noticed drumming behaved in exactly the same manner. Six males 

 were taken at the cage; others were seen, but escaped. 



Aug. 20. — Trapped one male, which was admitted to the cage, and soon mated, 

 and eggs were dropped during the night. Several other males were attracted. 



Aug. 21. — Two or three males were attracted, but I was unable to trap one ; the 

 night was windy. 



Aug. 22. — None attracted, one seen on the wing; night cold. 



Aug. 23. — Another fresh female was secured and put in the same cage and the 

 door opened at 7.30. A male was attracted and mated; the other did not attract. 



Aug. 24:.- — A fresh male was netted, and on being put in the cage soon mated 

 with the old but hitherto unpaired female, and eggs were dropped the same night. 



Aug. 25. — A few more eggs dropped. 



Aug. 26. — The female died this morning. 



A good way to take the species is to watch for the flight about 7 p.m., and 

 as soon as dark enough take a lantern and search for them. They are then found 

 in pairs, clinging to grass and other low plants usualjy some six or eight inches from 

 the ground, or clinging to the side of the house. The time of flight varies, probably 

 being a little earlier on a clear than a cloudy evening, but they are seldom on the 

 wing before seven o'clock, and almost never after eight o'clock.
