others it is absent entirely, still others have the claws well 

 developed. The fureula is usually short and weak, in some 

 species it is so short that it is hard to see that there is any. 

 But two of the genera of this family have been found in this 

 region. 



Key to the Family PODURID^ 



A. Feet two-clawed ; two anal horns ; postantennal organ 

 present; ocelli, sixteen. Genus Achorutes 



AA. Feet with a single claw; no postantennal organ present; 

 two anal horns; ocelli, ten; fureula short but very slender. 



Genus Xenylln 



Genus Achorutes Templeton, Schaffer 

 The tarsi have two claws. The ocelli are sixteen, the antenna? 

 short and four-jointed. The post antenna] organ is present, 

 pseudocelli are absent. The body is cylindrical with the seg- 

 ments subequal. The fureula is stout with a heavy manubrium 

 and a thick dentes that tapers but little. The anal horns are 

 sometimes long and curving, while again hardly visible. 

 Our two species of this genus are both new.
