NORTH AMERICAN COLEOPTERA.

with a vague costa each side, basal depression feeble, surface imbricately sculp- 
tured with a pubescent spot in the basal depression, a larger spot behind this not 
reaching the middle, exterior to the end of which is a very small spot, one-third 
from apex a small I'ound spot; body beneath more shining than above; proster- 
nal lobe rather broadly and deeply emarginate, intercoxal process broad, parallel 
and with rounded apex, propleurse finelj’ punctate and strigose, sparsely pubes- 
cent; metasternum at sides densely punctate and with the outer half of coxal 
]>late sparsely pubescent. Abdomen sparsely punctate, more densely at sides of 
first two segments and somewhat strigose, with sparsely pubescent spaces on the 
first two segments midway between the middle and side and on the third seg- 
ment at the side, vertical portion of segments sparsely pubescent; pygidium 
coarsely punctate, indistinctly carinate ; claws broadly toothed at middle. Length 
.18— .20 inch. ; 4.5 — 5.5 mm. 
Male . — Prosternuin densely jumctate, finely pubescent, the pubes- 
cence extending on the front of the inetasternuin ; first ventral seg- 
ment slightly flattened at middle, not pubescent ; anterior and middle 
tihiie distinctly mucronate. 
Female. — Unknown. 
This species is not especially conspicuous among those with ornate 
elytra. With the form of fallax or egenus, the markings, when per- 
fect, resemble those of obsoleto-guttatiis, and from any of them the 
structural characters either of the antennae, legs or prosternum will 
.separate. 
Hab . — The few specimens examined were collected by Belfrage in 
Texas, probably at Waco. 
.4. oruatiilii»$ n. sp. — Form of egemis, but a little stouter, piceous, elytra 
somewhat shining, ornamented with pubescent spaces, thorax opaque. Antenna* 
attaining the middle of the thorax, piceous, serrate from the fourth joint; head 
convex, with a very feeble impression of the occiput, front convex, indistinctly 
punctate, smoother at middle. Thorax a little wider than long, sides regularly 
arcuate, margin absolutely straight, not deflexed in front, hind angles rectan- 
gular^ without trace of carina, disc convex without depressions, merely slightly 
concave along the side, surface punctate, obliquely strigose at middle, longitudi- 
nally at the sides; scutellum transversely carinate ; elytra sinuate behind the 
humeri, broadened behind the middle, apices rather obliquely rounded without 
serrulation, disc depressed at middle, a very vague costa each side, basal depres- 
sions feeble, surface indistinctly imbricate, slightly strigose at the sides, with 
pubescent spaces of sparsely placed silvery white hair in the basal depression, a 
transverse band behind these, then a longitudinal band reaching the middle 
bending obliquely outward and backward, apical third entirely pubescent, the 
anterior edge oblique on each side; body beneath with distinct aeneous lustre; 
prosternal lobe broadly and deeply emarginate, intercoxal process slightly broad- 
ened behind the coxae and obtuse at apex, propleurae feebly punctate; metaster- 
num at sides asperately punctate. Abdomen sparsely finely punctate, a slight 
pubescent area at the sides of the third segment, the vertical portions of the
