middle of the eyes, two small rrnde fovea9, mutually scarcely as distant as 

 either from the eye, connected by a feebly impressed anterior groove; an- 

 tennal tuberculations small, ratber prominent; antenna? three -fourths as 

 long as the head and prothorax together, moderately robust, club moderate, 

 the joints nine to eleven gradually and uniformly wider, the latter oval, as 

 long as the three preceding together; under surface deeply and densely 

 punctate, with an impressed fovea in the middle at the base, without long 

 erect setae. Prothorax slightly shorter and narrower than the head, widest 

 at one-third the length from the apex, very slightly wider than long; sides 

 strongly rounded anteriorly, rather strongly convergent and nearly straight 

 to the base; the latter broadly arcuate, two-thirds as wide as the disk, very 

 slightly wider than the apex; the latter transversely truncate; dislc feebly 

 convex, with a slightly elongate foveas near the center, a broad impression at 

 one-fourth the length from the base, and, on each side, a large rounded 

 deeply-impressed foveae, at two-fifths the length from the base, not connected 

 with the median impression; surface very feebly and not densely punctate. 

 Elytra at the humeri slightly wider than the prothorax; sides nearly parallel, 

 distinctly arcuate; together very feebly sinuate at apex; disk depressed, as 

 long as wide, nearly one-half longer than the prothorax; sutural stria deep, 

 very feebly arcuate; discal fine, distinct, slightly arcuate, vanishing slightly 

 before the middle; each elytron with an isolated basal fovea near the sutu- 

 ral; surface very feebly, sparsely punctate. Abdomen as long as the elytra 

 and distinctly narrower; sides straight and parallel; border narrow; surface 

 feebly convex, finely, feebly and not densely punctate; first three visible 

 dorsals equal in length; first two each impressed in the middle of the base;

The tarsal claw has a very minute hair-like appendage 

 internally near the base, giving the appearance of a rudi- 

 mentary second claw, but as all the characters are precisely

 believe that it belongs to a different group. I would pre- 

 fer rather to consider this a tendency to revert to the nor- 

 mal condition of Coleoptera, and to hold that similar ap- 

 pearances may occasionally be exhibited in the European 

 genus. 



The type is a male, the sixth segment being deeply im-
