FEMALE.—The cheeks slightly enlarged behind the eyes (agamic forms) or not enlarged (bisexual forms); antennae of moderate length, with 13 or (rarely) 14 segments (agamic forms), with 14 distinct segments in bisexual forms; thorax of moderate size; parapsidal grooves continuous; median groove lacking; mesopleura (agamic forms) largely punctate and hairy, or mesopleura (bisexual forms) largely smooth and naked; abdomen smooth and naked except for the hairs latero-basally and for a microscopic pubescence on the posterior segments; hypopygial spine rather broad, rather drawn out at the ventral tip; tarsal claws of moderate weight, moderately toothed; wings always long, about 1.50 times the body in length (in both agamic and bisexual forms); the second abscissa of the radius only slightly curved at a point one-third from the tip, the tip of the vein with or without an expansion; the radial cell rather long and only moderately broad; the areolet of moderate size to small; all the cells without clouded patches or spots unless there is a mere trace of a patch at the base of the cubital cell; length 1.8 to 4.4 mm., the agamic insects varying from a small to a moderate size, the known bisexual forms of moderate size.

MALE.—Differs from the bisexual female as described for the genus (q.v.); the eyes a bit larger than in the female but barely extending beyond the cheeks; antennae with 15 segments; all wing cells clear of spots and blotches.
