description: 7. Empoasca bipunctulata, new species (fig. 29, <i>a-e).</i> Crown as long as its width between the eyes, obtusely rounded anteriorly; face narrow, elongate, more than twice as long as the width between the eyes. Pronotum about twice as broad as long; the posterior margin broadly excavated. ·Male genitalia: unique; genital plate and genital styles elongate, slender, suggestive of certain species in the subfamily Jassinae; genital plate elongate, slender, the basal two thirds about the same width throughout, then elbowed, narrowed, directed mesad and ending in obtuse apices with elongate setae; genital styles not as long as the anal spine, the basal portion of about the same width, then suddenly constricted and terminating in elongate, slender flagellate processes; the lateral processes somewhat sickle-shaped, attenuated to acute apices which are directed laterad; aedeagus elongate, slender, about half as long as the pygofer, terminating in a slender process. Female genitalia: with last ventral segment about 1.5 times as broad as long; the posterior lateral angles strongly projected; the posterior border excavated in a broad U-shaped sinus; the median area projected into a broad sharp triangular tooth with a shallow median V-shaped notch. Color of the venter including the legs and abdomen pale ochraceous buff; face ochraceous orange with a pale, rather indistinct median vitta and two pairs of oblique vittae, the dorsal pair starts at the apex of the head and slopes laterad to the middle of the eyes; the ventral pair is broader and starts at the top of the median vitta and slopes laterad to the antennae; crown ochraceous orange with a pale median vitta starting about the center of the crown and terminating anteriorly in two recurved fasciae above the ocelli and extending almost to the compound eyes; behind these fasciae there is a pair of broad, short dashes directed caudad which extend from the margin of the compound eyes for about a fourth of the width of the crown; pronotum chiefly ochraceous orange; median vitta ivory-white; lateral fields broadly ivory-white; tegmina translucent with ochraceous greenish reflections; a large black spot between media and the cross veins just posterior to these. Length: to apex of tegmina, 2.75 mm.; to apex of abdomen, 2.25 mm. Holotype male, Piti, May 1, from sedges, Usinger; allotype female, Piti, May 1, from sedges, Swezey; paratype, one female, Umatac, May 14, Usinger. _This species is colored ochraceous orange and ochraceous buff. The pronotum has a median pale vitta and tegmina with a circular black spot on the corium beyond the apex of the clavus. The genitalia are quite different from any other species of <i>Empoasca</i> known to me, but the other structural characters place this species in this genus.
