The antenna) are inserted under the sides of the front; the anterior are transverse, subconical, and somewhat prominent; the hind coxie are transverse; the hind troclianters are at the inner margin of the tliighs; the tarsi are 5-jointcd. The species live in fungi fud under bark. Our v,\vo genera without frontal ocellus arc distinguished by the form of the antcnnuj. Antennas with the joints 9—11 larger. Pbotkim-s.

The latter genus is further remarkable for having the sides of the thorax frequently with an angle behind the middle; the thorax is also always chauuellcd. Tribe IX.—PHLffiOCHARIlVI. This tribe consists also of a very small number of species, of slender, depressed form, and is represented in our fauna only l)y the genus Olisthajrus, found in the northern regions, from Canada to Russian America, under bark. The prothoracic spiracles are covered; the thorax behind the anterior coxa; is membranous; the latter are conical and prtjmi- nent, and the hind coxa; are transverse; the hind troclianters are on the Internal margin of the thighs; the tarsi are 5-jointed. The antenna; are inserted under the sides of the front, straight, 11-jointed, scarcely thickened externally. The second ventral segment is longitudinally elevated at the middle. It will thus be seen that this tribe differs from Oraalini by the absenc
