no. 3649 LEPTOFERONIA — HACKER 11 



Holotype. — Male, USNM! 



Type-locality. — Golden, Josephine County, Oreg. (T. 33 S, R. 

 5 W, Willamette meridian, elevation approximately 1600 feet). 



Specimens examined. — 266. 



Distribution, (fig. 32). — This species occurs in the central and 

 southern parts of western Oregon and extreme northwestern Cali- 

 fornia. It occurs from elevations of sea level to 4500 feet in the north 

 and probably higher in the south. Two specimens in the University 

 of Washington collection are labelled "Toppenish [Yakima County], 

 Wash.," which is probably an error. 



Remarks. — Hatch's (1936) description of "fenyesi" consists, at 

 least in part, of specimens of inopinus. The holotype of ovicollis 

 Schaeffer is not conspecific with the holotype of inopinus Casey. 

 The species inopinus can be distinguished from the other members 

 of the inopinus group on the basis of the aedeagus, or the divergent 

 and recurved frontal impressions on the head, or the entirely micro- 

 reticulate dorsum. Externally inopinus and the two species of the 

 jenyesi group are similar. In inopinus the hind angles of the prono- 

 tum are usually more prominent, the posterior setiferous punctures 

 on the pronotum not quite so far forward, and the elytral humeri 

 less rounded. 



Pterostichus (Leptoferonia) pumilus Casey 



Figure 40 



This species comprises a group of populations classified herein as 

 two subspecies: the more northern pumilus pumilus Casey, and 

 pumilus willamettensis, new subspecies. Those characteristics common 

 to all specimens of pumilus are listed below. 



Species description. — Characters of the inopinus group plus the 

 following. 



Head. — Frontal impression sharp, curved, forming an angle of 

 about 45°, divergent posteriorly; small triangular depressed area 

 on front between impressions; micros trigulose. 



Pronotum. — Sides arcuate in anterior two-thirds, from strongly 

 sinuate to slightly arcuate in vicinity of posterior setiferous punctures ; 

 single pair of longitudinal impressions deepest in middle, weakly 

 reaching to complete basal transverse impression; area between 

 longitudinal impression and side margin tumid except in area imme- 

 diately adjacent to angle; midline sharp, not reaching either edge; 

 disc microstrigulose or partly microreticulate. 



Elytron. — Humeral dentation small; setiferous punctures on 

 eighth stria consisting of six in anterior series, one intermediate, 

 eight in posterior series; two setae at posterior end of seventh stria; 

 microreticulate.
