THE CANADIAN ENTOMOLOGIST 233 A NEW GENUS AND SPECIES OF TRICHOGRAMMATID^ FROM THE PHILIPPINES. BY A. A. GIRAULT, Bureau of Entomology, U. S., Department of Agriculture. The following genus belongs to the Chaetostrichini : Pseudobrachysticha, new genus. Female. — In my table of genera runs to Brachysticha Mayr, but differs from that genus in that there is only one-ring joint and the fore wings are naked, the marginal ciliation at the apex but moder-ately long and the club is 2-jointed, the antenna? 6-jointed. More-over, in the male the club is solid. Because the single funicle joint is connected rather closely with the club, sometimes making the latter appear 3-iointed, this genus may be confused with Plcrygo-gramma Perkins, but the male is different from the female, the discal ciliation of the fore wing is absent, excepting a single line of it along the cephalic margin from venation to apex, the funicle is really present; and the ovipositor is inserted in the middle of the abdomen. Marginal vein as long as the submarginal, the stigmal with a short neck and a rounded knob. Mandibles tridentate. Male the same, except the shape of the abdomen and the 5-jointed antenna?. A short, distinct postmarginal vein. 1. Pseudobrachysticha semiaurea, new species. Female. — Length, 0.60 mm. Bright golden yellow, the abdomen black ,(the incisions of the segments sometimes showing through as yellow cross-stripes), the venation dusky black, the fore wing smoky from base to slightly beyond the apex of the venation, but subhyaline at base to the break of the submarginal vein and along under the marginal vein, the infuscation accented across froni base of the marginal vein and less so across from the apex of the stigmal (thus more or less bifasciate). Caudal wings slightly dusky to some little distance beyond the venation. Two to four isolated cilia on the fore wing in a line longitudinally between apex of stigmal vein and apex of the wing. Marginal cilia at apex of the fore wing about between a fourth and a third of the greatest wing width, distinctly shorter the caudal marginal cilia of the caudal wing. The latter rather broad, but distinctly narrower than the length of its marginal July, 191.5
