the head to the postocular part is given by the formula AO : PO : : S7 :32; the dorsal interocular groove fairly broad, of median depth and shorter than the diameter of an eye; the ventral interocular groove appears to be longer than the diameter of an eye; clypeus very bluntly conate, the rostrum attaining rear margin of the eyes; antennal formula is: ist:2nd:3rd:4th:25;54;l 14;38. Pronotum: Length, 63 units; the encircling row of pits not conspicuous and three unit spaces behind the anterior margin. The posterior lobe undeveloped with a few pits; the usual median longitudinal line present; no pits laterally. Metanotum : Hemelytra minute. C o x a e : The distance between the first and second coxae is to that between the second and third as 43 : 67; anterior and middle acetabula with two pits each; posterior acetabulum with a pit on top. F e m o r a : Anterior f emora surpassing the apex of the head by one-thirteenth their length and the posterior femora surpassing the tip of the abdomen by 7.5 percent of their length. A b d o m e n : The sixth segment of the male slightly swollen on the anterior ventral half and provided with two oval hair tufts at the extreme sides of the segment which occupy the anterior half of the margin. (See drawings on Plate III). Described from one male labelled „Caprivi Strips" „S. Africa" G. E. Hutchinson collect. B. M. 1928—395. Holotype in the British Museum. A female bearing a similar label is referred with some doubt to this species. Hydrometra Fanjahira sp. n. (Plate III). Size and Color. Length, 12.8 mm (male holotype); general color of the body is a reddish brown: a longitudinal, median, narrow, white stripe extending from the anterior margin of the eyes to the base of the pronotum; the anterior third of the pronotum and the lateral margins dark reddish brown in color; the remaining part of the pronotum brownish yellow; a narrow white band extends along the lateral margins of the thorax; ventral parts of entire body w 7 ith frosted appearance; white patches of frosting on the sides of the abdomen near the anterior margin of each segment; a broad, white, longitudinal stripe on the hemelytra. Structural Characteristics. Head : Length, 113 units; the ratio of the anteocular part of the head to the postocular part is given in the formula AO : PO : : 72 ;31; the dorsal interocular groove is slightly shorter than the dia-
