130 PROCEEDINGS OF THE CALIFORNIA 



They were found on the 17th of August, changed from the white and red 

 stage on the 26th, and spun their cocoons on the 14th and 16th of September. 

 In this condition there was no appreciable difference, except that the golden 

 hairs gave rather a richer appearance to the cocoon. The moths emerged on 

 the 1st and the 15th of March, both being females, and presenting, as I have 

 said, no points of distinction from the ordinary coloring and markings of the 

 typical species. For the sake of reference, I propose for this variety the 

 name of Hal. Alni.
