Edwallla., n. g. 

 Apparently related to Farmairia, Sign. ? . Scale waxy, hard, 

 brittle, cone-shaped with radial ridges and furrows. Antennae five- 

 jointed. Anal-plates curved ; the two together forming a ring. Each 

 plate is furnished with ten long hairs. Type, E. riigosa. 



Edwallia rugosa, n. sp. 

 J . — Scale white ; wax hard and brittle, cone-shaped, having the 

 appearance of a barnacle, and radially ridged or fluted like the shell of 

 Peden. The base is slightly oval in shape, being wider anteriorly than 

 posteriorly ; the anterior side is slightly convex, so that the top of the 

 scale is caudad of the middle. A number of fine concentric rings run 

 around the scale parallel to the base. The inside of the scale is shiny 

 and quite smooth. Adult 9 fills the entire scale. Derm smooth, lemon- 

 yellow in colour. Around the margin of the body there is a row of about 

 2IO small sharp conical spines, and near the margin on the dorsal surface 

 there is a double row of minute hairs. The stigmatal areas are charac- 

 terized by one large curved spine, with a round spot at the base ; and by 

 a group of from 13 to 19 small round glands. The caudal cleft is very 

 short, each lobe bears a hair longer than the marginal spines. Anal 

 orifice surrounded by a chitinous ring, within which is the anal ring 

 bearing six long hairs. Anal plates curved, irregular, triangular, the 

 dorsal side longer than the ventral side. Each plate bears 10 long hairs, 

 two of which are straight and spinelike ; the others are longer and more 

 flexible. Three are situated on the dorsal surface and 7 on the ventral. 

 The plates are so placed that they together form a second anal ring 

 with 20 hairs. Just in front of the anal ring there is a group of about 20 

 small round spinnerets. Antennte five-jointed, .12 mm. long. Joint 3 

 the longest ; joints i and 5 are about equal in length ; joint 4 is about 

 half the length of 3 ; and joint 2 is the shortest. Formula 31542, or 

 3(15)42. All the joints bear hairs; joint 3 bears two, one of which is 

 quite long; joint 5 has five hairs. Legs ordinary, coxa and trochanter 

 each with a subterminal hair. Femur wide, with a short sharp spine near 

 the distal end ; tibia about as long as femur, the distal end enlarged and 

 bearing one hair ; tarsus and claw not quite as long as tibia, two hairs on
