more brassy. The upper surface lacks the cotton-like tufts, punctures more 

 numerous. Under parts more bronze in color, prosternum punctured and 

 sparsely pubescent; last ventral segment (PI. VII, fig. lo) very convex, nar- 

 rowed, with a deep (median), wide, rounded emargination. 



Type (^ and ? in author's collection ; paratypes sent to Mr. H. E. 

 Burke. 



Described from four specimens collected by Mr. J. Brunner at Mis- 

 soula, Montana, June i6, 1916, on Black Cottonwood (Populus fn'cho-

Poecilonota fraseri new species. Plate V, fig. 6. 



Form oblong oval, not flattened, strongly convex, longitudinally ; antennae 

 brassy purple, with numerous fine white hairs, first joint slightly longer than 

 second and one arid one half times as great in diameter; front roughly sculp- 

 tured with a broad, elevated, dark green, grooved line extending down about 

 one third the distance to the clypeus, thence dividing to form an inverted Y, 

 remainder of the front brassy violaceous with long, fine, white pubescence ; 

 a transverse ridge separates the clypeus from the front. Ground color of the 

 dorsal surface very dark violet, almost black ; thorax with a broad median 

 smooth space extending from posterior to anterior margins (very prominent, 

 being about one half millimeter in width) ; irregular elevated areas and lines 

 occupy a considerable portion of the thorax ; punctures of the thorax medium 

 in size, quite rounded near the median line, larger and more irregular in shape 

 near the lateral margins, and separated by irregular, strongly elevated, smooth 

 lines ; scutellum broad, rounded in front and sinuate behind ; lateral margins 

 of the thorax rounded, strongly constricted in front ; elytra with first four 

 intervals entire, prominent ; fifth and sixth intervals distinct near the middle ; 

 punctures fine and scattered, shoulders a little more densely punctured ; elytra 

 widest behind the middle, narrowing strongly towards the tips ; apices short, 

 strongly divergent, tips strongly emarginate (Plate V, fig. 6). Beneath pur- 

 plish-bronze, finely, rather densely, punctate except along the middle, quite 

 densely pubescent ; prosternum smooth and shining along the middle with a 

 few large punctures near the border from which protrude long, fine, white 

 hairs; last ventral segment rather broadly evenly emarginate (Plate VII, 



fig. 14)- 



Length male 13.5 to 15 mm. 

 Width male 5.0 to 6 mm. 



Two specimens (males) examined. The type collected on the 

 Eraser River in British Columbia by "Weldt" and loaned me by Mr.
