H. serrata Desv. "The horn-fly," common throughout the State, but not so 

 abundant as in previous years. Cattle may be protected from its attacks 

 by sponging lightly with fish oil, to which a little crude carbolic acid 

 has been added. 



STOMOXYS Geoff. 



S. calcitrans Linn. The "stable-fly," common throughout the State: a 

 great pest to cattle (Sm). 



MUSCINA Desv. 



M. stabulans Fall. New Brunswick, VI, VII (Sm), Westville, VII, 5, Shark 

 River, VII, 9. 



M. assimilis Fall. Westville, IV, 9 ( Jn), New Brunswick, Monmouth county. 

 VII (Sm). 



MYOSPILA Rond. 



M. meditabunda Fabr. Westville, VII, 21, Clementon, V, 10. 





Family ANTHOMYIDiE. 



The flies of this family so closely resemble those of the preceding that, to 

 the ordinary observer, they seem to be alike. Some of ihe species come into 



houses at times and are not usu- 

 ally noticed as being different 

 from the common species 



In the larval stages the habits 

 differ. Many, perhaps the most, 

 are scavengers, as are the mus- 

 cids ; a few are parasitic, as are 

 the Tachinids ; quite a number 

 feed in living vegetation, either 

 in roots, as the onion and cab- 

 bage maggot, or mining leaves, 

 as in beets. 



The root maggots are difficult 

 to deal with and aot all methods 

 are equally useful in all local- 

 ities. Tobacco, hellebore, kai- 

 nit, lime with carbolic acid <>r 

 turpentine have all been used 

 as repellants or destroyers with 

 more or less success. 

 Bisulphide of carbon injected into the soil has proved useful in some cases, 

 and so has a tarred card surrounding a plant and resting on the surface. The 

 farmer must usually learn by experience the particular method most useful in 

 his locality.
