The latest additions* to the known species of South Carolina ants 

 are as follows :

Camponotus americanus, male and female; 

 Dorymyrmex pyramicus, male and female ; 

 Prenolepis parvula, female. 

 May : Iridomyrmex pruinosus, var. analis, male and female. 



Lasius nigcr, var. americana was found in attendance upon the fol- 

 lowing aphid : Chaitophorus ncgundinus on box elder. 



Cremastogaster lincolata was found in attendance upon the following 

 aphids, scales and treehoppers : Platycoiis 4-vittata and Platycotis 

 sagittata on oak; Eulccanium nigrofasciatum and Toumyella liriodcndri 

 on poplar; Schizoncura lanigera on apple; Aphis sctariae on wild plum; 

 Lachmts parvus on pine; Eulecanium tulipifcrac on poplar. These ants 

 were found in a large oak gall, Andricus cornigcrus. 



Prenolepis imparts was found attending the following aphids, scales 

 and treehoppers : Aphis setariac on wild plum ; Lachmts australis on 

 pine shoots; Platycotis 4-vittata and Platycotis sagittata on oak; Chai- 

 tophorus ncgundinus on box elder; Myzus ccrasi on cherry; Lachnus 

 parvus on pine. 



Dorymyrmex pyramicus was observed attending the following aphid: 

 Aphis sctariae on wild plum. 



D. pyramicus, var. flavus was found in attendance upon Lachmts 

 australis. 



Iridomyrmc.v pruinosus and Dolichoderus mariae were also found 

 attending this aphid. 



Formica pallide fulva was found in attendance upon Lachnus australis 

 and Aphis sctariae. 



April 15, 1916, the writer noticed Trachymyrmex septentrionalis out 

 for the first time since last fall. Each colony was busy constructing a 

 nest. The peculiarity in the structure of their nests was very notice- 

 able. Every nest had small odd-shaped pellets thrown out 3 to 5 inches 

 in front of the nest in the shape of a crescent. Ants were noted carry- 

 ing apple blossom petals into the nest evidently for the purpose ot 

 forming the fungus on which they are known to feed. 



The identifications of the ants were made through the courtesy of 

 Dr. W. M. Wheeler. Mr. H. F. Wilson kindly identified two species 

 of aphids. M. R. SMITH, Entomological Laboratory, Clemson Agricul-
