very evident except laterally, coarsely punctured suturally, the areolae 

 not well defined; under surface coarsely rugose, smoother and chan- 

 neled axially as usual, the apex of the fifth ventral ( 9 ) with the sinus 

 small, the lateral lobes very broad and the median tooth broadly tri- 

 angular. Length ($) 20.0 mm.; width 6.7 mm. Vancouver Island 

 (Victoria) vancouveri n. sp. 



Body rather small in size and less stout, moderately convex, shining, ob- 

 scure brassy-bronze in color, brighter beneath; head densely, moder- 

 ately coarsely and subevenly punctato-rugose, with a central depression 

 before a small transverse callus; eyes rather small and not very prom- 

 inent; prothorax fully four- fifths wider than long, the sides broadly, 

 subevenly arcuate and converging from slightly behind the middle to 

 the apex, parallel and sinuate in but little more than basal third; sur- 

 face not or scarcely impressed medially, except narrowly so anteriorly, 

 the basal pit triangular and deep, densely, coarsely and confusedly 

 punctate laterally, with a few callous spots; elytra but slightly wider 

 than the prothorax, parallel, gradually and broadly rounding and con- 

 verging in apical two-fifths, the prolongation gradually formed, atten- 

 uate and rather long; surface with rather coarse striae which are visible 

 almost throughout, the striae only feebly impressed but coarsely and 

 unusually distinctly punctured, thfe sculpture coarse, dense and con- 

 fused laterally, the callous spots almost wanting before, moderately 

 conspicuous behind, the middle, the areolae not defined; under surface 

 rugose and axially sulcate, the last ventral ( J*) with the deep emargi- 

 nation transversely rectilinear at the bottom, the lobe occupying the 

 entire width. Length (c^) 15.5 mm.; width 5.0 mm. Wisconsin.

19 — Pronotum not impressed along the median line except anteriorly 20 



Pronotum more or less deeply sulcate throughout along the middle 21 



20 — Form rather narrow, elongate and parallel, moderately convex, shining, 

 obscure gray- metallic in lustre, scarcely bronzed beneath; head coarsely, 

 confusedly compresso-punctate, feebly but unequally impressed along 

 the middle, the eyes well developed and prominent; prothorax nearly 

 twice as wide as long, the sides prominent, almost obtusely angulate at 

 the middle, where the width is but slightly greater than at base, thence 

 gradually converging and feebly arcuate to the apex, broadly sinuate 

 basally; surface obliquely impressed sublaterally behind the middle, 

 coarsely, confusedly punctato-rugose laterally, with a definite callous 

 spot only before and behind the impression; elytra nearly two and one- 

 half times as long as vnde, barely wider than the prothorax, the sides 

 very gradually rounding and converging in apical two-fifths, becoming 

 gradually and broadly sinuate, the prolongation long, somewhat atten- 

 uate and cuprascent, the surface unevenly sulcate, the elevations only 

 moderate in number and prominence, the foveote rather small and 

 definite posteriorly but not more finely punctate; under surface rugose 

 and deeply sulcate axially, the last ventral ( 9 ) with the apical sinus 

 but little wider than deep, the tooth gradually and very finely aciculate.
