tial space with three nearly equidistant punc- 
tures, the terminal one much the largest, with 
minute elevated centres ; tip very obtusely 4hu- 
ous : tom dull rufous. 
Length less than two-fifths of an inch.

Mexico with Mr. Maclure. 
It will be obvious from this description that our 
species does not well correspond with the S. pu^ 
micatusy Panz., but agreeably to the tables given 
by Dejean it cannot be placed elsewhere. It is 
larger and more dilated than pumicatus, the ba- 
sal joint of the antennse is shorter, the palpi are 
not so obtusely truncated, and its habit and ap- 
pearance quite different.

In my paper on the Carabici and Hydrocan- 
thari, published in the Trans. Amer. Philos. Soc< 
Vol. 2j new series, as above quoted, I described 
five species of the United States, under the genus 
Feronia agreeably to the arrangement of La- 
-treille, indicating, however at the same time that 
they belonged to Boiielli’s Amara. 
But Dejean and many other distinguished en- 
tomologists give the group a separate station.

The follm^ving species appear to be new.
