THE BEETLES OF SOUTHERN ARIZONA. 200 



This would be expected from the desert aspect of the neigh- 

 borhood, except in the river bottom, where the Papago Indians 

 have a small reservation on which they successfully cultivate 

 their accustomed crops. 



By this time the rainy season had thoroughlv set in and 

 insects might soon be expected to appear in larger numbers. 

 Repairing now to Tucson, which was reached on the fourth of 

 August it was found that the street lights, after a storm, 

 attracted vast numbers of beetles, manv of which had not 



J 



been met with in the course of previous work. Bv far the 

 best captures were made here in the three weeks following, 

 the regular labor being broken only by two short excursions 

 made in company with Dr. Peters, whom I again had the 

 pleasure of meeting. The first of these trips took us to the 

 Tucson Mountains, where some very rare specimens were 

 obtained. Whether or not any of these mountains extend up 

 into the pine belt, I am unable to say — but at the points we 

 reached, the giant cactus had not yet ceased to grow. The 

 Santa Rita range, which we next examined, is much more 

 lofty, but we did not get far above the cactus line — only a 

 short distance into the oak scrub. Still the herbaceous plants 

 are largely different from those of the Santa Cruz valley 

 and some of the beetles were not contained in anv of our pre- 

 vious collections. The genus Acmceodera was rlnelv repre- 

 sented on composite flowers, though not seen abundantly anv 

 where else that summer. 



, For assistance in identifying material I am under obligations 

 to Capt. Thos. L. Casey and the late Dr. Geo. H. Horn, as 

 well as to several specialists who have examined specimens 

 belonging to those families with which they are most familiar.
