Elytral apices entire, not sinuate or bidenticulate 3 



3 — Body elongate, parallel, but feebly inflated posteriorly, not very convex, 

 obscure bronze, the apex but feebly cuprascent-red ; under surface 

 brighter bronzy-cupreous, the legs bronze, with the tarsi green-blue; 

 head coarsely, confusedly punctato-rugose, broadly concave anteriorly, 

 the median line basally elevated and with a fine median stria ; antennae 

 deep greenish-blue; prothorax nearly twice as wide as long, widest 

 behind the middle, the sides evenly rounded, becoming gradually very 

 convergent and straighter anteriorly, the apex broadly, subevenly 

 sinuate; surface coarsely, closely punctate, with very large irregular 

 callous spots scattered throughout, the median smooth line slightly 

 elevated and entire; elytra evidently wider than the prothorax and 

 five times as long, more than twice as long as wide, the sides very grad- 

 ually rounding and then rather rapidly converging in posterior two- 

 fifths, becoming sinuate before the slightly prolonged and divaricate 

 apices, the tips very much and rapidly narrowed from within by the 

 separating notch and narrowly truncate; surface punctato-striate, 

 the striae obsolete laterally, the intervals punctate and with small irregu- 

 lar smooth black and very feebly elevated spots; under surface (9) 

 densely, rugoseiy punctate laterally, smooth and sparsely but strongly 

 punctate medially, the prosternum convex between the lateral sulci, 

 the fifth ventral with a small, evenly rounded sinus which is twice as 

 wide as deep. Length 14.5 mm.; width 5.0 mm. Colorado; Mis- 

 souri Valley, — Say. [=Buprestls cyanipes Say] cyanipes Say 



Body much less elongate, moderately convex, more blackish, with the 

 smaller depressed areas gray-bronze above, the posterior extremity but 

 faintly cuprascent and very near the tips only; under surface more 

 shining, cupreous, the legs and tarsi bright bronze, the latter with a 

 very faint greenish lustre except basally; head densely, rugosely punc- 

 tate, with a large and deep rounded anterior depression, the median 

 parts thence to the base strongly, broadly elevated, smooth and with 

 a very coarse impressed median stria; antennae obscure bronze; pro- 

 thorax parallel, widest at the middle, the sides evenly and rather 

 strongly arcuate, equally converging apically and basally, the apex 

 feebly, subevenly sinuate; surface rather uneven, more or less impressed 

 posteriorly near the sides, very coarsely, densely punctate and rugose, 

 the median polished line sharply defined and entire; scutellum shorter, 

 more transverse and less narrowed basally than usual, dull blackish; 

 elytra obviously wider than the prothorax, but feebly inflated posteriorly, 

 twice as long as wide, the sides gradually rounding and converging poste- 

 riorly, becoming only feebly sinuate near the apices, which are scarcely at 

 all prolonged and but little narrowed by the very small separating 

 notch, the tips rather broad and truncate; surface much more rugose 

 than usual, the strial intervals more convex and prominent, the black 

 polished elevated spots much more extensive than the small and de- 

 pressed bronze spots, which are rather coarsely punctate; under sur- 

 face ( cf ) rugulose laterally, the median parts pubescent, the prosternum 

 broad, rather closely punctate throughout and flat, the metasternum 

 impressed along the middle, the fifth ventral with a large abrupt sinus
