8an Jose, and San Diego, California, under stones. This genus is allied to Apocrypha, but 

 the form is very different. 



Ntctibates Esch. 



N. serrata, atra opaca, capite thoraceque confluenter punctatis, hoc transverso, cordato 

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

 promiuulis ; elytris thorace latioribus fortius punctato-striatis, dense punctatis ; tibiis i-ectis,

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

 the less coarse i^unctures of the head and thorax, as well as by the latter being much narrowed 

 towards the base. The punctures of the stria3 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, fiat or slightly concave. 



Platydema 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, interstitiis 

 paulo convexis disperse subtiliter punctulatis, epipleuris piceis ; pedibus antennisc[ue 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. glohosa, 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 strife each side, and only one elytral black spot. 



Lytta Linn. 



L Cooperi, atra capite thoraceque la3te fulvis nitidis lasvigatis, illo basi subemarginato, ante 

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