A. hermanni (Aiidoiiin, 1827) from Egypt, Neumann (l896) noted material 

 ~ from Ethiopia and Hoogstraal (1952A) from bird nests in Egypt, 

 We are still stvidying material referable to this species in view 

 of its possibly vinsatisf actory taxonomic criteria and species 

 statiis . 



A. striatus Bedford (l932A,193ii.) from weaver bird nests. Cape Prov- 

 " ince, South Africa, This species is said to be closely related 



to A, aequalis , but both axe in need of comparative biological 



and~morphological studies, 



A, transgariepinus (White, I846) from South Africa. A, kochi (Neu- 

 ~ mann, 1901 J from Basutoland possibly is a synonym, Berlese 

 (1913) reported specimens biting a child ard walking on the 

 wall of a bank in Italy. Hoogstraal (1952A) described biology 

 in Egyptian bat caves, Hoogstraal (195AC) noted presence in 

 Spain, A report on a stvidy of the life cycle, biology, and 

 morphology of each stage will be presented in a forthcoming 

 paper, 



Subgeneric classifications are not included for other groups in 

 this work because their status is still moot. The issue has been 

 forced in the genus Argas by the necessity for deciding whether to 

 refer to some species generically as Carios , Ogadenus , or Argaa , 

 Studies on this subject are presently under way and will be reported 

 more fully elsewhere.
