60 Descriptive Zoology. 



Scorpions. Scorpions are found in warm countries, 

 reaching their greatest size in tropical America and Africa. 

 The form shown in Fig. 44 occurs from North Carolina to 

 Florida. Other species are found in the southwestern 

 United States as far north as Kansas. The body consists 

 of a short, unsegmented cephalothorax, followed by a 

 twelve-segmented abdomen. The anterior part of the ab- 

 domen is broad, the hinder part narrow, ending in the poi-

son sting. The sting is painful and serious to man, but 

 seldom fatal. The scorpions are nocturnal, and feed on 

 the blood of insects. Respiration in the scorpions is by 

 means of lung books, as in the spiders. 



Harvestmen. The harvestmen, or daddy longlegs, are 

 similar to spiders, but with extremely long legs. They 

 frequent shady places, and live chiefly on small insects, 

 such as plant lice. 



Mites and Ticks. These are small and often degenerate 

 forms of Arachnids. Many of them are parasites, sucking 

 the blood of mammals, as ticks on dogs, cattle, and even 

 man. Among the mites is the "itch mite," which has 

 been made rare by the spread of "soap and civilization."
