Mauilibltis and labium ptoiiiiiHiit; ventral segnientH hIx, free. Maudiblea aud labrum Iwiieath the cijjieua ; ventral HOgnients coniiali'. Onceuini. Tribe I-«LAPIIYR1NI. Oblonpr, not convex insects, fre(|uenting flowers, and remarkable for the long hairs of the legs and under surface; the head and thorax are also usually densely covered witli long hair. The elytra are flat, fre(|uently dehiscent, and do not cover the i)ygi- dium; the abdominal spiracles are all situated in the connecting membrane; the fifth ventral joins the propygidium, to form a ring, but is not connate with it, as in the genuine Melolonthidic; the sixth ventral is somewhat triangular, and unites with the ])ygiiliuiu to form a freely moving conical mass. The epiniera i)f the inesuthurax are very large; the mctasternum is short; the side pieces broad, with the epimera large; the anterior coxse are large, prominent; the middle ones transverse, contiguous; claws long, diverging. Antennaj with 3-jointed club. The legs and tarsi of these insects are formed as in other Me- lolonthidie, and the claws of Lichnanthe are slightly toothed at base. Lichnanthe is found in the Atlantic States, Dasydcra in Cali- fornia; both have 10-jointed antennaj. Maxillary palpi with the last joint oval, deeply excavated; labrum slightly emarffinate ; claws scarcely toothed, liroader at Dasydkha. ^' '^ I'llpi with the last joint cylindrical; labrum deeply einarginate ; tlawa with a broad basal tooth. Tribe II.âOIVCERIBTI. This tribe corresponds with the group Lasiopodes of my sy- nopsis of Melolonthidae.* Its characters
