At its heart, this attitude embrangles the concepts of "need" and "want"; those fubsy fuddy-duddies with griseous imaginations believe that words no longer in frequent use will never in the future be needed by English speakers and writers more nitid than themselves.
This griseous pilosity fills all the tips of the elytra, leaving bare only the sutures, an angular notch behind the middle (which forms with that apical part of the suture a kind of hook on each elytron), and two round spots, one submarginal fronting the tip of the notch, the other larger, discoidal, behind the foot of the notch, much above the tip.
Black; the scape in front, the sides and apical margin of the clypeus, and a spot at the base of the mandibles yellow; the cheeks reddish-yellow; the antennæ ferruginous; the head covered with short griseous pubescence.
The freshest specimens have the griseous margin of the elytra, which parts from the base under the shoulder, obliquely and angularly ampliate interiorly towards the middle, where it reaches the second stria.
Black; the clypeus, mesothorax anteriorly, and the posterior tibiæ outside coarsely rugose, the roughness on the thorax consisting of transverse little elevated points; the face with a thin griseous pubescence; the anterior margin of the clypeus fringed with fulvous hairs; the cheeks have a long pale fulvous pubescence.
Black; the head and thorax very closely punctured, thinly clothed with griseous pubescence, that on the face, thorax beneath, and on the coxæ most dense and glittering; antennæ more slender than is usual in this genus, and tapering to their apex, the joints slightly subarcuate; the mandibles bidentate at their apex and with a yellow spot at their base.
Black, punctured and opake; the clypeus terminating in a sharp-pointed angle; the base and apex of the mandibles rufo-piceous; the scape ferruginous in front; the face with a thin, fine, griseous pubescence.
Black and punctured, with thin long griseous pubescence; the vertex, disk of the thorax, and the abdomen shining; the mandibles and clypeus yellow, the latter with a black bell-shaped spot in the middle; wings fulvo-hyaline, the nervures ferruginous; the tibiæ with a yellow line outside.
Head and thorax black and very closely punctured; the face covered with griseous pubescence; the clypeus with a central longitudinal carina.
Elsewhere, fantasy game devotees have rushed to the defense of periapt (a charm or amulet), which they know from the popular Dungeons & Dragons game, and geologists have pointed out the utility of griseous (streaked or mixed with gray) in describing rocks and minerals.
