The jet-black, coarsely granulate eyes are conspicuous, fused dorsally and bordered posteriorly with a narrow line of white scales or scalelike hairs. The short, thick, light brown monilifonn antennae composed of 14 segments, arise between the eyes and are about one fifth as long as the insect. The individual segments are sub- globular with a somewhat irregular row of well marked setigerous elevations near the apical fourth, each bearing a hair as long or longer than the seg- ment, other portions thickly ornamented with minute, chitinous points and with very irregular clear spaces visible as in the case of the European willow gall midge, Rhabdophaga salicis Schrk. Palps consisting of two well marked segments, the basal fusiform with several stout, subapical setae, the apical slightly longer, tapering gradually to a subacute point, well retracted, mandibles strongly excavated interiially, terminating in a conspicuous broad, internal tooth. Mesonotum dark brown or black, bordered narrowly an- teriorly and laterally with yellow- ish white, subtriangular scales and with a sparse clothing of yellow hairs posteriorly. Scutel- lum prominent, arched and rather thickly clothed with short, yel- lowish scales; postscutellum dark brown, somewhat lighter anteriorly. Abdomen dark brown w^ith the segments sparsely and somewhat irregularly, margined posteri- orly with whitish scales, terminal segment brownish. Terminal lobes pedicelled, orbicular. Wings hya- line with the membrane rather thickly clothed with long, coarse hairs; basal portion of the costa and subcosta thickened and thickly clothed with rather large, dark brown striated scales, the subcosta joining the costa at the middle of the wing, which is marked at the point of union by a white spot, the.
