6. Empoasca fuscovitta , new species ( fig. 28 , a-c).

An ochraceous orange species with a pair of fuscous vittae which start at the clypeal suture, extend over the lateral margin of the face, the apex of the head, and are continued across the crown and the pronotum to the apex of the mesonotum.

Crown narrow, obtuse, only about one third wider than its median length; face elongate, slightly protuberant, twice as broad as median length; lateral margin of cheek straight. Pronotum nearly twice as long as the crown, as wide as compound eyes, not quite twice as wide as its median length.

Male genitalia: genital plates much elongate, only slightly narrowed to divergent obtuse apices; plates and pygofer longer than the anal spine; anal styles broad, the apices suddenly constricted to somewhat divergent and recurved processes. Female genitalia: last ventral ~egment elongate, about 1.5 times as long as its greatest width, somewhat compressed; posterior lateral angles somewhat projecting; the posterior margin with a broad, shallow U-shaped excavation which occupies about three fourths of the width of the segment; the median line with a shallow V-shaped notch which is continued anteriorly as a slight ridge.

General color ochraceous buff, paler beneath and darker above, almost ochraceous orange on the dorsal part of the head and the thorax; crown with a pair of fuscous vittae percurrent; these vittae about the same width as the paler area between; the fuscous vittae continued across the pronotum, widened somewhat posteriorly; another pair of fuscous vittae behind the compound eyes; the lateral margins of the pronotum are broadly ivory-white; mesonotum with the median line ochraceous orange, the lateral area fuscous; tegmina milky subhyaline; clavus broadly clouded with fuscous along the commisural margin; costal margin with a blackish stripe extending almost to the apical. cells; the corium clouded with smoky from the base to almost the apex of clavus; another cloud beyond the apex of the clavus and the apical area with a smoky cloud; face with a pair of lateral vittae which unite on the lower third to form a large fuscous cloud.

Length: to apex of tegmina, 2.5 mm.; to apex of abdomen, 1.75 mm.

Holotype male, allotype female, Machanao, June 30, Swezey .
