NORTH AMERICAN COEEOPTERA.

broad, but acute; tbe carina extending two-thirds to apex, disc convex, median 
line smooth in front, surface asperately punctate in front, sparsely punctate pos- 
teriorly ; elytra as wide at base as the thorax, but evidently narrowed from the 
obtuse humeri, disc striate, striae finely puuctate, intervals slightly convex, finely 
moderately closely punctulate; prosternum not closely punctate, a feeble trans- 
verse impression in front, lobe obtusely prominent, coarsely and closely punc- 
tate, the sutures very narrowly double, but not at all excavate, propleune less 
shining, very minutely and densely punctulate; metasternum and abdomen 
densely and finely punctulate ; legs testaceous, the femora darker. Length 2.25 
mm. ; .09 inch. 
The two specimens before me, which seem to be male and female, 
exhibit no ventral sexual characters. One % from Washington has 
entirely piceous antenme, a very faint humeral spot, the subapical 
more distinct ; that from Nevada has no elytral spots, and the second 
and third joints of the antennse pale. A third from Nova Scotia, 
probably representing a distinct species, has the elytral spots well 
marked as in Mehheimeri, and the three basal joints of the antennse 
pale. In the absence of a male it is for the present placed with this 
species. 
Occurs in Nevada, Washington (and Nova Scotia?). 
C. gradariiis n. sp. — Obloug, feebly convex, piceous-black, subopaque, 
faintly bronzed, surface finely cinereo-pubescent, more evidently in the depression 
near the hind angles; antenme black, slender, feebly serrate; front slightly im- 
pressed, rather coarsely and roughly punctured ; thorax very little wider than 
long, narrowed in front, sides posteriorly straight, in front gradually arcuate to 
apex, apical border sinuate, slightly elevated at middle and prolonged over the 
head, hind angles broad, but acute, the carina extending two-thirds to apex, disc 
convex, asperately puuctate in front, more finely and smoother posteriorly; ely- 
tra as wide at base as tbe thorax, humeri obtuse, sides feebly arcuate, apex ob- 
tusely rounded, disc striate, strife punctulate, intervals feebly convex, punctulate ; 
prosternum sparsely punctate, shining, a feehle transverse impression in front, 
lobe not prominent, obtusely rounded, coarsely puuctate. prosternal sutures 
simple, without trace of excavation, propleurfe subopaque, densely finely punc- 
tulate ; metasternum and abdomen closely finely puuctate; legs rufo-testaceous, 
femora darker. Length 2 mm. ; .08 inch. 
The male shows iio sexual characters on the ventral segments, the 
female, however, has a finely pubescent, oval spot at the middle of 
the second segment. 
This species is the one I had thought identical with dermestoides, 
but a closer examination shows it to be our equivalent, on this con- 
tinent, of curtvs of Eurojie. The sinuation of the apical border of 
the thorax, although sufficiently well marked in comparison with the 
others of the group, is less distinct than in cncidlatus. The denser 
silken pubescence of the hind angles of the thorax is rather a con-
