The mandibles of the female are as long as the cephalothorax, and those of the male longer (figs. 461, 465). In both sexes they are inclined forward, so as to be nearly horizontal and spread apart at the ends. The lateral eyes are near together, so that they almost touch, and the upper row when seen from above is nearly straight. The palpi of both sexes are over one and a half times as long as the cephalothorax, and in the males sometimes twice as long (fig. 465). The patella and tibia together are nearly as long as the femur. The color is sometimes light yellow, but often gray, with a broken middle stripe of darker gray on the. Fig. 458.
