on the right side of the hody the pits are similarly arranged except on the middle acetabtilum which has one pit anterior to the cleft and two pits posterior to it. F e m o r a : The anterior femora snrpass the apex of the head by about one-seventh of their own length: the posterior femora extend beyond the tip of the abdomen by about one-sixth of their own length. Abdomen: Length, 168 units; the two male processes are on the posterior half of the ventral side of the sixth segment; each process, which is abottt one-third the lengih of the segment, is about midway between the median, longitudinal, ventral line and the lateral margin and consists of a longitudinal brush of stiff hairs; the terminal dorsal process is long and sharp, about one-half the length of the segment. Described from one male bearing

1 the label: „Museum Paris, Cochinchine, Julien, 1875." Type in the Paris Mtiseum. N o t e s. The position and nature of the male processes distinguish this species from all other known species with the exception of H. Fan~ jahira, which is described as new in this paper. H. Julieni may be separated from H. Fanjahira by the fact that the latter species has two large elevations on the ventral side of the posterior half of the sixth abdominal segment, the femora are relatively shorter, and the terminal dorsal process is shorter. Hydrometra rhodesiana* sp. n. (Plate III). S i z e a n d C o 1 o r. Length, 10.8 mm (male holotype); the general color of the body brown; the basal two-thirds of head and abdomen nearly black. the pronotum with a median longitudinal frosted line bordered on each side by a dark band: hemelytra with a median longitudinal slender white line and the basal one-fottrth of the posterior margin white; the latter white streak surpassing anterior end of the other one for a short distance. Structural Characteristics. Head: Length. 110 units; the ratio of the anteocular part of the head to the postocular part is given in the formula AO:PO: :67: 31; the dorsal interocular groove, broad and shallow, about equal in length to the diameter of an eve: the ventral interocular groove is broader and deeper than the dorsal groove; the clypetts is
