Lake and Kosciusko counties, Ind., June 15 — July 12. The 

 known range extends from Ontario and New England west to 

 Illinois and south to Maryland. Distinguished principally by 

 the long beak. Knight's specimens were taken on young hickory 

 trees in July. He states (1921, 128) that Uhler: "In describ- 

 ing grandis had under observation at least four different species 

 and made allowance to cover all the forms which he took to be 

 merely variations. Nearly every species collected from the 

 United States that is larger than nebulosus has at one time or 

 another stood under the name grandis."
