the American form is most in evidence a 

 trifle later than that stage. The larvae in 

 each case becomes discolored, changing 

 from its clear normal white to various 

 shades of yellow and brown, eventually 

 becoming nearly black. In American

 over the sealed brood is quite character- 

 istic as they appear at first sunken

 holes. This condition is not observed with

 larva will dry down to a closely adhering 

 scale lying on the lower wall of the cell. 

 Such scales are removed with difficulty,

The treatment for either disease is 

 similar and consists in the removal of all
