as follows: i, 24-20-20; 2, 24-23-24; 3, 32-24-20; 4, 20-16-12; 



5, 24-16-16 ; 6, 44-36-32. The following formula have been observed : 



6, 3' (i' 2, 5,) 4,-6, 3, (i, 2,) (4, 5)-6, 3, 5, (i, 2, 4,)-6, 2, (i, 3,) 5, 4. 



Legs short and stout, tibia and tarsus subequal. Trochanter with a 

 slender spine, tibia with two spines, which extend half the length of tarsus. 

 Claw long and slender, digitules long, fine-knobbed hairs, reaching beyond 

 claw. Anal opening very small, hairless. There are several small spines 

 near opening. Margin beset with small spines at intervals of about 60 /x. 

 Caudal end of body shows many circular spinnerets and numerous fine 

 spines. 



Young larva light yellow, very active. Antennae 6 jointed. Joint 6 

 longest, then 3 ; joint i and 2 subequal ; joint 4 and 5 subequaL 

 Joint 6 with several stout hairs at end. Legs short and stout. Tarsus a 

 trifle longer than tibia. Femur + trochanter almost twice as long as 

 tarsus. Numerous stout hairs on each segment. Caudal setae very stout 

 and 160 fx long. There are several stout hairs between caudal setae. 



Habitat. — Under the dry bark and in crevices on the trunk of 

 Ciipressiis macrocarpa at Niles, Alameda Co., San Jose, Santa Clara Co., 

 Feb., 1903, and at Belvedere, Marin Co., California, 1908. 



Ceroputo Koebelei, n. sp. 



Adult female thickly covered with white secretion. The specimens 

 were received alive in rather bad condition, but after feeding and resting 

 the insects reconstructed a large cottony sac, almost like a large Pulvinaria^ 

 in which eggs were laid. One individual measured, with sac, 10 mm. 

 long and 4 mm. broad. Adult female is about 4 mm. long by about 25^ 

 broad at posterior end, narrowing cephalad a little. Body not very 

 convex, dorsum quite rugose, segmentation distinct, posterior margin 

 with deep cleft. After boiling in K. O. H. , the derm becomes almost 

 colourless except the area surrounding the marginal spines, legs, antennte 

 and mouthparts, which remain a dark brown. Antennae 9 jointed, each 

 joint with several long, fine hairs, joint 9 with several stout hairs near 

 apex. Joint 3 longest, about twice as long as 2, joints 4 and 5 subequaU 

 and joints 7 and 8 subequal. Measurements in micro-millimeters are as 

 follows : 1-40, 2-40, 3-75, 4-55, 5-54, 6-48, 7-38, 8-35, 9-47^ 

 Formula approximately 3-4-5-6-9-(i-2) 7-8; or 3-(4-5) 6-9 (1-2) 

 (7-8). Legs long and stout and quite hairy. Trochanter -t- femur very 

 little longer than tibia. Tarsus less than Yz of tibia, claw very strong, 

 with well developed tooth, digitules not reaching to end. Spine on 

 trochanter about as long as the outer curved margin of it.
