bunch up in cool or rainy weather on the dead weed stems; 

 while the border of dandelions and .sweet clover is visited by 

 numbers of Volucella fascial us. Dielis plumipes, Agapostemon 

 splendens, etc. In the level and least sandy roads are found Me- 

 lanoplus femur-rubrum and Cicindela punctulata, and, under 

 boards, along the fence lines, GnjJhis pennsytvanicus, Carabus 

 sylvosus, etc. 



Culture of various kinds accounts for the presence here of 

 the potato-beetle, box-elder bug, chinch-bug, potato stalk-borer, 

 and house-fly, and of the male of Blatta orientalis at an electric 

 light. In a street at Forest City, adults of Lucanus placidus 

 were coining to the surface at the base of shade trees along the 

 walks. 



Taking up now the forested ground, a situation claiming 

 especial attention is the very sandy black-jack land, with its 

 matted scrubby growth (PI. XXL, Fig. 1 ). whose contribution 

 to our list of sand insects was by no means small. The char- 

 acteristic grasshoppers here were Melanoplus luridus, impudicus, 

 scadderi, a,ndfasciatus, and Chloealtis conspersa. Along the roads 

 were Hippiscus phoenicopterus and Schistocerca alutacea, (PI. 

 XVIII., Fig. 1,) which latter liked to fly up into the oak brush 

 when disturbed. Calopteron terminate and C. reticulatum were 

 common. The stalks of Scrophularia nodosa were loaded with 

 Cosmopepla carnifex in June, and small oak sprouts had at that 

 time a great many small click-beetles (Limonius quercinus) on 

 leaves and stems. 



The marginal sand ridge, with leaf-mold and a better de- 

 veloped forest (PI. XXL, Fig. 2), had about the usual central Illi- 

 nois fauna for forest situations. 



Finally, the long stretch of moist sandy shore (PL XXIII.) 

 extending from Quiver Lake to Riverside Park, a distance of 

 about three miles, added new elements to the sand fauna, partly 

 due to the presence of the river and partly to the sand, and 

 seeming but doubtfully eligible to a place in these studies. The 

 river-shore-sand grasshopper, J 1 /////ryv//yoyy/.sr//y'/y^/. whose habitat 

 extends in a slender strip along the southern seashore and up 

 each shore of our larger rivers, is here in evidence, as usual.
