A New EIvM Gale for America. 



Schizoneura lamiginosaf 



A gall unlike any I have seen before was sent me last August 

 from Connecticut by Doctor Britton. It was deserted and 

 brown and dry, but as Figure 139C will show it resembles the 

 pictures by Buckton of lanuginosa so closely that it seems prob- 

 able that it is that species. The gall was apparently an out 

 growth from the twig at the base of the petiole, resulting in the 

 extreme dwarfing of the nearest leaves. It is figured here 

 merely to call attention to the occurrence of such a gall in New 

 England in hopes that specimens may be collected earlier an- 

 other season before the migrants have taken wing.
