REVISION OF THE BUPRESTIDA OF THE UNITED STATES. 221 
A specimen found in Philadelphia, was kindly given me by Mr. George Newman. 
Smaller than the others. Head coarsely punctured, front not concave; thorax more than 
twice as wide as long, strongly angulated on the sides, narrowed to the base, but more nar- 
rowed to the apex; coarsely and equally punctured, disc flattened towards the middle, 
with a large oblong fovea at the middle of the base. Elytra parallel on the sides, obtusely 
rounded and serrate at the tip; striate with rows of square punctures, the interstices fine- 
ly sparsely punctured, the 3d growing gradually wider and more elevated towards the 
base. The subsutural row of punctures forks near the base, leaving a short interval. 
5. P. velasco, nigro-znea, fronte plana, thorace planiusculo, postice subfoveato, et subtiliter canaliculato, 
disco antice utrinque late impresso, elytris seriatim grosse punctatis, interstitiis parce punctatis, alternatim elati- 
oribus. Long. -77. 
Laporte & Gory, Mon. Buprest, 2, 6, tab. 1, fig. 7. 
A Mexican species, but found by Mr. Arthur Sshott on the Rio Grande in Texas. 
Body black bronzed. Head coarsely punctured, front flat, with a slight medial elevated 
line. Thorax nearly three times as wide as long, obtusely rounded on the sides at the 
middle, narrowed to the base, but more so to the apex, coarsely punctured, densely at the 
sides, not densely at the middle, slightly broadly impressed at the middle of the base, and 
with two faint rounded impressions before the middle: a fine impressed dorsal line ex- 
tends from the middle to the base. Elytra slightly narrowed from the base to three- 
fourths of the length, then obliquely narrowed to the apex, which is rounded; with strix 
of large punctures, the interstices finely punctured, alternately a little more elevated, sutu- 
ral costa bifurcated a little before the middle, thus forming a long and broad scutellar costa.

1. P.luctuosa Gory Mon. Buprest. 4, 71, tab. 15, f. 69. 
Buprestis gibbicollis || Say, Journ. Acad. Nat. Se. Phil. 3, 161. 
Alabama, Ohio, Missouri: Say stated (Trans. Am. Phil. Soc. 6, 158) that the name 
given by him was preoccupied for a Huropean species, and ought to be changed, but neg- 
lected to propose another. I am, therefore, under the necessity of adopting the more 
recent name of Gory. Erichson, by a singular error, mentions this species (Bericht, &c., 
1840, 19) as belonging to Acmeodera. 
AcmopDERA Esch. 
Though but few species of this genus are found within the old limits of the United 
States, the extension of our territory towards the South and West, has introduced into 
our fauna a considerable number, of which several extend into Mexico, and were pre- 
viously described from that country; probably others of the species described by me, may
