35. Hadrocranella pallidicoxa , new species ( fig. 6 ).

Body and appendages without long, erect hairs, the head and pronotum largely clothed with a dense coat of appressed pubescence, antennae with very short, fine subappressed hairs, middle and hind legs scarcely, very inconspicuously pubescent. Front coxae, trochanters and femora with longer, erect hairs most of which are shorter than leg diameter.

Head one fourth longer than broad across eyes, anterior lobe with an anteriorly bifurcate glabrous area at middle of postantennal region. Hind lobe evenly convex and evenly rounded behind, not impressed. Antennae about half again as long as body, 162: 105; proportion of segments one to four as 68: 60: 25: 9; slender throughout. Proportion of rostral segments, 15: 7: 10, the first segment moderately thick and curved, second strongly swollen, thicker than first, third very slender, slightly curved apically.

Pronotum about as broad across humeri as length of head, one fourth longer than broad, the anterior lobe one third as long as posterior lobe, with a conspicuous, tripartite glabrous area on either side. Hind lobe moderately elevated with an ill-defined depression along middle, its posterior margin concave before mesonotum. Mesonotum small, convex, two thirds as long as broad and briefly, broadly angulate posteriorly without a spine. Metanotum with a distinct, slender, tapering, pubescent spine directed posteriorly and dorsally about on a level with hemelytra, scarcely longer than mesonotal disk. First abdominal tergite with a relatively short, erect, stout, pale spine bent backwards and rounded at apex.

.

Hemelytra long and slender, five times as long as greatest width, the venation as in Emesopsis (Hadrocranella) neptunis McAtee and Malloch . Abdomen about three times as wide subapically as subbasally. Legs very long, the hind femora exceeding tip of abdomen by three fifths the length of abdomen, very feebly thickened apically. Front legs without visible spines.

Median posterior process of male genital capsule broad and curved upward and outward on basal half, slender, tapering, and bent upward apically. Claspers long, broad, slightly narrowed subapically and rounded at apex, bent slightly inward towards the apex. Female abdomen simply tapering to subtriangular apex.

Color brown with gray pubescence on head and pronotum. Hemelytra pale and hyaline with brown veins on basal half except for extreme base, the stigma very pale fulvous. Cells with brown markings as follows: along outer side of main vein beyond level of apex of metanotal spine, narrowly and somewhat reticulately in elongate corial cell, generally at middle of hemelytron, at base of discal cell, broadly and subtriangularly at middle of discal cell with a broad hook-shaped pale area intruding from inner side, narrowly along lateral and apical margins of discal cell, along other veins in apical portion of hemelytron, and at middle of two apical cells. Antennae pale with fuscous annuli basally, subbasally, at middle, and subapically on first segment, subbasally on second segment and only vaguely elsewhere. Front coxae entirely pale or very faintly embrowned subapically, femora lightly infuscated on basal half, a little beyond middle, and broadly subapically. Tibiae brown subbasally. Middle and hind legs pale, the femora fusco-annulate a little beyond middle and subapically and the tibiae subbasally.

Size: length 5 mm.

Holotype male, Dededo, May 11, on Cycas, Usinger ; allotype female, three paratypes, Machanao , June 4, Usinger ; three paratypes, Mt. Tenjo , May 3, Usinger ; one paratype, Barrigada, June 12, Usinger.

Allied to obsoletus McAtee and Malloch from Singapore and medusa Kirkaldy from Fiji, but these species have distinctly fusco-annulate front coxae and the hemelytra are scarcely more than three times as long as broad. Horvath's name has been used in a generic sense because these Oceanian species differ in so many characters from the typical Emesopsis .
