Described from one male bearing the following label: „Madagascar, Region du Sud-est, Vallee du Fanjahira, Isaka, Ch. Alluaud, 1901". Type in the Paris Museum. Notes. This species seems to be more closely allied to H. Julieni, which is described as new in this paper, than to any other known species. They can easily be separated by the fact that H. Fanjahira has the large elevations on the sixth abdominal segment, relatively shorter femora. and the shorter terminal process. Hydrometra Julieni sp. n. (Plate III). Size and Color. Lciigth 13.0 mm (male holotype); the general coior of the body is a brownish yellow. Structural Characteristics. Head : Length, 120 units; the ratio of the anteocular part of the head to the postocular part is expressed by the formula AO: PO: : 75:35; both the dorsal and ventral interoctilar grooves are about as long as the diameter of an eye and are broad and "shallow; clypeus trtincate, about half again as broad as long; rostrum extends back one-third of the postocttlar distance; beginning with the basal one the ratio of the lengths of the antennal

1 segments is expressed by the following; 25:50:129 (approx.): X; the third segment, due to its curvature, could not be measured accurately; the last segment of the antennae is missing from the specimen. P r o n o t u m : Length, 59 units; an encircling row of pits parallel to the anterior margin and about three units from it; the posterior lobe with a median longitudinal row of pits on the posterior two-thirds of the lobe; on each side of the median row and also near each lateral margin is an irregular row of punctures; a row of six or seven pits near the margin of each of the propleura. Metanotum: Length, 53 units; the hemelytra are large, extending slightly beyond the middle of the fifth abdominal segment. C o x a e: The distance between the first and second coxae is to that between the second and third coxae as 35:67; all the acetabula are pitted; the anterior acetabulum on the left side of the body has four pits, two anterior to the cleft and two posterior to it; the middle acetabulum has two pits anterior to the cleft and one posterior to it; the posterior acetabultim has one or two very faintly defined pits;
