San Jose, California. Larger than 0. colon , and distinguished by distinctly channelled and 
less convex thorax, by the greater number of the dark spots of the elytra being behind the 
middle, while in 0. colon the reverse is the case. 
Meligethes Steph. 
M. rufimanus, ovalis, virescenti niger subnitidus, dense subtilius punctatus, breviter cinereo- 
pubescens, thorace lateribus antice rotundatis, angulis posticis obtusis tibiis anticis rufis paulo 
dilatatis extrorsum serrulatis, posterioribus dilatatis dense spinulosis. Long. *09—‘10. 
San Jose, California, on the flowers of Ranunculus. The thorax is nearly twice as wide as 
long; the sides are almost parallel behind the middle, hut converge anteriorly, and are con¬ 
siderably rounded ; the elytra are broadly rounded at tip, and are one-half longer than their 
width. 
M. moerens, ovalis, nigro-virescens, subnitidus dense subtilius punctatus, tenuiter griseo- 
pubescens, thorace lateribus rotundatis angulis posticis obtusis, tibiis anticis minus dilatatis, 
ad basin subtilissime, ad apicem distinctius crenulatis, posterioribus dilatatis extrorsum dense 
spinulosis. Long. - 10. 
Oregon. Very similar to M. rufimanus , but differs in the sides of the thorax being more 
rounded, with the posterior angles more obtuse; the anterior tibiaa are narrower, and the 
crenulation towards the base becomes so fine as to be hardly visible. 
M. seminulum, ovalis convexior, niger nitidus, thorace sat dense subtilius punctato, tenuiter 
marginato, latitudine plus duplo breviore, lateribus rotundatis, angulis posticis obtusis, elytri 
subtilius sat dense punctatis, tibiis omnibus modice dilatatis, anticis versus apicem subtiliter 
crenulatis posterioribus extrorsum spinulosis. Long. -08. 
Oregon, one specimen. The pubescence has probably been removed by the alcohol in which 
the specimen was preserved. Smaller and more convex than the others, and the margin of 
the thorax is narrower; the thorax itself is wider and more rounded on the sides. The 
anterior tibiae at the base appears smooth. 
Amphicyrta Er. 
A. chrysomelina, aptera, longius ovata, antice angustior piceoaenea, nitida convexa, dense 
subtiliter punctulata, tarsis piceis, tibiis anticis extrorsum obtuse angulatis. Long. '35.

Cremastochilus Enoch. 
G. angularis, ater opacus, breviter setosus, thorace confertim punctato, lateribus antice rotun¬ 
datis, postice obliquis, angulis anticis foveatis acutis, posticis productis elevatis acutis, impres- 
sione obliqua definitis, elytris punctis minus profundis ellipticis ; mento concavo postice acumi- 
nato. Long. '5.
