San Jose and San Diego. Similar in form and sculpture to H. albionica ; the fifth joint of 
the antennje of the male is conical and dilated. 
PsYLLiODES Latr. 
P. parvicolUs, elongato-ovalis, antice angustior, aeneo-nigra, capite parce punctulato thorace 
confertim punctato, antrorsum angustato, angulis anticis oblique tnincatis ; elytris striato- 
punctatis, interstitiis paulo convexis punctulatis ; antennis fuscis ad basin tcstaceis, tibiis tar- 
sisque piceo-testaceis. Long. "09. 
San Jose, California. Of the same form as P. punctulata Mels., but with the strife of the 
elj'tra 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, 
tibiis tarsisque fusco-testaceis. Long. -lO. 
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 latitudine 
breviore, antrorsum baud 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.
