A New Species of Chrysopa From Texas

International Journal of hairs of the upper edge of the male fore tibiae are longer. The middle and hind coxae are black, the fore coxae more or less fuscous tarsi black, the remainder of the legs variable in color from fuscous to piceous. The front metatarsi of the male enlarged, ovoid, the distal third of the inner side is excised for the reception of the remainder of the tarsus, which thus is not attached at the tip of the metatarsus. The front tibiae of the males are somewhat thickened. Wings cinereous-hyaline, stigmal spot faintly brown, neuration normal. - A NEW COCCID ON ROOTS OF RUBUS. BY T. D. A. COCKERELL. Pkenacoccus rubivorus, n. sp.m --Hemispherical, with the form of a half-pea, distinctly segmented, pale pinkish, thinly covered with white mealy secretion; no cottony appendages. Boiled in liquor potassae, they stain the liquid amber yellow, and the skin becomes colorless. Anal ring with 6 hairs. Caudal tubercles very low and inconspicuous, with short bristles. Legs and antennae very pale brownish; claw with a small denticle on inner side; digitules slender, with small knobs. Antennae 9-jointed, formula approxi69. Middle legs; femur -- trochanter, 22 mately 92135)6(47)8. The following measurements are in : Antennae segments; (.) 36, (2.) .g, (3.) 48 (4") 39, (5.) 45, (6.) 43, (7.) 39, (8.) 3 (9.) tibia, 74; tarsus, 9 claw, 7. Of course these measurements will vary, no two individuals being exactly alike. The females studied contained very welldeveloped embryos. These showed small spines, round glands, and a small patch of spines on each lateral margin of each segment. /-lab. Beulah, New Mexico, about 8,000 ft. alt., end of March, x9ox, on roots of tguus str[ffosus Collected byWilmatte P. Cockerell. This interesting species does not have the superficial appearance of a Phenacoccus, though the antennae and legs are as in that genus. I suspect that when we know the male it will turn out to be congeneric with the little-known European Tetrura rubi described by Lichtenstein, concerning which see tnlomologist, I9OO, p. 86. A NEW SPECIES OF CHRYSOPA FROM TEXAS.* BY JESSE F. MCCLENDON. Chrysopabimaculata, sp. nov. Length to tip of wings I.5 mm-3.5 ram., Mar expanse 2 -25 ram. Mouth short, antenna slightly shorter (Contributions from the Zoological Laboratory of the University of Texas, No. 9.) rjun, ,9o, than the wing prothorax broader than long wings moderately narrow, anterior pair slightly pointed, posterior more acutely, in anterior wing divisory veinlet of third cubital areole exceeding the first cross-vein of the first radial sector.* Face stramineous, vertex green, gular region stramineous, segments of palpi black, ineous, darker towards apex, first article with a red longitudinal line above thorax green, paler beneath, prothorax with a luteo-rufous streak on each side from anterior to posterior margin; abdomen green; legs pale green, tarsi yellowish, ungues fuscous; wing veins green, in anterior wing all cross veins black or varied with black, in posterior wing costal their articulations colorless, antennae stram The position of this veinlet has been noted in descriptions of many species of Chrys@a, but examining number of specimens of Chrysapa e:rterna, found it to vary much to be of value in determining that species. Whether it varies in C. bimaculata, unable to decide account of the small number of specimens in my possession. cross-veins and a few others black, pterostigma light green. Coloration of alcoholic specimen: green faded to pale yellow, line on first article of antennae fuscous, streak on prothorax faded out, black retained. Four specimens from Laredo, Texas.
