Head with the front short, subvertical; the postclypeus triangular, the anteclypeus short, transverse and membranous ; mandibles short; maxillary palpi a little longer than the labial, last joint triangular; gula without mentigerous process; eyes rather finely facetted and divided each into two parts which are more or less distant from one another and united only by a smooth raised line destitute of facets. Antennae inserted before the eyes not far from the base of the mandibles ; much shorter than the body, attenuated towards the end; first joint short and thick; the second half as long as the third; third to fifth subequal in length, sixth to tenth gradually diminishing; eleventh shortly appendiculate, longer than tenth. Protborax transverse, some- what flattened above, rounded at the sides, broadest a little before the middle and narrowed most towards the base. Elytra feebly convex, not very long, more or less parallel-sided, broadly rounded at the apex. Legs rather short; femora compressed, fusiform, sometimes very shortly pedunculate at the base ; first joint of hind tarsus as long as the second and third united. Acetabula of front coxae strongly angulated on the outer side, the intercoxal process very uaiTow and for the most of its length forms a thin vertical plate ; the intercoxal process of the mesosternum also very narrow, but widened out in front. 88.
