PSYCHE. 



215 



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 fus- 

 cous : 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. 



Seven males, twelve females and the 

 gynandromorphic specimen.

 Wind River (IX. 2, 1895) Wyoming. 



This species seems to be allied to 

 scriata, Loew, of the Eastern States, 

 which also has ovate metatarsi in the 

 males. As I)r. Loew does not mention 

 the place of articulation of the second 

 joint, it may be presumed that it is ter- 

 minal to the metatarsus as in the other 

 forms of the genus. Moreover, the 

 middle tibiae of the male sciiafa are 

 provided with rather long pubescence, a 

 character not observable in Wheehri. 



A NEW COCCID ON ROOTS OF 

 RUBUS. 



BY T. D. A. COCKERELL. 



Phenacoccus rubivorus, n. sp. — $ — Hem- 

 ispherical, with the form of a half-pea, dis- 

 tinctly segmented, pale pinkish, thinlj' cov- 

 ered with white mealy seci-etion ; 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 approxi- 

 mately 92(35)6(471)8. The following meas- 

 urements are in ji; — 



Antennae segments ; (i.) 36, (2.) si, (3-) 

 48, (4.) 39, (5.) 45, (6.) 43, (7.) 39, (S.) 30, (9.) 

 69. Middle legs; femur -)- trochanter, 222 ; 

 tibia, 174; tarsus, 90 ; claw, 27. Of course 

 these measurements will vary, no two indi- 

 viduals being exactly alike. 



The females studied contained very well- 

 developed embryos.' These sliowed small 



spines, round glands, and a small patch of 

 spines on each lateral margin of each segment.

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 Tetruia rtibi de- 

 scribed by Lichtenstein, concerning which 

 see E/i/omoloo-is/^ 1900, p. S6.
