To the caracters already published in the Re- 
vista do Museu Paulista. Vol. IV, pags. 373-379, 
we can now add the following: The adult female 
is entirely hidden beneath a mass of thick, white, 
curled ou undulated threads. On the dorsuin there 
are four tall, thick tufts of white wax, two or three 
of which are inclined towards the anterior extrem- 
ity, and the remainder towards the posterior ex- 
tremity. The ovisac is very large and wider than 
the body of the insect, and is composed of fine, 
white, glossy, feited threads, ornamented on the ex-

threads. Many old individuals have the dorsal wax 
dark ou dirty in color. The isolated individuals have 
a pyramidal or conical®form, with a longitudinal 
diameter, including the ovisac, of 20 mm., a trans:

The body of the adult female, freed from wax, 
is oval in form, a little the widest near the poster-

a width of 6 mm., and a height of 4 mm. The 
color is yellow on the exterior and reddish on the 
interior, with the antennae and legs dark brown or 
black. In addition to the long and short hairs, the 
derm also has innumerable, circular and hemispaer- 
ica' compound glands, which are about 16 microns 
in diameter, and are composed of a peripheral portion 
in which there are from 9 to 11 small, round ori- 
fices, and a quadrangular central portion with a 
small, circular orifice in the center. These glands 
are more or less constant in size, but the number 
of the orifices in the periphery vary from 9 to 41 ; 
and the central part may sometimes be triangular 
or pentangular ; but the form with the central part
