272 AN INTRODUCTION TO ENTOMOLOGY 



Figure 309, 2, represents an adult female that had shed her wings; 

 and Figure 309, 3, a nymph with well-developed wing pads. 



The two known American species are Zorotypus hubhardi and 

 Zorotypus snyderi. Detailed descriptions of each of the forms of 

 each of these species are given by Caudell ('20), and the external 

 anatomy of Zorotypus hubhardi is described by Crampton ('20 a), 

 who also discusses the relationships of the order Zoraptera to the 

 other orders of insects. 



The colonies of Zorotypus are found under the bark of logs and 

 stumps and frequently near the galleries of termites. For this 

 reason they were formerly believed to live as inquilines in the nests of 

 termites ; but recent observations do not support this view«
