288 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.84 



Apparently R. Mayne succeeded Professor Poskin at the station at 

 Gembloux. In the October, 1922, number of the Annales previously 

 referred to he has an article entitled " Organization of International 

 Measures for Entomological Protection." In this article he refers 

 to Monsieur Ghesquiere as Entomologist of the Colony of Belgian 

 Congo. In the Annales for December, 1923, Mayne has an article 

 entitled " Principal Enemies of Coffee in Belgian Congo," and in 

 the number for May, 1924, another one on the Colorado potato beetle, 

 suggested by the appearance of this injurious insect in west France. 

 In the October-November number for 1926 he has an illustrated 

 article on Pissodes in Belgium. 



It is interesting to add that there was published in 1920 a report 

 on the operations of the entomological station from 191 3 to 1919, 

 written by Professor Poskin, The title attracted me because it covers 

 the period of the World War and the period of the occupation of a 

 large part of Belgium by the Germans. In the report there is no men- 

 tion of the war, and the only possible reference to the disturbance 

 occurs in the opening sentence concerning the year 1915, in which the 

 statement is made that the activity of the service, completely ruined 

 beginning with August, 1914, began to show signs of life in 1915. 



Added note. — As this is going through the press, I have received a 

 ten page manuscript from my friend Professor R. Mayne, entitled 

 (translated) " Economic Entomology in Belgium and the Belgian 

 Congo." I am very sorry that I did not receive this manuscript at an 

 earlier date and I earnestly hope that my friend Mayne will publish 

 it in Belgium. 



For the purposes of this book we may add a few statements gained 

 from this article which may supplement what already appears above. 



Mayne attributes the great impulse to applied entomology to 

 Jules Poskin and G. Severin, which eventually resulted in the royal 

 decree attaching the entomological service to the state Agronomical 

 Station at Gembloux in 1909, and the later decree of 191 2 reorgan- 

 izing the central agronomic station. J. Poskin was the first director 

 of the entomological station and was followed in 192 1 by Raymond 

 Mayne who had been his assistant the previous year. 



In 1910 occurred a reorganization by M. Leplae, Director General 

 of Agriculture of the Belgian Congo. The positions of entomologist 

 and mycologist were created and Mr. R. Mayne instituted an ento- 

 mological laboratory in 1911 which in 1913 was transferred to the 

 Botanical Garden of Eala, where a mycological laboratory had already 

 been installed by the late Dr. Camille Vermoesen. Mayne's studies
