Platynus reflexus, Lec., and variety a.— This species may be found in the bed of nearly dry hill-side streams and the debris along theri banks, June being the time of its greatest abundance. In Dr. Leconte's synopsis of Platynus (Bull. Brook. Ent. Soc., Il.,) a variety in noted as a, with four elytral punctures, while reflexus has but three—nothing further being stated. This form occurs here, not as an individual variation, but at least as a race, perhaps a species.
