dently strigose on the vertex. Thorax one-third wider than long, slightly nar- 
rowed at base, sides in front very feebly arcuate, thence nearly straight to hind 
angles, which are rectangular and without trace of carina, lateral margin slightly 
sinuous, disc feebly convex, a rather deep elongate oval median depression, 
widest near base, lateral oblique depressions moderate, color cupreous, the sides 
aeneous, surface closely punctate, scarcely at all strigose, the sides with a broad 
hand of yellowish pubescence covering the brassy margin ; scutelluin not cari- 
nate ; elytra feebly sinuate at the sides, very slightly broadened behind the 
middle, apices rounded and minutely serrulate, disc depressed, vaguely channeled 
each side of suture, color dark olive-bronze or nearly black in the channel, 
brassy at the sides, surface punctate and feebly imbricate: body beneath piceous, 
slightly asueous, metasternum slightly cupi-eous; prosternal lobe deeply emar- 
giuate, with a deep transverse depression, intercoxal process bi'oad, acutely oval 
at tip, propleurre roughly strigose; metasternum at sides transversely strigose. 
Abdomen sparsely finely punctate, somewhat strigose at the sides of the first 
segment, vertical portions of the segments densely pubescent ; last ventral seg- 
ment truncate and feebly emarginate ; pygidium sparsely punctate, not carinate ; 
claws broadly toothed. Length .50 inch.; 12.5 mm. 
In the five specimens examined no sexual differences have been 
observed. 
Tlie posterior tibite have a form wliich has not been observed in 
any other of our species. Near the apex the tibia is rather abruptly 
narrowed. The fringe of short bristly hairs which is observed along 
the posterior edge of the tibise in all the species in a varying degree 
is here present, but ends abruptly at the point at which the tibia is 
narrowed. 
The facies of this sjiecies is so unlike the style of those of our 
fauna, that 1 remained for some time in doubt as to the correctness 
of the locality. Recently, however, a specimen has been sent me 
from the National Museum removing all doubts.

.4. Walsiiigliaiiii Crotch. — Moderately elougate, of rather robust facies, 
but little narrowed posteriorly, color variable from bluish to cupreous and brassy. 
Anteimte short, joints longer than wide, color variable, serrate from the fourth 
Joint. Head convex, with a median depression from the occiput, which becomes 
broader on the front, a deej) transverse depression at base of clypeus, surface 
coarsely and closely punctate. Thorax one-third wider than long, sides feebly 
arcuate, lateral margin nearly straight, hind angles rectangular, without trace of 
carina; disc convex, with a median depression extending from base to apex, 
lateral depressions feeble, surface coarsely moderately closely ])unctate, without 
trace of strigosity ; scutelluin very indistinctly carinate ; elytra feebly sinuate 
behind the humeri then nearly parallel, narrowed at apical third, apices rounded, 
feebly serrate, disc rather convex, basal depressions feeble, on each side two fine 
vague costfe extending two-thirds to ajjcx, surface closely imbricately sculptured 
and with small white pubescent spots arranged as follows: in the basal depres- 
sion, one in front of middle inside of the costfe, at middle exterior to the costa.
