Honey dew is produced freely. After the third molt it was 

 necessary to remove the colorless liquor daily from the speci- 

 mens which had been placed in vials. Some of the adults from 

 which the honey dew was not removed finally perished in the 

 viscous mass. 



Certain factors as humidity and temperature no doubt deter- 

 mine the movements of the ants with their mealy bugs. One 

 cloudy morning in November the ants in the third nest, which 

 had been transferred from a clover field several weeks before, 

 moved their 24 mealy bugs over a surface path from the nest 

 in a flower pot to a newly constructed tunnel in a bean bed two 

 feet away. After watching this transfer a careful examina- 

 tion of the new tunnel revealed all of the mealy bugs stored in 

 three cells. Three days later the sun was shining and the ants 

 carrying their mealy bugs returned over the same path to the 

 clover roots in the flower pot. Both movements took place at 

 8 A. M. 



Pseudococcus maritimus Ehrh. 



At various times during the fall months and frequently dur- 

 ing the spring months the "flat" mealy bug with lateral "fila- 

 ments which project out from the body" was found associated 

 with the clover root mealy bug. As already stated, this "sum- 

 mer form" proved to be none other than the Baker mealy bug 

 (Pseudococcus I'lai'itiiiuts Ehrh.) which Ferris has reported 

 from the Pacific coast (1918). New York (1918), Florida 

 (1919). England (1919) and Lower California (1921). 



During the progress of this study in Ohio it was taken from 

 sycamore, elder, osage orange and the roots of clover and in 

 Virginia it has since been found ovipositing on the green bark 

 of apple trees. On two occasions it was ovipositing in the stem 

 end of apples. Mr. P. R. T.owerv, who has collected mealy 

 bugs in Ohio for several years, informs me that he has collected 

 it from the following additional hosts: Flowering dogwood, 

 roots of goldenrod, hackberry, hazelnut. hickory, maple. Rho- 

 dodendron maximum and wild cherry. In the botanical green- 

 house at Ohio State University it ranks second to Psendococcns 

 citri Risso as a mealy bug pest. Tn this greenhouse it was 

 found on 26 different host plants. The common name, "omni-
