STUDIES IN THE AMERICAN BUPRESTID^ IO3 



Pronotum with a deep foveiform impression at each side of the median line 

 before the middle but otherwise not distinctly impressed. Surface 

 shining, greenish-black; head (6^) coarsely, densely punctate and par- 

 tially impunctate, the entire space between the eyes yellow-orange, 

 except a large median anteriorly and deeply incised black spot; eyes 

 large but not prominent; antennae slender; prothorax short, almost 

 twice as wide as long, only moderately narrowed anteriorly, the sides 

 subevenly rounded, a Uttle more so basally , widest at about basal 

 third; surface strongly, sparsely punctate, densely so laterally, the sub- 

 lateral smooth spots coalescent, not prominent, with traces of the 

 subbasal depressions of the preceding; anterior sides and lateral third 

 of the apical margin pale; elytra nearly as in nigricans but only very 

 slightly wider than the prothorax, the apices subtruncate and with 

 feeble minute irregularities but with the outer angle obtusely rounded ; 

 surface strongly but not closely punctate, the intervals alternatingly 

 rather wide, moderately convex, less polished and feebly rugose and 

 narrower, strongly convex, smooth, less punctate and very lustrous, 

 the arrangement very regular throughout the width; abdomen deeply 

 sulcate basally, strongly, rather closely punctate, the third and fourth 

 segments each with a very small red dot laterally, the fifth with two large 

 transverse red spots, the apex evenly and distinctly sinuate with simple 

 angles. Length (c?) 18.5 mm.; width 6.9 mm. British Columbia 

 (Golden) lyrata n. sp. 



Pronotum without evident impressions. Body large and elongate, shining, 

 black or greenish-black to faintly violaceous in lustre; head nearly as in 

 lyrata, sometimes with a larger finely and densely punctate medial area, 

 the pale area surrounding the interocular surface nearly similar and 

 frequently as well developed in the female as in the male; prothorax 

 larger, much less transverse, generally but little narrower at base than 

 at basal third, the sides more even thence to the apex, nearly straight 

 or feebly arcuate, sometimes feebly biarcuate, but, in the male, some- 

 times subangularly prominent behind basal third; surface more densely 

 punctate, with the sublateral smooth areas usually large though not 

 prominent; elytra but little wider than the prothorax, generally fully 

 twice as long as wide, the apices truncate to arcuato-truncate, nearly 

 even, the sutural angle unusually evident for this section; surface nearly 

 as in lyrata but less strongly punctate, the wider intervals more nearly 

 flat and not so rugulose, the narrower less convex; abdomen strongly 

 but not very coarsely, closely punctate, sulcate at base, the fifth seg- 

 ment with a large and generally entire transverse red fascia, the two 

 or three preceding also sometimes with a small red dot at each side, 

 the fifth broadly sinuate at tip (d*), or arcuato-truncate with obtuse 

 angles (9); females abundant, the male rare. Length (c?) 15.0, (?) 

 18.0-23.0 mm.; width (c?) 5.8, (?) 7.0-8.8 mm.; dimensions of one 

 9 23.0 by 8.3 mm., of another 9 22.0 by 8.8 mm.. Oregon, Idaho
