Ventral surface. — Scattered coarse punctures on thorax, density 

 variable. 



Legs. — Hind trochanter blunt, short, about one-third the length 

 of hind femur; legs long and slender; three pairs long setae present 

 on ventrolateral margins and three pairs on dorsal surface of last 

 article of tarsus. 



Sixth abdominal sternum of male (fig. 26). — Unmodified. 



Aedeagus (fig. 26). — Right paramere cylindrical, slightly elongate. 

 Median lobe broad, almost symmetrical; no well-defined strip. 

 Internal sac without sclerotized tooth. 



Length of body. — 7.0 to 9.0 mm. 



Type.— Male, CAS 1826! 



Type-locality. — Marshfield [now Coos Bay], Coos County, Oreg. 



Specimens examined. — 12. 



Distribution (fig. 33). — All specimens except one (Carpenterville, 

 elevation 1700 feet) came from elevations near sea level. They were 

 collected from a variety of habitats including a dense forest of Picea 

 sitchensis (Bong.) Carr., sandy soil under bushes adjacent to the 

 seabeach, sea dunes, and a stream, and in open woods of Pseudotsuga 

 menziesii (Mirb.) Franco, Arbutus menziesii Pursh, and Quercus 

 species. 



Remarks. — This species keys out to Agonini or Licini [sic] in Hatch 

 (1953, p. 70) because of its short hind trochanters, emarginate labrum, 

 and short clypeus. The teeth on the mandible and the setae on the 

 maxillary palpus probably do not occur in any other species in the 

 Leptoferonia-Hypherpes-Anilloferonia complex of Pterostichus. A new 

 subgenus should be established for termitiformis. 



Summary 



The original purpose of this paper was to redescribe several species 

 about which there had been some confusion. In the course of the 

 study, 10 new forms were discovered. Seven of these are described as 

 new species and three as new subspecies. 



Sixteen species from western Oregon and California were the main 

 subjects of study. The geographical ranges of these species are now 

 fairly well known and are shown on distribution maps. 



I have used the subgeneric name Leptoferonia in its traditional 

 sense. I do not believe that all 21 species now included in the subgenus 

 have a common immediate ancestor. Perhaps when the whole genus 

 Pterostichus and especially the subgenus Hypherpes are revised, the 

 subgenus Leptoferonia will be redefined to include fewer species. 



Future studies of chromosomal karo types, immature forms, and 

 zoogeography may help to clarify the relationships within Leptoferonia 

 and between Leptoferonia and Hypherpes.
