Sailer, Bureau of Entomology and Plant Quarantine, United States Department of Agriculture The new genus described below contains one previously named species and four new species. Cytological studies con-ducted at Columbia University under the direction of Profes-sor Franz Schrader involve one of the unnamed species. This paper is written in order to provide a name for this species as well as some information concerning its affinities to related species of Pentatomidae. The folloAving generic diagnosis is presented in considerable detail in order to reduce duplication of descriptive informa-tion for the included species. It is expected that the discovery and inclusion of additional species will require alteration of some of the characteristics mentioned. Alitocoris, new genus Form broadly oval with greatest width across third visible abdominal segment; broadly rounded posteriorly and abruptly narrowed anteriorly from humeral angles to apex of head. Noticeably convex dorsally, strongly so ventrally. Anterior portion of pronotum and head moderately declivous. Head broader across eyes than long; length about equal to width of
