fertissime punctato distincte canaliculato, elytris parallelis, rugose punetatis, 
subtiliter striatis. Long. -2. One female, Pennsylvania. Differs from the last 
by its coarser und denser punctuation, and by the thorax not being regularly 
narrowed in front.

Spherocephalus Esch. 
This genus has a very great resemblance, to the last, and can only be distin- 
guished by the slight inferior prolongation of the fourth tarsal joint, and by the 
prosternal prominence being acute. In the last genus this prolongation is blunt 
and rounded. ‘The males of this genus have the 6 last joints of the antenne a 
little enlarged.

subtilissime fulvo-pubescens, fronte linea tenuissima levi, thorace latitudine

Georgia : in Say’s description of the preceding species, probably by a ¢ clerical’ 
error, the terminal, instead of the penultimate joint of the tarsi is said to be di- 
lated.

Guérin refers this genus to the genuine Elateride: Erichson in Agassiz’ No- 
menclator Zoologicus places it in Cebrionide. The form of the clypeus, how- 
ever, forces it into the present group. The prosternum is scarcely prominent 
behind; the plates of the posterior coxe are suddenly dilated, by the addition 
of a quadrangular piece. 
2. A. Latreillei, obscure rufo-piceus, subnitidus, thorace convexo, sub- 
tiliter parce granulato, postice canaliculato, lateribus valde rotundatis, angulis 
posticis divergentibus, elytris profunde striatis, interstitiis subtiliter rugose 
punctatis. Long. -4—-5. Sacramento, California, Rathvon. ‘i 
The thorax is much more rounded on the sides than in A. Druryi, and the 
whole surface is muchless scabrous ; the head is more distinctly granulated than 
the thorax, and the frontal line is faint as in the other species.
