'i'liis hole is tVom 1 to 1*5 inilliin. in diameter. The inside 

 of the test is spherical, with two rows of small white spots 

 of secretion, corresponding to the stigmata of the abdomen. 

 Frequently a large part of the abdomen is protruded out 

 of the apical hole; but usually only a (ine white thread 

 protrudes from it. Length D millim., width 7-8 millim., 

 height 8*5 millim. The thickness of the wall of the test is 

 1*25 millim. to 2 millim. The wax is brittle. The diameter 

 of the cavity is about 5 millim. The female, removed from 

 the test, is ilat, nearly elliptical in shape, with the abdomen 

 slightly attenuated posteriorly. It attains a length of 11 

 iTiillim., and a width of 6"o millim. Colour yellow, with a 

 pinkish tint; derm very soft, exce|)t on the head, where there 

 IS an area of the derm chitinized, flat, and of a dark brown 

 colour. The abdomen is transversely wrinkled. Boiled in a 

 solution of KOII it colours the liquid a deep purple, almost 

 black. The derm becomes soft and colourless, except in the 

 cephalic region. 



Antennje variable, of seven or eight joints, although eight 

 is the typical number. Length about "950 millim., each joint 

 bears thirty or more hairs. Length of joints: (I) 178, 

 (2) 110, (3) 110, (4) 110, [')) 110, (6) no; (7) 89, (8) 141. 

 Approximate formula : 1 8 (2 3 4 5 6) 7. Legs long and 

 full of hairs. The coxa is nearly twice as wide as long ; the 

 trochanter bears about thirty round glands ; the tibia is 

 frequently bent back near the distal end, while the tarsus is 

 always curved. Length of joints of first pair of legs : coxa 

 187, trochanter and femur 812, tibia 687, tarsus 350, claw 

 97. Claw sharp, much curved, with two short hair-like 

 digitules. Tarsal digitules wanting. Rostrum ordinary, 

 situated close to the antennae. The abdomen bears eight pairs 

 of spiracles, each with a number of small pentagonal spinnerets 

 around the external opening. The thoracic region also bears 

 two pairs of stigmata; these are large, chitinized, with the 

 external orifices flask-shaped, and many small spinnerets 

 grouped about them. Anal ring hairless. The derm on the 

 posterior end of the body is thickly set with peculiar glands, 

 disk-shaped, and apparently three-celled. The remainder of 

 the derm bears numerous small hairs and glands. 



llah. On the bark oi the inga tree {Inc/a sp ), growing 

 along the banks of the llio Mogy-guassii, near Pirassununga, 

 State of Sao Paulo ; and from Joinville, State of Catharina. 

 The insects are usually crowded on the underside of the limbs 

 and branches, and are covered with a black fungus, and 

 accompanied by many individuals of an ant {Camponotus
