Mr. A. Hempel on Brazilian Coccide. 123 
Boiled in a solution of KOH it colours the liquid deep pink. 
The antenne are short and nearly of equal thickness through- 
out. The lac-glands are large and very near the large 
spiracles. Around the opening of the large spiracles and 
between these and the other spiracles are many spinnerets. 
Rostrum and mentum large; rostral loop short. The legs 
are represented by inconspicuous short, sharp tubercles. On 
the ventral surface in front of the antenne there are two 
groups of about sixteen elongate glands each, and behind the 
antenne there are two more groups of from eight to ten 
glands each. The dorsal horn is 146 millim, long, sharp, 
with two small tubercles at the base. The anal ring bears 
ten long sharp hairs, which protrude almost their entire length 
beyond the chitinous collar or caudal ring, and flare outwards. 
The caudal ring is large and bears many minute tubercles 
and a few hairs at the base. This ring terminates in ten short 
chitinous plates, which have nearly parallel sides and the ends 
deeply and irregularly incised. ‘The four tubercles on the 
dorsal surface between the caudal ring and dorsal horn are 
small, but bear from forty to fifty vound spinnerets each. 
The entire surface of the body is covered with small tubercles, 
each one terminating in a hair. The ventral surface has 
the appearance of bearmg many transverse rows of minute 
hairs. 
Hab. Cachoeira and Ypirauga, State of S. Paulo. On 
twigs of a bush of the order Myrtacee. 
Many of the insects are covered with a black fungus. The 
3 tke As 
individuals are usually distinct, the lac seldom fusing. 
Tachardia rose, Hempel. 
Female test elongate, deep orange-red in colour, with a 
hump on the dorsum and three processes on each side radiating 
from the lateral margin, giving it a star-shaped appearance, 
There are usually two fine filaments of white secretion in 
front of the dorsal hump, probably arising from the large 
spiracles. Many of the individuals are distinct, with soft 
plastic lac, but in the older specimens the lac is hard and 
brittle and usually fused into larger masses, 
Average size :—Length 4 millim. ; width 3 millim. ; height 
1:75 millim. 
The adult female, denuded of wax, has three small tubercles 
on each side. Boiled in a solution of KOH it colours the 
liquid a deep red claret-colour. Antenne small, club-sha ped, 
with two or three short hairs on the last joint. The joints 
are confused and indistinct, but appear to be four, Length
