small patches of wax, giving the insect a rough grey appear-. 
ance, like a scar or bud. ‘The cells or reticulations are 
small, red in colour, the partitions being thick and black. 
On the ventral surface the derm is chocolate-brown. The 
opening of the cavity containing the eggs is small, 1°75 
millim. wide, and nearly square. There is a narrow white 
fringe of secretion around the ventral margin. A white 
patch remains on the bark when the insect is removed, 
Length 5 millim.; width 4 millim.; height 1:25 millim. 
Anal cleft 1 20 milli, long, sides contiuous. Boiled in a 
solution of KOH it colours the liquid dark red. he dorsal 
derm remains thick and brown. The central portion is 
composed of large, irregular, oval glands, with a small sub- 
circular hyaline spot near one end, while near the margin 
there is a border composed of four or five rows of smaller 
subcircular glands. ‘The hyaline spots in these glands are 
apparently the openings, ‘The outer portion of the ventral 
derm is chitinized, forming a border about 1 millim. in 
width. 
Antenne slender, of seven joints. All the joints except 
joint 3 bear hairs s, joint 2 2 bearing one long one. Length of 
antenne about *40 millim. Approximate formula: 4 (1 2 
37) 56. ne of joints: (1) 44, (2) 44, (3) 44, C4) 93, 
(5) 86, (6) 31, (7) 44. Legs ie and thin, varying in 
length. ‘Tarsus and claw as long as the tibia, Average 
lenoth of joints of the first te of legs : coxa 93, trochanter 
with femur 164, tibia 102, tarsus and claw 102. The coxa 
bears a short spine on the proximal end; the coxa and tro- 
chanter each bear a long terminal hair on the distal end. 
Tarsal digitules very long and slender, with expanded ends 
(53 pu long). Digitules of claw large, unequal in size, with 
expanded ends. Rostrum small, stunted between fie inser- 
tion of the second pair of legs. Mentum monomerous, with 
bifid end, bearing eight hairs, Rostral loop short. Spiracles 
small. Around the lateral margin there is a row of short, 
sharp, thick spines, placed at intervals of about 111 yw apart. 
Anal plates small, with the outer angle rounded and the 
antero-lateral side longer than the postero-lateral. 
Hab. Ypirauga, State of S. Paulo. On branches of 
Zanthoaylum sp. Situated on the bark, where it resembles 
the leaf-scars and buds so closely as almost to escape notice. 
Lecanium infrequens, Hempel. 
Adult female large, dark brown, irregular in_ outline, 
dorsum convex, sometimes with small patches of white w ax.
