Genus Eiitoinobrya Rondani 

 This genus is represented by five species in our fauna. 

 The Entomobrya have no scales and the segments of the 

 abdomen are unequal, the fourth segment being from three to 

 four times longer than the third. The ocelli are sixteen and 

 there are no postantennal organs. The mucrones are small 

 and always bear two teeth and sometimes a basal spine. The 

 ventral tube is well developed. The claws are two and always 

 armed. This genus is very common here. 



Key to the Genus Eiitoiaohri/a 

 A. Ocelli less than sixteen. 



B. Ocelli six; greenish gray; sui)erior claw ar)ned with 

 three teeth on the inner margin. scxociilata
