Along the narrow strip of wave-washed beach at the foot of 

 the sand bluff were great numbers of tiger-beetles, Cicindela 

 cuprascens and C. kirticollis, also Paratettix cucullatus. Bembid- 

 ium was found along the water margins. Under the driftwood 

 were Chlcenius sericeus, Patrobus longicornis, Platynus octopunc- 

 tatus, and other Carabidce, also Gryllus pennsylvanicus. In the 

 drier sand higher up we have noted Tetragonoderus fasciatus 

 and Blapstinus interrupt us. Under and about dead fish, turtles, 

 etc, are found Saprinus, Bister, Silpha, and Cercyon, often in 

 great numbers. Anthrax and Bembex are also common, flying 

 about on the dry sand. Among the insects on plants along the 

 sandy beach in June, and conspicuous by reason of their great 

 abundance, were the daddy-long-legs {Liobunum) on mulleins 

 and other plants, and Metackroma angustulum, M. parallelvm, 

 and Melasoma lapponica on willow. Even on straggling willows 

 and poplars among the sand hills inland (PI. XX., Fig. 1), both 

 species of Metachroma were very numerous, and M. parallelum 

 abounded also on a variety of plants. There is no previous 

 record of their occurrence this side of Kansas except that of 

 parallelum by Brendel ('87) in this same region. Disonycha 

 5-vittata, very variable in markings, was also taken on willow 

 among the sand-hills. 



Annotated List of Species. 



The following list includes all species taken within the 

 limits of the western Illinois sand regions. No attempt to re- 

 strict it has been made, since few faunal lists have as yet been 

 published for Illinois. The determinations are my own except 

 as otherwise stated, and much time and pains have been taken 

 to make them accurate. 



I am under obligations for help in securing determinations 

 to Dr. L. O.Howard, Professor Herbert Osborn,Mr. W. S. Blatch- 

 ley, Mr. A. L. Melander, Mr. E. S. G. Titus, and Mr. Frederick 

 Knab, and their cordial cooperation is gratefully acknowledged. 

 My friend and collaborator, Mr. Gleason, has helped me with 

 the plant names. Mr. J. J. Davis and Mr. R. 0. Johnson, of 

 the University of Illinois, who accompanied me on the field
