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. 



PSYLLIODES Latr. 



P.parvicollis, elongato-ovalis, antice angustior, aeneo-nigra, capite parce punctulato thorace 

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

 punctatis, interstitiis paulo convexis punctulatis ; antennis fuscis ad basin testaceis, tibiis tar- 

 sisque piceo-testaceis. Long. 09. 



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

 elytra deeper, more finely and closely punctured. 



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

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

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

 tibiis tarsisque fusco-testaceis. Long. 10. 



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. 



CHAETOCNEMA Stephens. 



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

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

 convexis fortius confuse punctato-striatis. Long. - 08. 



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. 



LUPERUS Geoffr. 



L. varipes, elongatus, supra cyaneo-viridis, haud politus, thorace quadrato, latitudine haud 

 breviore, angulis rectis, lateribus antice paulo rotundatis sat dense punctato ; elytris punctatis ; 

 subtus niger, pedibus anticis testaceis, tarsis et femorum dimidio basali nigro-fuscis, antennis 

 fuscis ad basin fusco-testaceis. Long. 19. 



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 quadrato, latitudine 

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

 elytris virescentibus, subtiliter scabro-rugosis, versus latera obsolete striatis ; pedibis anten- 

 nisque nigris, his articulo secundo subpicescente. Long. 2. 



One specimen, Oregon. Also very distinct from any other North American species known 

 to me. 



GALLERUCA Geoffrey. 



G. rudis, picea, ovata, convexa supra glabra, capite thoraceque rude punctatis, hoc late 

 canaliculate, bifoveato, inaequali, antrorsum angustato, lateribus subangulatis ; elytris sutura 

 elevata costisque quatuor sublaevibus, interstitiis sulcoque marginali profunde rude punctatis. 

 Long. *4.
