WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 257 



of nearly 600 pages entitled (translated) "Agricultural Entomology 

 According to the Lessons of Prof. F. Silvestri." These lessons, or 

 lectures, were recorded and inilolished under the name of Dr. Guido 

 Grandi, Assistant in the Laboratory of Entomology at Portici. The 

 lessons were originally published in leaflets (dispense), and the work 

 as a whole is one of the very best of its kind that has ever been 

 published. 



Professor Silvestri has been a great traveler. He has gone on 

 expeditions to Italian Africa for the Italian Government; has visited 

 many jiarts of the world for the Hawaiian people, principally in order 

 to secure the natural enemies of the Mediterranean and Oriental 

 fruit-flies ; for the State of California, to secure parasites of injurious 

 scale insects. He has visited most parts of the world, and has been 

 in the United States on three occasions. He attended the Fourth 

 International Congress of Entomology at Ithaca in August, 1928, and 

 has delivered a course of lectures at the University of Minnesota. 

 He is a man of great force and of much personal charm, and now 

 speaks English fluently. He is one of the foremost of the men who 

 have distinguished themselves as international entomologists. 



A number of publications dealing with entomological problems 

 from the economic point of view were published in Italy from time to 

 time during the period preceding the World War.^ 



In 1912, L. Vivarelli published two volumes of an Agricultural 

 Entomology, the one on insects injurious to the vine and the other 

 on insects injurious to fruit. In 1924 a revised edition of Volume I, 

 very much enlarged, was published. 



This second edition contains nearly a hundred additional pages, 

 reaching the size of xv + 350 pages, and carries 93 figures. The 



*I have just learned some rather definite facts about Professor Silvestri. He 

 was born June 22, 1873, and is therefore at this writing approaching his 57th 

 birthday. He has crowded into his comparatively short life more important 

 work and more travel than any other entomologist whose records are known 

 to me. He has published 113 papers, and he has traveled practically everywhere. 

 He was in the Argentine doing important work as early as 1898. He became 

 Chief of the Department of General and Agricultural Zoology at Portici in 1904, 

 and Director of the Royal Agricultural School at Portici in 1920. He early 

 traveled for the Argentine Government, visiting Formosa as early as 1900. 

 He made wide-spread explorations for the Hawaiian Government in 1912 and 

 1913. He traveled again widely in the Orient for the State of California in 

 1924 and 1925. His list of scientific voyages, including parts of South, Central, 

 and North America, Africa, China, and Japan, have numbered 21. He is an 

 honorary or corresponding member of 23 learned societies, and has been the 

 recipient of four great prizes. The last one was the Grand St. Hilaire Medal 

 of the National Acclimatization Society of France.
