The dorsum lias six i)it.s arraiip^od in two lon;^itudinal parallel 

 rows. Tlu> two anterior pits are shallow, hut the other lour 

 are very deep. Between these pits the dorsum stamls out in 

 thiek transverse ridj;es. Derm thick, not shiny, with nume- 

 rous oval glands. Length 8 millim., width 6 millim., height 

 4 millim. Anal cleft \'G0 millim. long, sides contiguous. 

 Boiled in a solution of KOIi it colours the liquid dark brown. 

 After boiling the derm becomes semitransparent, but remains 

 lirown, thick, and hard. 



Antennie of six joints, of which the third is the longest. 

 Average length of antenna? '380 millim. Apjiroximate forr 

 mula : 3 1 (2 4 5) 6 or 3 1 (5 6) 2 4. Length of joints: 

 (1) 5.5, (2) 40-44, (3) L56-173, (4) 30-44, (5) 44, (G) 40-14. 

 All the joints bear hairs. Legs ordinary, all 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, ilostrum small, situated between the first pair of 

 legs. Rostral loop short. Stigmata large, with peculiar 

 pouch-shaped glands around the external orifice. These glands 

 are also present near the lateral margin on the ventral surface. 

 Ihe 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.

Lecaninm discoides, Hempel. 



Adult female light reddish brown, subcircular, 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, slightly roughened by very shallow radial furrows, 

 Many specimens also show a faint median longitudinal ridge. 

 The }ounger specimens are usually ornamented with small 

 patches of brown wax, especially on the margin, which con- 

 tains from sixteen to twenty triangular pieces. Li the older 

 specimens this wax is usually rubbed off. All the specimens
