 Long. "25. 



One specimen from San Francisco, given me by Mr. Wild. Smaller and narrower than 

 H. arcuatus, to which it is allied. The thighs are entirely black, and the posterior tibiaj are 

 more compressed. The sutural stria is entirely wanting, and the epipleurfe are marked with a 

 single lateral stria ; the pygidium is ecLuably and coarsely punctured. 



Saprinus Leach. 



S. estriatus, oblongo-rotundatus, seneo-niger, thorace confertissime aciculato, callo utrinque 

 rotundato, spatioque basali sublaevibus, elytris confertissime aciculatis striis dorsalibus nullis, 

 macula pone basin subsuturali altera humerali tertiaque intermedia minore nitidis Ia3vibvi8, 

 stria externa elongata flexuosa parum distincta. Long. "IS. 



One specimen from Oregon, collected by Dr. Townsend. This species belongs with S. fra- 

 ternus, mancus, bigemmeus, &c., to group 8 of my division of the genus, (Proc. Acad. Nat. 

 Sc. 6,) in which the front is transversely margined and angularly impressed, and the prester- 

 num compressed with the striae distinct. The anterior tibiaj were probably four-toothed, as in 

 S. bigemmeus, but the teeth, with the exception of one at the middle are entirely worn oif. 



Teretkius Er. 



T. ohUquulus, oblongus, cylindricus, niger nitidus punctatus, elytris striola obliqua ad basin 

 versus humeros impressis ; antennarum clava, pedibusque piceo-rufis, tibiis anticis subito 

 dilatatis, sexdenticulatis. Long. "13. 



Sacramento ; Mr. Wittick. This species resembles in form T. picipes, but is considerably 

 larger, being fully twice as long ; that species is more finely punctured, and has no oblique 

 stria at the base of the elytra. 



Epuraea Er. 



E. nubila, elongato-ovalis, testacea, punctulato-rugosa, subtiliter flavo-pubescens, thorace 

 antrorsum angustato, lateribus rotundatis depressis, angulis posticis subrectis, elytris anguste 

 marginatis, macula utrinque ad medium nigro-picea ornatis, ad apicem singulatim rotundato- 

 truncatis. Long. '10. 



One specimen, San Jose, California. This species is a little wider than E. 2}ciraUela Lee, 

 but is narrower than usual ; the thorax is about twice as wide as its length ; the base is 

 broadly rounded in the middle, and slightly sinuate towards the basal angles, so that the 

 latter become nearly rectangular, and not rounded. The elytra are about one-half longer 

 than wide. 



Omosita Er. 



0. inversa, nigra, opaca, subtiliter griseo-pubescens, confertim subtilius punctata, thorace 

 piceo-rufo, latitudine plus duplo breviore, antrorsum magis angustato, lateribus rotundatis' late 

 depressis, disco canaliculato et utrinque subfoveato, elytiis testaceis, macula utrinque basali,
