lcerya taunayt n. sp. 
The young and immature female has an oval 
body, dark brown in color on the upper surface 
and red on the lower surface. The antennae and 
legs are also red. Around the margin of the' body 
there is a row of small, white tufts, and on the 
dorsal surface there is one median row and three 
other longitudinal rows, between the median and 
the margin, of small, white tufts, more or less cir- 
cular in outline. The largest specimens had a length 
of 9 mm., a width of 5.500 mm., and a height of 
4 mm., being higher on the thorax than on the 
abdomen. 
Boiled in a solution of KOH, the derm be- 
comes soft and transparent,eand the liquid becomes 
turbid, and has a dark yellow color when decanted. 
The antennæ, in this stage, have only 8 joints, and 
are from 0.883 mm. to 0.970 mm. long. The dif- 
ferent joints have the following lengths: (1), 216; 
(2), 108; (3) 124; (4), 62; (5), 84; (6), 
84; (7), 77; (8), 216. The approximate for- 
mula às: (8,1 ),3, 254005, 6), Te) he) tems 
are short and strong, the following being the lengths 
of the first pair: coxa, 310; femur and trochanter, 
883; tibia, 402; tarsus, 294; claw, 124. The 
digitules are short and filiform. The tibia has about 
16 short, thick spines on the posterior margin, and 
the tarsus has about 4 of these spines. The eyes 
were not observed. 
The entire surface of the derm, both the dor 
sal and the ventral surfaces, is covered with strong 
spines, generally curved, although there are some 
that are straight. ‘he majority of these spines 
are about 90 microns long, but there are some
