SUBFAMILY COCCINJE. 
GENUS AKERMES COCKERELL 
Following Prof. Ncwstead’s lead, the two species discussed 
below are continued in the genus Akermes, although a com- 
parison of the two with the genotype raises a very serious question 
as to the correctness of such generic association. 
Akermes quinquepori (Newstead) 
Reference. — Newstead Bull. Ent. Res. vol. 7, 1917, p. 349. 
This species is represented in the material submitted by 
Dr. Wheeler by three lots of specimens. Dr. Wheeler’s notes 
in regard to these are as follows: 
“No. 76. Barakara, B. G. July 15, 1920. Found in a large 
colony of ants ( Camponotus novogrenadensis Mayr) which had 
their nest within that of Hamitermes excellent Emerson (MS.) 
in the bark of a large standing tree. The galleries of the ants 
inter digitated but did not communicate with those of the ter- 
mites. The coccids were in the ant galleries and attached in 
great numbers and in all stages to the surface of the tree itself. 
It was difficult to remove them without breaking them. A 
large piece of the inner bark with the coccids was removed with 
large coccids attached to it. The insects were seen to exude 
copious drops of clear honeydew from the brown anus on the 
dorsal surface.” 
“No. 87. Barakara, B. G. July 15, 1920. In the cavities 
of a stem of a Cecropia angulata I. W. Bailey. The ants in this 
Cecropia were a species of Azteca not yet identified.” 
“No. 164. Kartabo, B. G. July 17, 1920. In the cavities 
of the stems of a seedling Cecropia (name to be supplied later). 
The ants belonged to a black species of Azteca not yet identified.” 
Through the kindness of Mr. G. E. Bodkin in locating the 
same, the writer was given the opportunity of collecting specimens 
of Prof. Newstead’s species from the same tree and the same 
ant nest that produced the individuals described by him
