53. Trigonotylus brevipes Jakowlef , Horae Soc. Ent. Ross. 11: 63, 1880.

Five specimens, Upi Trail , May 5, on grass, Usinger ; two specimens, Atantano , Sept. 3, rice seedling plot, Swezey ; two specimens, Tarague , May 17, on grass, Swezey ; one specimen, Piti , Sept. 1, rice seedling plot, Swezey ; one specimen, Piti , Nov. 5, swept from lawn grass, Swezey ; one specimen, Guam: Fullaway (1198) .

Reuter [Acta Soc. Sci. Fennicae 36(2): 6, 1909] and Poppins (Arch. Naturges. 80A: 44, 1914) took a broad view of this species, recording it as widespread in the tropical and subtropical regions of the Old and New Worlds. Knight [Ins. Samoa 2(5): 210, 1935] questioned this but recorded the species without further comment from Samoa. My Oriental specimens from Guam, the Philippines, and Macao differ from California specimens as follows: the body is usually tinged with pink on the antennae and less conspicuously on the head, pronotum, coria, and apices of legs; the first antennal segment is shorter than width of head across eyes, 9: 12; the second antennal segment is but little longer than third, 26: 23; the first segment of hind tarsi is distinctly longer than the second and third together; and the rostrum usually reaches almost to apices of middle coxae. These characters might be considered sufficient to place it as ruficornis (Geoffroy) but the matter had best await a thorough study of this nearly cosmopolitan genus.
