The species is also recorded in the literature from Washington by 

 LeConte (1857), from Utah, New Mexico, and North Carolina by 

 Horn (1886), from Pennsylvania by Hamilton (1895), from South 

 Dakota by Burke (1918), from Kansas by Chamberlin (1926), and 

 from Ontario, Canada, by Evans (1895). Some of these records are 

 probably taken from erroneously identified or mislabeled specimens. 



Hosts. — Burke (1918) records this species as breeding in the bark 

 and sapwood of dying and dead limber pine (Pinus flexilis James) 

 and western yellow pine (Pinus ponderosa Lawson). Mundinger 

 (1924) states that it breeds in spruce (Picea sp.) in New York; 

 Bedarcl (1938) records it breeding in Douglas fir (Pseudotsuga taxi- 

 folia (LaMarck) Britton) in Idaho, and Chamberlin (1926) gives 

 the hosts as pinon (Pinus edulis Engelmann) and northern white pine 

 (Pinus strobus Linnaeus). 



The color in the depressed punctured areas on the dorsal surface 

 of the body varies from purplish cupreous to bronzy green, and on 

 the front of the head in the males from bright green to bronzy green, 

 with a more or less cupreous reflection. In some examples the sides 

 of the pronotum are parallel and sinuate at the middle, the anterior 

 margin arcuately emarginate without any indications of a median 

 lobs, and the surface with three more or less distinct depressions 

 on each side, two near the median sulcus and one near the lateral 

 margin. The sides of the elytra are nearly parallel or slightly 

 diverging from the humeral angles to behind the middle. The emar- 

 gination at the apex of the last visible abdominal sternite of the 

 females is variable in size. The length is from 10 to 13 mm. 



Mannerheim sent the specimens collected on Kocliak Island, Alaska, 

 to Motschulsky, who described them under the name of cicatricosa, 

 which Mannerheim (1853) placed as a synonym of trinervia Kirby.

Male. — Moderately elongate, slightly depressed above, rather strongly shining, 

 piceous with a faint purplish tinge on the smooth, elevated spaces, bronzy 

 cupreous in the punctured areas ; beneath brownish cupreous, slightly greenish, 

 more strongly shining than above ; legs bronzy green to greenish purple. 



Head golden green in front, becoming slightly piceous on occiput, with two 

 small, smooth callosities on front, and a short, broad, smooth carina on occiput; 

 front flat ; surface coarsely, deeply, confluently punctate, rather densely clothed 

 with long, erect, inconspicuous hairs ; clypeus deeply, angularly emarginate in 

 front, arcuately rounded on each side. Antenna bronzy green, gradually nar- 

 rowed to apex ; intermediate segments compact, distinctly wider than long, 

 broadly rounded at outer margins ; third segment nearly as long as following two 

 segments united. 



Pronotum nearly twice as wide as long, slightly narrower at apex than at 

 base, widest near apex; sides strongly, arcuately converging at apical angles, 

 sinuate and slightly, obliquely converging from near apical angles to posterior 

 angles ; anterior margin arcuately emarginate, with an obsolete, broadly rounded, 

 median lobe; base slightly, arcuately emarginate on each side, median lobe 

 rather strongly produced, and truncate in front of scutellum ; disk moderately 

 convex, uneven, with a shallow, broad, median sulcus, limited on each side by
