Berlese, 1897, only mentions the name. 



Oudemans , 1905, calls the species Eustathia cultiifer , and 

 gives good grounds for doing so. 



I think it not necessary to give ample descriptions of the 

 deutonympha, female and male (other Stades I did not examine), 

 for the descriptions of Robin are exact enough , abandoned the 

 little inaccuracies quoted hereabove. 



I have only to explicate my figures. 



Fig. 1 : deutonympha, dorsal side. 



„ 2 : deutonympha, ventral side. 



„ 3 : female, dorsal side. 



„ 4 : female, ventral side. 



„ 5 : rostrum of female. This, however is exactly the same 

 in all the Stades. 



„ 6 : ventral side of hypostome and palpi. This is exactly 

 the same in all the Stades. 



„ 7 : tarsus IV. This is the same in all the legs , except 

 leg I which dorsally is provided with on olfactoric 

 hair, and in all the Stades. 



„ 8 : male, dorsal side. 



„ 9 : male, ventral side. 



„ 10 : hind part of ventral side, showing the enormous trans- 

 parent membranes surrounding and enlarging the 

 anal suckers.
