number of young were found underneath. Apparently the species is 

 viviparous in this latitude, as recorded of it farther south by Dr Riley. 

 In Florida all stages have been observed during the winter, and it hiber-

nates as larvae at Washington, D. C, according to Dr Riley. The num- 

 erous young on the branches and those still issuing would indicate that 

 the larvae must hibernate in this stage. The only observed difference in 

 October between those which had issued some time before and those 

 emerging, was in the color. The older ones still retained the larval form, 

 but they had turned black, were closely apphed to the bark and attached 

 by a slender thread. In this condition they were apparently ready for 

 hibernation, since upon being disturbed there was no effort to move off, 

 as in the case of younger individuals. 



In this latitude there is probably but one annual generation, as there 

 is little chance that young would be produced earher here than in Mich- 

 igan. Prof. Cook states that they appear late in August. 



This insect produces a large amount of honey dew, which has a 

 nauseating odor. It has also been observed on clover by Prof. Cook. 

 A parasite, Coccophagiis flavosciitellum Ashm., has been reared from this 

 scale insect (Howard, see citation). 



Remedies. In case of a bad infestation, it would be well to scrape 

 all the old insects from the branches in the autumn, and then treat the 

 infested limbs with either whale oil soap or kerosene emulsion. If this 

 is undertaken before many young have emerged, the trees should be 

 nearly freed from the pest.
