Camaguey, “Aug.- Sept.,” J. M. Osorio (Collection of Esta-

The Cuban subspecies differs from true Agonum extensi- 
colle (Say) of the eastern United States, and from practi- 
cally all other forms of the species occurring on the conti- 
nent north of Mexico, in having the legs infuscate, not tes- 
taceous. From Mexican specimens and others with brown 
legs the Cuban ones differ in the much brighter green head 
and prothorax.
