The Museum at Copenhagen has a couple of specimens from „Sicilia, coll. Western". And the one at Yienna a series from Africa. No attempt has been made to record the many places from which this species is well known. Hydrometra eremobia KIRITSHENKO 1925. (Plate V). Hydrometra eremobia KIRITSHENKO, A. A., Revue Russe d'Entomologie, Vol. XIX, p. 5. Thanks to the kindness of Doctor KIRITSHENKO we have in the University of Kansas Collection two specimens of this species, unfortunately they are both females, so we cannot figure the male. The females, aside from color, are indistinguishable from H. stagnorum L. Hydrometra Turneri* sp. n. (Plate V). Size and Color. Length, 10 mm to 10.8 mm; the females a little longer than the males; the general color of the body is dark nearly black; pronotum, legs, spots on connexivum above and beneath, and median ventral line on abdomen may be brown; the pronotum, beak, antennae and legs brown in all the specimens, other parts mentioned above black in most of the specimens; a median longitudinal frosted stripe on posterior half of pronotum and a similar curved stripe above each of the acetabula; the pits often made conspicuous by frosty spots; abdominal tergites dull black (in two specimens dull brown). Structural Characteristics. H e a d : ( Length, 112 units; the ratio of the anteocular part of the head to the postocular part is given in the formula AO:PO: :71:32; the dorsal interocular groove narrow neariy as long as the diameter of an eye; the ventral interocular groove is about as long as the dorsal one but deep due to the elevated ridges on either side; the clypeus is conate; the rostrum surpasses the eyes a little more than half the postocular distance; the antennae have following formula: lst:2nd:3rd:4th: :16:30:125:6() (2). Pronotum: Length, 42 units (brachypterous male); a very distinct encircling row of pits parallel to the anterior margin; median longitudinal groove pitted and distinct on posterior half only, the anterior lobe with a median shallow depression instead; the transverse constriction and posterior lobe covered with pits. Metanotum : The hemelytra are short, undeveloped and not surpassing posterior end of this segment.
