TWO NEW MEALY-BUGS FROM NEW MEXICO. 



BY T. D. A. COCKER ELL. 



Phenacoccas cevallice, n. sp. 



°. . Oval, 4 to 5 mm. long, pale olive green, but covered with white 

 secretion, with lateral tassels and thick caudal tassels ; placed in alcohol, 

 they stain the liquid pale green ; alcoholic specimens appear strongly 

 segmented, with two longitudinal blackish bands, best marked in rather 

 immature specimens. Eyes prominent ; skin with many small circular 

 glands ; the lateral patches consist of about twelve glands each, but 

 are without spines ; a few rather large bristles scattered about the body ; 

 legs and antenna? reddish-yellow ; denticle on inner side of claw rudimen- 

 tary, just visible ; antenna 3 g-jointed, the club 2-jointed. Measurements 

 of antennae and legs in fi : Anterior legs, femur and trochanter 470, 

 tibia 330, tarsus 130 ; hind legs, femur and trochanter 540, tibia 440, 

 tarsus T35. Antennal joints: (1.) 45-60, (2.) 108-nr, (3.) 63-66, (4.) 

 60, (5.) 72-75, (6.) 51, (7.) 51, (8.) 45, (9 ) 67. 



Newly-hatched larva very pale lemon-yellow, about twice as long as 

 broad ; eyes conspicuous. 



Hab. — In enormous numbers on Cevallia sinuata, near Lea Lake, 

 east of Roswell, N. ML, Aug. 21, 1902. Much preyed upon by 

 Coccinellids ( Hyperaspis) and Chalcidids. It is allied to P. solenopsis, 

 but from its large size and abundant secretion, it looks like a Ceroputo. 

 Professor Tinsley was with me when the species was discovered, and 

 we both thought it a relative of C. yuccce. 

 Psaidococcics Neomexicanus (Tinsley), var. alkalinus, n. var. 



$. About 2J-2 mm. long and 1^ broad, covered with mealy-white 

 secretion, with short, thick, cottony caudal tassels, and lateral tassels 

 posteriorly; secreting a thin but dense white sac, which covers all but the 

 hind end of the insect. These sacs are often irregularly stained with 

 bright yellow. 9 (after boiling in water and mounting in oil of cloves) 

 bright orange ; antennae and legs light yellowish-brown ; no produced 

 caudal tubercles ; labium 120 \>. long and about 78 broad; eyes prominent; 

 caudal bristles about 75 /x long; bristles of anal ring about 66//.; legs 

 quite stout, breadth of anterior tibia 36 /i ; ciaw with no denticle on inner 

 side; claw digitules very slender ; no distinctly knobbed tarsal digitules ; 

 antennas 8-jointed. Measurements of legs and antennae in /< : Anterior 

 legs, femur and trochanter 210, tibia 135, tarsus 69 ; hind legs, femur and 

 trochanter 231, tibia 174, tarsus 78. Antennal segments: (r.) 45-54, 

 (2.) 48-54, (3-) 36-4L (4-) 24-30, (5-) 2 4, (6.) 22-24, (7.) 24-25,(8.) 66-78.
