Along- the nai-row strip of wave-washed beach at the foot of 

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

 riiprdsrcHs and (\ liirf/roflis, also Priraffffix ciicHl/dfiis. Bcinhid- 

 itim was found along the water margins. Under the driftwood 

 were Chhiniiis sericrtis. P(ifr(i/>iis iDi/t/iconn's, P/ati/iiiis ocfopinic- 

 fafiis. and other Carahidir, also (rri/f/iis peiuis///r(unnts. In the 

 drier sand higher up we have noted Diriij/oiiof/ci-Hs fasriafus 

 and B/apsfluHs intcn-iipfiis. Under and about dead fish, turtles, 

 etc., are found Srqjrijnis, Hisfci-, tSilp/ia, and Ccrcijoii, often in 

 great numbers. Aiiflu'dx and BcihIh'x are also common, flying 

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

 sandy beach in June, and conspicuous l)y reason of their great 

 abundance, were the daddy-long-legs [Liohiiniiiii] on mulleins 

 and other plants, and Metarliroma (uuiiistidinn, M. parallehun, 

 and MtddsdiiHi /njipoi/ini on willow. Even on straggling willows 

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

 species of Mctucln-onKt were very numerous, and J/, [nirallehim 

 abounded also (ui a variety of plants. There is no previous 

 record of their occurrence this side of Kansas except that of 

 fjdral/i'hnii by 13rendel ('87) in this same region. Disoiii/r//ii 

 5-vift(da, very variable in inarkings, 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 

 pabli.shed for Illinois. The determinations are my own except 

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

 to make them accurate. 



1 am under obligations for help in securing determinations 

 to Dr. L. 0. Howard, Profes.sor 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. (ileason, has helped me with 

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