STUDIES IN THE AMERICAN BUPRESTID^ IO9 



38 — Sides of the prothorax evenly arcuate from base to apex. Body very 

 elongate, moderately convex, shining, viridescent, with very strong 

 cupreous lustre, the under surface brilliant cupreous-red medially and 

 throughout the abdomen, viridescent laterally and with unusually long 

 ashy pubescence; head very densely and confluently but subuni- 

 formly punctate, the eyes large and prominent; prothorax three-fifths 

 wider than long, the apex decidedly narrower than the base, obsoletely 

 bisinuately truncate; surface strongly, closely punctate, densely and 

 more coarsely so laterally, with the impression large, shallow and dif- 

 fuse, the median line broadly but strongly impressed throughout; 

 elytra between four and five times as long as the prothorax and a fourth 

 wider, parallel, the sides rounding and converging behind in apical 

 third, the apices sinuate and acutely bidentate; sculpture as in histri- 

 notata but with the punctures of the inner of the two confused series of 

 the striae more distinct; anterior pale luteous spot large, longer than 

 vAde and anteriorly pointed, the second large, almost rounded, the 

 third broad, attaining neither suture nor sides; abdomen with the basal 

 segment feebly flattened medially, the punctures fine but strong, 

 dense laterally, the fifth segment broadly, angularly emarginate at 

 tip in the male. Length 16.0 mm.; width 5.2 mm. Oregon (New- 

 port), — H. F. Wickham callida n. sp. 



Sides of the prothorax gradually more arcuate basally. Body less elongate, 

 parallel, subdepressed, shining, green, sometimes with very evident 

 cupreous lustre, cupreous beneath on the abdomen, otherwise green 

 laterally; head densely, confluently punctate, the eyes prominent, 

 pale in examples at hand; prothorax shorter, three-fourths wider than 

 long, the apex much narrower than the base ; surface broadly impressed 

 medially, strongly, rather closely punctate, subconfluently so laterally, 

 without evident impression; base with a small truncate and abruptly 

 formed lobe at the scutellum, which is not at all evident in callida, the 

 ante-scutellar puncture distinct; scutellum small, rounded, variable; 

 elytra as in callida though shorter, but little more than twice as long as 

 wide, the sides more arcuate to the tips, which are sinuate and bispicu- 

 lose as usual; sculpture and maculation nearly similar, as is also the 

 punctuation of the under surface, the anterior spot much smaller, 

 the post-median more transverse; apex of the fifth ventral transversely 

 truncate in the male. Length 14. 5-15. 5 mm.; width 5.0-5.6 mm. 

 California fastidiosa n. sp. 



A — General characters relating to form, coloration, maculation and 

 sculpture as in fastidiosa, the eyes still more prominent; prothorax 

 notably shorter and more evidently narrower than the elytra, almost 

 twice as wide as long and rather more sinuate at apex, but otherwise 

 similar; elytra even more rounded on the converging sides in apical 

 third, the sinus of the apices very much narrower than in any other 

 form of this group; abdomen much less cupreous and only faintly 

 so medially, broadly green laterally. Length 13.0 mm., width 4.6 

 mm. California mediocris n. subsp. 



39 — Elytral apices more broadly and frequently obliquely sinuato-truncate
