deposit their eggs on the underside of leaves or on twigs, 50 to 60 being 

 laid by a single female. They hatch in about 10 days and the red and 

 black young feed on the leaves for about a week arid then begin to prey on 

 insects, becoming full grown during July. He states that there are 

 undoubtedly two annual broods in Massachusetts, the young of the second 

 maturing in September, and that possibly three generations may appear in 

 favorable seasons. 



This species has been recorded from Colorado by Messrs Gillette 

 and Baker, from southern Michigan by Professor Townsend, from 

 Iowa by Professor Osborn, from Canada by Mr Saunders, and Dr 

 Smith states that it is common in New Jersey. The latter is true of 

 both Massachusetts and New York.
