INSECTS COLEOPTERA. 69 



San Jose and San Diego. Similar in form and sculpture to H. albionica; the fifth joint of 

 the antennas of the male is conical and dilated. 



PsTLLiODES Latr. 



p. parvicollis, elongatoovalis, antice angustior, aeneo-nigra, capite parce punctulato thorace 

 confertim punctato, antrorsum angustato, angulis anticis^ oblique truncatis ; elytris striato-

 sisque piceo-testaceis. Long. "09. 



San Jose, California. Of the same form as P. punctulata Mels., but with the strias of the 

 elytra deeper, more finely and closely punctured. 



P. convexior, ovalis antice angustior, aeneo-nigra, capite parce, thorace confertim punctato 

 antrorsum subangustato, angulis anticis oblique truncatis ; elytris pernitidis convexis punctato- 

 striatis, interstitiis planis parce subtilissime punctulatis ; antennis fuscis ad basin testaceis,

San Jose, one specimen. Larger and more convex than the preceding, but agreeing in form 

 with a nondescript found at Lake Superior ; it differs, however, in having the thorax more 

 convex and less narrowed in front, and the elytra more rounded on the sides. 



CiiAETOCNEMA Stephens. 



C. irregularis, oblonga, griseo-aenea, capite thoraceque fortius punctatis, hoc latitudino 

 breviore, antrorsum baud angustato, spatio parvo dorsali postico laevi ; elytris subparallelis

San Jose. Very distinct from the other species known to me, not only by the form, but by 

 the irregular confused rows of punctures of the elytra.

San Francisco. Very different from the other species known to me, by the square punctured 

 thorax. 



L. longulus, elongatus niger, thorace capiteque cyanescentibus, illo polito quadi-ato, latitudine 

 fere longiore, subtiliter praecipue versus latera punctato, angulis rectis, lateribus subsinuatis ;
