gradually formed and decidedly narrow; prothorax twice as wide as 

 long, prominently inflated and rounded at about the middle, the 

 sulcus evident but shallow, deeper anteriorly, the sublateral impres- 

 sions deep, the surface laterally very confusedly but subevenly puncta- 

 to- rugose ; elytra parallel, not wider than the prothorax, more elongate, 

 coarsely sulcate, the sulci coarsely punctate, obliterated only near the 

 sides, the elevations small and not conspicuous, the sublateral interval 

 posteriorly slightly more prominent and more or less broken as usual; 

 apical sinus ( 9 ) rather small, twice as vnde as deep, the tooth rather 

 long, slender and aciculate. Length (c?, 9) 19. 0-21. 2 mm.; width 

 6.2-6.8 mm. British America longipennis n. subsp. 



Color obscure bronze, a little more coppery beneath though dark; body 

 smaller, moderately convex, rather dull; head coarsely punctato-rugose, 

 impressed along the middle, the eyes moderate, rather prominent; 

 prothorax fully four-fifths wider than long, the sides evenly and broadly 

 rounded, strongly converging anteriorly, feebly so and slightly sinuate 

 basally; surface deeply sulcate, with a large deep basal pit, coarsely, 

 densely and confusedly but almost evenly punctato-rugose laterally, the 

 oblique impressions feeble but evident; elytra slightly wider than the 

 prothorax, very gradually rounding and converging at the sides in 

 apical two-fifths, the prolongation moderately wide, rather short and 

 gradually formed, the median notch large and deep; surface very con- 

 fusedly rugose throughout, the elevations numerous, small and irregu- 

 lar in form, the sulci only indicated by vague Unciform impressions, 

 which are coarsely punctate but only definitely so near the suture; pro- 

 sternum of the female with an unusually broadly concave rugose im- 

 pression, rapidly narrowing posteriorly, the metasternum broadly con- 

 cave, the first ventral impressed only anteriorly; medial tooth of the 

 apical sinus rapidly, very finely aciculate. Length (9) 16.0 mm.;

24 — Form stout, rather convex, not very shining, dusky cupreous, brighter 

 beneath; head coarsely, densely compresso-rugose, feebly impressed 

 along the middle, the eyes moderate, prominent; prothorax nearly 

 four-fifths wider than long, the sides prominently rounded rather be- 

 hind the middle, thence strongly converging and slightly arcuate to the 

 apex and feebly converging and very slightly sinuate to the base; sur- 

 face with a broad and shallow, densely sculptured channel inclosing a 

 small central callus and ending at base in a broad deep cavity, thence 

 to the sides coarsely, very densely punctate, with about three callous 

 spots, obliquely impressed behind the middle; elytra not evidently 

 wider than the prothorax, only slightly more than twice as long as wide, 

 gradually rounded and converging at the sides in apical two-fifths, the 

 prolongation gradually formed but rather broad and short, the cleft 

 narrow and deep; surface somewhat coarsely subsulcate almost through- 

 out the width, the sulci rather coarsely and irregularly, not distinctly 

 punctate, the elevations numerous and strong but for most part small 

 and irregular, the depressed spots brighter metallic, strongly punctate; 

 prosternum ( 9) as broadly concave and roughly sculptured as in the
