of insects. The results of such efforts will mainly comprise 

 an assortment of widely diversified forms rather than many 

 representatives of any particular group, unless attention is 

 devoted exclusively to certain kinds. No matter how discon- 

 nected one's operations may become regarding place, time or 

 other conditions in collecting, the final outcome, through 

 skilful classification of the specimens, can be presented with 

 system and order. 



What I consider as my personal collecting, to which all 

 my records pertain, unless in reference to metatypes of two 

 newly described species, has been done aside from any con- 

 nection with the expeditions undertaken by Dr. F. H. Snow 

 for the University of Kansas. Thus restricted, my efforts 

 have been confined to portions of Kansas and Colorado, with 

 the advantage, of course, in favor of my home locality, where 

 flight work was engaged in to a great extent. Only spare 

 time in any instance has been thus employed. All of my 

 specimens, with few exceptions in cases of common dupli- 

 cates, have been added to the entomological collections of the 

 University of Kansas, and from those that are identified I 

 have prepared the following lists of their names, together 

 with records regarding the capture of each species. 



LIST OP HEMtPTEKA-HETEROPTERA. 



Wherever I have collected these insects, rich results were 

 obtained, even at home. The greater part of my collecting 

 in Colorado was done during a visit of six weeks, in the 

 months of July and August, 1894, principally in Colorado 

 Springs. All other collecting in this state has been done sub- 

 sequently on trips of short duration. A list of the determina- 

 tions of species in the order Hemiptera from my first collection 

 in Colorado, and also some undetermined specimens, since all 

 could not be readily identified at the time, were furnished to 

 Profs. C. P. Gillette and C. F. Baker, at their request, by 

 Mr. W. A. Snow, of the University of Kansas, thereby grant- 

 ing them the benefit of the results of study for incorporation 

 in their work entitled "A Preliminary List of the Hemiptera 

 of Colorado," which appeared as Bulletin No. 31 of the Colo- 

 rado Agricultural Experiment Station. The extent to which
