distortion of the leaf sheath and the adjacent stem. This insect is 

 much less important in New York State than the wheat joint worm. 

 A survey of wheat insects would be incomplete without taking 

 into account the joint worms. Data in relation to these two insects 

 were collected by Prof. C. R. Crosby of Cornell University in 

 cooperation with the late W. R. McConnell of the Bureau of Ento- 

 mology. The latter has been succeeded in this work by P. R. 

 Meyers of the federal Hessian fly laboratory at Carlisle, Pa. The 

 data have been kindly placed at our disposal by Professor Crosby 

 and is summarized below, since it may be utilized in determining 

 the probabilities of injury by these insects in subsequent years.
