INSECTS INJURIOUS IN 1902. Dal 
With the exception of a slight outbreak near Twin Valley in 
Norman county, which the Entomologist found to be not serious, 
an early and limited attack near Glyndon in Clay county and the 
crisis at Perham wnich was promptly met by plowing, Gentilly 
and the Hill River district were the only places known to be seri- 
ously affected. 
As stated above the Lesser Migratory or White Mountain 
Locust was the offender and was practically the only locust found 
on the stubble. In grass and other rank growth (in one instance 
in a clover field in large numbers and also in timothy) I found the 
Two Striped Locust M. bivitattus (see colored plate) ; some few 
specimens of Chortophaga viridifasciata (Fig. 14), have also been 
seen and later the always numerous Red-legged Locusts, M. femur

rubrum. The usual quota of Carolina Locusts so often mistaken 
for the Rocky Mountain species were observed everywhere. 
In July I visited this locality again. All the grain had headed 
but was still in the milk. I then found the hoppers winged and 
in enormous numbers about one-half mile south of where I had 
first seen them. They were feeding upon the soft wheat kernels 
and four out of every ten heads of wheat were being preyed upon 
by hungry individuals. As far as one could see and observe such 
small objects in looking out over the grain, grasshoppers could 
be distinguished by the thousand (see Fig. 11) and it is in the 
stubble here later, undoubtedly, that eggs were laid. I also learned 
at this time that the pests had spread further west beyond the 
broken belt of timber which had formed a temporary western 
barrier. 
My last trip to Hill River was on Sept. 3rd after harvest. I 
then learned that hoppers were observed laying their eggs late in
