Besides the three-punctured base of prothorax, Say mentions the 
presence of five elytral striae, which makes his description almost 
decisive. A <$ from New Jersey designated as neotype. — Tachys 
tripunctatus [Lth. 1966, p. 423]. 
849 Bembidium proximus (1823b: 88). No type area given; 
Brookline, Mass., designated as type loc. by Lth. (1966, p. 432). 
The description of the prothorax (“posterior angles rectangular”) 
fits rhodeanus Csy. at least as well, and also scitulus Lee., but I pre- 
fer to follow current practice, as expressed in coll. Lee. (MCZ). A 
9 from Brookline, Mass., designated as neotype. — Tachys proxi- 
mus [Lth. 1966, p. 432]. 
883 Bembidium laevum (1823b: 88). No type area given; Ar- 
lington, Mass., designated as type loc. by Lth. (1966, p. 426). The 
small size (“one-twentieth of an inch”) and the presence of only one 
impressed elytral stria, mentioned by Say, make the interpretation 
almost decisive. A 9 from Arlington, Mass., designated as neotype. — 
Tachys laevus [Lth. 1966, p. 426]. 
892 Bembidium inornatum (1823b: 87). No type area given; 
Asheville, N. C., designated as type loc. by Lth. (1966, p. 436). 
Say’s name has been associated with the North American form of 
subg. Tachyta lacking a carina inside hind-angles of prothorax. 
Though Say does not mention this character, the procedure may be 
defensible. The taxonomic position of this form is much disputed : 
whether a separate species (Csy., 1918), a subspecies (Lth., olim), 
or a form of nanus Gyll. not deserving a name (Lth., 1. c.). A <$ , 
without prothoracic carina, from Asheville, N. C., designated as 
neotype. — Tachys nanus Gyll. [Lth., 1966, p. 436]. 
898 Bembidium flavicaudus (1832b: 87). No type area given; 
White Sulphur Springs, W. V., designated as type loc. (Lth., 1966, 
p. 441). Say fails to mention the peculiar structure of the prothorax, 
but color characters as well as the reported occurrence under bark 
seem sufficient for an identification. A from White Sulphur 
Springs, W. V., designated as neotype. — Tachys (T achymenis) flavi- 
cauda [Lth., 1966, p. 441]. 
901 Feronia longicornis (1832b: 40). No type area given; Ar- 
lington, Mass., designated as type loc. by Darlington (1938, p. 158) 
who labeled a cf from the same place as neotype. — Fatrobus longi- 
cornis [Lth., 1961, p. 180]. 
929 Abax coracinus (1823b: 59). No type area given; Rocke- 
ville, Penn., designated as type loc. by Lth. (1966, p. 444). The 
only character mentioned by Say pointing to coracinus auct. rather 
than to cyanescens Dej. ( foveatus Lee.) refers to the elytral striae
