Color.—Body rather opaque and light brown, with red oil globules scattered through the metasome; eye bright red; eggs violet or purple. Femal&.—Metasome elliptical, a little more than half as wide as long; cephalic segment considerably longer than the rest of the metasome; urosome two-fifths as long as metasome; genital segment nearly as long as entire abdomen; caudal rami six times as long as wide, each with a curved row of dorsal spinules. First antennae 8- segmented, densely setose; fourth segment of second antenna only half as long as third. Anterior por- tion of semen receptacle enlarged, sometimes reaching the a n t e r io r margin of the segment, and transversely ellipti- cal ; posterior portions not divided at center and tapered to a sharp point on either side. Ovisacs oblong oval and closely appressed to the sides of the abdomen; eggs large. Total length, 0.9-1.1 mm. Male.—Smaller than the female, the cephalic seg- ment relatively shorter; urosome 5-segmented and considerably more than half the length of the metasome; caudal rami the same length and with the same armature as in the female. First antennae 8-seg- mented, once geniculate, the setae on the first and sixth segments peculiarly modified; fourth segment of second antenna relatively longer than in the female; the five pairs of legs the same, but there is also a rudimentary sixth pair at the posterior corners of the genital segment. Total length, 0.75-0.85 mm. Remarks.—This is the only " cyclops " species of the present area whose first antennae are 8-segmented, and in matured f
