Ancylochira a d i e c t a, supra splendide viridiaenea, dense punctata, crassius- 

 cula, thorace latitudine fere triplo breviore, antrorsum anguslato, lateribus late 

 rotundatis cuprascentibus, late canaliculate-, elytris lateribus late, sutura an- 

 guste cupreis, costis utrinque 4, scutellarique cum sutura confluente elevatis 

 laevibus nitidis, costa altera subsuturali fere integra adiecta, interstitiis dense 

 punctatis, apice subemarginata. Long. *6, lat '25. 



One specimen found between Fort Vancouver and Yokolt Plain, in July. This 

 species belongs to a group of species having the form of A. aurulenta and striata, 

 but differs from all the others known to me by having obsolete costae in the in- 

 tervals between the four ordinary costae, and by having an additional costa ex- 

 tending nearly from the apex to the base between the elevated suture and the 

 normal first dorsal costa. The head is entirely free from hair, and is uniformly 

 punctured ; the under surface of the body is bright coppery, tinged with green, 

 moderately punctured; the prosternum is broadly impressed between the coxae, 

 and is not hairy. 



Ancylochira lauta, supra splendide viridi-aurea, dense punctata, fronte non 

 concava fere glabra, thorace latitudine plus duplo breviore, antrorsum angustato, 

 lateribus late rotundatis cuprascentibus, late canaliculato, elytris lateribus late, 

 sutura anguste cupreis, costis 4, alteraque scutellari cum sutura confluente nitidis 

 laevibus elevatis, interstitiis dense granulato-punctatis, apice vix truncata.

Abundant in Oregon, whence it has been brought by Dr. Townsend, Capt. 

 Wilkes' Expedition, Col. M/Call and Dr. Cooper. Resembles the brilliant 

 variety of A. striata, but is distinguished by its more robust form, and by the 

 costae of the elytra being impunctured. A variety occurs in which the elytra have 

 each a broad blue vitta, extending from the first to the third costa. The body be- 

 neath is coppery, somewhat hairy, and the antepectus is impressed between the 

 coxae ; the front has a narrow somewhat smooth medial line. 



Ancylochira radians, supra splendide'viridi-aurea, dense punctata fronte 

 concava, longe albo-pilosa, thorace latitudine vix duplo breviore, antrorsum an- 

 gustato, lateribus late subrotundatis cuprascentibus, disco late canaliculato, 

 elytris sutura margineque cupreis, costisque quatuor alteraque scutellari cum 

 sutura confluente nitidis elevatis laevibus, interstitiis dense granulato-punctatis, 

 apice subtruncata. Long. *6, lat. -23. 



One specimen found at Fort Vancouver. It is with some hesitation that I 

 venture to describe this species as distinct : its general form is narrower than A. 

 lauta, and is very much that of A. striata: from the latter it differs by the 

 somewhat concave and pilose front. The pectus is as in the other species, but 

 is densely clothed with long white hair. The under surface is coppery golden, 

 more densely punctured than in the preceding. 



Ancylochira pl'acida, viridi-aurea, cupreo-tincta, confertissime punctata, 

 thorace latitudine fere duplo breviore, antrorsum subangustato, lateribus late ro- 

 tundatis, postice transversim impresso, elytris vitta cuprea utrinque ornatis, 

 striis punctatis haud distincte impressis, apice conjunctim rotundatis, Long. 29. 



Collected by the late J. K. Townsend, in Oregon, and given me by Mr. Will- 

 cox, as Phcenops placida of the Berlin museum. The form of body is more 

 cylindrical than in the other species known to me; the pectus is not canaliculate, 

 and the prolongation of the sternum is broader and more obtuse than in A. 

 decora, or the other species with which I have compared it. The insect, though 

 differing from Ancylochira in having the scutel slightly pointed behind, ap- 

 proaches much nearer to that genus than to Phaenops, and until a revision is made 

 of the genera of our native Buprestidae on more natural characters than have 

 been hitherto employed in their study, should be suffered to remain where I 

 have placed it. 



Ellycbnia facula, elongato-elliptica, atra tenuiter pubescens, thorace latitu- 

 dine vix breviore, disco convexiusculo, lateribus et apice concavis reflexis 

 punctatis, macula submarginali lunata rosea ornato, elytris dense punctulatis 

 linea unica dorsali obsoleta utrinque notata. Long. *52. 



One specimen, Prairie Paso, differs from E. corrusca by its less dilated
