stroyed, so that there were veiy few of the latter crawling about. The 

 breeding females had also been eaten out, but this was doubtless a sec- 

 ondary attack, after the eggs were laid, rather than due to the Coccinel- 

 lid larvae, as the females, after depositing the eggs, dried up. In one 

 place, under a cottony mass, I found three parasitic pupa, and in one 

 of the breeding females I found a pupa and a couple of parasitic larvae 

 which resembled very much those of Coccophagvs lecanii. 



July 5th, a box of infested twigs was received from Englewood. 

 There was a Coccinellid pupa in the box, and several larvae were feed- 

 ing on the Pulvinaria egg masses. Apparently they had destroyed the 



eggs and larvae to a large extent, 

 and if they were as abundant in 

 Englewood as indicated by this 

 sending, the conditions there must 

 have been similar to those in 

 Montclair. 



The next visit to Montclair and 

 East Orange was on July 6th. In 

 both places the Coccinellid larvae 

 were still found in various stages, 

 but more pupae occurred, and, con- 

 trary to my first observations, 

 most of them were under the cot- 

 tony masses rather than in the 

 bark crevices. 



July 7th, a few beetles were ob- 

 served in the box in wliich the 

 pupffi were observed June 24th, so 

 that the duration of the pupal 

 stage is about two weeks. July 

 10th, when the jars in the labora- 

 tory were examined, 150 beetles 

 were found, the insects proving, 

 as previously surmised, Tlyperaspis s-'igtmta Oliv., a small, nearly round 

 and convex, black "lady-bird" beetle, with a single red spot on each 

 wing cover. Most of the pupse were found in the "eaten out" cottony 

 masses of the Pulvinaria, while a number were in the dry, curled-up 

 leaves. In the latter places there would often be from half a dozen 

 to a dozen clustered together. 



About this time infested twigs were received from Elizabeth, and
