STUDIES IN THE AMERICAN BUPRESTID^E 169 



between the acute apices twice as wide as deep. Length 1 2.6-14.0 

 mm.; width 4.7-5.2 mm. Wisconsin (Bayfield), — H. F. Wickham. 



cupripes n. sp. 



Body larger and stouter, moderately convex, much inflated posteriorly, dull 

 cupreous and black above, with the apices a little more cupreous, the 

 under surface obscure purplish-bronze, the legs cupreous, the tarsi sub- 

 cupreous with strong blue-green metallic lustre which is fainter basally; 

 head very small, densely, rugosely punctate, with a moderate and rather 

 indefinite anterior concavity, the callous basal median parts low and 

 only extremely finely striate along the middle; antennae bluish-bronze; 

 prothorax much more than twice as wide as the head, fully twice as 

 wide as long, widest scarcely behind the middle, the sides rounded, 

 gradually strongly converging anteriorly, the apex bisinuate, the angles 

 anteriorly prominent; surface coarsely and unevenly punctato-rugose, 

 strongly impressed just behind the middle near each side, the poUshed 

 median line entire; scutellum cupreous, strongly trapezoidal as usual, 

 impressed medially; elytra wider than the prothorax, the sides pos- 

 teriorly rapidly converging from the rounded post-median inflation, 

 becoming only very feebly sinuate for a short distance before the apices, 

 which are barely at all prolonged, the tips narrowly truncate and with 

 rounded external angles; surface strongly, very irregularly punctate, 

 with rather fine striae, the intervals feebly convex, with oblong polished 

 black spots which are much confused as a rule; under surface (9) 

 rugose laterally and smooth and sparsely punctured medially as usual, 

 the presternum convex and almost impunctate between the sulci, the 

 fifth ventral with a small deep rounded notch. Length 16.0 mm.; 

 width 5.9-6.2 mm. New Mexico parviceps n. sp. 



4 — Form oblong, stouter than in the preceding species, dark bronzy-cu- 

 preous above, the posterior extremity without the faintest tendency to 

 become cupreous, the under surface and legs brighter bronze, the tarsi 

 very dark metallic green-blue to indigo-black; head less coarsely and 

 more evenly, densely punctato-rugulose, broadly concave anteriorly, 

 the median callous part at base with a strong though fine stria; anten- 

 nae blue-blackish; prothorax two-thirds wider than long, the sides 

 obtusely subangulate at or just behind the middle, parallel thence 

 to the base and strongly converging and straighter to the apex, 

 which is broadly sinuate; surface coarsely, densely and more evenly 

 punctate, with a broad and uneven sublateral callous vitta and a very 

 irregular callous area medially near each side, the median smooth line 

 distinct, entire; scutellum trapezoidal, metallic, impressed medially; 

 elytra scarcely twice as long as wide, sHghtly inflated post-medially, 

 the sides there rounding, becoming oblique, then feebly sinuate to the 

 apices, which are not evidently prolonged, the tips rather broad, sinuato- 

 truncate, with rather acute angles; surface with the striae fine and closely, 

 finely punctate, scarcely impressed, the intervals flat, closely punctate, 

 coarsely and transversely, subconfluently so laterally, the black cal- 

 lous spots numerous but small and very irregular; under surface ( $) 

 rugose laterally, broadly smooth medially, the presternum very broad.
