Replying to J. Pettit, C. W., who sent specimens of chinch 

 bugs, Mr. AValsir states that they "differ remarkably from our 

 specimens by the wings being only half as long as the abdomen." 

 Infers that they ai'e a geographical variety. Species not before 

 known in Canada. Says, "As the insect is more peculiarly a south- 

 ern species, I do not apprehend that it is likely ever to swarm 

 with you, as it often does in the West; and at all events, having 

 such short wings, it will not be able in Canada to fly in swarms 

 from one locality to another as our little pest occasionally does."
