as neotype : a $ from Rumney, N. H. — Agonum extensicolle s. str. 
[Lth., 1966, p. 625]. 
1523 Feronia decora (1823b: 53). No type area given; Arling- 
ton, Mass., designated as type loc. by Lth. (1966, p. 629). Say’s 
description fits both decorum auct. and thoracicum Dej., but the 
latter, more southern species was probably not available to him. A 
cT from Arlington, Mass., designated as neotype. — Agonum decorum 
[Lth., 1966, p. 629]. 
1 53 7 Feronia errans (1823a: 147). Type area not given but 
collected during the “Rocky Mountain Expedition” ; Buena Vista, 
Colo., designated as type loc. by Lth. (1966, p. 616). Say’s descrip- 
tion, notably of color characters, is almost decisive. A $ from Buena 
Vista, Colo., designated as neotype. — Agonum errans [Lth. 1966, 
p. 616]. 
1540 Anchomenus collaris (1834: 421). Type area Indiana. There 
are several details in Say’s description contradicting the current in- 
terpretation of his name: (a) the size is too large (7/20 of an inch, 
i.e. the same as given for placidum ) ; (b) “body black,” no mention 
made of the pale margins of prothorax; (c) “base of the first joint 
of the antennae — black-piceous,” actually the entire 1. segment is 
rufous; (d) the prothorax is described as “subquadrate,” with pos- 
terior angles “very obtuse” and basal foveae “slightly rugous” ; 
actually the prothorax is almost circular, with obliterated hind-angles 
and smooth foveae. The entire description fits melanarium Dej. much 
better. In spite of this, in the interest of stability, I have followed 
Lec.’s interpretation, according to his collection (MCZ). A cf 
from Woodbury, N. J., designated as neotype. — Agonum collare 
[Lth., 1966, p. 612]. 
1542 (? syn) Feronia scutellaris (1823a: 146). No type area 
given but collected during the “Rocky Mountain Expedition.” The 
description is quite uninterpretable and. though Lee. (1879, p. 56) 
referred it to Agonum melanarium Dej. (1828), before which it 
would then have priority, it is better to treat scutellare as a nomen 
dubium. No neotype should be selected. 
1 5 5 3 Feronia cupripennis (1823b: 50). No type area given; W. 
Roxbury, Mass., designated as type loc. by Lth. (1966, p. 591). 
Say’s description of the color pattern is sufficient for an identification. 
A 9 from W. Roxbury, Mass., designated as neotype. — Agonum 
cupripenne [Lth. 1966, p. 591]. 
1558 Feronia nutans (1823b: 52). Say’s information “bought in 
New York” is of course no base for fixation of type loc.; Philadel- 
phia Neck, Penn., designated as such by Lth., (1966, p. 617). The
