larly about the foothills. Among other trees that might be men- 

 tioned are the Douglass spruce {Pseudotsuga mucronata Sud- 

 worth) ; one seed juniper {Juniperus monosperma Sargent) ; 

 alligator juniper /. pachyphloea Torrey) ; four willows, S. 

 nigra Marshall, 5". occidcntalis longipcs Befif, 5. lasiolepis Bent- 

 ham, 5^. taxifolia Humboldt, Bonpland and Kunth ; the quak- 

 ing asp {Popidus trcmnloides Michaux), and another Poptdus, 

 the beautiful Fremont cottonwood (P. fremontii Watson) ; 

 two species of Hackberry (C. occidcntalis Linnaeus, and C. 

 reticulata Torrey) ; the Alexican mulberry {Morns ccltidifolia 

 Humb., Bonpland and Kunth), and two mahoganies (C. parvi- 

 folius betuloides Sargent, and C. p. paucidentatus Watson) ; 

 the Mexican cherry {Prunus salicifolia Humb., Bonpland and 

 Kunth) ; Devil's claws (Acacia greggi Gray), and A constric- 

 ta Bentham ; New Mexican locust (Robinia neomexicana 

 Gray), hoptree {Ptelea trifoliata Linnaeus), wild china tree 

 (Sapindus marginatus Wildenow), Mexican elder (Sambuciis 

 mexicana Preal.) There are many mescals and a few yuccas 

 about the foothills, and both of these, when in blossom, attract 

 innumerable insects and are of the greatest value to the lepi- 

 dopterist, dipterist and hymenopterist. Along the water 

 courses the gnarled manzanita, A. pungens H. B. and K., 

 grows in profusion. There are a few clusters of mesquite, 

 Prosopis glandulosa Torrey, at the base of the mountains and 

 on these there is excellent collecting, especially when in bloom. 



For the lepidopterist. August is the earliest month in which 

 to visit the mountains, collecting from then on being at its 

 best. While a number of single-brooded species will be miss- 

 ed, yet the richness of the fall months more than make up the 

 deficit. Arizona having two so-called rainy seasons — winter 

 and summer— there is but little collecting save in the months 

 immediately following these. The summer rains generally be- 

 gin in early July, and sometimes continue considerably into 

 September. 



The water question in the Huachucas, while not a serious 

 one, is worthy of some consideration. A canteen will prove to 

 be a very useful article. Moreover a small calibre rifle or re-
