summer of 1900 in a Denver daily about January 15, 1901. I have a 

 clipping only, and do not know the exact date that it was i)ublished, 

 nor the paper in whicli it appeared. The record is as follows :

The following record, kept by an assistant, Mr. Titus, at Fort Col- 

 lins last year, gives approximatelj^ the same dates at which the two 

 broods of larvse reach their maximum and minimum numbers. The 

 dates run a little later at Fort Collins, which is the more northern 

 I)oint. The larvae were taken twice a week by Mr. Titus, so some of 

 the periods are 3 and some 4 daj^s.

The first brood had reached its maximum when the bands were 

 removed the first time, July 25. The great number of ciphers 

 between August 11 and 22 indicate the division between the broods. 

 The second maximum came September 12, and then the numbers 

 diminished rather slowlj^ for the next two weeks. 



Another record kept the same year on a tree growing in the college 

 lawn at Fort Collins gave a similar record, though the first maximum 

 came a few davs later. The record is as follows :
