Oregon, Dr. Cooper, at Shoalwater Bay; Steilacoom, Mr. Gibbs. Of this species I have seen 

 three specimens ; one is bright copper colored ; the second is green, with the elytra immaculate ; 

 the third is bright green with an oblique yellow lobate spot behind the middle of each elytron ; 

 the apex in one is truncate, in the others slightly bidentate. 



A. laeviventris, nigro-aenea, subtus nitidior, abdomine vis obsolete punctato, lateribus parce 

 albo-pilosis, segmento ultimo macula utrinque transversa sanguinea notato ; thorace latitudine 

 hand breviore, antrorsum angustato, lateribus rectis, angulis omnibus subacutis, disco sat grosse 

 punctato, linea longitudinali plagisque utrinque duabus sublaevibus ; elytris minus nitidis, 

 sulcato, striatis, macula trilobata utrinque prope basin ultra medium extensa, alteraque ad 

 dodrantem transversa fulvis ornatis. Long. 'YS. 



Northern California, Mr. Child. Allied to A. Nuttalli, but is narrower ; the thorax is longer 

 and the punctures of the abdomen are very indistinct. The anterior spot extends from near 

 the base for two-thirds the length of the elytra, and is composed of three confluent spots, each 

 of which is sub-triangular. Specimens will probably occur in which these spots are not united. 



A. adjecta, supra splendide viridiaenea, dense punctata, crassiuscula, thorace latitudine fere 

 triplo breviore, antrorsum angustato, lateribus late rotundatis cuprascentibus, late canaliculato, 

 elytris sutura anguste, margine late cupreis, costis utrinque quatuor scutellarique cum sutura 

 elevata confluente laevibus nitidis, costa altera subsuturali fere integra adjecta, interstitiis dense 

 punctatis, ad apicem subemarginatis. Long. '6.

One specimen found by Dr. Cooper, on the journey from Fort Vancouver to Yokolt Plain, in 

 July. This species is allied to the two next, as well as to A. auridenta and striata, but differs 

 from them all by having obsolete costae between the ordinary ones, and by having an addi- 

 tional costa extending nearly from base to apex between the first dorsal and the suture. The 

 head is glabrous, and uniformly punctured ; the under surface is bright coppery, tinged with 

 green, moderately punctured ; the presternum is broadly impressed between the coxae, and is 

 not hairy. 



A. lauta, supra splendide viridiaurea, dense j^unctata, fronte fere glabro non concavo, thorace 

 latitudine plus duplo breviore, antrorsum angustato, lateribus late rotundatis cuprascentibus, 

 late canaliculato, elytris sutura anguste margine late cupreis, costis quatuor alteraque scutel- 

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

 apicem vix truncatis. Long. '58 — "TS.

Abundant in Oregon, whence it has been brought in every collection made. Eesembles the 

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

 tured costae of the elytra ; varieties occur, having a broad blue vitta extending from the first to 

 the third costa. The body beneath is coppery, somewhat hairy, and the prosternum is impressed 

 between the coxae ; the front is marked with a very narrow nearly smooth medial line.
