The dorsum has six pits arranged in two longitudinal parallel 
rows. The two anterior pits are shallow, but the other four 
are very deep. Between these pits the dorsum stands out in 
thick transverse ridges. Derm thick, not shiny, with nume- 
rous oval glands. Length 8 millim., width 6 millim., height 
4 millim. Anal cleft 1-60 millim. long, sides contiguous. 
Boiled ina solution of KOH it colours the liquid dark brown. 
After boiling the derm becomes semitransparent, but remains 
brown, thick, and hard. 
Antenne of six joints, of which the third is the longest, 
Average length of antenne: *380 millim. Approximate “fore 
mula: 3 1 (2 4 5) 6 or 31 (56) 2 4. aie of joints: 
(1) 53, (2) 40-44, (3) 156-173, (4) 30-44, (5) (6) 40-14. 
All the joints bear hairs. Legs Saree a the joints 
bearing hairs near the distal end. Claw short, sharp, and 
much curved at tip. Digitules of claw wide, with widely 
expanded ends. Tarsal digitules long, slender, with ends 
expanded, reaching beyond the digitules of claw. Length 
of joints of last pair of legs: coxa 111, femur and trochanter 
209, tibia 133, tarsus and claw 124. First and second pair 
of legs widely ‘separated, second and third pair of legs close 
together. Rostrum small, situated between the first pair of 
legs. Rostral loop short. Stigmata large, with peculiar 
pouch-shaped glands around the e external orifice. These glands 
are also present near the lateral margin on the ventral surface, 
The anal ring bears ten hairs. Anal plates small, each one 
hemispherical in form, ‘The dorsal derm_is composed of 
large irregular glands, with oval centres, and a hyaline spot 
within the oval. Over these glands there is a very thin 
covering, apparently composed of minute square pieces of 
material. Around the lateral margin there is a scant row of 
short thick hairs.

Lecanium discoides, Hempel. 
Adult female light reddish brown, subcireular, flat, with a 
slight notch in the posterior margin. ‘The derm is hard, 
reticulated, the reticulations being orange-red in colour, 
while the partitions are thick and brown. The surface is 
dull, shiny, shghtly roughened by very shallow radial furrows. 
Many specimens also show a faint median longitudinal ridge. 
The younger specimens are usually ornamented with smail 
patches of brown wax, especially on the margin, which con- 
tains from sixteen to twenty triangular pieces. In the older 
specimens this wax is usually rubbed off. All the specimens
