Piesmus monedulus Germar (submarginatus Say). Tallahassee, 
Chuluota (Schwarz); Pensacola (Slosson Coll.); Ormond, March, April, 
beneath bark of pine logs (Blatchley); Taylor Co., January, March (Ge- 
nung). Confined to Southern States, Mobile and Baldwin Co., Ala., under 
bark of pine and oak (Léding). 
Casey (Memoirs IV, 1918, p. 143) restricts the name submarginatus to 
specimens from North Carolina, in which the strie are coarse, moderately 
impressed, distinctly but not extremely punctured, and calls the Florida 
specimens with distinctly shorter elytra, the striae of which are extremely 
coarse, in fact sulciform, and still more coarsely and conspicuously punc- 
tured, monedulus Germar. Germar’s name having priority by about a year 
would also take precedence of Say’s if Casey’s view were not acceptable. 
The species ventralis Say (cycloderus Chaudoir), obscurus Say and tum- 
escens Lec. differ so widely by the coarse punctuation of the under surface 
that they may require a new genus. Though they constitute a separate 
section “ B” in Schaupp’s synopsis, the distinguishing character does not 
receive sufficient prominence, and “ abdomen punctate”? might with ad- 
vantage be added to 18th line on p. 28, following the words “ scutellar 
stria short.”’ : 
?Pterostichus ventralis Say. ‘‘ Fla.” (Bull. Br. Ent. Soc., v. p. 41). 
There is no confirmation of this record and the known distribution does not 
support it. Occurs also in Louisiana, Kansas, Missouri. 
Ferestria n. gen. 
The four species that follow, with approximatus, constitute a section of 
the tribe Pterostichini, which looks very different from the remainder on 
account of the more or less complete absence of the elytral striee. I propose 
to separate them under a new genus, named Ferestria and defined as follows: 
Thorax strongly rounded in front of the sides, deeply sinuate behind, with small 
but distinct rectangular hind angles in some species, obtuse hind angles in others: 
elytra short, scarcely half as long as body, with the external stris: more or less obso- 
lete, all the strie feebly impressed, and one dorsal puncture behind the middle; 
each ventral segment with two distant setigerous punctures near hinder margin; 
designating Pterostichus levipennis Lec. as the type, since in that species the char- 
acters which isolate the new genus are most marked. 
Ferestria obsoleta (Say). Tampa, in the pine woods under sticks, 
rare (Schwarz); Gulf Hammock (Castle and Laurent); Key West (Angell 
Coll.). Described from Indiana, known also from Illinois, Ohio, and Texas. 
Found by Léding only in northern Alabama.
