2 THE ENTOMOLOGIST. 



known as Devonshire or woody galls of the oak; but the 

 hypothesis comprehends all known galls. On the other hand, 

 Mr. W. F. Bassett, of Waterbury, Connecticut, U.S., has 

 concluded that certain American galls, the development of 

 which he had watched from the earliest stage, " were only a 

 modified leaf-stem and blade, and that the tuft of long woolly 

 hairs which terminates the cell is only the enormous develop- 

 ment of the leaf's pubescence." (See I^ntom. vi. 552.) The 

 late lamented Mr. J. B. Walsh opposed this idea, and there 

 never has been an entomologist whose opinion is entitled to 

 greater respect. Therefore, although fully convinced of the 

 soundness of my position, I am very desirous it should receive 

 the most searching investigation. These additions will always 

 be signed with my own name. — Edward Newman.^ 



I. RoOT-GALLS. 



The two kinds of root-galls with which we are acquainted, 

 being invariably covered with earth, we rarely enjoy the 

 opportunity of examining them.— (9. L. Mayr.
