122 Mr. A. Hempel on Brazilian Coccide. 
different individuals usually fuses, but does not form large 
masses. The outside is dull and smooth, with many filaments 
of white secretion scattered over it. The lac is a red-orange 
colour and brittle only in very old specimens. 
Size of largest individuals:—Length 5 millim.; width 
4°25 millim. ; height 2°5 millim. 
Adult female denuded of wax, subcircular, convex, with a 
tendency to form six lobes. Boiled in a solution of KOH it 
colours the liquid a deep red. The lac- glands are large, club- 
shaped, and do not have the spines at the external opening as 
in LT. cydonie, ‘The antenne are apparently of four segments ; 
they are ‘084 millim. long, club-shaped, and the terminal 
joint bears two short hairs. Rostrum and mentum small. 
Rostral loop short. Legs wanting, Anal ring with ten 
large blunt hairs, which protrude but little beyond the chiti- 
nous ring. The chitinous plates on the caudal ring are ten in 
number, with nearly parallel sides, and the ends coarsely 
serrated. ‘The dorsal horn is ‘089 millim. long, blunt, and 
slightly curved at the base. The large spiracles are close to 
the lac-glands and have many spinnerets around the external 
orifice. ‘The small spiracles are situated near the rostrum 
and have twelve to fifteen spinnerets about the external 
orifice. The four tubercles between the caudal ring and dorsal 
horn are well developed and bear many round spinnerets. 
The surface of the body bears many small tubercles, each 
ending ina hair. The four groups of elongate glands found 
on the ventral surface of T. cydonte were not seen in this 
species. 
Length 8 millim. ; width 3 millim.; height 2 millim. 
Larva as in T. cydonie. Length ‘500 millim. ‘The ros- 
trum is very large and the rostral filaments are longer than in 
the preceding species. 
Hab. Cachoeira and Santa Barbara, State of 8. Paulo. 
Clustered in great numbers on the branches of a species of 
Croton and on other plants. 
Tachardia parva, Hempel. 
‘The younger females have a test of brown lac, elongate, 
with a tubercle in the middle of the dorsum and _ three 
processes on the lateral margin on each side. In the older 
specimens the test is globular and of an orange-brown colour. 
Specimens varying from 2-2°75 millim. long and 125-2 
millim. high. 
The female, denuded of wax, has three conspicuous lobes 
on each side. Length about 1°25 millim.; width *75 millim.
