Psyche 
[September 
pubescence, unique within the entire genus. There are 2 authentic 
9$ in MNP: (i) with two green Dej. labels: (a) “laevigata Say, 
in Amer. bor.,” (b) “D. Say”; and (2) with two green Dej. labels: 
(a) (b) “Say.” I have designated $ nr. 1 as lectotype. A 
definite choice of type area (or locality) should be postponed until 
specimens from Nebraska are at hand. It is not necessary to change 
Say’s original spelling into laevigatum . — Bembidion levigatum [Lth. 
1963, p. 254]. 
512 Bembidium niger (1823b: 85). No type area given; Rum- 
ney, N. H., designated as type loc. by Lth. (1963, p. 301). The 
name is interpreted according to coll. Lee. (MCZ). One point 
confirming this in Say’s descriptions (also 1834, p. 437) is the very 
coarsely punctate, apically obsolete elytral striae. A d from Rum- 
ney, N. H., designated as neotype. — Bembidion nigrum [Lth. 1963, 
p. 301]. 
577 Bembidium postremum (1834: 437). Type area Pennsyl- 
vania. Lee. (1859b, p. 561) first regarded postremum as the same 
as scopulinum Kby., which is easily understood, considering that Say 
described his species as smaller than tetracolum. However, current 
practice, based on Lee., according to his collection, applies the name 
postremum to the large eastern representative of the bimaculatum 
group (Lth., 1963, p. 330). There is no reason for a change. A d 
from Allegheny, Penn., has been designated as neotype and the place 
as type loc. — Bembidion postremum [Lth. 1963, P- 330 ]. 
588 Bembidium tetracolum (1823b: 89). No type area given; 
Arlington, Mass., designated as type loc. by Lth. (1963, p. 330 - 
Say’s descriptions (also 1834, p. 437) are not sufficient for specific 
recognition in this difficult group. I have followed Lee., according 
to his collection (MCZ). In N. America the species is an old intro- 
duction from Europe, where it was long, incorrectly (Lth., 1 957 > 
pp. 334-335), known as U ustulatum L.” A d from Arlington, Mass., 
designated as neotype. — Bembidion tetracolum [Lth. 1963, p. 33 1 ] * 
591 Bembidium honestum (1823b: 82). No type area given; 
Water Gap, N. J., designated as type loc. by Lth. (1963, p. 248). 
Say’s description is not decisive but it is advisable to follow Lec.’s 
opinion, as expressed in his collection (MCZ) where his own basale 
(1848, p. 454) was placed as a synonym. But antiquum Dej., re- 
ferred to as another synonym by Lee. (1859b, p. 498), belongs to 
chalceum Dej. (see Lth. 1963, p. 247). A d from Water Gap, 
N. J., designated as neotype. — Bembidion honestum [Lth. 1963, 
p. 248].
