Megalecanium testudinis n. sp. 
The adult female has the body hemispherical 
and irregularly circular in outline, with the dorsal 
surface very shiny. The general color of the dor- 
sum is light green, with dark brown and yellow 
areas, arranged in five longitudinal rows, of which 
one is median and two lateral on each side; the 
brown and yellow areas being arranged alternately 
in these rows. The lateral margins are depressed, 
and also have some dark brown areas. The pos- 
terior margin is incised. The anal fissure is about 
1.200 mm. long with the margins contiguous. The 
ventral surface of the body is pink in color. Be- 
neath the individuals, there is secreted a mass of 
white, woolly wax, in which the eggs, light yellow 
in color, are placed The younger individuals have 
the body flatter. The largest individuals have the 
body 13 mm. long, 11.500 mm. wide, and 6.600 
mm, high. 
Boiled in a solution of KOH, the liquid he- 
comes colored dark orange, and the derm becomes 
translucent, but retains its rigidity and consistency. 
The antennae are long and slender, from 0.653 mm. 
to 0.670 mm. long, composed of 8 joints, which 
have th? following lengths: (1), 93; (2), 81-93; 
(9), 1085 4 49,:1085 (5) 03-1006 (6-) “025000

the following being the lengths of the joints of the 
first pair: coxa, 139; femur and trochanter, 325; 
tibia, 232; tarsus, 162; claw, 31. The tarsal digi- 
tules are long and slender, with the extremity but 
slightly dilated, and are 19 microns in length ; while 
those of the claw are wider with the extremities 
more dilated, and are 38 microns long. The later- 
al margin is but slightly incised at the stigmal 
areas, which are caracterizised by three thick 
spines, two of which are straight and 31 microns in 
length, while the cther js curved, and is 62 microns 
in length. Around the margin of the body there
