possibly the work of a nearly spent female or it may be due to an 

 unusually late infestation. 



Oak pill gall (Cincticornia pilulae Walsh). Scarlet 

 oak leaves bearing from two to eight good-sized galls of this species

 by Robert D. McCarter, 50 Church st., New York, accompanied by 

 the statement that practically all the leaves on a very fine oak tree at

 segment of male (left) and female (right), greatly enlarged 

 (original).

 interior had been destroyed and the outer walls were more or less 

 granular and cracked. It is evident that the galls are in a condi- 

 tion to disintegrate readily with the coming of warm weather in the

 tion by raking and burning the fallen leaves, specially if this be done 

 in the autumn. 



Elm bud gall (Dasyneura ulmea Felt) . This species 

 was first reared May 7, 1886 from aborted elm buds evidently taken 

 in the vicinity of Washington, D. C, by Mr Pergande. Apparently 

 the same gall was collected at Jamaica Plain, Mass., by J. G. Jack. 

 The gall is somewhat common in the vicinity of Albany. The
