WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 457 



The personnel of this service has of course undergone many 

 changes since it was created. Mr. R. Hart and Mr. C. H. Ballou 

 served at one time as inspectors, the latter also as " Entomologist." 

 Dr. M. Sanchez Roig (D. en C. and D. en M.) succeeded Mr. John- 

 ston as Chief of the service, and served until early in 1926. Mr. S. C. 

 Bruner acted as Chief ad interim a short time during the fall of 1926, 

 until Dr. Ruiz Mesa (D. en M.) the present Chief was appointed. 

 Mr. E. Sanchez Estrada is now the Acting Chief of the Service, and 

 Major Jesus L. Vega (D. en M. V.) is the " Military Supervisor." 



In 1924 the Tropical Plant Research Foundation of the United 

 States National Research Council established an experiment station 

 at Central Baragua, at the request of an association of Cuban cane 

 planters known as the Cuba Sugar Club. The station is known as 

 " Estacion Experimental del Qub Azucarero de Cuba." Mr. D. L. 

 Van Dine, long-time member of the staff of the United States 

 Bureau of Entomology and at one time engaged in entomological 

 work in Hawaii and later in Porto Rico, went to Cuba in November, 

 1924, with C. E. Stahl, also an old employee of the United States 

 Bureau, as his assistant. Later Mr. Van Dine became local director 

 of all the work, including pathology, agriculture, and chemistry, and 

 the organization was changed from a project basis to the standard 

 experiment station plan. Mr. Stahl became chief entomologist, and 

 Mr. H. K. Plank, also formerly of the Bureau, was engaged later. 

 Mr. Stahl resigned in 1929, and his place was taken by U. C. Loftin, 

 also formerly of the United States Bureau. Mr. L. C. Scaramuzza 

 has been an entomological assistant and has been working on the 

 biology of moth-borer parasites. These men have done excellent work 

 and have published seven Bulletins and eight Scientific Contributions. 

 An especially good article by Mr. Plank entitled " Natural Enemies of 

 the Sugar Cane Moth-Borer in Cuba " was published in the Annals of 

 the Entomological Society of America, Vol. 22, No. 4, December, 

 1929, pp. 621-640. 



PORTO RICO' 



The insect fauna of Porto Rico and other islands of the West 

 Indies has attracted the attention of naturalists since the early days 



'The major part of this section on Porto Rico has been prepared at my 

 request by Dr. R. T. Cotton, who tells me that the statements regarding the 

 early entomological history of Porto Rico have been gathered from an account 

 prepared by Augustin Navarrete, a former secretary of the Sugar Producers 

 Association of Porto Rico and from Doctor Wolcott's " Insectae Portoricensis," 

 Journ. Dept. Agr. P. R., Vol. 7, No. i, 1923.
