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., hut with the strife 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, 
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. 
Ciiaetocnema 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 cvanescentibus, 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 Geoffroy. 
G. rudis, picea, ovata, convexa supra glabra, capite thoraceque rude punctatis, hoc late 
canaliculato, bifoveato, inaequali, antrorsum angustato, lateribus subangulatis ; elytris sutura 
elevata costisque quatuor sublaevibus, interstitiis sulcoque marginali profunde rude punctatis. 
Long. *4.
