brown, except a narrow marginal stripe of dirty white. Caudal cleft 

 about I mm. long. Boiled in a solution of KOH, it colours the liquid a 

 dark amber. Antennte 8-jointed, .48 mm. long. Joint 3 the longest ; 

 joints 4 and 5 considerably shorter; joints i and 2 about half as long 

 as 3, and the other joints shorter. Formula 3(45)12867. All joints 

 except joint 3 bear hairs. Legs ordinary, coxa with several hairs, and 

 one short, sharp spine near the proximal end ; trochanter with one very 

 long apical hair and two short ones ; femur stout ; tibia not quite so long 

 as femur ; tarsus half as long as femur ; claw long, stout, curved. Tarsal 

 digitules very long, slender, with knobbed ends ; digitules of claw not 

 twice the length of claw, stout with expanded ends. Mentum situated 

 between the fore legs ; rostral loop long, reaching half way to the inser- 

 tion of the last pair of legs. Anal ring with ten long hairs. There is 

 a smgle marginal row of rather long, slender hairs. Stigmatal 

 spines three, one long, slightly curved, two short and stout. A group of 

 about 50 small round spinnerets is situated around each stigmatal area. 

 Numerous filiform glands are scattered over the ventral surface. Anal 

 plates small, both lateral sides being of equal lengtii. Height, 2 mm.; 

 width, 4.50 mm.; length, 6 mm. 



Ovisac cone-shaped, longitudinally fluted with about 16 ridges. The 

 anterior part is secreted faster than the posterior part, so that the anterior 

 edge becomes convex, and when it is completed the insect rests upon it 

 in an oblique position. The ridges are closer together on the posterior 

 edge than on the anterior. The colour is white with a faint creamy 

 tinge. Length, 5 mm.; width, 3.75 mm.; height, 7 mm. 



Larva, just hatched. — Light brown, elliptical. Margin of body 

 finely serrated ; a short hair is situated on each side of the body at each 

 abdominal segment ; eight short hairs on the anterior margin between 

 the antenna?. The body is terminated posteriorly by two long setje 

 and several small hairs. The prothorax and mesothorax each bear a 

 long, straight spine, on the margin, on each side of the body. Antennae 

 long, six-jointed, three the longest, and six the next ; the other joints sub- 

 equal in length. Legs ordinary, tarsal digitules long, slender, with slightly 

 expanded ends ; one of them as long as tarsus. Claw long, curved ; 

 digitules of claw slender, with expanded ends. Rostral loop long, 

 reaching to the anal cleft.
