 siderable damage to the important timothy crop. 



A late letter i'rom Prof. P. E. Uhler informs me that the species was 

 first brought to his notice about twenty years ago, from Canada. Since 

 then, he states, it has spread to Baltimore, where it is occasionally very 

 numerous, locally, along the edges of fields of wheat, oats and timothy, 

 in June. 



Mr. Smith stated that he had found the species in New Jersey, at an 

 elevation of only 15 to 20 feet above tide water. 



Mr. Osborn said the species occurred in Iowa, but had not been ob- 

 served ou Timothy. 



Mr. Webster said that Leptopterna dolohrata Linn, had developed in 

 the grass and clover fields, in Ohio, iu immense numbers the present 

 year. While many farmers were, for a time, considerably worried over 

 their appearance, no damage had been reported. 



The next paper was read by the Secretary.
