Doimded ot' wax it is move or less elliptical, of a bright reJ 

 colour, like sealing-wax, and 9 uiillim. long, 6"5 niillirn. wide, 

 and 5oO millim. high. Tlie caudal horn is black, thick, and 

 conical, with the tip slightly elevated, 225 millim. long and 

 2 millim. wide at tlis base. Around the lateral border there 

 is a slight flange, which is excavated at the stigmatal areas 

 and posterior end, thus making it five-lobed. There are six 

 humps or tubercles present ; these are very sharp and are 

 situated one on the dorsum, one on the anterior end, and two 

 lateral on each side. The derm is dotted with minute pits, 

 is moderately shiny and soft, being chitinized only about the 

 caudal horn and stigmatal areas. Boiled in a solution of 

 KOH it colours the liquid red. The derm becomes soft and 

 transparent. 



The anteniise are 8-jointed ; joints 2 and 5 each bear two 

 very long hairs, joints 3 and 4 bear no hairs. Average length 

 •.')00 millim. Approximate formula : 5 3 (1 2) 8 4 (6 7) or 

 (.5 3) (1 2) 8 4(6 7). Length of joints : (1) 6Q, (2) 66, 

 (3) 84-88, (4) 40-44, (5) 84-1)3, (6) 31-40, (7) 31-40, 

 (8)44-48. Legs ordinary; trochanter long ; coxa with two 

 long subteiminal hairs. Length of joints of first pair of 

 legs : coxa 164, trochanter and femur 280, tibia 182, tarsus 106, 

 claw 22, digitules of claw 44. Tarsal digitules long, slender, 

 with expanded ends, reaching to the tips of the digitules of 

 claw, the latter being large, with the ends rounded and widely 

 expanded. Rostrum well-developed, placed behind tiie inser- 

 tion of the first pair of legs. Mentum with eight hairs near 

 the tip. Anal ring apparently with six large hairs. Anal 

 plates with three hairs near the posterior end. Around the 

 margin there is a single row of small hairs, each arising from 

 a tubercle. The stigmatal areas are each characterized by 

 seventy to eighty-five short bullet- shaped spines of different 

 sizes and over a hundred small round spinnerets. The derm 

 on the dorsal surface is thickly studded with short spine-like 

 hairs and small spinnerets. 



Male scale white, small, elliptical, with seven marginal 

 and two dorsal tufts of white wax. The marginal tufts are 

 arranged in a row of three on each side and one on the 

 anterior end. The posterior end bears a few white filaments. 

 Denuded of the tufts the scale is flat and very thin. Length 

 1"5 millim. ; width 80 millim. The male scales are usually 

 phiced close together on the underside of the leaves.
