middle acetabula of the left side and only 2 pits on either side of cleft on the right side. There is one obscure pit on top of each posterior acetabulum.

Hydrometra Reuteri LETHIERRY and SEVERIN, Catalogue General des Hemipteres, III, p. 54. (See KIRKALDY in Ann. Soc. Ent. Belg. 1900, p. 434). In describing this species from Addah, Africa, DR. REUTER says this species is related to H. ambulator STAL but differs by its larger eyes, more slender and longer second antennal segment and in the color of the hemelytra. Various syntypes have been examined. There are two in the Museum at Perth, Scotland, where, through the kindness of Mr. RITCHIE the senior author was permitted to examine them. There is one also in the KIRKALDY collection at the U. S. National Museum. The National Museum of Hungary has specimens under this label from „Africa or., Katona", „Pangani 1905 V." and „Guinea, Addah". The British Museum has specimens labeled: ,,Abyssinia, Small stream between Hawash and L. Zwai Circa 6000 ft. 30. X. 1926. J. Omer Cooper", „Abyssinia Stream west of Zaquala 27, XI, 1926. J. Omer Cooper", „Abyssinia, River Hawash at Bridge 28, XI, 1926. J. Omer Cooper", „Abyssinia Katere River XI, 1926. J. Omer Cooper", „Abyssinia, Adda shores of Hora Harsadi 3, XII, 1926. J. Omer Cooper". There are also some female specimens in the Paris Museum which we believe belong to this species. They come from „Nord de Sokoto. Birni nKonni (Mission Tilho) Dr. R. Goillard. 1910" and „Dahomey, env. de Porfo-Novo. Waterlot, 1908". This species therefore has a distribution entirely across the middle of Africa. In the syntypes there are four longitudinal lines in a row on the hemelytra and two longitudinal orange bands on the thorax separated by a purple line which is margined with black. The middle acetabula have four pits. Hydrometra hoplogastra HALE, 1925. (Plate IV). Hydromeira hoplogastra HALE, Arkiv f. Zool., No. 20, pp. 2—3, Fig. 1. C and D. The male type in ihe Stockholm Museum has no acetabular pits and was described from Laura, Queensland, Australia. HALE gives also Cape York, Queensland; Northern Territory and Northwest Australia.
