on the (lorsmn and a lighter ring around the margin. 

 Slightly asyni metrical. 



Diameter o inilliin. ; anal cleft 1%J5 milliin. long, 

 lioiled in a solution of KOll the dorsal derm remains 

 thick and of a light brown colour. It is composed of about 

 thirty-lour irregular j)l;ites, consi-^ting of a metlian dorsal area 

 of twelve plates, around which the others are arranged in a 

 single row, like the |)lates on the back of a turtle. The 

 spaces between the |)late3 are narrow and scinifransparent. 

 There is also a median longitudinal row of Hfty to sixty small 

 round pores. 



Antenna? variable, of .six joints, about "200 millim. long. 

 Ajiproximate fnrmula : 8(5 (12) (4 5). Lengtii of sei^ments : 

 (1) 31, (2) 31, (3) 71, (-4) 1^, (5) 18, («) 38. Joint 3. some- 

 times has a false joint. All joints bear hairs. First pair of 

 legs inserted near the antenuEe. Second and third pair of 

 legs close together, but widely separated from the first pair. 

 Legs very short and somewhat detormed. The division be- 

 tween the tareus and tibia is usually obliterated, and this 

 segment is usually curved. Length of joints of Hist pair of 

 legs : coxa 44, femur with trochanter 71, tibia, tarsus, and 

 claw 88. All the digitules have expanded ends and extend 

 beyond the tip of claw, those of the claw being unequal in 

 size. Kostrum small, situated just caudad of the insertion of 

 the first pair of legs, llostral loop short, extending halfway 

 to the second pair of 1 gs. The first pair of spiraeles aie 

 situated outside of the first ])air of legs, the second pair outside 

 of the second pair of legs, but closer to tiiem. Anal plates 

 small, with the outer angle but slightly rounded and the 

 aiitero-lateral sides longer than the postero-lateral. Anal ring 

 apparently with ten hairs. Around the lateral margin of the 

 body there is a row of fine hairs placed widely apait. The 

 stigmatal areas are characterized by a group of three club- 

 shaped spines — two short and one long — and four small hairs. 

 A few short hairs are scattered over the dorsal surface. 



}t\n\e scale oval, rather flat, composed of very thin, white, 

 glassy wax. The scale consists of one narrow dorsal plate 

 and seven lateral plates. Length 2 millim.; width T5 

 millim. 



Larva (newly hatched). — Elliptical, light yellow in colour, 

 with small irregular dark brown eyes. Length •562 njillim. 

 The body ends in two plates, each terminated by a long con- 

 spicuous seta. The lateral margin is finely serrated; the 

 abdomen beais several hairs on the margin, and each stigmatal 

 area is characterized by one large club-shaped spine and two 

 verv small ones. Antenna? ()-ji>inted, joints 3 and 6 longest
