Diagnosis. Small to medium sized, body oblong and gradually widened posteriorly, dullcolored, covered with short hairs. Head cylindrical, gular region strongly excavate and formed a deep, wide furrow, in which part of rostrum and antennae lie at rest. Eyes medium sized, widely separated. Anteocular portion longer than postocular portion; antennal tubercles prominent, inner­antennal processes usually conical; each side of lower margin of postocular portion with 2 to 3 nodular tubercles ( Figs. 9 , 19 , 26 , 29, 36); antenna short, first segment thickest and subequal to 2 apical segments together, second segment longest, third segment shortest; first segment of rostrum strong, about as long as 2 apical segments together. Anterior pronotal lobe slightly shorter than posterior pronotal lobe, anterior lobe with sculpture, posterior lobe usually with longitudinal carinae, humeral angles rounded ( Figs. 1 , 4 , 25 , 28) or tubercular ( Fig. 15 ) or subspinously produced ( Fig. 31 ). All femora nearly same thickness, tibiae compressed. Posterior angles of each segment of connexivum protruded laterally or not. Claspers wide, short, bent, and blunt.
