nine miles northwest of Blocksburg, Humboldt County, Calif., and 

 to the elevation of 2200 feet. 



Remarks. — Hatch's (1936) description of "fenyesi" is a composite 

 drawn from specimens of inopinus and cochlearis. The name fenyesi 

 is not a synonym of the name injernalis. 



6. Pterostichus (Leptoferonia) fenyesi fenderi, new subspecies 



Figures 6, 35 



Holotype male. — Same as description of fenyesi and the fenyesi 

 group, plus the following. 



Pronotum. — Sides more arcuate than in fenyesi fenyesi; ratio of 

 length to width 0.91. 



Sixth abdominal sternum of male (fig. 6). — Apical edge thick- 

 ened, but lobe nearly obsolete. 



Aedeagus (fig. 6) . — Compared with fenyesi fenyesi sensu stricto, 

 right paramere smaller, narrower, not so evenly tapering at tip. 

 Median lobe with ventral surface more concave; ventral surface and 

 right side meeting more abruptly to form a low carina that extends 

 to middle of base of ventral surface; in lateral view, right side bisinu- 

 ate; tip sharper. Internal sac apparently identical. 



Length of body. — 7.0 mm. 



Allotype female. — Same as male except ratio of pronotal length 

 to width 0.90, and usual female differences. 



Variation. — The 19 other specimens measured have the pronotal 

 ratio 0.88-0.92, median 0.91, in males; ratio 0.85-0.94, median 0.89, 

 in females. Length of body 6.0 to 7.5 mm. 



Type.— USNM 69600. 



Type-locality. — Two miles northwest of Petrolia, Humboldt 

 County, Calif. 



Specimens examined. — 21. 



Distribution (fig. 35). — Holotype, male, and allotype, female, 2 

 miles northwest of Petrolia, T. 1 S, R. 2 W, Humboldt meridian, 

 elev. 200 ft., Humboldt County, Calif., Jan. 26, 1962, H. A. Hacker. 

 Also the following paratypes: 2 males, 2 females, same data as holo- 

 type; 1 male, 1 female, 1 mile south of Capetown, T. 1 N, R. 3 W, 

 elev. 500 ft.; 1 male, 2 females, 9 miles southwest of Ferndale, T. 2 

 N, R. 2 W, elev. 1100 ft.; 1 male, 1 female, 7 miles southwest of 

 Ferndale, T. 2 N, R. 2 W, elev. 1400 ft. Eight other specimens came 

 from localities farther to the south; only a single female is known 

 from the southernmost locality, Russian Gulch, Mendocino County. 



Remarks. — The differences between this subspecies and fenyesi 

 fenyesi sensu stricto are differences in degree rather than in kind. 

 The sample examined was not large, only 57 specimens of the two
