NOTES ON GARDEN INSECTS. 



By F. M. Webster. 



Pieris rapce was not observed during trip through southern Indiana 

 in June of the present year, and did not appear about La Fayette until 

 after the 10th of July. When it came, however, it was excessively 

 abundant and was repeatedly observed ovipositing on cabbage dis- 

 played by grocers in front of their places of business in the most 

 crowded portions of the city.
