These figures indicate that the cultivation of vegetables could well 

 be extended by those who have sufficient land at their disposal, and 

 further study of the various vegetable insects, especially as regards 

 control measures, would be of great importance in encouraging such 

 cultivation. 



THYSANOPTERA AND HEMIPTERA, OR SUCKING INSECTS. 



Thrips tabaci Lind. 



This well-known species, the onion thrips ; has been found attacking

Peregrinus maidis Ashm.

 sible for the attendance of various ants and flies.

 tioned by Mr. Barrett in 1904 * as having " injured beans and other 

 small crops," and in the same year this species was mentioned on
