A. radians, sujira splendide viridiaiirea, dense punctata, fronte concavo longe albo-piloso, 
thorace latitudine vix duplo breviore, antrorsum angustato, lateribiis late subrotundatis cupra- 
scentibus, disco late canaliculate, elytris sutura margineque cupreis, costis quatuor scutellarique 
cum sutura elevata confluente nitidis laevibus, interstitiis dense granulate punctatis, ad apicem 
subtruncatis. Long. . .

One specimen, Fort Vancouver, Dr. Cooper. Perhaps, not distinct from A. lauta, but the 
body is narrower, being of the form of A. striata; from the latter it differs by the concave and 
pilose front ; the pectus is as in the preceding, but is densely clothed with long white hair ; the 
under surface is coppery golden, more densely punctured than in A. lauta. 
BuPRESTis Linn. 
B. anguUcollis , aenea, depressa, capite excavato, canaliculato, grosse cicatricoso, tliorace 
latitudine breviore, lateribus postice parallelis, ante medium angulatis, inaequali, versus 
angulos posticos late excavato, punctato, partibus elevatis costaque dorsali lata elevatis nitidis, 
elytris sutura, costisque solitis elevatis, secunda late tridilatata, et callo basali instructa, 
quarta breviore tenui postice late dilatata, partibus elevatis laevigatis nitidis, impressionibus 
punctatissimis, lateribus baud serratis. Long. 1.13. 
Sacramento, Mr. Wittick. Larger than B. virginica, in which also the sides of the thorax 
are sometimes angulated, but never to such an extent as in this species ; the dilatations of the 
second and third elevated lines of the elytra are much wider. 
Melanophila Esch. 
M. conspicta, elongata depressa, atra opaca, capite rugose punctato, thorace tenuiter canalicu- 
lato, disco subtiliter transversim rugoso, lateribus punctato et lineis elevatis aciculato, angulis 
posticis longius carinatis, elytris postice oblique angustatis confertim granulato-punctatis, guttis 
utrinque quatuor obscure croceis ornatis ; subtus aeneo-nigra. — Long. '47. 
Northern California, Mr. Child. This species has nearly the form of our common 31. longipes, 
but is a little narrower ; the tips of the elytra are separately rounded and not at all acuminate. 
The spots on each elytron are arranged ; one a little before the middle, one-third from the 
suture ; another just behind the middle, one-third from the margin; then, two on a transverse 
line, one-third from the apex ; they, therefore, form, with those of the opposite side, a figure 
rounded anteriorly, with a straight posterior outline. 
Anthaxia Esch, 
A. expansa, lata depressa, atra^ opaca vix aenescens, thorace latitudine duplo breviore, 
lateribus, valde rotundatis depressis, reticulatim punctato, elytris thorace baud latioribus, con- 
fertim granulato-punctatis, fortius marginatis, postice suboblique attenuatis ad apicem rotun- 
datis, ad basin elevato-marginatis. — Long. '28. 
Oregon and California. Kesembles a species found in New Mexico, which I consider as 
A. aeneogaster Lap., but is still broader, with the sides of the thorax more rounded, and the 
posterior angles more obtuse. The base is not truncate as in most Anthaxiae, but is slightly 
obtuse at the middle ; this character, with the sculpture of the thorax and elytra, indicates a 
passage towards Melanophila.
