which their lines run. He considered this an important point for the student of ento- 

 mology to bear in mind. Of course such a man must go out and study conditions over a 

 vast area. He must also know what our worthy chairman is doing in Colorado ; what 

 Mr. Weed is doing in New Hampshire ; what Mr. Lounsbury is doing in South Africa ; 

 what Dr. Fletcher is doing in Canada — in short he must keep posted on the entomology 

 of the whole world and be ready to meet any emergency. 



Prof. Hopkins said that he found in the spruce forests of Maine that a large timber 

 concern controlling some 300,000 acres employed a practical forester and scientific man, 

 and paid him about $1,500 a year, to give advice on practical methods of cutting timber 

 and making surveys. The ooncern mentioned sent this man with the speaker through 

 the spruce forests of Maine to learn all he could about forest insects. This was another 

 evidence of the fact that the practical men are beginning to realize that they can very 

 profitably make use of the results of scientific research, 



A vote of thanks to the chairman for his interesting and suggestive address was un- 

 animously adopted. 



Dr. L. 0. Howard, in the first paper, detailed the operations performed in the intro- 

 duction and establishment of the Blastophaga in the fig plantations of California, which 

 had been carried on since the last meeting. The paper will be published in full in the 

 Year-book of the U.S. Department of Agriculture for 1900. 



Establishment of a New Beneficial Insect in California.. 



A second note presented by Dr. Howard also related to the introduction of a bene- 

 ficial insect. He stated that it would perhaps be remembered that at the tenth annual 

 meeting of this Association he had referred to his eSorts to introduce and establish in 

 this country, with the assistance of Prof. Antonio Berlese, of Italy, the interesting 

 Oriental parasite know^n as Scutellista cyanea. In Italy this curious parasite occurs 

 commonly in the wax scale (Ceroplastes rusci), and it was introduced into Italy in all 

 probability from the Orient about forty years ago, although originally described by 

 Motschulsky in 1859 from specimens reared by Nietner in Ceylon from Lecanium coffeos. 

 The living specimens were sent by Dr. Berlese and his colleague, Dr. Leonardi, and were 

 colonized at Baton Rouge, La. ; also in Washington D.O., in the insectary of the Division 

 of Entomology upon Ceroplastes cirrij)ediformis. The Washington specimens did ^ not 

 suf.ceed in perpetuating the species and nothing has been found since of the Louisiana 

 material. A year later Mr. C. P. Lounsbury, government entomologist of Cape Colony, 

 found this species parasitic upon Lecanium olece, the common black scale, in Cape Colony, 

 and sent specimens to the writer for identification. The past spring, Mr. Lounsbury, at 

 the writers request, made formally through the United States Secretary of Agriculture 

 to the Secretary of Agriculture of Cape Colony, brought with him from Cape Town to 

 New York two boxes of twigs covered with the black scale affected with this parasite, 

 and expressed them to Washington, whence they were immediately forwarded to Mr. E. 

 M. Ehrhorn, the horticultural inspector of Santa Clara County, Cal. On June 19 the 

 writer received a letter from Mr. Ehrhorn announcing the arrival in living and 

 healthy condition of the parasites in question. The twigs in one box were somewhat 

 mouldy but quite a number of parasites were crawling about in the box and were found 

 in the pupal condition in some of the scales. Mr. Ehrhorn had been warned by telegraph 

 and had prepared twenty-five infested oleander plants by potting them and had covered 

 each with a tight bag of the finest Swiss muslin. In these most of the parasites were 

 liberated and a few were allowed to fly in the orchard. Specimens of a hyperparasite 

 (Tetrasiichus sp.) also survived the journey, but Mr. Ehrhorn was on the lookout for this 

 parasite and isolated them as they appeared, pending instructions from Washington a.i to 

 their destruction. The writer had strong hope of the successful establishment of this 

 species at San Jose, the climate being appropriate and the supply of food unlimited, and 

 stated further that this was another instance of international entomological work which 

 emphasized the fact that this Association through this class of work binds together its 

 members all over the world more than any other association. 



At the opening of the discussion on the paper, Dr. Howard said that he would be 

 glad to hear from Mr. Lounsbury on the subject of this parasite of the black scale. He
