658 Bembidium dorsale (1823b: 84). Type area given as “Mis- 
souri” (probably = Nebraska). In the MNP is a 9 with the fol- 
lowing green Dej. labels: (a) “dorsalis Say, in Amer. Bor.”; (b) 
“Say.” There is no doubt that this is an authentic Say specimen but, 
unfortunately, it belongs to variegatum Say, auct. Say ( 1823b, p. 89) 
regarded these two species as “very closely allied” and suggested 
that dorsale might be “a mere variety” of variegatum. A comparison 
between the two descriptions (see variegatum , below) demonstrates, 
however, that Say probably had two different species before him, 
the ones that today pass under his two names. It should therefore 
be concluded that the Paris specimen was misidentified by Say and 
it should not be used as lectotype. A $ labeled Missouri has been 
designated as neotype. It belongs to the species with straight frontal 
furrows and the microsculpture of the forebody shallow. A definite 
choice of type area (or locality) should be postponed until specimens 
from Nebraska are at hand. — Bembidion dorsale [Lth., 1963, 
P- 359]. 
660 Bembidium variegatum (1823b: 89). No type area given; 
Rivervale, N. J., designated as type loc. by Lth. (1963, p. 360). 
The name was long used for intermedium Kby. and related small 
species of subg. Notaphus. Csy. (1918, pp. 139-140) correctly re- 
established variegatum as the name for the species meanwhile renamed 
postfasciatum Ham. Say gives the same size (1/5 of an inch) for 
variegatum as for dorsale. In his rather complete description of the 
two species, three pairs of characters seem to indicate that the current 
interpretation of his names is correct : — 
dorsale (pp. 84-85) 
(a) “thorax green slightly tinged 
with cupreous” 
(b) “elytra whitish-testaceous — 
two fuscous, obsolete, un- 
dulated bands behind the 
middle, the posterior one less 
definite” 
(c) (elytra with) “interstitial 
lines (= intervals) hardly 
convex” 
variegatum (p. 89) 
“thorax blackish, slightly bronzed, 
tinged each side with green” 
“elytra black variegated with tes- 
taceous, or testaceous varied with 
black dots and lines” 
(elytra with) “interstitial lines 
convex” 
A c? from Rivervale, N. J., designated as neotype of variegatum. —

694 Bembidium contractum (1823b: 85). No type area given; 
Ipswich, Mass., designated as type loc. by Lth. (1963, p. 372). Say’s 
description is quite insufficient for a species belonging to this ex-
