woolly secretion, very sticky, adhering to everything it 

 touches. Denuded of wax orange-yellow in colour; legs and 

 antennae dark brown. Body ovate, wider posteriorly than 

 anteriorly. The dorsum has two concentric rings of pits or 

 glands extending around it, dividing it into three areas. The 

 abdomen is transversely furrowed. 



Length 7"50 millim. ; width 5 millim. ; height 3 millim. 



Boiled in a solution of KOH it gives the solution a yellow 

 muddy appearance. The derm is thin and transparent. 



Antenna? variable, of 10 or 11 joints ; 11, however, seems 

 to be the typical number of joints, of which the last is the 

 longest. Joints 1-10 each bear a whorl of 7-9 hairs ; joint 

 11 has a brush of many hairs. Length about 1'10 millim. 



Approximate formula : 11 2 1 3 (7 3 9) 10 6 (4 5). 



Length of joints: (1) 110, (2) 123, (3) 97, (4) 66, (5) 66, 

 (6) 75, (7) 93, (8) 93, (9) 93, (10) 84,(11) 173. 



Legs long and hairy. Length of joints of first pair of 

 legs: coxa 191, trochanter and femur 594, tibia 604, tarsus 

 252, claw 66. Tarsal digitules wanting. Digitules of claw 

 short, hair-like. Eyes close to the base of the antennae, 

 small, conical, dark brown. Rostrum la 1 ^o, situated between 

 the first pair of legs. Rostral loop extending to the second 

 pair of legs. Mentum with about 20 hairs. The dorsal and 

 ventral surface of the body is crowded with hairs and large 

 round glands ; the hairs on the ventral surface, however, are 

 smaller than those on the dorsal surface. 



Larva (just hatched). — Orange-red, elliptical, "812 millim. 

 long and *400 millim. wide. A very little white secretion on 

 the back. Antennas about "555 millim. long ; of 6 joints, 

 the terminal joint longest and club-shaped. Length of joints : 

 (1) 57, (2) 70, (3) 79, (4) 79, (5) 79, (6) 191. All the joints 

 bear hairs ; joint 6 bears six very long hairs and many shorter 

 ones ; joint 5 bears also one very long hair. Eyes small, 

 conical, dark brown. The six central caudal bristles are 

 very long, attaining a length of 1*46 millim. Besides these 

 there are six shorter bristles on each side, but these are 

 scarcely one fifth as long as the others. The margin of the 

 body and the derm also bears numerous hairs, none of them 

 very long. Many round glands are also present in the derm. 

 The legs are long and thin, witli many hairs. Length of 

 joints of first pair of legs : coxa 79, trochanter and femur 

 222, tibia 244, tarsus 164, claw 40. Digitules of claw long, 

 slender, with slightly expanded ends. Tarsal digitules 

 wanting. Claw slightly notched. Rostral loop short, ex- 

 tending a little beyond the third pair of legs.
