(Gr., ";) The characters of this genus are sufficiently set forth above. Two of the five known North American species occur in Indiana. 1353 (4093). Linn., Svst. Nat., II, 1706, 651. Elongate, subconvex. Black, shining; marked with small, irregularly disposed blotches of pale silvery scales; each side of thorax with a large roimded black eye-like spot surrounded by a ring of jiale scales. Ely- tra distinctly striate; intervals convex, finely and sparsely punctulate. Length 28^5 mm. (Fig. 277.) Throughout the State; frequent in the south- ern portion; less so in the northern counties, ilarch 16-October 21. This is the best known member of the family in the State.
