Only four families of Strepsiptera are given in the key for North America. 

 The authors have reduced my superfamilies to families and include Stylops In 

 the Xenidae. It would be impossible to run a male Strepsipteron to the order 

 in the key to the orders on page 6. In description of plate 8 Caenocholax is 

 placed in Xenidae.
