SUBFAMILY COCCINJ^. 



GENUS AKERMES COCKE RE LL 



Following Prof. Newstead'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 (Xewstead) 



Reference. — Newstead Bull. Ent. Res. vol. 7, 1917, p. 349. 



This species is represented in the material submitted by 

 Dr. Wheeler b}" three lots of specimens. Dr. Wheeler's notes 

 in regard to these are as follows: 



"Xo. 76. Barakara, B. G. July 15, 1920. Found in a large 

 colony of ants (Campo'notus novogrenadensis Maj'r) which had 

 their nest within that of Hamitermes excellens Emerson (MS.) 

 in the bark of a large standing tree. The galleries of the ants 

 interdigitated 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 sm-face of the tree itself. 

 It was difRcult 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 angidata I. W. Baile}'. The ants in this 

 Cecropia were a species of Azieca not yet identified." 



"Xo. 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. Xewstead's species from the same tree and the same 

 ant nest that produced the individuals described by him
