16. Graptostethus nigriceps Stal.

Graptostethus servus var. nigriceps Stal, Enum. Hemipt. 4: 117, 1874.

Three specimens, Fullaway (1186) . Described by Stal from Guam, Ascension, and Fiji and subsequently recorded by China from Samoa, New Hebrides, and New Caledonia. Variation is great in members of this group but a Fijian example agrees well with one of the Guam specimens and confirms China's suspicions regarding the synonymy of vitiensis Kirkaldy. This species was not encountered by Swezey and me during our exploration of Guam.
