to be larger and of rather more robust outline. It is black, with 

 a feeble violaceous tinge, the concave margins of the elytra more 

 strongly violaceous. The sides of the prothorax are oblique be- 

 hind and very feebly sinuate. Length 15-16 mm. 



Oregon. I have assumed that fulleri, which was attached to 

 marginatus as a variet3^ is in reality a distinct species with six- 

 teen elytral striae, and not fourteen, which is the condition in 

 marginatus and allied metallic species. It is, of course, quite 

 possible that my assumption in regard to the number of elytral 

 striae may be wrong, as Dr. Horn states that the striae in his 

 group " II A " do not exceed fourteen in number. In any event, 

 whether classed with margiriatus or dissolutus, there can be very 

 little doubt of the specific validity of the form under consideration.

Strongly ventricose, polished, the head and pronotum not 

 alutaceous ; body deep black, the pronotum with a feeble bluish 

 reflection, the reflexed side margins of the elytra violaceo-metallic 

 in lustre. Head moderately stout and elongate, nearly smooth, the 

 supra-orbital ridges fine posteriori}^; gense feebly developed, the 

 notch minute and angulate ; antennae fully f as long as the body, 

 slender, the basal joint but slightl}^ stout and much shorter than 

 the next two. Prothorax slightly wider than long, strongly 

 dilated and rounded anteriorly, more narrowl}^ rounded at the 

 middle, the posterior sinuation deep ; sides becoming straight 

 and parallel in basal sixth ; angles right but bluntly rounded ; 

 base narrow, not quite ^ the maximum width and much narrower 

 than the head; disk feebly convex, the median line rather dis- 

 tinct ; sublateral impressions short and feeble ; lateral margins 

 rather deep and strongly reflexed. Elytra short and inflated, ^ 

 longer than wide, 3 times as long as the prothorax and nearly 2^ 

 times as wide, rather full and strongly rounded at the humeri ; 

 reflexed margins moderate, coarsely punctured ; disk strongly and 

 evenly convex, the fourteen striae rather broadly and deeply im- 

 pressed and almost perfectly even throughout the entire width, 

 the punctui'es moderately coarse ; intervals convex, feebly sub- 

 interrupted, more obviously toward tip. Length 12.5 mm.; width 

 6.0 mm.
