The labrum simply emarginate with an impressed longitudinal line in the middle; the last joint of the exterior pal pi is the largest and almost securiform. The body nearly forms a parallelopiped; the head is almost as wide as the thorax, and the elytra are strongly striated and frequently carinated laterally. The mandibles are arcuated inferiorly 00 the internal margin, and then as if truncated and terminated in a point. The species known are from America( 1 ). Those have very obtuse mandibles, emarginate at their extrem-ity, or unidentate beneath. LwiNus, Lat. The last joint of the exterior palpi largest and almost securiform; tarsial palette of the males broad, suborbicular, and formed by the two first joints, the first of which is very large(2). BADISTER, Clair.-.!lmblychus, Gyll. Last joint of the exterior palpi oval; that of the labial palpi merely somewhat thicker, and frequently terminating in a sharp point; tarsial palette forming a long square, and composed of the three first joints( 3 ). The last of the Patellimani, or those which constitute the second general division, have their head suddenly narrowed behind the eyes, and as if distinguished from the thorax by a sort of neck or pedicle. It is frequently small, with very protuberant eyes. In several, the ligula is short and projects but little beyond the emargination of the mentum. Here, the emargination is edentate; the mandibles are toler~y stout, and the labrum is strongly emarginate and almost bilobate. Such is the (1) See Dej. Spec. II, 283.
