•duccd a beautiful male moth. This specimen was hatched o>i the 13th of 

 April, commenced spinning June 3rd and produced the moth September 8th ' 

 — thus requiring the unusually long pei'iod of nearh' five months for its 

 <:'hanges. 



Mr. W. Y. Andrews, of New York, who has taken great interest in the 

 introduction of foreign silkworms, gives me the encouraging information 

 that lust summer, nearly 800 cocoons wei^e obtained from about 1600 eggs, 

 in the vicinity of New York. The moths issued at such irregular intervals, 

 however, and were so scattered among different experimenters, that no fer- 

 tile eggs were produced. 



^t'^'e- -^'l Fama-wuu undoubt- 



'-^1 ediy belongs to the same 



natural genus as Poly- 

 phemus, which it closely 

 resembles in habit and 

 appearance. Its culture 

 mi}- be carried on in 

 th.' same manner as 

 that of cynthia, and it 

 will suffice here to point 

 out such of its peculiari- 

 ti.'saswill guide in its 

 m inagement. 



The escff is rather 

 la •gcr(Fig. 56 shows it 

 of natural size and mag- 

 n'tied) than that of Pol- 

 yphem.us, less flattened 

 and of a pale straw- 

 color with a pinkish 

 tint. It appears brown 

 from being more or less 

 thickly coated with a 

 b:'own tenacious gum, 

 , wliich may be washed 

 , olf by any alkaline 

 flaid. The eggs should 

 hi kept over winter in 

 a temperature never 

 higher than 40° F. When 

 hatching the}^ should be 

 moistened or kept in a moist atmosphere. As in the case of our American 

 Tent-caterpillar, the young larva is fully developed within a month after 

 the deposition of the egg, and passes the winter in a curled-up, quiescent 

 state within the egg-shell. 



The worm thrives best in an atmosi:)here that is cool, moist and shady,
