In this group the hind coxa' vary in position; the metnstcrnuni in the apterous species is very short, iiut in the winged ones long: the epipleurai do not reach the tip of the elytra in nmst of the genera, aiul in otinn's they are gradually narrowed, reaching the tip. The spreips are found uiuler bark of dead trees. Our gen
