20. Oxycarenus bicolor Fieber, Rhynchotographieen, 39, 1851.

Thirty-three specimens, Fadian, Aug. 19, on Sida, Swezey ; one specimen, Barrigada, June 12, Usinger; two specimens, Fullaway (1182).

Described from India and since recorded by Esaki from Saipan and Palau (Sixth Pacific Sci. Congr., Proc. 4: 411, 1941). I have two Peleliu specimens which are smaller with pale at apices as well as at bases of coria and with apical margin of membrane faintly paler. A pair from Laloki, Papua, have the costal margins generally pale and agree with lugubris as described by Distant (Fauna Brit. India, Rhynch. 2:44, 1904). The Guam series is very black including the membrane, with bases and subapices of coria but not clavi, acetabula, ostiolar canal and hind tibiae at middle, white.
