MIGRATION OF WATER-BEETLES AT BROKEN HILL, 
bei NEW SOUTH WAI.ES. 
The following little history of the migratory powers of tlie 
water beetle Eretrs australis (Erichs), forwarded by Mr. Fred. 
i|. \\. Shepherd of Broken Hill, may be of some interest: —

On Thursday, 30th. of April, 1925, about 9 o’clock in the 
evening, a friend of mine was attracted by a noise as if heavy 
lam or hail were falling on tlie roof of his house; it being a bright 
moonlight night, he went outside to investigate and found, as he 
said, countless thousands of the above beetles swarmine on his 
roof and filling up the water spouting all round the house. He 
became alainied and called on me to see if the posts were harm- 
ful; of course T allayed his fears on that score and told him how 
these insects flew out of the water at night time and went looking 
lor fresh watery homes, and that evdclently the\' had mistaken 
his roof for a pool of clear water. The reason 1 came to that 
conclusion was that the gentleman had just had a new iron roof 
placed on his house, and it shone in the moonlight like a lake 
of water.
