- 1. Jamitettix:guamensis, new species (fig. 10, a-e). Crown slightly conically produced in front, finely rugulose with the rugae radiating from the apex of crown; two faint and somewhat irregular transverse carinae below the ocelli; posterior margin broadly, circularly incised, nearly parallel to anterior margin. Face faintly rugulose; postclypeus narrow, slightly longer than broad; the dorsal margin nearly three times as wide as the ventral margin; preocular region broad; juga nearly semicircular in outline. Pronotum nearly twice as broad as its median length; the anterior margin produced beyond the anterior margin of the compound eyes; posterior margin shallowly excavated, with the entire surface finely transversely rugulose. Mesonotum about twice as broad as long, anterior area smooth; posterior area finely rugulose. Last ventral segment of. the female but little longer than the penultimate; posterior margin slightly notched at the median line; the posterior border shallowly crenulate. Male plate broadly triangular basad, produced caudad into acuminate processes which curve dorsad. Pygofer fairly stout, exceeding the plate slightly, ·with about a dozen stout setae. Internal male genitalia: aedeagus elongate, tubular; styles slender, elongate, almost as long as the plates, broadly curved, meeting on the median line caudad; lateral processes short, stout, the apices curved laterad. General color olive-buff with the face, crown, pronotum, and mesonotum heavily mottled with blackish fuscous. Venter and legs heavily spotted with blackish fuscous. Tegmina translucent, olive-brown; veins brown. Holotype female, Upi Trail, May 5, Usinger; allotype male, Machanao, June 30, Swezey; paratypes: one female, Upi Trail, May 5, Swezey, one female, Sinajana, June 8, Usinger. This species differs chiefly from kotonis Matsumura in much heavier, darker markings and in the decidedly different genitalia. In kotonis, the last ventral segment is broadly excavated; in guamensis, the last ventral segment is slightly notched.
