is called the Pitiful Lady Beetle, though we know not why, unless it be

 It is jet black. 



In addition to these there are one or more species of parasitic flies 

 which attack the insects and lay their eggs within them, the eggs hatch- 

 ing into tiny maggots which feed within the scale-insects and eventually 

 cause their death. 



In Florida a fungus disease has been found to prey upon the scale to 

 a considerable extent, but attempts to introduce this into other localities 

 have not met with much success.

Recently the United States Department of Agriculture at Washington 

 has introduced from China a species of Lady-beetle closely related to 

 our "Twice-stabbed" species, and indeed one can not easily tell one from 

 the other. This also feeds upon the San Jose Scale, but thus far has not 

 shown itself capable of holding it in practical control. We must still 

 rely upon the spray pump if we wish to keep this pest in subjection. 



History. Where did it Come From?— There has been much dis- 

 cussion in reports and bulletins as to the probaVle original home of the 

 San Jose Scale. From present evidence, however, it seems certain that
