l)uncli up iu cool or rainy weather on the dead weed stems; 

 while the border of dandelions and sweet clover is visited bj^ 

 numbers of VoIkci'JIk fasciafiis, Die!>>i pliDtiipes. Af/njiosfeii/on 

 sj)l('}uh')is, etc. In the level and least sand}' roads are found Me- 

 hiiKiphis feiii'ir-rnhnim and CicindeUi piiiictiilata, and, under 

 boards, along the fence lines, Giy//hifi /)i'niisi//raniriifi, Carabiis 

 si/Irosiis, 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 B/affa oricntnlis at an electric 

 light. In a street at Forest City, adults of Liicaniis p/achhis 

 were coming 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 scru!)by growth (PI. XXL, Fig. 1), whose contribution 

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

 acteristic grasshoppers here were Melfiiiopliis hiriihis. hupiidiciis, 

 HCiuhleri, -Axid fascidtiis, and CJilocaJtis conapcrsd. Along the roads 

 wei'e Hipp/siiis j//iiri//c(>j}fi-rns and Srliisfoccrcd nhifdcea, (PI. 

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

 when disturbed, t'a/ojjferoii fcrun'tHi/c and ( '. rfficn/afiiiii were 

 common. The stalks of iS'rn*y*A/^/r^//(/ ;/o(/(w/ were loaded with 

 Co.'^iiKipcji/o ciiniifcx in June, and small oak sprouts had at that 

 time a great many small click-beetles (Litiiot/iiis <jncrr/iiiis) 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 (PI. 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 dou)»tfully eligible to a place in these studies. The 

 river-shore-sand grasshopper, Trimcrufi-opi.^ cifriiKi, 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.
