Melanopliis scuddcri Uhl. April 4. 



One dead specimen, from under log along fence bordering bunch- 

 grass. A late autumn locust, mature from August 5 to November 22. 

 It is thus able to withstand quite severe frosts. As it is short-winged 

 it is probably sedentary in habit. It is found in borders of open 

 woods, fence-rows, and dry grassy situations. Not a typical bunch- 

 grass species. Its range is "United States east of Great Plains" 

 (Scudder). 



Melanopliis fcniur-ruhnun De Geer. July 23, April 4. 



Common along roadsides and in cultivated fields. Totally want- 

 ing in bunch-grass or blowsand. Found only where a certain amount 

 of humus and clay occurs in the soil. All summer. This is the 

 commonest Melanopliis in northern Illinois prairies. In the sand 

 prairie it is replaced by M. angiistipennis. 



Melanopliis angiistipennis Dodge. July 19, October 8. 



This is the most abundant and most characteristic locust in the 

 bunch-grass. Common throughout the sand region, from July until 

 frost. Angiistipennis is a western species, and was formerly quite 

 rare, but of late years has been increasing in numbers in the West. 

 Its range is from Indiana to Montana and south through the plains 

 region to Texas. This insect is the chief plant-eater in the Illinois 

 sand prairie, and is probably of greater importance in the association 

 than any other species. It is one of the very destructive species of 

 the genus. It is also found on blowsand and in the margin of blow- 

 outs. 



Melanopliis differentialis Uhl. July 25. 



Common in sandy loam flats and along roadsides. Coextensive 

 with cultivation, but very rare in the native blowsand or bunch-grass 

 areas. Two were found in the Devil's Hole region just east of the 

 walnut grove. 



Melanopliis hivittatus fenioratus Burm. July 25. 



Taken in two places where conditions indicated the presence of 

 an advanced stage of sand prairie. The first place was a pasture near 

 Matanzas Lake; the second, a small area east of the black-oak woods 

 near Quiver Station. 



Scudderia texensis Sauss.-Pict July 12, July 19. 



The eggs of this katydid are inserted at the edge of leaves. The 

 adults are active from mid July or earlier till frost. Most of the 

 katydids are arboreal, but this species is not to any great extent. At 

 the Devil's Hole they are found in the bunch-grass quite a distance
