Mr. A. Hempel on Brazilian Coccide. 15 
This hole is from 1 to 1°5 millim. 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 fine white thread 
protrudes from it. Length 9 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 waxis brittle. The diameter 
of the cavity is about 5 millim. The female, removed from 
the test, is flat, nearly elliptical in shape, with the abdomen 
slightly attenuated posteriorly. It attains a length of 11 
millim., and a width of 6°5 millim. Colour yellow, with a 
pinkish tint; derm very soft, except 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 ina 
solution of KOH it colours the liquid a deep purple, almost 
black. ‘The derm becomes soft and colourless, except in the 
cephalic region. 
Antenne 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: (1) 178, 
(2) 110, (8) 110, (4) 110, (5) 110, (6) 110, (7) 89, (8) 141. 
Approximate formula: 18 (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 antenne. 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, 
Hab. On the bark of the ingé tree (nga sp ), growing 
along the banks of the Rio Mogy-guassti, 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 
sp.).
