NORTH AMERICAN COLEOPTERA.

shorter and more obtuse than in the other species with 7-jointed 
funicle, in this respect resembling rather ^4. pyri, ulmi, ornatus, etc., 
of Europe. In fact, the two species belonging here, one of which 
is introduced from Europe, are more characteristic of the fauna of 
that continent than our own. 
The two species are readily distinguished as follows: 
More robust, anterior thighs bideutate, pubescence more squamiform. 
iiebiilo^iiiis Lee. 
More slender, anterior femur with a large triangular tooth, pubescence piliforni. 
poiiioriim Linn. 
\. iiebiilosiis Lec. — Oval, brownish piceous ; pubescence dense, rather 
squamiform of a grayish, brown or fawn color and intermixed with very fine, 
short hairs, forming distinct patterns on the elytra. Beak long, slender, mod- 
erately curved, quadristriate, lateral striae deeper and longer, punctured and 
scarcely pubescent. Antennae inserted remotely from the apex, rather long and 
slender ; scape slender, paler than the rest; second joint of funicle slender and 
longer than the third ; joints 3-4 slightly elongate, longer than the following 
joints. Eyes convex, posterior margin free. Head convex, pubescent; occiput 
more finely, front more coarsely and densely punctured. Prothorax more than 
one half wider than long; sides more strongly rounded in front, strongly nar- 
rowed anteriorly; apex feebly constricted and impressed at the sides behind the 
anterior margin ; surface evenly, densely and rather coarsely punctured, rather 
sparsely pube.scent with three narrow, paler lines. Elytra one-fourth wider at 
the base than the prothorax, oblong, sides feebly rounded and gradually nar- 
rowed to the tip, which is conjointly rounded ; strife impressed, |iunctures coarse 
and rather closely placed; interspaces convex, punctulate; scutellum white; the 
pubescence is arranged as follows : a trapezoidal basal space, a double curved 
band commencing below the humerus and extending obliquely to the middle of 
the suture, thence curving outward in a transverse direction to the outer margin ; 
within the space included is another triangular area of pubescence; underside 
of body and head clothed with squamiform pubescence. Abdomen less densely 
and more coarsely pubescent, pygidium very little ( '^ ) or not expo.sed (f). 
Legs moderately stout, thighs clavate, anterior bidentate, internal tooth lofig, 
outer tooth small, triangular and connected with the former at the base. Tibiae 
rather shorter and stouter than usual ; anterior pair curved near the base, pos- 
terior near the apex : armature strong. Tarsi slender, pubescent beneath ; claws 
armed with a rather short tooth, which is submedian on the anterior tarsi and 
becomes almost basal on the posterior. Long. 3.75—4.25 mm. ; .15— .17 inch. 
Male. — Pygidium carinate, depressed at the sides, fifth ventral 
segment feebly lobed at the middle. 
Eema/e.— Pygidium convex, fifth ventral segment bilobed at the 
middle. 
Hub. — Ohio, Michigan, Illinois, Missouri. 
Varies in the ground color from pale ferruginous to almost black, 
and also in the patterns of pubescence. The external cusp on the
