Southern Elm Leaf Curl. 



Schizoneura lanigera {americana in part of authors). 



My acquaintance with this form is hmited' to material sent me 

 from the south the spring of 1912. I am not sure of the species 

 of Ulmus it was taken on, but think it was americana. 



Photographs of the curl and the woolly colony on apple, bred 

 from migrants of this form are given as Figures 67 and 68 of 

 Bulletin 217. 



Fig. 131 represents the antenna of the fall migrant {sexu- 

 para) of the same bred colony. (9-12 sub. i.) 



It will be seen that this has the same characteristics as the 

 corresponding form taken on Pyrus or Crataegus out of doors 

 as shown in Figures 129 and 130. It is smaller than many of 

 the out door grown individuals but the overstocked and dwarfed 

 little seedling on which it developed may well be responsible 

 for the size of the insects which were reared through the several 

 generations from the spring migrants in confinement on the 

 same potted apple in confinement.
