gence of moths from band-record larvae collected at Lincoln the same 

 season. From a total of 260 larvae removed from the bands at Santa 

 Fe, 169 larvae, or 65 per cent, proved to be wintering larvae, and 88 of 

 the entire number transformed the same season to emerge as moths.

tions. As in the case of figure 4, illustrating the seasonal history for 

 1912, the periods indicated by these diagrams are averaged or general- 

 ized, and the tables giving actual dates of occurrence should be con- 

 sulted when specific information is wanted. Both of the seasonal- 

 history charts are made on the same plan and the description of figure 

 4 on pages 31-32 will apply alike to both of the illustrations.

Fio. 10.— Curve showing occurrence of codling-moth larvn; under bands on apple trees, Santa Fe, 



N. Mex., VJVi. (Original.) 



SUMMARY. 



In the Pecos Valley of New Mexico the codling moth produced 

 during 1012 three complete generations. In lOl.'i a partial fourth 

 broofl of larvae developed, and it is considered probable that this is 

 of normal occurrence. 



Pupation of overwintering larvae in 1912 began March 15 and con- 

 firiucid for about one. month. In 1913 the first pupa was noticed 

 Mapfh 2'.', and pu[)ii,fiori conl/inucd for 51 diiys.
