85. Nesonannus saileri , new species.

Head half again as broad as long, 26: 17; convex above, the surface naked and finely granular. Tylus distinctly set apart by a suture, even at base, parallel-sided, convex, and polished, with two erect bristles on either side. Eyes small, about as long as anteocular portion of head and about one third as wide as interocular space, 5: 16. Ocelli distinct, one fifth as wide as an eye, widely separated from each other, being contiguous to inner margins of compound eyes. Antenna! proportions 3: 5: 14: 17, the first two segments with short sparse hairs, the third segment with several bristles as long as the segment, inserted near base; fourth segment with several bristles longer than the segment. Rostrum and thoracic sterna obscured in the unique type.

Pronotum feebly convex, the surface finely shagreened, humeral angles narrowly rounded, hind margin feebly concave. Scutellum with sides ·concavely sinuate before middle, convex beyond middle and abruptly narrowed and briefly, roundly produced at apex.

Hemelytra less than twice as long as width of pronotum, 70: 40; costal margin thicker than hind femur, deeply impressed along inner margin; terminating along embolar suture and curving upward at end of thickened costa to form a long, narrow cell. A small cell beneath this beyond middle and two larger discal cells beyond basal discal cell and between R+M and Cu. Apical area with two free veins reaching apical margin and a third innermost vein curved outward to enclose a large discal cell.

Color rather uniform fulvous above with the membranous areas of hemelytra paler, the under surface and appendages fulvo-testaceous. Eyes and ocelli tinged with reddish.

Length (measured from above in a single plane) 1.43 mm.; width (pronotum) 0.66 mm.

Holotype male, Barrigada, on hau, July 22, Swezey .

This is the first schizopterid to be recorded from an oceanic island in the Pacific but I have seen another species (apparently not congeneric) from Fiji. I take pleasure in dedicating this species to Dr. R. I. Sailer, hemipterist at the U. S. National Museum, whose generous assistance has greatly facilitated my recent work.
