[September 
ceedingly difficult group. In the Paris Museum is a $ with small 
green Dejean label, with “Say” only; although it stands under the 
label “ contraction” in the drawer, its character of a. true representative 
of what Say regarded as his contractual may perhaps be questioned. 
The specimen does not belong to contractum auct. (Lth. 1963, p. 
372). The wings are full (in contractum apparently constantly re- 
duced) and, above all, the hind-angles of its prothorax are very 
poorly developed, exactly as described for vernacula Csy. (1885). 
This was regarded as a sbsp. of constrictum Lee. by Casey 1918 
(p. 124) but it is a doubtless distinct species. In view of the incom- 
plete labeling of the Paris specimen and also of the considerable 
confusion that would be created by a removal of Say’s name, I have 
refused to designate it as leototype. A cf of the “true” contractum 
from Ipswich, Mass., has been designated as neotype. — Bembidion 
contractum [Lth. 1963, p. 372]. 
705 Bembidium affine (1823b: 86). No type area given; Mobile, 
Ala., designated as type loc. by Lth. (1963, p. 376). Say’s descrip- 
tion does not exclude members of the versicolor group but his name 
has always been used for the only species with frontal furrows 
doubled both in front and behind. It was later described by Dej. 
(1831) as decipiens and fallax. A cf from Mobile, Ala., designated 
as neotype. — Bembidion affie [Lth., 1963, p. 376]. 
737 (syn.) Bembidium oppositum (1823b: 86). No type area 
given; Rumney, N.H., designated as type loc. by Lth. ( 1963, p. 383). 
Say mentions the laterally oblique base of the prothorax and, in 1834 
(p. 439), suggests that his species belongs in (subg.) Lopha ; the 
interpretation, therefore, seems certain. Lee. (1859b, p. 501) de- 
clared oppositum as identical with quadrimaculatum L., but it is now 
regarded as a Nearctic subspecies of this (Lth., 1 . c.). A cf from 
Rumney, N. H., designated as neotype. — Bembidion quadrimacula- 
tum oppositum [Lth. 1963, p. 383]. 
792 Bembidium ephippiatum (1834: 439). Type area Indiana. 
Say’s description is conclusive. A cf from Indiana (coll. Fall) 
designated as neotype . — Tachys (Pericompsus) ephippiatus [Hayw. 
1899, p. 214]. 
805 Bembidium incurvum (1834: 440). Type area Indiana. 
Though Say’s description of the head as “blackish-piceous” points 
to incurvus auct. rather than to the closely allied anceps Lee., it is by 
no means decisive. I have followed Lee., acc. to his collection (MCZ). 
A cf from N. Illinois (coll. Fall) designated as neotype. — Tachys 
incurvus [Lth. 1966, p. 416]. 
829 Bembidium tripunctatum (1834: 439)- Type area Indiana.
