5 — Body more abbreviated and with the elytra more shining and more 

 metallic than in extensicollis, green anteriorly, green to bright aeneo- 

 cupreous on the elytra; under surface black, the legs testaceous; 

 head distinctly narrower than the prothorax, with large, moderately 

 prominent eyes; antennae very slender and filiform, fuscous, gradu- 

 ally pale basally, three-fifths as long as the body, the medial joints 

 nearly five times as long as wide; prothorax slightly shorter than 

 wide, the sides oblique and just visibly sinuate posteriad, finely 

 reflexed, but little more so basally; base scarcely as wide as the 

 deeply sinuate apex, the angles obtuse though usually with rather 

 sharply marked tips; surface smooth, punctulate at base, the stria 

 distinct, subentire; foveae large, deeply concave, usually not much 

 prolonged anteriorly, the bottom acutely linear; elytra one-half 

 longer than wide to less, a little less than twice as wide as the pro- 

 thorax, with more rapidly rounding humeri than in the preceding, 

 the sinus very shallow; striae moderately fine, deep, grooved and 

 without evident punctulation, sometimes more impressed toward the 

 humeri, the intervals usually not quite flat, the third with five small 

 punctures; anterior male tarsi distinctly though moderately dilated, 

 a little more so than in the preceding. Length (cf 9 ) 8.4-9.0 mm.; 

 width 3.0-3.6 mm. Nova Scotia to Pennsylvania. [An. thoraciciis 



Dej.; obscuratus Chd.; proximus Harris] elongatulus Dej. 



Body somewhat narrower and less convex, shining, the anterior parts 

 greenish or bluish metallic, the elytra obscure greenish to blackish, 

 moderately shining, less dull than in extensicollis; legs pale flavo- 

 testaceous; head distinctly narrower than the prothorax, rhom- 

 boidal, the eyes only moderate in size but prominent; anterior 

 impressions long, curving outwardly behind; antennae not so long 

 or finely filiform as in elongatulus, though slightly more than half 

 as long as the body, fuscous, paler basally, the medial joints not 

 over four times as long as wide; prothorax not quite as long as wide, 

 the oblique sides basally straight or just visibly sinuate, the margins 

 finely though abruptly reflexed; angles very obtuse though with 

 distinctly marked tips; apex deeply sinuate, with rather sharp and 

 prominent angles, fully as wide as the base, beaded as usual; stria 

 distinct, the anterior impression barely traceable; foveae deep, 

 lineate at the bottom, punctulate, prolonged anteriorly, sometimes 

 traceable beyond the middle; elytra oblong, fully one-half longer 

 than wide, nearly twice as wide as the prothorax; sides feebly 

 arcuate, the humeri rapidly rounding, the sinus feeble; surface 

 shining, duller in a specimen with black elytra; striae moderately 

 fine, deep and grooved, not evidently punctulate; intervals not 

 quite flat, the third with six punctures; anterior male tarsi feebly 

 dilated. Length (cf ) 8.5-9.2 mm.; width 3.2 mm. North Carolina

6 — Upper surface dark bluish or green, the elytra decidedly dull in 



lustre; legs pale testaceous 7 



Upper surface black or blackish, sometimes with very faint metallic 



tint as in texanus; legs frequently dark in color 8
