and hairy. Length 14. 0-15. 2 mm.; width 5.6-6.0 mm. Oregon. 

 [Fort Vancouver,— LeConte] radians Lee. 



Sides of the elytra oblique posteriorly, becoming straight or feebly sinuate 

 before the tips 9 



g — Body rather stout, moderately convex, colored throughout as in lauta; 

 head ( 9 ) as in that species, except that the central more densely sculp- 

 tured divided spot is not so clearly marked ; prothorax four-fifths wider 

 than long, the sides scarcely converging and nearly straight to well 

 beyond the middle, there rounding and rapidly converging to the apex, 

 sensibly incurvate at base; apex subtruncate, broadly bisinuate, the 

 base also evenly bisinuate; surface with scarcely a vestige of impression 

 along the middle but with a small impression before the scutellum, the 

 punctures coarser than in lauta and coalescent in short sinuous lines 

 medially, coarser and densely coalescent laterally; scutejlum broader, 

 quadrate; elytra shorter, rapidly oblique at the sides in apical two-fifths, 

 the oblique sides straight, the apices broadly rounded, becoming trans- 

 verse suturally, the sutural angle right and rather blunt; surface as in 

 lauta, the costee well elevated but with the intervales more unevenly 

 though similarly densely cribrate; under surface finely, remotely punc- 

 tate medially, rather strongly and closely so laterally, the prosternum 

 flat and smooth, with an obsoletely subimpressed punctate median fine. 

 Length 15.3 mm. ; width 6.0 mm. Colorado (Boulder Co.) . aeniula n. sp. 



Body much narrower, smaller than lauta but with similar coloration and 

 sculpture, except that the green on the elytra is replaced by deep green- 

 ish-blue; head (d') similarly finely, very densely punctate and pubes- 

 cent, the eyes larger and more prominent than in the feniale; prothorax 

 as in lauta but with the sides becoming less parallel behind the middle 

 though straight, not at all incur\^ate at base as they are in cemula; punc- 

 tures for the most part isolated or simply crowded as in lauta; elytra 

 but little wider than the prothorax, as in lauta but about twice as long 

 as wide, the sides becoming oblique in apical third and feebly sub- 

 sinuate just before the apices, which are broadly subtruncate, the exter- 

 nal angles right but rounded, the truncature anteriorly oblique sutur- 

 ally, feebly undulated and with the sutural angle rather strongly spicu- 

 late; sculpture as in lauta, except that the intervales are still more 

 densely cribrate, almost opaque; under surface as in lauta but more 

 strongly and closely punctured than in the male of that species. Length 

 r c?) 14.2 mm.; width 5.2 mm. Washington State (Tacoma) . 



tacomae n. sp. 



Body rather stouter, coloration nearly as in lauta throughout, excepting 

 a broad bluish-green streak on each elytron; head nearly as in cBtnula; 

 prothorax three-fourths wider than long, the sides converging and 

 straight from the base nearly to apical third, there rounding and more 

 convergent to the apex; surface narrowly impressed and finely, densely 

 punctate on the median line anteriorly; punctures isolated, rather 

 sparse, moderate in size, coarse and unevenly confluent laterally; elytra 

 evidently wider than the prothorax, the converging sides posteriorly
