very deep and conspicuous; elytra between two and three times as long 

 as wide, almost a third wider than the prothorax, straight and parallel 

 at the sides, the latter gradually obUque and becoming straight in apical 

 two-fifths, the sutural angle not prolonged though acute; surface deeply 

 crenato-sulcate as usual, with a small pale spot only slightly behind the 

 middle and another at apical sixth; under surface finely, sparsely 

 punctate, rather closely and strongly so laterally. Length 15.0 mm.;

Prothorax much narrower at apex than at base, the sides converging and 

 almost evenly arcuate throughout; upper surface golden-green. Body 

 oblong, depressed; head and disk of the prothorax coerulescent, [the 

 form of the latter assumed as above] ; head rugose, the pronotum deeply 

 punctate; elytra densely costate, the interstices [grooves] rugulose;

A — Bright golden-green; head and prothorax thickly punctured, the latter 

 with an impressed longitudinal line; elytra with deeply impressed 

 punctured lines, having a purplish tinge on each side in front, full 

 four times the length of the prothorax, cupreo-bivittate; abdomen 

 with a short gilded band on the fore border of each segment, the 

 tip cupreous. Length 1 8.0 mm. Vancouver Island . . ornata Walker 



B — Elongate, parallel, feebly convex, cuprascent above, the pronotum 

 more brilliant cupreous, the sutural and basal regions of the elytra 

 greener; under surface throughout highly burnished, deep and rich 

 coppery-red, with faint greenish tinge near the sides anteriorly; head 

 coarsely, confluently punctate, the eyes prominent, black; antennae cop- 

 pery-red basally; prothorax not more than three-fifths wider than long, 

 the sides rather more rounded basally than usual and more incurvate 

 at base; surface broadly and only very faintly impressed along the 

 middle, with the sublateral impressions wholly obsolete, the strong 

 punctures rather sparse, coarser, very deep and dense laterally; 

 elytra about two and one-half times as long as wide, nearly five times 

 as long as the prothorax but only slightly wider, the sides gradually 

 rounding and converging in apical third to the narrowly sinuato- 

 truncate apices, the sutural angle very acute but not much prolonged; 

 surface with very coarse, confusedly cribrato-punctate grooves, 

 which are about as wide as the remotely punctulate intervals, im- 

 maculate, suffusedly cupreolate; under surface finely, sparsely punc- 

 tate, minutely so medially; femora unusually minutely, sparsely punc- 

 tulate. Length 16.0 mm.; width 5.8 mm. Vancouver Island

C — Similar to the last but more elongate and rather more depressed, green » 

 the elytra suffusedly cupreolate, the under surface bright coppery-red' 

 more broadly and evidently green toward the sides anteriorly; head 

 very densely but less coarsely punctate, the eyes smaller and less 

 prominent; prothorax nearly similar, except that the median line
