81. Psallops oculatus , new species ( fig. 23 , a, b).

Head broader than long, 21:17; produced in front of eyes for a distance less than half as great as length of an eye, 5: 12; eyes very large, wider than interocular space at narrowest point, 7: 6; the narrowest point being at basal fifth of head before which inner margins of eyes gradually round to insertions of antennae near front margins, and behind which they abruptly diverge to hind margin. Upper surface of head finely granular, with stiff, erect hairs posteriorly, and finer, anteriorly directed hairs anteriorly. Rostrum reaching to apical third of abdomen, the first segment reaching to apical third of front coxae; proportion of segments 12: 14: 11: 10. Proportion of antenna! segrrients, 8: 24: 11: 10; the first two segments finely pubescent, the last two with additional erect hairs.

Pronotum with callosities scarcely elevated. The entire pronotal disk covered with small elevations which are conspicuous only when the light casts a shadow, with backwardly directed, curved hairs arising from each, these hairs much longer individually than the distance between hairs.

Scutellum and hemelytra except costal margins less densely but just as conspicuously clothed with bristlelike hairs, the hairs arising from conspicuous elevations on clavus and corium. Pubescence of cuneus shorter and finer.

Color ferrugineous on head and pronotum, the eyes and pronotal disk and pubescence brown. Rostrum reddish at base, pale at middle and brown at apex. Antennae pale, ochraceous, the last two segments infuscated. Mesoscutum broadly brown at basal angles and at middle. Scutellum brown at middle of base, white elsewhere, tinged with red laterally at base. Clavus and corium white with brown elevations from which the pale fulvous hairs arise. Cuneus deep brown on basal half, then tinged with reddish, and white at apex. Membrane most densely clouded at base, veins posteriorly white. Under surface reddish with pale base and middle of abdomen. Ostiolar areas white. Legs white with red or red-brown apically on front femora and on apical half of hind femora except for white extreme apices. Bristles of tibiae white.

Size: length 2.4 mm., width (hemelytra) 1 mm.

Holotype female, Machanao, June 4, on Asplenium nidus, Usinger .
