 Monodontomerus montivagus Ash. 

 Syntomaspis californica Ash. 



AGAONID/E. 



The one species of this family was imported a few years ago to fertilize 

 the Smyrna fig which previously would not bear fruit. The pollen is produced 

 in the capra variety, and in the figs of that variety the insect comes to 

 maturity. The male is wingless and remains within the fig within which it 

 was born. The female after being fertilized, escapes and carries the pollen 

 with which she is dusted to a young fig, fertilizing it. .;
