some animal of greater intelligence. The larva of this particular spe- 
cies of Agrotis is exceedingly active, reminding one not a little of some 
of the chipmunks among the rodents. 
A second species that much interested meis the larva of an Agrotis sp. 
that was exceedingly numerous upon the college farm and adjoining tracts 
to the eastward of the city. This latter worm worked on various plants 
in the garden, but on the farm showed decided taste for clover. Here 
it literally “lived in clover” in large numbers. - The different kinds of 
clover growing in the experimental plats suffered much. It was here 
that one of the instances above cited of cut-worms cultivating the soil 
occurred. ; 
The remedies used against these different cut-worms varied somewhat 
in their character; but they were chiefly hand picked orcrushed. Many 
of the worms also perished from the attacks of predaceous beetles either 
in the larval or imago stages, and of parasites of one or another sort. 
A few of them also from diseases that resulted from the presence of 
fungi or bacteria. The parasitized worms were the result of the eggs 
laid by Tachina flies in most cases. The A. anneva larve suffered most 
in this respect, on account of their habit of coming out to feed during 
the day-time. 
ARMY-WORM. 
As the State grows older in its settlement the reports of Army-worm 
depredations become more frequent year by year. Last year Lreported 
the appearance and damage by this insect in the extreme northwestern 
part of Nebraska, as well as in portions of southwestern Dakota. 
During the present year several localities in northeastern Nebraska 
were overrun to a limited extent by the larve of Leucania unipuncta, 
None of these areas infested were of very great extent, nor was the 
injury committed complete in any of the cases coming to my notice. 
Millet and oat fields were the chief sufferers. 
A small black fly was bred from larvie received from Mr. J. M. Sey- 
more, of Pender, Thurston County. This fly has frequently been ob- 
served by me at various points in northern Nebraska, where I have 
taken it in my net when sweeping for other insects on the prairie. It 
must be a regular enemy of Leucania unipuncta, and perhaps also of 
other allied species, since it is by no means an uncommon insect every 
year. Others of the flesh-flies (Tachinide) also act as guards against 
this insect’s rapid increase, as can readily be seen from the fact that 
many of the larvee taken have the eggs of these flies attached to their 
bodies. 
Visiting again this year the region last year reported to you as hav- 
ing the insect present in injurious numbers I was pleased to find that 
the Leucania had not appeared in numbers sufficiently great to attract 
the attention of those persons who lost crops by their depredations last 
year. In fact I am pretty confident in asserting that there are no 
grounds for fearing this insect next year, in the State of Nebraska at 
least.
