Oblong, flattened insects, living on flowers, and having the ))0(ly more or less covered with flat scales of a yellowisli, hrownisli, or silvery color. ]}nt one genus, Iloplia, is found in the United States, and is represented by species in every part of our t<'rr:- tory; the males frequently differ from tho females by color as well as size, and even by the texture of the scales and hair, so tliat, whenever opportunity occurs, the sexes of the specimens found should be carefully noted. Tiie sub-tribe is known by the ligula being corneous, and con- nate with the mentum, as in the other Melolonthida; of our fauna; by the small scutellum, and by the middle coxa) 1)eing nearly contiguous. The characters of the tribe are:
