Mexico, the A. articulatus on Citrus trees and many other plants in the 

 AVest Indies, the A. personatus on numerous plants in the West Indies, 

 •etc. 



(3) That past experience shows that these Mexican and West Indian 

 species are likely to be introduced in the United States, if no precau- 

 tionary measures are taken; and that some of them, at least, may be 

 found to flourish over a considerable portion of N. A. Witness, for ex- 

 ample, the West Indian Diaspis amygda/i now injuring peach trees as far 

 north as the city of Washington. 



(4) That the results obtained by the horticultural quarantine officer of 

 California show that it is possible to prevent by due vigilance, the intro- 

 duction of numerous insect pests. Thus Mr. Craw has quite lately found 

 on plants which were about to be landed at San Francisco a number of 

 species of scale insects foreign to this country, several of them undoubt- 

 edly quite pernicious. 



(5) That when the immense interests at stake are considered, the sum 

 of money required to support a system of inspection and quarantine along 

 the southern border of the United States appears quite insignificant. If 

 but one serious pest were kept out of the country in a year, the saving 

 would more than equal the cost. 



(6) That there should accordingly be appointed horticultural quarantine 

 officers at Nogales, El Paso, Eagle Pass, Laredo, Galveston, New Orleans, 

 Mobile and Key West. 



(7) That these officers should be empowered by the laws of their re- 

 spective States and Territories to examine all plants introduced through 

 their several localities, and destroy all found to be infested by insects. 



(8) That when the quarantine officers have examined and passed a 

 plant or collection of plants, they should issue a certificate to that effect 

 to the importers, and that it should be made illegal to possess imported 

 plants without such certificate. 



(9) That the quarantine officers should be appointed by the Agricul- 

 tural Experiment Stations of their several States and Territories and paid 

 out of the funds of said States and Territories the necessary amount 

 being appropriated to the Agric. Experiment Station for that purpose. 



(10) That while much good could be accomplished as above, it is also 

 very necessary to learn what injurious insects exist in all the regions to 

 the south of us, so as to be warned of their probable advent in this 

 •country; and also to ascertain their natural distribution and life-histories, 

 parasites, etc., so as to be prepared to meet them intelligently. 



(ir) That while observing with much satisfaction the recent temporary 

 appointment of an agent by the Department of Agriculture to travel in 

 Mexico and determine such points as the above, and freely acknowledging 

 the importance of the results thus obtained, we cannot regard this as 

 more than a beginning of an investigation which should at least occupy 

 many years. Thus for example, we are still ignorant of the injurious 

 insects inhabiting the whole west coast of Mexico south of Guavmas, of
