NÜTES ON ACARI 



FOURTH SERIES *) 



D R . A. C. OUDEMANS 



With PI. VIII -X. 



1. Acari of Cape-Coloiiy. 



The Amblyomma, mentioned in the Tijdschrift voor Entomologie, 

 vol. 39, p. 193, with which Dr. Ed. J. G. Everts preseuted me, 

 were caught in Cape-Oolony in 1881. The 4 <ƒ and 5 9 were 

 determined by Prof. Neumann, of Toulouse, as A. splendidum Gieb. 



2. Acari of Africa. 



On p. 193 of vol. 39 of the Tijdschrift voor Entomologie there 

 is question of two Hyalomma of unkoown locality. One of these 

 ticks I determined with Neumann 's Révision de la Familie des 

 Ixodidés as Amblyomma hippopotamense Denny Q. This tick is 

 only known as parasitic on Hippopotamus amphibius. I may sup- 

 pose, that my specimen, which I received from Dr. A. W. M. 

 van Hasselt, 1882, is original from Africa and from the same 

 animal.
