South, and that many were asking if the Texas crude oil could be used 

 in place of the Pennsylvania crude oil. He had used the Texas crude 

 oil last summer as a summer treatment, with no injurious effect. 



Mr. Caudell remarked that he had used the Texas crude oil while in 

 Texas to keep ants from his insect collection. He understood that 

 one defect was that it was of a very sticky nature, and if used on 

 plants was likely to fill up the pores, thus suffocating them. 



Mr. Marlatt stated in connection with the lime, sulphur, and salt 

 wash that in his opinion a considerable part of the lime commonly 

 used might just as well be left out. He thought that the use of 

 kerosene emulsion would become more general from the fact that it 

 was possible to secure a definite strength, no matter how the pump 

 might work. He stated that there was some difficulty in preparing it, 

 but if made as in California the work was greatly simplified. It is 

 made up and put on the market, so that anyone desiring it in small 

 quantities can secure it at no great advance in price. 



Mr. Harris stated that he had used "Corsicana" oil in certain 

 experiments against the cotton-boll weevil in Texas, and it was his 

 experience that it had killed the plants. 



The next paper was presented by Mr. Felt, and was on the following- 

 subject: 



NOTES ON INJURIOUS INSECTS. 



By E. P. Felt, Albany, X. Y.

The discussion of this paper was deferred until several of a similar 

 character had been presented. 



Mr. Osborn then presented the following paper: 



INSECTS OF THE SEASON IN OHIO. 

 By Herbert Osborn, Columbus, Ohio. 



In a previous paper 1 have noted some of the insect occurrences of 

 the early part of the season; and as there has been no very excessive 

 abundance of any pest during the Latter part of the year, a rather brief 

 review will suffice to put on record such as have attracted attention. 



Grapevines have 4 suffered quite severely from attacks of the leaf- 

 hoppers (Typhlocyha spp.), in some cases the vines showing a decided 

 wilting and the crop being evidently materially checked in growth. 

 Leaf-hoppers, too, have been quite troublesome on roses and noted on 

 many other plants. They are possibly only in about the average 

 abundance.
