92 BULLETIN BROOKLYN ENTOM. SOC. VOL. VI. January 1884) 
Fulgida Say, Red cupreous, brilliant, highly polished, beneath hairy 
green; head rugose hairy and green in front; labrum short three- 
toothed; thorax rugose, impressed lines blue; elytra densly and strongly 
punctured, a dilated, humeral lunule, a broad refracted middle band 
and apical lunule. In some specimens the middle band of the elytra 
is slightly dilated along the margin, but never united with humeral or 
apical lunules. Form more slender than that of the preceeding ones. 
Occurs in Kans., Nebr., Dak., and Cal., on the upper banks of rivers 
at some distance from the water among the buffalo grass.

Senilis Horn. Black, opaque, beneath green; head hairy, granulate 
rugose; labrum obsoletely three-toothed; thorax short, slightly narrowed 
behind; elytra behind the humeri gradually broader, markings broad, 
a humeral lunule obliquely prolongated, the middle band enters at a 
right angle to the margin, and bends rectangularly, the longitudinal 
portion being longer, apical lunule. Occurs in Cal, (San Diego) 
Nev., Utah. Length 12 mm,

Hyperborea Lec. Dark cupreous, beneath green; head rugose, striate, 
and scarcely hairy in front; labrum short, one-toothed; thorax sub— 
quadrate, little convex, densely rugose, sides hairy; elytra behind the 
base a little broader, granulate punctate, humeral lunule obliquely 
prolongated, sometimes so as to touch the angle of the middle band: 
behind the lunule is a white margin which extends to the tip, obtusely 
dilated near the tip where it represents the apical lunule; the middle 
band arises perpendicularly from the white margin, bends backwards 
at an obtuse angle, runs obliquely nearly to the suture and ends op- 
posite the dilatation of the white margin, the hind part of the band is 
straight and gradually clavate, In some specimens the marginal line 
is interrupted in front of the apical lunule, which thus becomes iso- 
lated, ‘The markings of this species vary in their width, in Dr. Le- 
conte’s cabinet two specimens have the humeral lunule and the middle 
band so expanded as to become confluent and by these varieties it was 
shown that Cz. imbata||Say was also but a variety of Ayperborea, 
while it bears a quite different aspect compared with the typical 
hyperborea. Occurs in Hudson Bay Territory and Oregon, Length 
12 mm.
