This is by far the oldest genuine Scarabaeid known, but it seems clearly to belong to the Rutelini in the vicinity of Pelidnota and Cotalpa. The reference is strongly supported by the abdomen and prothorax, which show the presence of such a type in the deposit, or at least indicate a veritable Scarabseid. As it is impossible to definitely refer the insect to a living genus, I propose the name Pelidnotites for it. EXPLANATION OF PLATE XVL Fig. 1. Elaterites palceophilus, Ckll., X 3. P. 458, Fig. 2.
