Il8 CASEY 



trapezoidal, with evenly and moderately arcuate sides, about twice as 

 wide as long, the surface very moderately impressed along the median 

 line, strongly, not densely punctate, coarsely and in part subconflu- 

 ently so laterally; base gradually prominent medially; elytra three- 

 fourths longer than wide, scarcely wider than the prothorax, the sutural 

 and next two ridges strong, separated by narrow sulci, the intermediate 

 ridges elsewhere low and smooth, the depressed Hues rugose; apices 

 narrowly sinuate and bidenticulate; under surface minutely, sparsely 

 punctate, the prosternum flat medially, entering the metasternum for 

 a considerable distance, the first ventral convex ; legs slender, the basal 

 joint of the hind tarsi equal in length to the next two. Length 13.8 

 mm.; width 5.8 mm. Vancouver Island ((Nanaimo), — H. F. Wick- 

 ham brevis n. sp. 



Elytral suture cupreous or subaeneous, as well as the side margins 4 



4 — Body rather stout, above bright brassy-green, densely punctured, the 

 under surface bright coppery tinged with green, moderately punctate, 

 the prosternum broadly impressed between the coxae and not hairy; 

 head uniformly punctured; prothorax "almost three times as wide as 

 long "(!), narrowed anteriorly, broadly rounded at the sides, cuprascent, 

 broadly canaliculate; elytra at the sides broadly, at the suture narrowly, 

 cupreous, each with four discal costae and one, scutellar, united with 

 the sutural, all smooth and shining, also with another costa, almost 

 entire, between the elevated suture and the normal first discal costa; 

 interstitial concave lines densely punctate, the apices subemarginate. 

 Length 15.0 mm.; width 6.3 mm. Washington State (near Fort Van- 

 couver) ad jecta Lee 



Body oblong-suboval, rather feebly convex, moderately shining, metallic 

 green, the central parts of the pronotum and a broad median part of 

 each elytron nearly from base to apex, deep indigo-blue, the elytral 

 suture narrowly cuprascent, shading into green, the side margin more 

 broadly brassy-green becoming cupreous posteriorly; under surface 

 pale cupreous, with feebler greenish reflection; head very densely 

 punctured throughout, with some small irregular smooth areas, the 

 eyes not prominent; antennae black, with more or less cupreous reflec- 

 tion; prothorax not quite twice as wide as long, the sides moderately 

 converging and nearly straight to well before the middle, then strongly 

 rounding and convergent to the apex; surface barely at all impressed 

 along the median line, broadly, longitudinally impressed near each 

 side, coarsely punctured, very densely almost throughout laterally; 

 elytra about twice as long as wide, scarcely wider than the prothorax, 

 the sides parallel, rounding and converging in rather less than apical 

 third, the apices broadly rounded, not at all sinuate, the sutural angle 

 right, not prominent; juxta-sutural supplemental ridge much narrower 

 than the first normal costa though almost equally elevated ; intermediate 

 ridges low, narrowly smooth, the sublateral ridge very strongly elevated 

 and conspicuous, the concave intervals strongly, transversely rugose; 

 under surface finely, not densely but rather strongly punctate, the pro- 

 sternum simply flattened medially, punctate anteriorly, more acuminate
