 on ventral surface at edge; one or two impressions on face. 



Aedeagus. — Right paramere elongate; lobe present, beneath and 

 parallel to long distal portion. Median lobe narrowed distally; tip 

 short; lightly sclerotized strip across distal portion. Internal sac with 

 two adjacent, sclerotized, flexible lobes, one surrounding gonopore, 

 other more or less mushroom shaped.

 Pterostichus (Leptoferonia) fenyesi. — Hatch, 1936, p. 704 [in part; not Csiki, 1930, 



p. 582]. [New synonymy.] 



Species description. — Same as description of inopinus group plus 

 the following. 



Head. — Frontal impressions forming an angle greater than 45°, 

 converging posteriorly; area on inner side of impressions distinctly 

 flattened; microreticulate. 



Pronotum. — Sides from slightly arcuate to slightly sinuate in 

 vicinity of posterior setiferous punctures, in former case hind angles 

 less distinct; transverse basal impression complete in about 25 speci- 

 mens, reaching only to longitudinal basal impressions in about 25 

 specimens, intermediate in 210; single pair of longitudinal impressions 

 not deep, usually not reaching basal margin; disc microreticulate. 



Elytron. — Humeral dentation small, sometimes acute; setiferous 

 punctures on eighth stria consisting of six in anterior series, sixth 

 frequently detached, none intermediate, seven in posterior series; 

 two setae at posterior end of seventh stria; microreticulate. 



Ventral surface. — Coarse punctures confined to mesepisternum; 

 prosternal tip completely margined in only about 60 specimens. 



Sixth abdominal sternum of male (fig. 1). — Large, truncate, 

 ventrally curved lobe at edge; face with two impressions separated 

 by curved carina, right impression larger than left. 



Aedeagus (fig. 1). — Right paramere with lobe beneath distal 

 portion small, evenly arcuate; nearly cylindrical distal portion very 

 long, with 90° bend near tip. Median lobe with tip shallow and blunt; 

 lobe on right side large, its highest part a ridge down inner side. 



Length of body. — 7.0 to 8.5 mm. 



Variation. — Specimens from south of about the middle of Douglas 

 County, Oreg., have a variable second bend in the right paramere 

 of the aedeagus. Specimens from the coast are uniformly small; 

 the minimum length of noncoastal specimens is 7.5 mm.
