A Myriopod Stated to Injure Vegetation. — Writing October 2, 1903, Mr. J. F. 

 Schermerhorn, Alton, 111., sent a specimen of the larger and common myriopod, 

 Spirobolus marginatus Say, with statement that it had been found on a leaf of egg- 

 plant and that when disturbed it emitted a fluid that destroyed vegetation within 

 ten minutes. It is well known that myriopods contain a small amount of hydro- 

 cyanic acid, but we have no records of injury to vegetation at the present time by 

 any of these insects in the manner described.
