ameis, dense fortiter punctatis, illo linea tenui hevi antice obliterata, hoc lati- 

 tudine longiore postice paulo angustato, vitta dorsali nitida lsevi, elytris con-

San Jose, California, under bark of oak trees. The ventral segments are 

 sometimes annulate with dark red. The outer joints of the antennse are 

 slightly transverse. These three species and the next belong to Erichson's 

 8th family. 



26. Staphylinus pleuralis, piceo-niger, fusco-pubescens, capite thora- 

 ceque dense sat fortiter punctatis, illo linea tenui laevi antice obliterata, hoc 

 latitudine longiore, postice paulo angustato, vitta angusta dorsali laevi nitida, 

 scutello atro-tomentoso, elytris confertissime subtiliter punctatis, piceis, 

 lateribus late obscure rufis, abdomine supra tomento aureo irrorato, pedibus 

 rufis, coxis piceis. Long. -56 '63. 



Oregon. The punctures of the head and thorax are finer than in S. 1 u t e - 

 ip e s . The golden pubescence of the dorsal segments seems to be generally 

 diffused, so far as I can judge by the specimens before me, and there are faint 

 indications of two rows of velvety black spots. 



27. Liparocephalus b r e v i p e n n i s MaTclin, Bull. Mosc, 1853, 191. 



A specimen collected by Mr. A. Agassiz at Cape Mendocino agrees with the 

 description of this species, except that the color is dark brown, and the an- 

 tennae are not obviously shorter than the head and thorax. A compaaison 

 with a specimen from Russian America will be necessary before it will be pro- 

 per to express an opinion regarding the specific nature of these differences. 



28. Hister (Platysoma) punctiger, elongatus, parallelus, parum con- 

 vexus, niger nitidus, capite parce punctulato fronte vix concava, striola in- 

 tegra, thorace disco punctulato, lateribus parce punctatis, stria marginali ad 

 apicem ambiente, elytris obsolete parce punctulatis, apice punctis paucis, 

 notatis, 6-striatis striis internis duabus ante medium antice abbreviates (in- 

 terno longiore) punctoque basali notatis ; mesosterni stria marginali integra ; 

 pedibus piceo-rufis, tibiis anticis 4-, intermediis 3-, posticis 2-dentatis. Long.

California. Mr. A. Murray. Larger and wider than H. parallelus, and 

 much less convex, resembling in form H. sequus Lee, but much larger and a 

 little more convex.* 



Amartds. (n. g. Nitidulidae, trib. Brachypterini.) 



Palpi labiales articulo ultimo elongato, ovali ; unguiculi simplices, pygidium 

 $ segmentulo anali auctum. 



The external appearance of the species of this genus described below is that 

 of Carpophilus, and very nearly that of C. niger, but the absence of antennal 

 grooves will at once distinguish it. The outer lobe of the maxillse is long and 

 slender, not hooked at the extremity, with a large terminal vesicle. The 

 labial palpi have the first joint short, the second one half shorter than the 



*Resembling in appearance this species, but still larger and more convex, 

 with the stri<e of the elytra more distinctly punctured, and the sutural stride 

 shorter than the inner dorsal one is a species from Ohio given me by Mr. Ulke, 

 which I would name 



Hister (Platysoma) bas alis, elongatus, cylindricus, niger nitidus, capite 

 parce punctato, fronte concava, striola integra, thorace disco parce punctulato, 

 versus apicem et lateribus paulo fortius, stria marginali ad apicem ambiente, 

 elytris ad basim profunde transversim impressis, fere marginatis, 6-striatis, 

 striis punctatis, duabus internis antice abbreviatis (interno breviore); mesos- 

 terni stria marginali apice deficiente, pedibus, nigris tibiis anticis 4-, intermediis 

 posticisque 3-dentatis. Long. -20.
