larvae before it penetrates the fruit, and while perfectly suc- 

 cessful in this they found the curculio also had disappeared from 

 their plum trees. "With us," said Mr. Moody, "the insect ques- 

 tion is settled; I care nothing more about insects in our orchard, 

 They can be easily destroyed at slight expense, and at a time too 

 when the poison used does no harm to fruit or trees." 



Prof. C. V. Riley, at the American Pomological meeting, exhib- 

 ited a cyclone nozzle recently invented by him for the benefit of 

 the public, to use in spraying trees. It throws an infintessimally 

 small spray with great force all over and under the leaves and 

 branches at once. He recommends a kerosene emulsion for general 

 use as an insecticide, as it has the additional virtue of killing the 

 scale insects which ordinary insecticides will not destroy. His 

 formula is one quart of milk to two quarts of kerosene, churn seven 

 minutes, dilute the butter with forty parts of water. For tree 

 work he uses a bambo pole with rubber tube inside and the nozzle 

 on the end. Common soft soap mixes well with kerosene, churn 

 the same as with the milk mixture, and dilute the butter with rain 

 water. This kills the red spider. 



Dr. E. L. Sturtevaut's experiment with hens in his plum orchard 

 is described elsewhere. 



Hon. William Saunders, at the U. S. Agricultural Department, 

 explained to me in September last, a successful experiment in 

 tobacco stems in dealing with the grape-leaf hoppers in his green- 

 houses. The stems were strewed upon the ground under the vines — 

 occasionally sprinkled to keep them moist, and the vapor arising 

 from the tobacco kept the insects entirely out of the premises. 

 Prof. Riley says this vapor is less injurious to delicate plants than 

 -either the smoke or the liquid of tobacco. G. 



THE TARNISHED PLANT BUG. 



(Lygus lineolaris, hemiv.) 



By Puof. S. a. Forbes, of Normal, Ills. 



[From the Farmers' Review, Chicae:o, Feb. 28.] 



There are few insects which are capable of greater mischief to 

 the horticulturist than this, and not many whose average injuries 

 reach a larger sum during the season, equally at home, as it is, in
