San Jose, and San Diego, Californiaj under stones. This genus is allied to Apocrypha, but 

 the form is very different. 



Ntctibates Esch. 



N. serrata, atra opaca, capita thoraceque confluenter punctatis, hoc transverso, cordate 

 lateribus valde rotundatis pone medium subserratis, postice angustato, angulis posticis acutis 

 prominulis ; elytris thorace latioribus fortius punctato-striatis, dense punctatis ; tibiis rectis,

Oregon. Nearly allied to a nondescript found in the northern Atlantic States, but differs by 

 the less coarse punctures of the head and thorax, as well as by the latter being much narrowed 

 towards the base. The punctures of the strife of the elytra are finer and more closely placed. 

 This genus may be distinguished from its allies by the mentum being transverse, broader 

 anteriorly, and obtusely rounded, flat or slightly concave. 



Plattdema Laporte. 



P. oregonense, ovale convexum, nigrum nitidum, capite subtiliter punctato, ore clypeoque 

 rufo-piceis, thorace brevi antrorsum angustato, lateribus marginatis vix rotundatis, basi 

 bisinuato, angulis posticis rectis, subtiliter punctato ; elytris striis punctulatis, interstitiia 

 paulo convexis disperse subtiliter punctulatis, epipleuris piceis ; pedibus antennisque ferrugineis, 

 his articulo ultimo pallidiore. Long. •22. 



Fort Vancouver, Colonel McCall. The elytra are slightly dilated from the base nearly to 

 the middle, then gradually narrowed and rounded. 



Phaleria Latr. 



P. globosa, rotundata convexa, testacea, capite thoraceque confertim punctatis, hoc antrorsum 

 angustato, lateribus valde rotundatis, ad basin utrinque striola brevissima notato ; elytris pro- 

 funde striatis, interstitiis confertim rugosis et punctatis, guttis parvis ad basin versus 

 scutellum, maculis duabus ante medium linea angulata connexis, alteraque ad dodrantem 

 nigris ; postpectore abdomineque obscuris ; antennis ultra thoracis basin extensis. Long. '12.

San Francisco, given me by Mr. J. P. Wild. Seems to resemble P. picta, but the thorax 

 of that species is said to have two basal striae each side, and only one elytral black spot. 



Lttta Linn. 



L Cooperi, atra capite thoraceque laete fulvis nitidis laavigatis, illo basi subemarginato, ante 

 oculos nigro, hoc pentagonali, latitudine breviore, angulis lateralibus acutis, dorso deplanato ;
