The material was secured from the following three sources : 



Material received from other workers. 



Specimens of most of the studied species were acquired through the kind co-opera- 

 tion of many workers from various parts of the world, at the request of Dr. K. 

 Boratynski (see acknowledgements). Alcohol-preserved material of 15 species, 

 slide preparations mounted in " Berlese fluid " of one species (E. orariensis), and 

 dry material of another (E. buxi), were received. The " Berlese fluid " slides were 

 soaked in warm water until the mountant was dissolved and the specimens released. 

 The dry material was treated with 10% KOH for 24 hours, and the males were 

 gently dissected from their puparia with a finely pointed quill. 



Material collected in pupal stages. 



The writer was able to collect and breed the prepupae and pupae of 10 species ; 

 these were kept in glass tubes under laboratory conditions and produced adult
