great distinctness encountering a vile odor in the garden of the Para- 

 site Laboratory at Farnham Royal in 1927 and upon inquiry being 

 told that it came from the dead body of a cat on which were feeding 

 maggots from which it was expected to rear parasites for shipment 

 to Australia. 



BRAZIL 



Novius cardiiialis was imported into Sao Paulo, Brazil, from South 

 Africa and later from Italy and Uruguay. According to Dr. C. H. T. 

 Townsend, in 1921 it was firmly established and the Icerya was in 

 the way of being exterminated. 



When Prospaltella herlesci was introduced into Uruguay in 1920, 

 it was sent to Argentina the following year, and arrangements were 

 also made to introduce it into Brazil; and in 1921 notice was given 

 in Sao Paulo to the effect that the parasite was now obtainable by 

 orchard growers suffering from Diaspis pcntagona on their trees 

 and that supplies could be obtained from the phytopathological ser- 

 vice of the State. 



CANADA 



In 1913 J. D. Tothill, having been sent by the Canadian Government 

 to study the parasites of the brown-tail moth being reared for the 

 United States in Massachusetts, took puparia of Compsilura concin- 

 nata from Massachusetts to two localities in New Brunswick, and also 

 other parasites and the predacious beetle, Calosoma sycopJianta. 



Not long after the United States Bureau of Entomology began to 

 import parasites of the European corn borer, a parasite laboratory 

 was established in lower Ontario ; material was sent on from the 

 United States parasite laboratories, and large numbers of several 

 species of Ichneumonids and Tachinids of European origin were lib- 

 erated in Ontario fields. 



As a rule Canada has been content to share with the United States 

 parasites imported by the latter that afifect introduced pests common 

 to both countries. The United States, with more means, with more 

 trained assistants, has been heretofore in better position to charge 

 itself with the somewhat dangerous work. Of late, however, Canada 

 has been training very good men, has more means than formerly and 

 has become comj^etent to do work of this kind, although a beautiful 

 spirit of cooperation still exists in such work between the two 

 countries. 



There was, however, one very interesting importation made by 

 Canadian experts as early as 191 1. Dr. C. Gordon Hewitt had found 

 in England (in 1908) an important parasite {Mesolaiiis tenthrcdi-
