in the cornfields the beetles do not feed on the young corn plants to 
any extent, but on seedling weeds. ‘They have been observed repeat- 
edly to leave corn plants and crawl here and there on the ground until 
finding a seedling weed, when it would be eaten down close to the 
ground. 
The first signs of injury to corn were observed May 2, when numer- 
ous wilted buds were discovered in a low plat of corn on a low situation 
on the farm. Larvee found at this date were most of them about one- 
third grown; two were found, however, almost, if not quite, full grown. 
The two weeks of hot and dry weather following this date caused a 
general wilting of plants badly injured in the crown, and frequent 
examinations of the roots of infested plants were made. It soon 
became apparent that a rather small proportion of the larve among 
tne roots of plants attacked the crown, causing the death of the plant; 
but that, probably in the majority of cases, the larvee fed on the roots 
or on the outside and under the stem at the origin of the roots. Rarely 
were the roots channeled out longitudinally, but more usually eaten 
into or eaten quite off. On the side of and below the stem of a corn 
plant in four or five leaves channels or grooves may be eaten, the 
larvee not attempting to bore into the heart. Where such is the mode 
of attack, the outer leaves are likely to appear more or less yellow or 
rusty in blotches, or even yellow and dry. When the roots only are 
attacked but little injury seems to result to the corn; in fact, many 
of the most thrifty plants pulled up and examined had as many as 
five and six full-grown larve among the roots. In a word, larve were 
found quite generally among the roots of most plants on low soils, as 
many as three to six to each hill, and in a relatively small proportion of 
cases were plants attacked at the crown, causing the usual wilting of 
the bud. 
The first pupa found in the field was May 8. On May 10 a rather 
extended search proved them to be quite numerous. The first beetle 
of.the new brood was observed May 12, from which date they have 
become increasingly abundant. At this writing, June 12, beetles are 
quite abundant, feeding mainly on the blossoms of various cucurbits. 
The last stragglers of the over-wintered brood had disappeared by the 
last week in May. The broods are thus seen to overlap somewhat, but 
it is likely that these stragglers passed the winter as larve or pupe, 
completing their development in the spring. 
Beetles have been observed feeding on the foliage of the following 
plants: rye, oats, alfalfa, corn, crimson clover, currants, gooseberry, 
and such garden vegetables as beans, beets, squash, cantaloupes,-water- 
melon, cabbage, Irish potatoes, turnips, tomatoes, and on the flowers 
of apple, pear, quince, plum, peach, and cherry. In fact, the beetles 
seem to be practically omnivorous. Larve have been found on the 
roots of corn, rye, Bromus uniloides, and garden beans. On this latter 
crop considerable injury was done, larve boring into the stem and
