of the specimens. The ice was entirely melted on arrival at Mar- 

 seilles, and the cocoons had become moist. 



The experiment has never been repeated, but it seems quite 

 possible that it might be successfully carried out at any time. 



ANTIGUA 



A paper by A. Gallwey reported in 1929 that attempts had been 

 made to control the moth borer of sugar cane in Antigua by Braco- 

 nids, Ipobracon and Microdus, introduced from British Guiana, and 

 begun in 1927. This material was probably originally found in Brit- 

 ish Guiana by Harold E. Box. The results are reported to have been 

 inconclusive. 



ARGENTINA 



Aside from the successful introduction and acclimatization of 

 Aphelinus mali, the only other experiment of record was the introduc- 

 tion from Italy of Prospaltella herlcsei How. in 191 3. It was reported 

 in 1916 that 4,650 fruit-growers had applied for twigs carrying para- 

 sitized scales and had received in all 530,000 twigs, making a total of 

 3,000,000 twigs distributed during three years. At the time of writ- 

 ing it was considered that the parasite was sufficiently well es- 

 tablished, and the distribution of parasitized twigs was about to be 

 discontinued. 



AUSTRALIA 



Largely through Mr. George Compere while acting as Entomolo- 

 gist for Western Australia, many parasites were introduced from 

 California and from Hawaii, most of them parasites of scale insects ; 

 and Doctor Tillyard sent to Australia colonies of Aphelinus mali, 

 descendants of those he had secured for New Zealand from the 

 United States. Several other importations have been urged, ajid at 

 least one of them was tried without success. The sheep blow-fly, a 

 great pest in Australia, was studied carefully by several writers in 

 Australia, and seven of its native parasites were also carefully studied. 

 These parasites, however, did not control the pest, and during April 

 of 1925, according to W. B. Gurney and A. R. Woodhull (Bulletin 

 2y, Department of Agriculture, New South Wales, May, 1926), a 

 few parasites of the Euroi>ean blow-fly were reared from pupae sent 

 from England. These parasites were Alysiu manducator, and they did 

 not attack the Australian maggots although they were tried with 

 several species. I understand that later experiments have been made 

 to introduce European enemies of blow-flies, and I remember with
