RESULTS AT ARTESLV. 



The results from the band records at Artesia proved niueh more 

 satisfactory than did those at Carlsbad, and some valuable data 

 were obtained. 



The experiments were installed somewhat later in the season than 

 were those at Roswell, and in consequence the first collection of 

 larvae was not made until June 4, on which date 33 larvae were 

 found. This date may be considered too late in the season to serve 

 in determining the occurrence at this place of the maximum number 

 of first-brood larvae to contrast with May 29, the date when the 

 greatest number occurred at Roswell. 



On July 10, however, 719 larvae were taken from the bands and 

 represent the maximum number for second-brood larvae. This oc- 

 curred just six days earlier in the season than did the corresponding 

 stage at Roswell. 



From the figures at hand relative to the greatest number of larvae 

 to be found in the field at the time of the first collection in Septem- 

 ber, no maximum number can be described, but from previous con- 

 clusions drawn from contrasts with corresponding stages at RoswelL 

 it would appear that the greatest number of third-brood larvae would 

 be found about September 2. 



Regular collections were made on specified dates throughout the 

 season corresponding with the collections made at Roswell and con- 

 tinuing until September 17, when the records were discontinued. 

 The records of these collections are more fully shown hi Table LX.
