two large transparent anal suckers. Apparently he has not found 

 the female, certainly the deutonympha. 



Canestrini, 1879, only mentions the name. 



Megnin, 1880, only mentions the name in a „key". 



Haller, 1881, gives 

 an ample description 

 of the hypostome , ac- 

 companied by a tol- 

 erably good figure. 



Trouessart, 1885, 

 only mentions the name. 

 Canestrini, 1886, 

 shortly describes the 

 male and the deuto- 

 nympha. Of the female 

 he says „somiglia alla 

 precedente", which of 

 course is possible, but 

 I think there will be 

 any difference as to the 

 dorsal shields. This, 

 however, I cannot say 

 with any certainty, for 

 I did not examine deuto- 

 nymphae. 



Groult, 1887; his 

 description is too short 

 to recognize the species 

 sufficiently. 



Berlese, 1892, de- 

 lineates the male and 

 the female sufficiently to recognize them. He has well observed 

 that the „epimera antica inter sese" are „discreta". 



Berlese, 1897, only mentions the name in a „key". 

 Oudemans, 1905, calls the species Chauliacia securigera ^ and 

 gives good reasons for doing so. 



I do not like it necessary to describe the species amply ; 

 I only give here the explanation of my figures.
