The galls (plate 11, figure 2) have been described by Doctor Thompson as solitary or clustered, ovoid, fleshy, the flesh very spongy and easily torn with the fingers. The larval cells are thin with a scarcely perceptible wall vertically and one to eight occur in a gall. The growth of the plant lifts the gall above the surface of the ground, at which time its skin bursts and it becomes foliated. Male. Length mm. Antennae nearly as long as the body, sparsely haired, pale yellowish, the basal ones reddish, the distal segments tinged with reddish; 19 segments, the fifth with a stem. Fig. 70 Rhopalomyia thompsoni; fifth antenna! segment of male and palpus, enlarged (original) three-fourths the length of the basal enlargement, which latter has a length one-fourth greater than its diameter; terminal segment variable, usually narrowly oval. Palpi; the first segment rather indistinct, subquadrate, the second long, tapering, slightly curved. Mesonotum dark reddish, submedian lines sparsely clothed with fine setae. Scutellum pale salmon, postscutcllum dark brown. Abdomen a deep brick red with heavy bands of black scales, genitalia fuscous. Wings hyaline, costa reddish brown. Halteres yellowish transparent. Legs mostly black, the coxae and base of femora a variable yellowish; claws long, strongly curved, the pulvilli longer than the claws. Genitalia; basal clasp segment long, stout, with a.
