ably Lepyronia sordida, the adult of which was taken on this 

 plant. 



Euthamia sp. (Solidago). — In a small patch of this plant 

 the phytophilous Hesperotettix pratensis was quite abundant. 



Along the railroad track near Forest City, Phacepholis Can- 

 dida was abundant on some undetermined low weeds. 



For the concluding group of inhabitants of the open waste 

 sandy land I may appropriately mention our herpetological ob- 

 servations in this region, which cover all the characteristic ver- 

 tebrates noted. There were four of these: the box-turtle (Cis- 

 tudo Carolina, PI. XII., Fig. 2), the striped lizard ( Cnemidophorus 

 sexli H eat us), the hog-nose snake {Heterodon simus) , and a small 

 Hyla, or tree-toad. Ten years ago the box-turtles w T ere quite 

 common at the Devil's Hole, but I have seen very few of late 

 years. The striped lizard ranges throughout the valley, and is 

 not rare here. The hog-nose is quite common, especially along 

 roadsides and sandy shores. 



The general arid aspect of the sandy regions is relieved by 

 the moist growth at the bottoms of deep wind-excavations in 

 the sand, and here a very different fauna obtains. Adults of 

 aquatic neuropteroids, such as Hexagenia and various dragon- 

 flies, rest on plants here or fly about; Locustidw and their nymphs 

 suddenly come into prominence, — for example, Xiphidium, Scud- 

 deria, and Amblycorypha uhleri',&nd moisture-loving grasshop- 

 pers, such as Dichromorpha viridis and Orphulella pelidna, replace 

 those of the dry sand. A variety of rare and interesting Hem- 

 iptera occurred on this vegetation; for example. Homwmus cenei- 

 frons. Long grass on the sides of hollows of tlys kind was well 

 populated with elongate tryxaline grasshoppers, Mermiria bi- 

 vittata and neomexicana and Syrbula admirabilis, the latter in 

 the drier and sparser portions. 



The sandy roadways have some fairly definite insect asso- 

 ciations. Here Aphodius rubeolus, Canthon latvis, Onthophagus 

 hecate, and 0. pennsylvanicus are found at the usual occupations 

 of these genera; Anthrax, Erax, and Gieindela formosa generosa 

 and smiellaris lecontei fly along the bare wheel-track lines; Am- 

 mophila is common, and Megachile latimanus and Epeolus lunatus
