no. 3649 LEPTOFERONIA — HACKER 29 



with tibia of middle leg with about five tubercules along inner margin, 

 giving a saw-toothed appearance. 



Sixth abdominal sternum (fig. 14). — Males with apical edge 

 thickened; carina before truncate edge about straight, sometimes 

 interrupted in middle; large impression to right of center on face. 

 Females with apical margin sub truncate; often a small impression 

 on face; a slight bulge or low carina before apical margin in linearis 

 type and a few others. 



Aedeagus (fig. 14). — Right paramere short, bulbous. Median lobe 

 smaller in proportion to body than in most other Leytojeronia; twisted; 

 basal portion with ridge where parameres meet when folded; tip small, 

 shallow, barbed at right; lightly sclerotized strip present. Internal 

 sac with small, lightly sclerotized tooth in gonopore. 



Length of body. — 7.0 to 8.5 mm. 



Variation. — As noted above, specimens from north of San Fran- 

 cisco Bay show a tendency to lose the scutellar and tarsal setae. 

 There is geographical variation among specimens from the southern 

 part of this species' range. Thirteen specimens from the Carmel, 

 Monterey County, area differ from more northern specimens as 

 follows: eyes slightly larger; sides of pronotum more arcuate, then 

 more strongly sinuate before hind angles; anterior angles not so 

 prominent; pronotal impressions tend to be weaker; sides of elytra 

 more arcuate; scutellar puncture always present on both elytra; 

 carina on sixth sternum deeply interrupted and apical edge broadly 

 emarginate in all seven males; average size larger. Specimens from 

 Santa Cruz County exhibit these characteristics to a lesser degree; 

 of 31 specimens, 28 have scutellar setae on both elytra. The aedeagus 

 seems to be constant throughout the species' range. 



Types. — Feronia angusta Dejean, apparently lost (see Lindroth, 

 1955, pp. 10-15); Pterostichus linearis, female, MCZ!; P. crucialis, 

 male, USNM! 



Type-localities. — Feronia angusta, California; P. linearis, San 

 Francisco, Calif.; P. crucialis, Santa Cruz Mountains, Calif. 



Specimens examined. — 108. 



Distribution (fig. 38). — Specimens have been collected from five 

 miles south of Carmel, Monterey County, north to Montgomery 

 Woods State Park, Mendocino County, and east to Mount Diablo, 

 Contra Costa County. This species is sympatric with fuchsi and 

 marinensis in the northern part of its range. Three apparently normal 

 males in the California Academy of Science bear the labels "Duns- 

 muir, Siskiyou County," and "Castella, Shasta County." If they 

 are labelled correctly, this species should also be found in the eastern 

 part of the Coast Range in Lake County and northward. 



Remarks. — Dejean 's type-specimen probably was from the coats;
