scale-bugs. His experience was that ladybirds suffered little 

 from cyaniding because they were generally shaken to the ground 

 in the course of mounting the tent, and as the gas rose, the lady- 

 birds usually revived, flying away soon after the removal of the 

 tent. In the apple orchards which are infested much by the 

 codlin moth, spraying with lead arsenate is the common practice. 

 Perhaps the most serious pest of the whole country is the com- 

 paratively recently introduced Mediterranean fruit-fly ( Ceratitis 

 capitata) , and the Queensland fruit fly ( Dacus tryo7ii) . It has 

 been recently discovered that kerosene oil is an irresistible attrac- 

 tion to the Mediterranean fly and the hope is now entertained that 

 by trapping the flies with this oil, their ravages will be consider- 

 ably checked. The oil, however, seems to have no attraction for 

 the Queensland fruit-fly (Dacus tryoni) . In the fight against 

 Phylloxera, the use of resistant stocks offers relief. The San Jose 

 scale, at first very numerous and injurious to fruit-trees, is now 

 kept well in check by a number of enemies, the most effective, per- 

 haps, being a lepidopterous larva* described by Mr. Froggatt not 

 long ago . The Chinese wax-scale ( Ceroplastes cerifertis) frequently 

 inhabits fruit-trees in large numbers, but it does not seem to have 

 the poisoning effect upon plant tissues that the San Jose and other 

 scales have. A wash composed of a couple of pounds of washing 

 soda to a bucket of water is the most effective remedy so far 

 used. 



Mr. Froggatt then referred to the Linnean Society of New 

 South "Wales as an old and well established, and one of wealthiest 

 organizations of the kind in the world. Our fellow members. 

 Dr. Perkins and Messrs. Kirkaldy and Terry, are members of the 

 Society. While it is not a strictly entomological society, the 

 volumes published (now amounting to 32) contain a great amount 

 of entomological matter. Though the Field Naturalist's Societies 

 of Australia have a large membership, they are not confined to 

 entomological work, and in entomology they limit themselves 

 practically to life histories. 



Speaking of his own mission around the world, which brought 

 him to the Hawaiian Islands, Mr. Froggatt was proud to have 

 been chosen by both the State Officials and Entomologists of four
