Aspidiotus mangiferae Ckll. 
dent can best form an idea of the methods of describing, 
by studying some of the existing descriptions— especially 
those of species which he possesses. 
To collect Coccidae is a very simple matter. All one 
has to do is to take some of the leaves or twigs, leaving 
the insects in situ, and put them into envelopes or small 
boxes, writing outside the name of the plant, locality, 
and collector. Dry material is always better than that 
preserved in alcohol, because the alcohol spoils the exter- 
nal characters, such as the cotton-like covering, etc. It 
is desirable to obtain a plentiful supply of each species 
when possible. 
The Coccidae of Brazil are so little known that a 
collection from any locality would be sure to contain 
many additions to the list. Some species are known to 
me from immature or broken specimens only, and so 
cannot be described or given a place in the following 
table. I have included in the table several genera which 
are almost certain to be found in Brazil, but without 
citing any species. The characters given for these are 
not sufficient to identify them, but are intended mera 
to suggest identities to the student.
