Related to O. xylina in shape and form but very distinct from
it in coloration i clytra lack the long stripes of that species, hav­
ing instead a rather indistinct, oblique, brown fascia before middle;
antennae broadly pale basally on fourth, sixth, eighth, and tenth
segments; and the fifth sternite has only a very small pale macula
each side.
MALE. Elongate-ovate, rather robust, elyt.ra slightly depressed; fUSCOllS,
densely covered everywhere with grayish-brown, fulvons, and hoary-gray varieg:tted
pubescence. Pronotum more or less distinctly maculate with brown each side near
base. Elytra with an indistinct, oblirjue, hoary (sometimes variegated with fulvous)
band from humeri to near suture at basal third, behind which is a broader, more
distinct, brown fascia reaching from beneath humeri almost to suture at middle,
lat.erally indistinctly widened, and on disk posteriorly prolonged by irregubr, forked,
brown lines to apex. Body beneath fuseollS, densely covered with hoary, [ulvons,
and brown pubescence, the latter predominating on sterna medially, the fulvons
on sterna laterally and on abdomen medially ; abdomen with five more or less distinct
series of whitish and ochraceollS streaks, one sere.3 medial, one on each lateral
margin, and one each side halfway between margin and middle. Legs fuscous,
hoary-gray pubescent, variegatecl with fulvous and dark brown, on tarsi the latter
color predominates. Antennae fuscous, bases from fourth segment roeate, fourth,
sixth, eighth, tenth, and eleventh more broadly so; covered with brown pubescence,
variegated with hoary, the pale bases and sometimes ninth to eleventh segments
entirely hoary; scape fulvous and hoary.
Hettd minutely, dcnsely punctate, with a median impressed line from occiput .
to epistoma ; front about as wide as long, narrowed from lower margin of eye to
