INSECTS COLEOPTERA. 



CONONOTUS Lec. 



C. sericans, testaceus, subtiliter confertissime punctulatus, griseo pubescens, thorace latitudine 

 apicali sesqui longiore, postice regulariter valde augustato, utrinque truncate, elytris elongato 

 ellipticis, parum convexis. Long. 13. Tab. II, Fig. 3.

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 transverse, 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 stride 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 punctate, ore clypeoque 

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

 bisinuato, angulis posticis rectis, subtiliter punctate ; elytris striis punctulatis, inter stitiis 

 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 antrorsuni 

 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 Irete fulvis nitidis leevigatis, illo basi subemarginato, ante 

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