MAY-BEETLES—( Phyllophaga .) 
Fig. 3. 
The name “White-grub,” as 
commonly used, is somewhat 
indefinite, as the larvae of 
quite a number of species are 
similar in form, color and 
habits. As it is difficult to de¬ 
scribe these in such a man¬ 
ner as to enable the ordinary 
*/ 
reader to determine them, the 
annexed figure of the more 
commmon species—the dark 
May-beetle ( Phyllophaga fus¬ 
ed) in the larva, pupa and 
perfect state is given. 
As a somewhat full account 
of the various species, and 
notice of the remedies recom- 
phyllophaga (Lachnnosterna) Fus& v,jy rohi; quer- mended, are given in my 
cina, Kn.I, pupa in its eartherii^in; 2, larva; 3, n i 
4 , beetle, side and back view. ~ former report, I add here only 
notes relating to their operations on corn in parts of our State, re¬ 
ceived since that report was written : 
H. M. Russell, Urbana, III., in letter dated July6,1877 : “Three years 
ago the summer was very dry here, and the Grub-worm injured the 
corn very materially on high grounds—the common white Grub with 
brown head, such as to all appearances are found about old rotten logs, 
and about in rich ground. These grubs eat off the main root near the 
top of the ground, killing the stalk and causing it to fall over. Some 
fields were almost wholly destroyed; nearly every field about this sec¬ 
tion, wherein w r as any high ground, suffered more or less. Knolls suf¬ 
fered most. I have seen fields in which were knolls and low lands 
wffiere almost every hill on top or knolls was dead, and as the ground 
receded there was less destruction, until in the low ground hardly a 
hill was touched. The damage was done after the corn got some size, 
and considerable of the damage was done after laying by.” 
Wm< A. Griffin, New Windsor, Mercer Co., in letter of July 9, 1877 : 
“Last year, and for several years before, the Grub-worm did consider¬ 
able damage. Have heard of no trouble this year.” 
Prof. T. J. Burrill, Industrial University , in letter of Nov. 24, 1877 : 
“Except wTien Leucania unipuncta (army worm) visits us in great 
numbers the white Grub-worm (Phyllophaga fused) does corn, grass, 
etc., the most damage.”
