STUDIES IN THE AMERICAN BUPRESTID^ II9 



posteriorly than in brevis but scarcely at all entering the metasternum; 

 first ventral strongly convex medially; legs short, slender, the first joint 

 of the hind tarsi rather longer than the next two. Length 18.5 mm.; 

 width 7.2 mm. New Mexico intricata n. sp. 



5 — Third of the true elytral costae very short 6 



Third costa long, extending to between apical third and sixth 7 



6 — Form strongly depressed, the pronotum feebly impressed along the mid- 

 dle. Body oblong, gradually attenuate posteriorly, above obscure and 

 dark in color, the head and sides of the upper surface more or less 

 cupreous, the bottoms of the elytral rugosities bluish-metallic; beneath 

 not very shining, densely sculptured and cupreous; head finely, very 

 densely punctured, with long and conspicuous pubescence, the eyes 

 rather prominent; antennae nigro-metallescent; prothorax four- fifths 

 wider than long, the sides rather strongly convergent and nearly straight, 

 becoming arcuate and more strongly convergent only near the apex; 

 base broadly and feebly arcuate, faintly sinuate laterally; surface con- 

 vex, with moderate metallic punctures which are coalescent in small 

 groups, dense laterally and also dense but smaller in the faint median 

 depression; scutellum oblong, concave, cupreous; elytra nearly twice 

 as long as wide, slightly wider than the prothorax, the parallel sides 

 becoming gradually broadly rounded behind three-fifths, and thence 

 feebly convergent and nearly straight to the rather narrow apices, 

 which are rounded externally and not at all sinuate, the sutural angles 

 right, not prolonged ; surface notably depressed, with the usual convex 

 costae strong, the third abbreviated a little behind the middle, the sub- 

 lateral very much elevated and conspicuous, the intermediate surfaces 

 coarsely, confusedly reticulato-rugose; under surface rather finely but 

 densely punctate and conspicuously pubescent throughout, the pro- 

 sternum broadly concave and densely sculptured and hairy, the first 

 ventral convex medially. Length (c?) 13.4 mm.; width 5.3 mm. 

 Lake Superior (Whitefish Point) lateralis n. sp. 



Form convex, the pronotum deeply canaliculate. Body rather broad, 

 above obscure brassy-green; prothorax coarsely and densely punctate, 

 narrowed anteriorly, the sides at the middle almost angulate, posteriorly 

 sinuate; elytra densely and rugosely punctate, the suture, a scutellar 

 costule, the margins and four discal costae on each strongly elevated 

 and smooth, the third discal costa greatly abbreviated; apices some- 

 what prolonged, truncate; under surface brassy-green. Length 15.5 

 mm. Lake Superior sulcicollis Lee . 



7 — Under surface of the body duller cupreous, obscure or blackish toward 

 the median line. Body large, oblong, moderately convex, the head and 

 pronotum bright cupreous, the latter suflfused with greenish on the 

 central parts; elytra deep vivid green, the sutural ridges and the lateral 

 margins, including the fourth costa, bright cupreous; head rather 

 pubescent, coarsely, deeply punctate, the punctures longitudinally con- 

 fluent and compressed, a small central region depressed and finely, 

 densely punctured and more greenish; eyes not prominent; antennae
