I have not been able to recognize the species Muscat, favillacea 

 Walker and there is no type in the British Museum. 



In concluding these notes I wish to take the opportunity of 

 thanking. Professor Bezzi for allowing me to study this very 

 interesting collection of species of Musca. I will be glad to 

 examine any further specimens of species of this genus from 

 these Islands, and any notes relating to the habits of these species 

 will be welcome.
