At Savoy, in Champaign county, they were found June 1 
noving from grass into corn, and completely devouring the latter 
is they went, .their mode of attack being muchjike that or die 
army worm. The area then invaded was about foit} lods long 
by twenty wide. One hundred and twenty worms were counted 
about a single hill, and during a warm rain the ground was nearly 
covered by them. The mode of feeding was here seen to be dif¬ 
ferent from that of the cutworms generally, the com leaf being 
seized by the pendent tip, drawn down, and eaten from tip to base. 
These larvse were nearly all full grown, but a fev remained not 
more than a third the size of the largest. In gardens they were 
at this time especially destructive to sweet potatoes. Jmidences of 
disease were here apparent, many cutworms being pale and limp, 
and others shriveled and blackened. 
June 3, they were still active in Champaign county in corn fields, 
about four acres of one field near Philo having been lately de¬ 
stroyed by larvae which were mostly full grown, some here having 
already shortened for pupation, but others being not more than 
half size*. 
June 10, they were still rarely seen in potato fields, cutting off 
the plants at the base, but in corn their work seemed to be at 
an end. 
June 12, they were still abundant and destructive in beans on 
the experimental farm at Urbana. 
June 18, their earthen cells were found one to three inches be¬ 
low the surface in clover fields previously denuded. 
In the breeding cages, specimens from Southern Illinois received 
April 23 and 28, about full grown when taken, reared on clover 
(which they selected from a sod of clover and blue grass mixed), 
were full grown May 18. June 9 a few- were still feeding, al¬ 
though nearly all had entered the earth and shortened up for 
pupation. 
June 17, only shortened larvae were found in the cells examined, 
as again August 6; but September 23 the first imagos appeared. 
September 27 many more were out, and numerous eggs were found 
on the dead leaves and stems of clover in the breeding cage. 
October 4, several others had emerged, and still a fev moie by 
October 13. Our miscellaneous electric light collections yielded 
the imago of this species froln September 15, 1886, to Septembei 
24; and again from September 12, 1887, to September 20 and 21, 
at which time collections ceased. At the latter dates they weie 
seemingly increasing in abundance.f- 
*It was tlieir habit in corn fields to make a short burrow, usually opening at thebase of a stalk, 
the terminal portions of whose leaves would commonly be found eaten a\\a\ 
tAgricultuTal correspondents reported to the State Department of Agriculture and to the 
“Farmers’ Review’’ of Chicago, that cutworms (whose habits make it likely that reference was had 
chiefly to this species) occurred in destructive numbers in Williamson, V ayne, and Jackson counties 
in May; and in Brown, Cass,Christian,Coles,Douglas,Ford, Franklin, (; [“h J^ie 1 ' Scimv"
