Vol. XXvi] ENTOMOLOGICAL NEWS 73 Three New Species of Aphelinus (Hym.) By E. W. RUST, Assistant Government Entomologist, Lima, Peru. Aphelinus capitis sp. nov. 9. Length, 0.75 mm.; expanse, 1.7 mm.; greatest width of fore-wing, 0.27 mm. Antennal scape long and slender, reaching to top of head, slightly compressed laterally and of nearly equal cross section throughout its length except at the extremities where it tapers sharply to the articu-lations; pedicel just a trifle less than half as long as the scape and nearly half again as wide at its widest point, increasing gradually in diameter to a point just distad of its middle where it is half as wide as long; funicle joint I triangular in outline, very small and sometimes quite indistinct, being of less than half the size of funicle joint 2, which latter is of the same diameter as the pedicel and of a hit less than one-third its length; the penultimate joint is from two-thirds to four-fifths as long as the pedicel and just a shade wider, it is also three times as long as the second funicle joint which it just exceeds in diameter; the second or ultimate club joint, which is compressed laterally, is three times as long as the penultimate joint and at least one-third wider (when seen in broad outline), widest just distad of the middle from where it tapers rapidly to a blunt point. A deep constriction occurs between the two club joints separating them quite distinctly. Club, with a few longitudinal keels and (in common with the rest of the antenna) sparsely hairy. Eyes hairy. Head and rest of body very similar to A. diaspidis How. both in shape, position and number of hairs or spines and in general sculpture, except that the mesoscutum and mesoscutellum of A. capitis are faintly longitudinally striated instead of showing the slightly tessel-lated pattern of A. diaspidis. The forewings, in structure, are nearest like those of A. mytilaspidis How., but differ in that the discal cilia do not appear to be quite so plentiful as in the last named species. In A. capitis there is a greater difference in the length of the cilia on opposite sides of the hairless streak, those distad being seemingly shorter than in A. mytilaspidis and those proximad being slightly longer. The latter cilia, although of about the same numbers as those of A. mytilaspidis, more nearly occupy all of the wing surface proximad of the-hairless streak, thus producing the impression that the wing is less densely ciliated than in A. mytilaspidis. Hind wings as in other species of Aphelinus. Color : Head brownish yellow to orange yellow ; eyes blackish ex-cept with strong light through them, when they appear garnet-colored; ocelli dark red ; antennae concolorous with body or a trifle more
