1 am not sure that this larva is different from that of Syneda hmo- 

 landU. I have given the notes on both somew^hat at length, but the 

 lines are all the same and the apparent differences may be due to dif- 

 ferent wording and to slight variations in the larva? under observation. 

 The larva of *S'. hastlngsll did not grow vigorously in the latter stages, 

 as the w^idths of head show, and was somewhat undersized, possibly 

 with the markings a little undeveloped. It fed on the same species of 

 Eriogonum as the other larva. 



Eggs from several moths caught flying at Denver and in the foothills.
