114 Mr. A. Hempel on Brazilian Coccidee. 
are covered with small and large round spinnerets and hairs 
with tubercular bases. 
Female (second stage).—Test elongate, elliptical, the ends 
nearly acuminate. It is rough like the adult, but not so 
brittle. The roughness is due to the fact that the test is 
secreted and formed from small globules of wax. Denuded 
of the test it is oval in form, buff in colour, with eight or 
nine deep transverse furrows on the dorsum. The dorsum 
also bears near the lateral margin the seven pairs of spiracles, 
which open into the furrows. ‘The external openings are 
surrounded by a small quantity of white powdery secretion, 
and are readily seen with a lens. Under the insect there is 
a slight cushion of white powdery secretion, 
Boiled in a solution of KOH it makes the liquid turbid, 
giving it a light yellow colour. The antenne are represented 
by short thick tubercles, with a terminal brush of stiff hairs. 
Legs are represented by thick tubercles, with minute claws. 
Rostrum is large, extending from the antenne beyond the 
first pair of legs. Mentum large, dimerous. Rostral loop 
very long, usually coiled. Two small oval eyes are situated 
just in front of the antenne. Collar on the intestine, and 
spines and spinnerets the same as in the adult. The abdomen 
also bears on the ventral surface masses of minute hairs. 
Hab. Pocos de Caldas, State of Minas Geraes. Very 
abundant on limbs and trunk of Schinus sp., a kind of matté. 
Frequently the tests of 2-6 individuals coalesce, forming 
one mass. ‘I'he females of the second stage usually secrete 
from the caudal end a stiff tube of white wax, which usually 
has a small drop of clear liquid on the end. I had at first 
thought this insect might be a Hermes, but on studying it 
closely I found that a new genus had to be erected for it. 
Prof. TI’. D. A. Cockerell, to whom I sent specimens, also 
thought that it belonged to a new genus. 
Genus Stigmacoccus, Hempel. 
Adult female forming a more or less spherical test, with a 
large aperture on the apex. Antenne 7- or 8-jointed. Anal 
ring hairless. Abdomen with eight pairs of spiracles. 
my Qed ? A 
I'ype Stigmacoccus asper, Hempel. 
Stigmacoccus asper, Hempel. 
Adult female test large, chrome-yellow, the outside 
blackened by a fungus and very rough; inside smooth and 
shiny. ‘The shape is more or less spherical, slightly com- 
pressed laterally, with a round or elongate hole on the apex.
