white, sometimes showing a creamy tinge, distal end curved 

 up. Beneath it is convex and slightly striated longitudinally. 

 Dorsum and side longitudinally fluted, with 14 or 15 longi- 

 tudinal furrows. In the largest individual examined the 

 anal tuft was 20*5 millim. long. The caudal and cephalic 

 tufts are usually fluted with four longitudinal ribs. The 

 ovisac has one or two longitudinal slits on the medial dorsal 

 line, through which the young escape. Forty-four eggs 

 were found in one sac. 



Antenna? usually 11-jointed : joint 5 is the shortest, and 

 sometimes unites with joint 4, making the antenna? only 

 10-jointed ; joints 2, 4, 6-10 are subequal in length ; joint 

 11 equals or slightly exceeds joints 9 and 10 in length. 

 Length of antenna? variable ; the longest observed was 

 1*1 millim. long. Joints 1-10 each bear a whorl of about 6 

 hairs, while joint 11 has a terminal band of 15 or 16 hairs. 



Legs ordinary ; tarsus curved near the distal end ; digitules 

 absent. Digitules of claw fine, hair-like, short. 



Rostrum large, situated just between the first pair of legs. 

 Mentum with about 28 hairs. Rostral loop reaching beyond 

 the insertion of the second pair of legs. Numerous hairs are 

 scattered over both surfaces and around the margin ; while 

 the body is terminated by two terminal tufts of 5 long hairs. 

 The entire dorsal surface is crowded with glands ; these are 

 round and appear to be composed of 6 to 9 parts placed in a 

 circle, with a long glassy filament in the centre. 



Length of insect and ovisac, excluding the tufts, 105 

 millim. 



Larva (just hatched). — Elliptical, deep red with a pinkish 

 tinge. On the dorsum there are four tufts of yellowish wax, 

 forming a diamond-shaped patch, with the long diameter 

 placed cephalo-caudad. Antenna? 6-jointed : joints 2-5 sub- 

 cylindrical and subequal in length, "066 millim. long ; joint 1 

 convex on the inner side; joint 6 club-shaped, *164 millim. 

 long; joints 2-5 have each one long slender hair and several 

 shorter ones ; joint 6 with 6 very long hairs (longer than the 

 antenna?), "64 millim. long, and about 12 short ones. 



The dorsum bears many slender hairs, placed in about ten 

 irregular longitudinal rows. On the head there are four 

 bristles between the eyes ; the two middle ones are very long, 

 reaching nearly to the tip of the antenna?. There are 6 anal 

 bristles about 1*35 millim. long, equalling nearly twice the 

 length of the body. There are also 6 shorter bristles on each 

 side of the abdomen not one third the length of the anal 

 bristles. The lateral margin of thorax and head also bears 

 some short bristles. Dorsum with many round secretory
