167. Byrrhus Cyclophorus Kirby.–Length of body 3¼ lines.One specimen only taken.

Body underneath and limbs dull feriuginous, above black with some cinerous hairs intermixed. Antennae piceous: elytra with two deep black subinterrupted stripes, and inscribed in the middle with traces of a circle formed of pale, or cinercous hairs, common to both.
