. Brigham Young University science bulletin. Biology -- Periodicals. 232 Brigham Young University Science Bulletin with the allotype. 9 June 8, 1958, Galena Creek, alt. 6200 ft, Washoe County, Nevada (F. D. Parker). This species is a predaceous type, and I suspect it may feed on some phytophagus species of the pine. Phytocoris hesperellus, new species Fig. 264 Runs in the key to the couplet with hesperius Kngt, from which it differs in the shorter first antennal segment, which is not equal to width of head plus width of vertex. Male. Length mm, width mm. Head: width mm, vertex .37

Male. Length mm, width mm. Head: width mm, vertex .37 mm; pallid, frons with weak reddish striae, clypeus with reddish brown on middle and sides. Rostrum, length mm, reaching upon seventh ventral segment. Antennae: segment I, length mm, set with white bristles, the length of which just equal diameter of segment, ventral surface fuscous, above with white near base, marked with red- dish brown marks, two large white spots on apical half; II, mm, yellowish brown, with white annulus at base, and two pale yellowish spots on dorsal aspect near the white annulus; III, .48 mm, fuscous, yellowish at base; IV, mm, fuscous. Pronotum, length .88 mm, width at base mm; disk and calli white, basal edge of disk white, lateral margins and more broadly at basal angles blackish, sub-basal mar- gin including four tumid points, black, also with tufts of brownish black scalelike hairs; propleura black, ventral margin white. Mesoscutum nar- rowly exposed, covered with silvery sericeous pubescence. Scutellum fuscous, basal angles and narrow apex, pallid. Dorsal surface clothed with pale and fuscous, suberect simple hairs, interspersed with recum- bent and appressed, silvery sericeous pubes- cence. Hemelytra pallid, shaded and marked with fuscous; embolium and outer half of cor- ium, clavus excluding margins of commissure, and cuneus except outer white margin, fuscous.
