inches in length, much larger than any Arizona species, though size 

 is not in itself an indicator of comparative harmfulness. Certain 

 small dark scorpions in Arizona are commonly reputed to produce 

 a more painful wound than the larger ones. We wish to emphasize 

 that fatal, even serious, results from the sting of any Arizona scor- 

 pion are no more probable than such results from the sting of a 

 honey bee. Yet many a person has such an unreasoning fear of a 

 scorpion as to believe that it is time to make a will when stung. 

 In such cases fear produces greater shock effects than the sting 

 itself. Personal acquaintance with many who have been stung, 

 and conversation with physicians, is convincing proof that we need 

 fear them no more than, if as much as, the ordinary bee or wasp. 



The Whip Scorpion probably occurs in Arizona, and is much 

 feared where it is known. (Fig. 10). We are assured by those who 

 have handled this 

 animal alive that 

 it does not bite or 

 pinch, and it cer- 

 tainly has no sting 

 on its whip-like 

 tail and may safe- 

 ly be accounted 

 non-poisonous. It 

 gives off an odor- 

 ous substance for 

 protection when 

 disturbed, which 

 resembles the odor 

 of vinegar, and to

 original use of this word, though it is now most commonly applied 

 in Arizona to the solpugid, as noted above. In some parts of the 

 South this is called a "grampus."

Second only to the tarantula, if not, in fact, its co-equal as an 

 inciter of fear, is the centipede (cientopies), another nocturnal 

 prowler. (Fig. 11). Strangely enough the many small species of 

 these so common under sticks and stones throughout the United
