Mr. Webster, referring to the subject of the setting of clover seed, 

 said that in his experience a good crop of seed always followed an 

 attack of the clover leaf- weevil, and, therefore, the latter insect is often 

 actually a means of putting money into the pockets of the farmers. 



Mr. Howard read a paper entitled "Remarks on steam spraying 

 machines,' 1 which will appear in full in the Yearbook of the Depart- 

 ment of Agriculture for 1896. 



Some discussion followed on the subject of nozzles, the experience of 

 different members with various nozzles being given. The " cyclone" 

 nozzle was objected to by some on the ground of its lack of sufficient 

 carrying power. The McGowan nozzle had not always given good sat- 

 isfaction. The Xixon nozzle was also mentioned. The general opinion 

 seemed to be that the "cyclone" nozzle was the best for all ordinary 

 purposes, supplemented with the Xixon and McGowan for spraying 

 larger trees. 



Mr. Webster stated that inquiries were beginning to come in from 

 farmers and orchardists for a steam-spraying apparatus and that he 

 was convinced that as soon as a practical machine was put on the market 

 it would be in great demand. 



Mr. Fernald said that the botanist of the Massachusetts Station, at 

 Amherst, had been using some sort of steam-spraying apparatus and 

 regarded it as a success. 



Mr. Howard stated that a very satisfactory apparatus could now be 

 bad for about $300, which was considerably less than first estimates. 



All of the papers the authors of which were present having been 

 read, and the hour being late, on motion of Mr. Howard, it was ordered 

 that the balance of the papers in the hands of the secretary be read by 

 title and left to the executive committee to determine whether or not they 

 should be included in the published report of the proceedings. The 

 committee deemed all the papers in question worthy of publication, and 

 thev are here included. 



NOTES ON NEW AND OLD SCALE INSECTS. 



By W. G. Johnson, College Pari; Md. 



In December, 1894, I discovered a scale insect on cherry trees at 

 Champaign, 111., which, on account of the nature of its attack, I con- 

 sider a very important economic species. After a careful study of a 

 large amount of material and much correspondence with Dr. L. O. 

 Howard and Prof. T. D. A. Cockerell, I believe the species is new to 

 science and have described it as Aspidiotus forbesi and have given it 

 the popular name of the cherry scale. The description of this species, 

 together with four others mentioned below, will appear in an illus- 

 trated article soon to be published in the Bulletin of the Illinois State 

 Laboratory of Natural History, Vol. IV, Art. XIII.
