apex, ending with stout spine. Formula : 6, i, (2, 5) 3, 4. Measure- 

 ments in /x are 1-40 ; 2-28 ; 3-24 ; 4-20 ; 5-28 ; 6-68. Legs long and 

 stout. Coxa almost twice as broad as long, tibia shorter than tarsus, claw 

 slender and slightly curved. Digitules fine hairs. Trochanter with long 

 hair and tibia with two stout spines near distal end. 



Caudal tubercles quite prominent, with long setae. Anal ring with 

 the usual hairs and a number of shorter spines. Adult female in sac about 



5 mm. long and 2 mm. broad, tapering almost pyriform, snow-white of 

 dense cotton. Dead female removed from sac reddish brown, segmenta- 

 tion distinct, about 4^ mm. long, 2 mm. broad, convex above. Body 

 almost void of powdery secretion and somewhat shiny. After gestation, 

 body shrivels and sac becomes filled with loose cotton, in which the eggs 

 are laid. When boiling in K. O. H. body turns cardinal, derm becomes 

 colourless, with numerous small, round glands and fine spines. Antennae 



6 jointed, joint i much broader than long, joint 6 longest, then i, then 

 2 and 3, which are subequal, joint 4 being the shortest. Formula : 6, i, 

 (2, 3) 5, 4. Measurements in /x are as follows : 1-64 ; 2-40 ; 3-40 ; 4-24 ; 

 5~35 j 6-68. Some specimens have joint 6 subequal with joint i and 

 joint 5 subequal with 2 and 3, so that the following formula is noticed : 

 (i, 6) (2, 3, 5) 4. Each joint has several hairs, and joint 6 has a whorl of 

 hairs at apex. 



Legs short and stout, coxa broader than long, trochanter with spine 

 about as long as tarsus. Tarsus quite hairy, claw long and sharply 

 curved, digitules fine hairs. Anal ring about 80 /x in diameter, quite pro- 

 nounced, with 6 long, stout hairs about 160 /x long. Caudal tubercles 

 not conspicuous, with long setse about 200 /x and with numerous spines 

 and round glands. 



Habitat. — On grass roots (Distichlis sp. ?) in salt marsh, Alameda 

 shore, Alameda, California. July 25, 1906. 



Sphcerococcus cupressi^ n. sp. 



Adult female imbedded in a pit between the dry and growing bark, 

 lying on and covered with cottony secretion, hiding the entire insect. 

 Body about i^ mm. long and about i mm. broad, quite convex, resem- 

 bling a Diaspine in outline. Colour pale pink, more or less transparent. 

 When placed in boiling K. O. H., turns dark red, and after boiling derm 

 becomes transparent. 



Antennae 6 jointed, short and stout. Joint 6 with numerous stout 

 hairs. Some of the measurements in micro-millimeters of the joints are
