 and the San .loatpiin Vjdley, California (Coquillett). 



1 have found this insect only upon the sajje brush (Artemisia), and so 

 completely do its ffiay and rusty colors harmonize with its surround- 

 ings that it is extremely dillicult to detect when at rest. This has 

 also been noticed by liruner, who remarks that the resemblance extends 

 to the earlier stajres of the insect. 



Coquillett remarks upon the ease of its tiijjht, describing it as in a 

 straight line, for a distance of from 5 to 20 feet from the ground. He 

 found it devouring the ripe kernels of rye in Calitbrnia, and Riley 

 reports it as injuring cotton in Louisiana. Coquillett regards it as a 

 migrating species, but his specitic statements refer only to short flights 

 from the fields to the tree tops or the reverse, fifty to one hundred 

 yards being the usual distance. In the San Joaquin Valley he found 

 specimens pairing at the last of July.
