TELEAPOLYPEMUS is nota rare in 5th in the E ist, but tha fi i ding 

 of a large number of -their cocoons on apple, prune and willow in 

 the vicinity of Los Angeles certainly is of interest, as I c in tiud no 

 record of their having been taken here before. 



Mr. O. W. Howard sent me 50 cocoons taken as above noted, and 

 lie succeeded in raising about 75 by enclosing the moth with uetting- 

 on our common pepper ti-ee, thus establishing a new food plan 

 for polyphemus. Early in January three dead cocoons were found 

 well up in the Cahueuga Mountains, northwest of the city, ami a 

 number in the brush about the mouth of the San Gabri I Canon. -28 

 miles away, so the moth is evident! v pretty well established. 



All the Eastern cocoons that I have seen are wrapped in leave* 

 with no attempt to fasten the stems to the twigs, and reidily de- 

 tach and fall to the ground, but these were closely woven the full 

 length of the stem, and including the twigs adjoining thus being 

 permanently attached to the tree. The moths begin to emerge May 

 30, and continued to cement the rate of three or four a week until 

 the past few warm days, when tive appeared on the board this 

 morning. KKANK S. DAUGK.TT,
