eiTi Canada (Hamilton), Indiana, Illinois, Wisconsin, Iowa, Kansas, 

 Nebraska (Leng). The species is usually found in sandy soil which 

 has a little more humus than is necessary for C. formosa generosa. 

 Most of the soil in the sand dunes of the Illinois River region has 

 only a very small humus content; generosa is thus the commonest 

 tiger-beetle of the region. In the Lake Michigan sand area more 

 humus is present, consequently scutellaris lecontci is the most abun- 

 dant species. It may be said to be an index of a rather advanced 

 stage of the bunch-grass association. 



Cicindela cuprascens Lee. July ii. 



An elongate green-bronzed species, taken only on the wet sandy 

 margins of rivers and lakes. Taken at Matanzas Lake, at Grand 

 Tower, Waukegan, and in the Indiana lake sand regions. It occurs in 

 Kentucky, Kansas, Missouri, Arkansas, Texas, Nebraska, and Da- 

 kota, on the banks of rivers and on sand-bars. 



Cicindela sexguttata Fab. July 9. 



One specimen was taken in the mixed forest of the marginal 

 river dune. The species is found only in a rather advanced stage 

 in the ordinary development of the deciduous forest, marked by an 

 accumulation of leaf mold, in which the eggs are laid. Advanced 

 stages of the forest are vei*y poorly represented in the sand region; 

 thus the present species is to be regarded as a recent member of the 

 forest association. Its geographic distribution closely parallels that 

 of the deciduous forest province. It occurs in eastern United 

 States and Canada, and west of the Mississippi River in local for- 

 ested areas, being reported from Iowa, Dakota, and Texas (Leng). 



Cicindela punctnlata Oliv. July 12, 29. 



The larvae of this species are restricted to more or less loamy 

 soil; but the adults are often seen on dirt roads and paths, and quite 

 frequently on concrete walks in towns. It sometimes gets into sandy 

 localities and has been taken in the sandy lane near the Devil's Hole. 

 Wickham has found it on dry sand in Iowa, with scutellaris lecontei 

 and formosa generosa. Hart has taken it at the Devil's Hole and 

 Devil's Neck, showing that it is an occasional member of the bunch- 

 grass association. Leng gives its distribution as "Canada west to 

 Manitoba, Maine to Florida, Louisiana, Texas, Colorado, New Mex- 

 ico, Arizona, Ohio, Iowa, Wisconsin, and Illinois." It is a typical 

 plains species. 



Cicindela lepida Lee. July 5. 



In the Havana region ; also in Nebraska sand hills, where, accord- 

 ing to Professor Bruner, it is confined to the bare bottoms of blow-
