FEMALE.—The cheeks moderately enlarged behind the eyes (agamic forms) or the eyes protruding beyond the cheeks (bisexual forms); antennae of moderate length, with 14 distinct segments; the thorax of moderate size; parapsidal grooves continuous (long-winged varieties) or discontinuous (short-winged varieties); median groove lacking; mesopleuron mostly smooth with scattered punctation (long-winged forms) or closely punctate and hairy (short-winged forms); abdomen smooth and naked except for the hairs latero-basally; hypopygial spine rather broad, somewhat drawn out at the ventral tip but this tip not as long as in Acraspis; tarsal claws of moderate weight, distinctly toothed; wings long, about 1.60 times (agamic forms) or 1.30 times (bisexual forms) the body in length, or much reduced and 0.36 to 0.8 of the body in length; if the wings are long the second abscissa is curved toward the tip but does not show such an angle as is found in Acraspis, the vein ends in an angulated expansion, the radial cell is moderately long and moderately broad and clear of spots or blotches; the areolet is of moderate size or smaller; the cubital cell has a large, smoky blotch basally and is either clear or spotted apically; and the discoidal cell has a single blotch basally (which is faint in several forms); if the wings are short, the venation is more or less reduced, most so in the shortest wings; moderate-sized insects 1.2 to 3.5 mm. in length.

MALE.—Differing from the bisexual female as described for the genus; with 15 antennal segments; with the coxae and the bases of the femora darker than the rest of the legs; the smoky patches and spots in the wings much lighter than in the female.

GALL.—Irregularly spherical; or squash-shaped with short, blunt, projecting tips; or elongate club-shaped; or cylindrical bowl-shaped, or flattened and disk-like; of moderate size; always smooth and naked or
