are indispensable to the broad taxonomist, but there are no biological 

 data whatever nor is there any indication that any of the species 

 mentioned are of economic importance. 



The publication known as " La Naturaleza " should be mentioned. 

 Doctor Dampf calls it " the valuable Mexican scientific review." It 

 was published from 1869 to 1914. Doctor Dampf also refers to the 

 various agricultural journals (Boletin de la Sociedad Agricola Mexi- 

 cana, from 1879; La Revista Agricola, from 1885, etc.) and to the 

 official i)ublications of the Secretary of Agriculture. In these publi- 

 cations there are many articles on pests, with recommendations for 

 control, but they are mainly taken from foreign publications. 



In 1900 the " Comision de Parasitologia Agricola " was established 

 in Mexico City as a branch of the Mexican Department of Agricul- 

 ture (Secretaria de Fomento) and, under the leadership of Prof. A. 

 L. Herrera, began active work, taking up at once the so-called Morelos 

 fruit-worm {Anastrepha ludens). The inspectors and entomologists 

 of the Commission comprised the following individuals : Amado F. 

 Rangel, L. de la Barreda, Oliverio Tellez, Guillermo Gandara, An- 

 selmo Neraz, Carlos Macias, Gabriel Blanco, Julio Riquelme Inda, 

 Dr. Silvio J. Bonansea. The following were honorary collaborators : 

 Dr. Alfredo Duges, Man. Tellez Pizarro, Dr. Manuel Villada, Dr. 

 Jose Ramirez. 



Between 1900 and 1907 there were published by the Commission 

 four volumes (the last incomplete) of a Boletin de la Comision de 

 Parasitologia Agricola and 75 circulars concerning insect pests and 

 diseases of cultivated plants. 



In 1907 a new service was started and entitled " Direccion General 

 de Agricultura," and all experimental and research work was con- 

 centrated in a Central Agricultural Station in San Jacinto (D. F.) 

 with many substations in various States. The old Parasitological 

 Commission was incorporated in the Central Station under the name 

 (translated) " Division of Parasitology." Professor Herrera re- 

 signed, and Dr. Roman Ramirez, a phytopathologist, was appointed 

 chief. In this Division were J. Riquelme Inda, G. Gandara and 

 Leopold Conradt. In the winter of 1910 Professor Gandara and 

 Senor Riquelme Inda visited Washington, and presumably other parts 

 of the United States. At that time Professor Gandara introduced 

 himself as Professor of Natural History and Plant Pathology, while 

 Riquelme Inda attached to his name the words, " Perito Agricola." 

 Mr. Conradt had been one of the collectors for Godman and Salvin, 

 and was entrusted with the formation of the insect collections.
