dant at depths varying from not more than three or four inches below the 
sod to over a foot below. All were active and most were found in their 
usual feeding position. They were for the most part fully grown. Other 
lots of the grubs were obtained from the same locality in March and 
April. Some of those found in March were in frozen soil, but they did 
not seem affected by it, but were as lively and vigorous as in summer; 
others were black and dead. Several of those found at this time were 
infested by from half a dozen to a dozen mites of the genus Tyrogly- 
phus or Rhizoglyphus, I think. A lot set aside for identification was 
unfortunately lost; hence IL can not with certainty give even the genus. 
Although the mites appeared to be parasitic on the larve, the latter 
were not apparently injured by them. On larve dug early in April 
Cordyceps ravenellii Ber. was growing. From each lot of larve, from 
twenty-five to fifty were taken and placed in large boxes of soil and 
supplied with turf. While most of these larvee were of full size, 7. e., 
from 1.4 inch to 1.6 inch long, two other smaller sizes also occurred, 
one of them about 1 inch long, and the smallest 0.5 inch to 0.6 inch 
long. The color is more nearly pure white in the smaller larve and 
. these are more active than the larger ones. The confined larve were 
hatched during the spring and summer, in order that any tendeney to 
pupation might be noted, but most of them were unchanged until Sep- 
tember, when they pupated, and the last of September and early in 
October all left the earth as perfect beetles. About 4 per cent of the 
several hundred kept changed to imagos in early summer. 
Only larve were found January 28, but at each subsequent digging 
a few beetles were found with the larve. They did not voluntarily 
come from the ground till about the 1st of May, from which time they 
grew more and more abundant, until early in June, when they began 
to decrease, and by the last of June all had disappeared. It should be 
said that the spring was cold and that the beetles were far less numer- 
ous during the season than usual. Dr. Horn’s paper in Trans. Am. Ent. 
Soc., Vol. xtv, and especially Prof. Smith’s article in Proc. Nat. Mus., 
1888, p.481, enable students of the genus to identify species in a manner 
hitherto impossible. Using the above papers as guides it was found 
that all of the beetles appearing at first were L. dubia Smith, and the 
same is true this present year, for up to this time, May 10, I have found 
only this species. Later LZ. fusca Frohl. appears and soon is as nu- 
merous as J. dubia, and throughout the season these two species, found — 
in about equal numbers, are the principal forms, but now and then a 
stray specimen of several other species occurs. These are L. grandis 
Smith, L. arcuata Smith, L. insperata Smith, L. rugosa Mels., but 
only a few specimens of any of these were taken. 
After the disappearance of the beetles, toward the last of June, 
none are found until the last of September, or early in October, when 
afew individuals of anew brood come from the ground. So far as 
observed these are about equally L. dubia and L. fusca.
