dult) were found in all the fields, usually, however, in trivial num¬ 
bers, collected largely in the silks at the tip of the ear, but also 
ccurnng on the stalks. A few were noticed in the third and fourth 
tages, but none younger than these. But in one corn-field visited 
tere, the bugs were swarming on all parts of the stalks, ears and 
leaves. Scores were collected in the silk at the tip of every ear. 
ieventy-five per cent, of those found in this field were adults* 
numerous dead ones were seen upon the leaves and stalks and also 
a the silk, embedded in a white fungus, which frequently entirely 
overed the specimen. On the 30th, at Jerseyville, in Jersey county 
, few occurred on the corn, of all sizes, from the adult down ' to 
lose just hatched. These young were unquestionably the descend- 
nts of the adults found with them, and consequently represented a 
rter brood than that hitherto discussed. Large numbers of fresh 
>upa skins were seen, and many of the adults had but just moulted. 
. few dead specimens appeared, and a few of these had been 
ttacked by the same fungus as that noticed at Jacksonville. 
On the 4t.h of September, at Normal, nearly all were adults, and 
'ccurred chiefly in the ears, both in the silk at the tip and behind 
re husks. At Mason City, on the 6th of September, they were 
umerous, but not abundant, upon the stalks of the corn and also 
i smaller numbers in the silks. On the 15th of this month, adults 
;erq noticed flying in small numbers at Normal. On the 16th, those 
emaming in Mr. Conner’s field were all winged, occurring behind 
le sheaths and in the tips of the ears. Very few were present here 
owever. They seemed to have generally abandoned this field as 
ist as they acquired wings. During a trip to Southern Illinois, 
ley were found sparingly from September 9tli to 25th, at numer- 
uis points, from Villa Bidge to Vandalia. Nearly all were adults, 
fie remainder being in the preceding stage. Those noticed were 
b tween the leaves and the stalk, and in the husks of the ear. A 
iw were likewise seen at Carmi, on the first of October, all adults, 
n the 25th of September, at Normal, they were scarce in all the • 
jelds examined, chiefly nestled among the husks, sluggish and 
pparently not feeding. On the 3d of October, numbers were found 
pon the wing, and they were also abundant in the University 
round, upon grass and weeds. They were now rather rare in the 
prn-fields, having evidently scattered in search of winter quarters, 
n the 17th, a very few adults were seen behind the sheaths of 
)rn, but none could be found elsewhere, not even about weeds or 
ader rubbish. 
On the 7th of November a careful search w T as made in corn that 
ad previously been badly infested by them, but none were to be 
!*en upon the stalks or under the rubbish on the ground in the 
/Id; in the thickly-matted grass adjacent only a single specimen 
as discovered by fifteen minutes’ search. On the 14th of this 
onth the weather was cold and raw, and the ground was frozen 
)out the hills of corn from an inch to an inch and a half in 
i ipth; a very few bugs were now found in the crevices of the 
•ound, among the roots near the surface. At Champaign, on the 
th, I visited again the field of Bogardus and Johnson, making a 
.reful search for hibernating individuals about the stalks, under 
e w T eeds in the field, and beneath the rubbish collected about the
