A. radians, supra splendide viridiaurea, dense punctata, fronte concavo longe albo-piloso, 

 thorace latitudine vix duplo breviore, antrorsum angustato, lateribus late subrotundatis cupra- 

 scentibus, disco late canaliculate, elytris sutura margineque cupreis, costis quatuor scutellarique 

 cum sutura elevata confluente nitidis laevibus, interstitiis dense granulato punctatis, ad apicem 

 subtruncatis. Long. •6. 



Lee. Proc. Acad. Nat. Sc, 7, 1*7. 



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 Avhite hair ; the 

 under surface is coppery golden, more densely punctured than in A. la^da. 



BuPEESTis Linn. 



B. angulicoUis, aenea, depressa, capite excavato, canaliculato, grosse cicatricoso, thorace 

 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. 



MELAIfOPHILA Esch. 



M. consjnita, 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 angustatisconfertim granulato-j)unctati8, guttis 

 utrinque quatuor obscure croceis ornatis ; subtus aeneo-nigra. — Long. '47. 



Northern California, Mr. Child. This species has nearly the form of our common if. 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 i^osterior outline. 



Anthaxia Esch, 



A. expansa, lata depressa, atra, opaca vix aenescens, thorace latitudine duplo breviore, 

 lateribus, valde rotundatis depressis, reticulatim punctato, elytris thorace hand latioribus, con- 

 fertim granulato-punctatis, fortius marginatis, postice suboblique attenuatis ad apicem rotun- 

 datis, ad basin elevato-marginatis. — Long. "28. 



Oregon and California. Eesembles 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 truucate 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.
