Each measurement of body is as follows: tip of head to end of abdomen 1.65 mm., wing length 2.15 mm., wing expanse 4.85 mm. and thorax at widest part 0.55 mm.. The head is subtriangular in form, compound eyes darkbrown and easily recognized. The antennae are very long and feathery, the total length of which is about 1.65 mm., and composed of 10 segments, each of which is distinct. The basal segment is short but very broad, and the width and the length almost similar. The second is much narrower than the first and is much longer. The third is somewhat longer than the second. The third to the tenth are subequal in length, but the fifth somewhat shorter and the seventh longer. The first segment bears rather short hairs, and the others have many hairs. Following are the measurments of the antennal segments: [table] The legs similar, brown, the posterior pair the largest, each segment covered with may stout hairs. The tibia slightly more than the trochanter and femur combined. The tarsus shorter than half the length of the tibia with two digitules on the outside of its bottom. The elow narrower. The tibia has two stout spines on the inner side of its bottom.
