sides. Elytra marked as in figure, and the posterior femora extending to 

 tip of elytra.

Black or brown with white markings, very constant in arrangement. 

 This species varies somewhat in the form of the thorax which is usually 

 nearly quadrate, a little wider than long, but sometimes very much wider. 



N. longipes Kirby. Fn. Bor. Am., IV, 1837, p. 176. 



Length 9 — n mm. = .36 — .44 ins. Hab. Texas, Va., Can. 

 Black with white markings as in our figure, but sometimes parti) 

 obliterated. This species runs very close to the preceding, is however 

 more slender, especially in the form of the thorax, the legs are longer, 

 and the tip of the elytra tends more to the acuminate form. The base 

 of the elytra bears very much more white hair. 



N. torquatus Lee. S. M. C, No. 264, 1873, p. 200. 



Length 7.1 — 12 mm. = .3c — .48 ins. Hab. Texas. 



Black with yellow bands. Might be confused with erylhrocephalus, 

 but is easily known by the transverse yellow band at middle ofprothorax. 

 The anterior femora are finely dentate beneath, not very obviously in 

 small specimens. 



EURYSCELIS, Chev. 



This genus was erected by Chevrolat for a few species with twelve 

 jointed antennae, one of which has occured in the United States. 



E. suturalis < >liv. Ent., IV. 1705. 70, p. 62, t. 7, f. 91; Lap & (lory, Mon., 

 p. 15, t. 4, f. 16; Chev., Mon., 1862, p. 530; longipes Dej. Cat., 3d ed., p. 357. 

 Length (■>), — 11 mm. = .26— .44 ins. Hah. St. Domingo., N. V., Tex. 

 I have two specimens before me, one from New York and one from 

 Texas. Light brown with white pubescence. The thorax is carinate. 

 like Neoclyhis and the femora spinose. 



CLYTANTHUS, Thorn. 



This genus, which has neither the frontal carina nor thoracic ridges 

 is separated from Clytus by the narrow episterna of the metathorax. 

 The two species differ greatly in the elytra! marking which are described 

 below.

Length 7— 12 mm. = .28 — .48 ins. Hab. Canada to Virginia, Maine to Illinois.
