1489 Feronia impunctata (1823b: 45). Type loc. Germantown, 
Penn. Say’s description seems sufficient for an identification. It is 
very puzzling that Dejean (1828, p. 469), from 1 ex. sent by Say, 
regarded Feronia impunctata as a synonym of Amara familiaris Dft. 
This cannot be a lapsus calami for Feronia imp.uncticollis (see above) 
because the latter was by Dejean ( 1 . c., p. 464) synonymized with 
Amara trivialis Gyll. (= aenea DeG.). A <S from Tyngsboro, 
Mass., designated as neotype. — Synuchus impunctatus [Lth., 1966, 
P. 55 i]. 
1507 Feronia hypolithos (1823b: 59). No type area given; Cleve- 
land, Ohio, designated as type loc. by Lth. (1966, p. 645). Only 
size and the expression “striae — irregularly punctured” suggest 
hypolithos auct., which was otherwise interpreted from coll. Lee. 
(MCZ). A cT from Cleveland, Ohio, designated as neotype . — 
Agonum hypolithos [Lth., 1966, p. 645]. 
1513 Feronia decentis (1823b: 53). No type area given; Marion, 
Mass., designated as type loc. by Lth. (1966, p. 636). Say’s descrip- 
tion of the prothorax makes it almost certain that he had the “true” 
decentis before him ; the pronounced sinuation of sides in front of the 
denticulate hind-angles, in sinuatum Dej., could hardly have remained 
unnoticed by Say. Therefore, a pronounced decentis s. str. (a $) 
has been selected as neotype. — Agonum decentis [Lth., 1966, p. 636]. 
1518 Feronia cincticollis (1823b: 52). No type area given; 
Philadelphia, Penn., designated as type loc. by Lth. (1966, p. 640). 
Say’s description is insufficient. His name has been interpreted ac- 
cording to coll. Lee. (MCZ). A from Philadelphia, Penn., 
designated as neotype. — Agonum cincticolle [Lth., 1966, p. 640]. 
1518 ( ? syn.) Feronia maculifrons (1823a.: 146). Type area “Ar- 
kansa Territory.” The description cannot be interpreted and the name 
has never been used (see Lee., 1854, pp. 43, 59; 1859a, p. 94). It 
should be treated as a nomen dubium (Lth., 1966, p. 640) and no 
neotype selected. 
1522 Feronia extensicollis (1823b: 54). No type area given; 
Rumney, N. H., designated as type loc. by Lth. (1966, p. 625). 
That Say’s description refers to extensicolle auct. can hardly be 
doubted. However, since this species shows considerable geographical 
variation (Lth., 1966, pp. 625-627) and because Say did not mention 
the provenience of his specimens, it is of special importance to select 
a type area. Lee. (1854, P- 46) regarded the eastern, Casey (1920, 
p. 57) the western form as the true extensicolle. Say’s material was 
probably from Pennsylvania, and it is therefore advisable to follow 
Lec.’s opinion. A pronouncedly “eastern” specimen was designated
