‘089 millim. Rostrum and mentum ordinary. Rostral loop 
short. Legs wanting. ‘The external openings of the large 
pair of spiracles are surrounded by about sixty round spin- 
nerets. ‘he small spiracles are close together and have five 
or six spinnerets at the external opening. The four dorsal 
tubercles between the caudal ring and dorsal horn are small, 
each one bearing about forty spinnerets. Dorsal horn 
straight and sharp, ‘151 millim. long. Anal ring with ten 
large hairs, which do not protrude far beyond the caudal 
ring. The chitinous caudal ring ends in ten plates and bears 
many minute tubercles and several small spines at the base. 
The chitinous plates are short, narrow at the base, with the 
ends expanded and serrated. On the ventral surface, near 
the antenne and spiracles, are four groups of about sixteen 
elongate glands each. Scattered over the body are six or 
more areas in which the derm is partly chitinized and bears 
minute hairs and glands. 
Larve elliptical, as in ZT. eydonte. Length *450 millim. 
Hab. Sio Paulo. Clustered on the branches of cultivated

large, placed just behind the antenne. Rostral loop short. 
First pair of legs inserted very close to the rostrum. The 
large stigmata have each about 140 to 150 spinnerets around 
the external orifice, while the small ones have each 10 to 12 
spinnerets around the external orifice. Dorsal horn straight 
and blunt, about *173 millim. long. Lac-glands large, with
