Carynota Fitch. 



The genus is distinguished by the lovi^, smooth, rounded prono- 

 tum which is virithout crest or horns and is produced downward at 

 the sides to cover at least two-thirds of the tegmina, the sessile 

 terminal cells of the hind wings, and the hairy and robust appear- 

 ance. The species of this genus are fine large insects and show 

 distinctive markings. Three species are represented.

Very common throughout eastern United States on hickory and 

 butternut in the North and on white oak and pecan in the South. 



The insects are large (females lomm. ; males 8.5 mm.); 

 ground color gray, with a rich brown or chestnut band across the 

 pronotum behind the middle, and the apex of the posterior process 

 brown; pronotum convex and elevated; tegmina fuscous-hyaline 

 tipped with dark brown. 



The eggs are laid on hickory or butternut in late Summer, hatch 

 about the middle of the following June, and the insects reach 

 maturity about the middle of July. The entire life is spent on 

 one host. 



Hosts : Hickory, butternut, white oak, pecan, red oak, basswood.

Not common. A smaller species than the preceding (females 

 not over 8 mm., and males slightly smaller) and distinguished by 

 the markings. The ground color is brown, irregularly dotted 

 with yellow, with a broad transverse yellow band at the base of 

 the posterior process ; the dorsum is higher and more arched than
