RESULTS OF THE ENTOMOLOGICAL COLLECTING 

 EXPEDITION 



Of the University of Kansas to Pima County, Arizona, in June and 

 July, 1906. 



By F. H. Snow, University of Kansas, Lawrence. 



This paper also includes Arizona material of former expeditions not previously identified, the 

 location being given in each instance. 



^T^HE twenty-fifth collecting expedition in charge of the writer 

 ■^ spent nine days in camp on the ranch of Mr. Thomas C. Kurtz, 

 one and a half miles north of the railroad station at Tucson. The 

 members of the party, in addition to the director, were Leverett A. 

 Adams, for several years assistant in the department of zoology in 

 the University of Kansas, now a member of the faculty of the State 

 Normal School, at Greeley, Colorado, and S. E. Crumb, a student 

 of the junior class. In the vicinity of this camp 3214 specimens 

 were collected during the nine days, of which more than 2000 be- 

 long to the order of Hymenoptera. On July 3 the collecting 

 party was increased by the arrival of Mr. Eugene Smyth, of Topeka, 

 who had accompanied the writer on four preceding expeditions. 

 On July 4 we started by wagon for Sycamore canyon, also called 

 Brown canyon, in the southern portion of the Baboquivari moun- 

 tains, and located our camp at a distance of sixty miles southwest 

 of Tucson. This entire region is a typical desert area, and we 

 found no small difficulty in obtaining a suitable supply of drinking 

 water. At this second camp we collected insects for three weeks — 

 from July 6 to 26 — securing over 11,000 specimens, which, added 

 to the Tucson material, made a total of 15,000 specimens as the re- 

 sult of the entire period of less than five weeks of actual work. At 

 the second camp the Coleoptera took first place in the number of 

 species and specimens collected, amounting to nearly one-half of 

 the entire material. In regard to the scientific value of this mate- 

 rial, Mr. Charles Liebeck, of Philadelphia, to whom I submitted 

 many species of the Coleoptera which I was unable to identify from 

 our previous collections, made the following statement: "The usual 

 handicap, lack of Mexican material and synoptical tables in the 

 Biologia Centrali-Americana, has hampered me more with this lot 

 than with any other I have ever handled, due to the great number of 

 apparent new species; and I must say that your 1906 catch certainly 

 shows the finest lot of species I ever handled in one consignment.
