Natural Enemies. 

 No natural enemies of this coccid have been observed preying upons 

 it in this country, so far as known to me. Professor Perkins mentions 

 the occurrence of a number of hibernating lady-birds, on infested trees, 

 the most numerous species being Adalia bipunctata, and suggests that 

 they might possibly feed upon it. The lady-birds were very common in 

 Albany in the summer of 1897, and were noticed in large numbers on 

 trees infested with various species of plant-lice, but none wtre observed 

 actually attacking, or in the immediate vicinity of, the Gossyparia. Many 

 flies and other insects were seen about infested trees, but they were evi- 

 dently attracted by the honey-dew, and could not therefore reasonably be 

 considered enemies of this insect. 



Remedies. 

 Perhaps the best remedy for this pest is spraying with kerosene emul- 

 sion or a whale-oil soap solution. The insecticide should be applied 

 either in the early spring just after the hibernated forms have molted or 

 soon after the young make their appearance. Late in the autumn the 

 insects are so well protected that a solution of four times the normal 

 strength would be needed for killing them. It might be prefer- 

 able to treat the trees at this time, as the insects may then be 

 directly reached in the absence of leaves, although a stronger solu- 

 tion would be necessary than earlier in the year. Small trees have been 

 eftectually cleaned by going over them with a stiiT brush. The brush 

 would be made more effective by dipping it in either kerosene emulsion, 

 or a whale-oil soap solution irom time to time. It may possibly be found 

 that a heavy stream of cold water thrown directly on the insects would 

 reduce them to harmless numbers, if repeated several times during the 

 season. Where convenient, this, from its simplicity, might be preferable 

 to other methods.
