Platynus crenistriatus, Lec. I took a speciment of this interesting little beetle (fig.1) here late in October, at the foot of a stump. It is not unlike in October, at the foot of a stump. It is not unlike in appearance certain small Pterostichi but may be at once distinguished by having the elytral margin behind sinuate and simple, without the interruption and route fold usually seen in Pterostichus. It seems to me to be, in fact, one of those less specialized forms still exhibiting characters in common with some species of that genus.
