no. 3649 LEPTOFERONIA — HACKER 19 



subspecies, of which 29 were males. The characteristics separating 

 the two do not seem to undergo clinal variation within the two groups. 

 The two groups are not known to overlap or to intergrade in mor- 

 phological characteristics along their common boundary (see fig. 35). 

 Not many specimens are known from the boundary area, but it 

 does seem likely that no more than a small area of intergrading might 

 exist. When more specimens have been collected from the boundary 

 area, the status of the two groups will be resolved. I think it is safe 

 to consider the two populations to be at least separate subspecies. 

 I take pleasure in naming this subspecies for Mr. Kenneth M. 

 Fender. 



7. Pterostichus (Leptoferonia) cochlearis, new species 



Figures 7, 35 



Holotype male. — Same as the description of fenyesi group plus 

 the following. 



Pronotum. — Midline not abruptly impressed, surface adjacent to 

 midline tumid; ratio of pronotal length to width 0.93. 



Sixth abdominal sternum of male (fig. 7). — Apical margin 

 thickened and produced into well-defined and ventrally directed lobe. 



Aedeagus (fig. 7). — Right paramere relatively large and bulbous. 

 Median lobe broad; ventral surface slightly concave; right side and 

 ventral surface not meeting sharply; tip blunt, rounded, not directed 

 to left; internal sac with sclerotized lobe and tooth not the same shapes 

 as in fenyesi. 



Length of body. — 8.0 mm. 



Allotype female. — Same as holotype except pronotal ratio 0.88, 

 and usual female differences. 



Variation. — The 75 other specimens measured have the pronotal 

 ratio 0.86-0.96, median 0.91, in the males; 0.84-0.92, median 0.89, in 

 the females. Length 7.0 to 8.5 mm. In Oregon males, the lobe of the 

 sixth sternum tends to be defined less abruptly and to be slightly 

 emarginate in the middle. Variation in the pronotal ratio does not seem 

 to be clinal.
