Found in every part of California. Belongs to the division of the genus which contains 

 most of the North American species of Acupaljjus described by Dejean ; the tarsi of the male 

 are hardly dilated. 



Promecognathus Chaud. 



P. laevissimics, niger, nitidissimus, mandibulis porrectis, capite haud brevioribus, capite 

 utrinque bistriato, thorace latitudine longiore, postice angustato, et lateribus subsinuato, angulis 

 posticis subobtusis, ad basin marginato, et utrinque subfoveato, elytris thorace latioribus, ovali- 

 bus postice valde declivibus. Long. •43 — ^"46. Tab. I, fig. 4.

Eripus laevissimus Dejean, Sp. Gen. 4, 11 : Mann. Bull. Mosc. 1843, 210. 



San Jose, California, on rocky hills, under stones. I have failed to perceive any relation- 

 ship between this genus and Stomis, near which it is placed by Baron Chaudoir. By the form 

 of the mentum and labrum, as well as by the structure of the antennae, it seems closely allied 

 to Pasimachus and Scarites, although differing by the anterior tibiae, which are not palmate. 



Ctchrus Fabr. 



C. tuberculatus, ater, opacus, capite valde rugose punctato, piano, lateribus subcarinatis, 

 fronte late bisulcato, et medio elevate, thorace profunde confluenter punctato, ad apicem et basin 

 truncate, postice angustato, angulis posticis obtusis, ad basin transversim impresso et utrinque 

 foveato, elytris ventricosis, tuberculis parvis nitidis obsitis, tuberculisque maioribus serie triplici 

 positis, quarum tuberculo intermedio postice maier. Long. '88. Tab. I, fig. 6.

A specimen collected in Oregon by the late Dr. J. K. Townsend was given to me by Mr. 



Willcox. 



Carabus Linn. 



C. taedatus, niger, thorace latitudine breviore, minus convese, postice subangustate, lateribus 

 antice rotundatis^ pone medium anguste reflexis, angulis posticis modice productis ad apicem 

 rotundatis, disco parcius lateribus et basi dense punctato et intricato-rugoso, elytris saepe piceo- 

 purpureis, thorace sesqui latioribus, elongatis, subtiliter dense striolato-punctatis, foveisque 

 magnis minus profundis, serie triplici impressis. Long. -92. Tab. I, fig. 7.
