 the interrupted band, of yellow hairs : scutellum dark brown. Elytra marked with 

 yellow upon their margins ; the basal third is marked with an oblique line, succeeded

Clytus campestris ( Oliv.). 



This is a small species, from four- to six-tenths of an inch long. Its color is brown, 

 marked with two waved bands across the elytra and tips. The pronotum has four yellow

 between the bark and wood, and also penetrate into the wood. The perfect insect appears 

 in May and June. It inhabits the Northern States, New- York and New-England, and ex- 

 tends as far south as Carolina (Haldemak, Am. Phil. Transactions, x, 40).
