life. — a single generation a year — on the apple tree. This is the real 

 apple leaf-hopper, but in most of the work on that so-called species 

 these two and roscc have been mixed." 



Aleyrodid;e. 



In August, specimens of " white fly," both adults and nymphs, 

 were observed an Hibiscus moscheutos in one of the nursery blocks) 

 at Rutherford. The specimens were few in number and the species 

 was not determined. The infestation, however, may have been 

 incidental. 



Coccixellim:. 



Both larvae and adults of a few species of Coccinellidce were ob- 

 served on the plants at Rutherford. They were evidently feeding on 

 the plant lice and adults of the following were collected, Hippodamia 

 13-punctata L., H. convergens Guer., Coccinella g^iiotata Hbst., and 

 Adalia bipunctata L. 



Cambium mixer. 



At Atlantic Highlands, N". J., and Rutherford, N. J., what ap- 

 peared to be the work of a cambium miner was observed on the stems. 

 No specimens were found and the identity of the species is unknown 

 to us. 



Erastria amaturaria Walk. 



A loosely folded hibiscus leaf containing a pupa was noted at 

 Rutherford on August 10. The adult which emerged proved to be 

 this species. The species is recorded as common and the larva is 

 said to feed on Polygonum dumetorum, so that the occurrence on 

 hibiscus may be accidental. 



Scudderia texexsis S. & P. 



A visit to Arlington soon after the flower buds became well devel- 

 oped revealed the fact that a number of them had been partially 

 eaten. Closer observation showed that the injury was caused by a 

 species of Locustidae identified by Mr. W. T. Davis as Scudderia 

 texensis. Two specimens of this species were captured while feed- 

 ing on the buds. Other species of Locustidae and Acrididae were also 

 present in the area where the mallows were growing, so that some 

 of them may have been responsible also for a part of this injury.
