agree in having a narrow fringe of white secretion around the 
ventral margin. It leaves an oval patch of white wax behind 
when removed from the bark. Length 8 millim., width 7:25 
millim., height 1°50 millim. Anal cleft 2°75 millim. long, 
sides contiguous. Boiled in a solution of KOE it stains the 
liquid dark red. The derm remains thick and brown, the 
colour being differentiated into a series of light and dark 
brown concentric rings. ‘The marginal ring is light brown 
and narrow ; within this there is a narrow dark brown ring, 
then a wide light brown ring, then a narrow darker ring, then 
a light ring of the same width, and, finally, a dark brown oval 
central spot. The entire derm is crowded with large irregular 
glands, with the opening near one side. Three or four rows 
of marginal glands are smaller than the others. 
‘The antenne: are small and variable, of six joints. Joint 3 
is the longest and sometimes has a false joint. All the 
segments bear hairs. Length about *258 millim. Approxi- 
mate formula: 3 1 (2 6) (4 5) or 316 (2 4) 5. Length of 
of joints: (1).86, (2) 31,. (6) 106, (4) 27, (5)-25, (6) oh 
Legs short. ‘The coxa bears two and the trochanter bears 
one long hair. Length of joints of first pair of legs: coxa 49, 
trochanter and femur 124, tibia 67, tarsus and claw 84. 
Claw small, greatly curved; digitules unequal in size, with 
expanded ends. Digitules of tarsus long and slender, with 
ends slightly expanded. Second and third pair of legs close 
together. Rostrum small, placed near the insertion of the 
second pair of legs. Anal plates small, the outer angle 
rounded, and the two lateral sides equal in length. The 
stiginata are large and disk-shaped, with about a dozen small 
round spinnerets about the external orifice. Around the 
lateral margin there is a single row of small, sharp, conical 
hairs, placed about *i20 millim. apart. 
The eggs are elliptical, smooth, dull, orange-yellow in 
colour.

‘Lhis species evidently secretes a great deal of honey-dew, 
for it is frequently covered with a black fungus, and is also 
attended by an ant, Camponotus sp., that often builds a 
covering of earth or grass over it. This covering may 
serve as a protection against rain and sun and parasitic 
Hymenoptera.
