Field Notes on the Adults.— Out OAvn notes throw some light on the 

 habits and behavior of the adult beetles. 



Hibernation. — The winter is passed in the adult stage, presumably 

 under any adequate shelter. In ."December, 1906, I found many sluggish 

 adults inside of cracked gourds in a field in Brunswick County, and 

 this may be a common place for hibernation. On October 31, 1900, at 

 Ealeigh, I found many eating into and inside of gourds which were 

 green, but the vines of which Avere dead. But I helieve that many (per- 

 haps most) of them pass the winter under rubbish or trash. 



Emergence in Spring. — March 10, 1904, I found adults common in 

 blooming strawberry fields in Pender County. By March 25, same year, 

 had noted them feeding on opening leaf-buds and flowers of fruit trees 

 at both Southern Pines and Raleigh. In 1907 I noticed first adults in 

 flight at Raleigh on March 22. In 1908, on March 25, adults were 

 plentiful at Ealeigh feeding on many kinds of new vegetation. In 

 1909, April 16, at Louisburg, Pranklin County, I found them abundant 

 on young pear foliage, many females heavy with eggs ; though an assist- 

 ant noted adults mating freely as late as May 17 in 1907, at Raleigh. 

 In 1913 I saw the first active adult in garden at Raleigh on March 29. 



Later Habits of Adults.— In October, 1900, I noted that adults were 

 common on goldenrod and aster. On May 17, 1907, Mr. R. S. Wog-
