San Jose, and San Diego, California, under stones. This genus is allied to Apocrypha, but 
the form is very different. 
Nyctibates Esch. 
N. serrata, atra opaca, capite thoraceque confluenter punctatis, hoc transverso, cordato ? 
lateribus valde rotundatis pone medium subserratis, postice angustato, angulis posticis acutis 
prominulis ; elytris thorace latioribus fortius punctato-striatis, dense punctatis ; tibiis rectis, 
antennis breviusculis. Long. '9. Tab. II, Fig. 5.

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 striae 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. 
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 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. 
Lytta Linn. 
L Cooperi, atra capite thoraceque laete fulvis nitidis laevigatis, illo basi subemarginato, ante 
oculos nigro, hoc pentagonali, latitudine breviore, angulis lateralibus acutis, dorso deplanato ;
